Ask any US retailer who has lived through a replatforming and they will tell you that the Magento family is the platform most likely to inspire both love and resentment in the same conversation. Magento Open Source and Adobe Commerce share roughly 90 percent of the same code, but the gap between what each one costs, what each one ships with, and who each one is actually built for keeps catching teams off guard. The honest comparison below is meant for the decision moment, after the demos and before the contract, when you need a clear picture of where the line sits and what crosses it.
In short
- Same engine, different package. Adobe Commerce is Magento Open Source plus a paid Adobe stack on top, not a different product.
- Open Source is free to download, but a real production deployment lands between $80,000 and $250,000 per year once hosting, dev, and security are honest.
- Adobe Commerce licensing for a US merchant typically runs $22,000 to $250,000 per year depending on gross merchandise value, before implementation.
- The features that justify Adobe Commerce are B2B quoting, advanced segmentation, page builder with staging, Adobe Sensei AI, and a real support line, not the core checkout.
- Pick Open Source if you have or hire serious PHP and DevOps muscle. Pick Adobe Commerce if your roadmap needs B2B, omnichannel via Adobe Experience Cloud, or 24×7 vendor support.
If you are still deciding the underlying architecture, the broader e-commerce platform selection guide walks through how Magento sits next to Shopify, BigCommerce, and the headless contenders. This piece zooms into the Magento decision itself.
What you actually get with each edition
Magento Open Source, formerly Magento Community Edition, is a PHP application released under the Open Software License 3.0. You download it, you install it on infrastructure you control, and you operate it the same way you would any large open source application. The codebase is on GitHub, the release cadence is roughly two minor versions per year, and the long term support window currently runs three years after a major release.
Adobe Commerce is the same core codebase with additional modules layered on top, plus a managed cloud option called Adobe Commerce Cloud that wraps the application in AWS infrastructure, Fastly CDN, and New Relic monitoring. The license is commercial, paid yearly, and tiered against either gross merchandise value or average order value depending on the contract you sign.
The shared core is large. Catalog management, multi store, multi website, multi currency, checkout, payment integration, tax engine, shipping engine, order management primitives, EAV attribute system, indexer, and the entire admin panel all live in the open source repository. A reasonable rule of thumb is that if a feature is in the merchant manual and not flagged as Commerce only, it ships in both editions.
What Adobe Commerce adds on top of that shared core falls into six buckets. Content tools, where Page Builder lets a non developer drag and drop layouts and staging lets you preview a campaign before it goes live. B2B features, including company accounts, shared catalogs, negotiable quoting, and purchase approval workflows. Customer segmentation, where rules engine attributes drive dynamic blocks, price rules, and personalised email content. Business intelligence, through a hosted dashboard product that pulls from the Commerce database. Adobe Sensei powered features such as product recommendations and live search. Finally, the cloud platform itself, which on the Cloud SKU bundles managed infrastructure, deployment tooling, and a support SLA.
The real cost of each path in 2026
This is where most teams get burned, because the sticker price on either edition tells only a small part of the story. The honest table below reflects mid market US retailers in 2026, with figures pulled from public Adobe rate cards, partner pricing, and the cost stacks our editorial team sees in actual implementations.
| Cost line | Magento Open Source | Adobe Commerce on premise | Adobe Commerce Cloud |
|---|---|---|---|
| License fee | $0 | $22,000 to $125,000 per year | $40,000 to $190,000 per year |
| Hosting | $12,000 to $80,000 per year | $12,000 to $80,000 per year | Included |
| CDN and WAF | $3,600 to $24,000 per year | $3,600 to $24,000 per year | Fastly included |
| Implementation, first build | $60,000 to $250,000 | $90,000 to $400,000 | $90,000 to $400,000 |
| Ongoing dev and support | $50,000 to $180,000 per year | $60,000 to $200,000 per year | $60,000 to $200,000 per year |
| Security patches and audits | $8,000 to $25,000 per year | Included in license | Included in license |
| Vendor support SLA | Community only | 24×7, 1 hour P1 | 24×7, 1 hour P1, infra included |
Two numbers in that table deserve a closer look. The first is the implementation range. A simple US merchant with a clean catalog, two payment gateways, and one warehouse can land an Open Source build at the low end. A merchant with B2B, three ERPs to integrate, and a custom checkout will spend toward the high end on either edition, and the gap between Open Source and Commerce narrows because integration work dominates. The second number is the security line. Magento patches arrive on a published schedule, but Open Source merchants are responsible for testing, deploying, and verifying each one. The cost shown is what a typical agency charges for a managed patching program, and skipping it is the single most common reason an Open Source store ends up on an attacker disclosure list.
Adobe Commerce licensing in 2026 is tiered against gross merchandise value, with three bands that roughly cover up to $5 million, $5 million to $25 million, and above $25 million. Adobe does not publish the rate card publicly, but the figures above are the range our editorial team has confirmed across recent renewals. The Cloud SKU sits roughly 30 to 50 percent above the on premise license because it bundles infrastructure that you would otherwise buy from AWS directly. There is no published self service way to buy either tier. Every deal closes through Adobe sales or an Adobe Solution Partner.
Where the two editions feel different day to day
Code wise the editions are close. Day to day they feel different in three places.
The first is the admin panel. A merchandiser logging into Adobe Commerce sees the same menu structure as Open Source, but several screens have additional controls. The catalog page has a staging tab, the customers page exposes segments, and the marketing section gains rules for related products driven by Sensei. The Page Builder is the most visible difference. A merchandiser building a landing page in Open Source drops blocks of HTML or uses a third party page builder extension. The same merchandiser in Commerce drags rows, columns, and content types directly in the admin, previews on multiple breakpoints, and schedules the page through staging. Most marketing teams notice the difference within two weeks of go live.
The second is the developer experience on the cloud SKU. Adobe Commerce Cloud ships with a git based deployment pipeline, ephemeral environments per branch, and a magento-cloud command line tool that handles environment promotion. An engineer working on a complex feature can spin up a clone of production with sanitised data in roughly ten minutes. Open Source teams build the same workflow themselves, usually with a combination of Bitbucket pipelines, Terraform, and a homegrown environment manager. The capability is reachable on Open Source, but it is not free and it is not fast to set up.
The third is what happens when something breaks at 3am. An Open Source merchant calls their agency, which calls the on call engineer, who logs into the server and starts a triage that may or may not involve a Magento expert. An Adobe Commerce merchant opens a P1 ticket and gets a senior engineer with access to internal logs and a direct line to product engineering. The mean time to resolution on a payment outage is usually two to four times shorter under Adobe support, and for many merchants the avoided revenue loss on a single Black Friday incident covers half the annual license fee.
Who each edition is actually for
The clean way to choose between the two is to start with the things only Adobe Commerce does well, then work backward.
If your business needs serious B2B, Adobe Commerce is the answer. The B2B suite, including company accounts, shared catalogs by company, negotiable quoting, purchase approval workflows, and account hierarchies, is a Commerce only module. There are third party B2B extensions for Open Source, but none of them match the depth of the Commerce module and very few of them have a stable upgrade path across major versions.
If your roadmap depends on Adobe Experience Cloud integration, Adobe Commerce is the answer. The Commerce edition has first party connectors into Adobe Experience Manager, Adobe Analytics, Adobe Target, and Adobe Journey Optimizer. The connectors exist as Open Source projects too, but the maintained, vendor supported versions are Commerce only and the data flows are pre wired in the Commerce admin.
If your team is small and your engineering bench is shallow, Adobe Commerce Cloud is worth the premium. The cloud edition removes the entire infrastructure and deployment burden. A team of three engineers can run a $50 million Commerce Cloud store. The same store on Open Source typically needs five to seven engineers because the operations work does not disappear, it just moves to your payroll.
If none of those three apply, Magento Open Source is the honest choice. A merchant doing pure direct to consumer apparel, with a US only audience, no B2B needs, and a roadmap that does not pivot through the Adobe stack, gets nearly everything they need from Open Source and can spend the saved license fee on the features they actually want to build.
Two patterns we see often that argue against either edition. The first is the merchant whose true need is a fast launch with a small catalog and a familiar admin. That merchant is usually better served by Shopify or BigCommerce, regardless of how persuasive the Magento ecosystem looks on paper. The second is the merchant whose front end vision is a fully headless storefront with a different commerce backend per region. That merchant should look at a composable commerce stack rather than either Magento edition, because both Open Source and Commerce assume the Magento storefront or PWA Studio is in the picture.
Hosting, security, and operations
The Magento application is heavy. A modest US store with 50,000 SKUs and 5,000 orders per day usually needs at least 16 GB of memory across the web nodes, a separate Elasticsearch or OpenSearch cluster, a dedicated database node, a Redis or Valkey instance for sessions and full page cache, and a queue worker for async tasks. That stack runs comfortably on AWS for around $1,200 per month on the Open Source side, but tuning it for Black Friday traffic without falling over is its own discipline.
Adobe Commerce Cloud abstracts most of that decision making. The platform allocates instance sizes based on your contracted plan, scales the web tier within a band you define, and applies Fastly in front of every store. There is a real ceiling on what you can change, which trades flexibility for predictability. For the architectural detail on running Magento on AWS yourself, including reserved instance strategy and the autoscaling patterns that actually work under flash sale conditions, the Magento on AWS without a six figure surprise deep dive is the companion read.
Security on Open Source is a real responsibility. Magento publishes security advisories four to six times per year, each one carrying a CVE list and a patch. The merchant or their agency is on the hook to apply the patch within days, not weeks, because the published CVE is also a recipe for attackers. Adobe Commerce ships the same patches through the cloud pipeline on the cloud SKU and through the same package on premise, but the support contract usually includes a managed patching service that takes the operational burden off the merchant. If you run Open Source, budget for a patch management retainer with a Magento focused agency. Skipping that line is the most expensive false economy in the entire stack.
The extension marketplace question
Both editions share the Adobe Commerce Marketplace, formerly Magento Marketplace, where roughly 3,500 paid and free extensions are listed in 2026. Most extensions install on either edition, with a handful of Commerce only modules that hook into staging, segmentation, or B2B. A typical Open Source build pulls in 15 to 30 extensions for things like one step checkout, advanced search, multi vendor fulfillment, and ERP connectors. A typical Commerce build pulls in 10 to 20, because some of the commonly bought extensions are already in the Commerce edition.
The extension ecosystem is one of Magento’s real advantages over newer platforms, but it is also a maintenance burden. Each extension is a code dependency that needs to keep up with Magento major versions, and the gap between a major release and a stable extension catalog is usually three to six months. Teams that depend on a thick extension stack should plan upgrade cycles around their slowest extension, not around the Magento release calendar. For a sober look at how to evaluate an extension before buying it, including a checklist for license terms, support windows, and code quality signals, the Magento extension marketplace explained for store owners is the practical companion guide.
Examples from US retailers
Three short profiles show how the decision plays out.
Mid market apparel brand, Los Angeles. Annual GMV around $18 million, six person engineering team, US only audience, no B2B. The brand ran Magento Open Source on AWS for five years, applied patches on a quarterly cadence with a Magento agency on retainer, and spent roughly $140,000 per year on platform total cost. When they renewed the agency contract in 2026 they priced Adobe Commerce Cloud and concluded the additional $90,000 in license and infrastructure would not pay for itself given their current roadmap. They stayed on Open Source. The right call for that profile.
Industrial distributor, Cleveland. Annual GMV around $42 million, mostly through 1,200 trade accounts with negotiated pricing, purchase approval workflows, and customer specific catalogs. The team tried to build the B2B layer on Open Source using a third party extension and ran into version compatibility issues every major release. After the second failed upgrade they switched to Adobe Commerce on premise. The license added $95,000 per year, but the B2B module replaced four custom modules and the upgrade pain disappeared. Net cost was a wash within 18 months because the maintenance line dropped by roughly the same amount.
Direct to consumer beauty brand, Brooklyn. Annual GMV around $9 million, three person engineering team that did not exist 18 months ago. The brand chose Adobe Commerce Cloud at launch on the recommendation of their integrator and never regretted it. The license is steep at their revenue level, but the team has not had to think about infrastructure once, the deployment pipeline is in place out of the box, and the founder spent the first year on growth instead of DevOps. The right call for a team that does not want to operate infrastructure.
Migration paths and gotchas
Most decisions about Magento happen at a fork in the road. You are either picking a new platform, replatforming from something else, or moving between the two editions. Each path has a different shape.
Moving from Magento 1 to Magento 2, in either edition, is still a real project in 2026 because some merchants are only now ending their long tail M1 lifecycle. The migration is not an upgrade, it is a fresh build with a data migration tool that brings catalog, customers, and orders across. Budget six to nine months and expect a partial rebuild of every customisation.
Moving from Magento Open Source to Adobe Commerce in place is the easiest path. The data model is identical, so the move is essentially a license change plus a deployment of the Commerce modules. Allow three to five weeks for an experienced agency, plus a quarter to absorb the new admin features before training your merchandisers.
Moving from Adobe Commerce to Open Source is harder than the reverse because any Commerce only feature you depend on, such as staging, segmentation, or B2B, needs a replacement or a custom rebuild. If you got hooked on Page Builder, plan for a long content migration before you can sunset the Commerce license.
Moving from Shopify Plus to either Magento edition is the migration we see most often in 2026, usually driven by merchants who have outgrown Shopify’s limits on checkout customisation or B2B. The technical migration is straightforward with the right tooling, but the cultural change is bigger than people expect because Shopify shields merchants from much of the work that Magento exposes. Teams that survive the transition usually hire a dedicated Magento person before go live, not after.
One gotcha that affects both directions is the channel mix. A Magento store that also sells through Amazon and a TikTok Shop usually needs a channel manager, and the integration patterns vary by channel. The creator affiliate programs on TikTok Shop guide covers the affiliate side of that channel for context on how the commerce engine behind a TikTok integration usually has to look.
Headless, PWA Studio, and the front end question
One question that comes up in almost every Magento decision in 2026 is whether to run the platform headless. Both editions support a GraphQL API that covers most of the storefront read and write surface, and both editions ship with PWA Studio, the React based front end framework that Adobe maintains. Choosing headless changes the calculus on edition selection in two ways worth naming.
First, headless does not lean toward one edition. The GraphQL coverage is identical on Open Source and Commerce, and the Commerce only modules expose their own schema extensions when you license them. A headless team using Next.js or Nuxt against the Magento backend gets the same data surface from either edition. The choice still comes down to admin features, B2B, and support.
Second, headless raises the developer headcount on Open Source more than it does on Commerce Cloud. A headless storefront is a separate deployable, a separate caching layer, and a separate observability problem. On Commerce Cloud the platform team handles the back end half of that work, which often closes the gap between needing five engineers and needing three. On Open Source the team owns both sides, and the team size scales accordingly.
PWA Studio itself is now considered a reference implementation rather than the dominant front end. Most US teams that go headless in 2026 pick a custom Next.js storefront, drive it from Magento GraphQL, and treat PWA Studio as inspiration rather than starting point. Adobe has signaled that PWA Studio will continue to receive maintenance but not heavy new features, which is the right read for procurement teams sizing a multi year roadmap.
Decision shortcut
If you only have two minutes to make the call, score yourself on five questions. Each yes pushes you toward Adobe Commerce. Each no leaves you in Open Source territory.
- Do you sell to other businesses with negotiated pricing or approval workflows? If yes, Adobe Commerce.
- Will your marketing team need staged content, segmentation, or visual page building inside the platform? If yes, Adobe Commerce.
- Are you committed to other Adobe Experience Cloud products such as Analytics or Target? If yes, Adobe Commerce.
- Is your engineering team smaller than four people and unlikely to grow soon? If yes, Adobe Commerce Cloud specifically.
- Do you need a 24×7 vendor support line with a contractual SLA rather than a community forum and an agency on retainer? If yes, Adobe Commerce.
Three or more yes answers and Adobe Commerce earns the license fee. Two or fewer and Magento Open Source is almost always the more honest choice. For teams that are still weighing Magento against entirely different stacks, the e-commerce platform selection guide is the right framework before you commit to either edition. The official Adobe Commerce product page and the public Magento Open Source repository on GitHub are useful to bookmark for procurement and engineering reviews.
FAQ
Is Magento Open Source really free?
The software license costs nothing, but a production deployment is not free. Hosting, CDN, security patching, and development together usually land between $80,000 and $250,000 per year for a US mid market store. The license fee is the smallest line on the bill.
How much does Adobe Commerce cost in the US in 2026?
Adobe does not publish public pricing, but typical license tiers run $22,000 to $125,000 per year for on premise and $40,000 to $190,000 per year for the cloud edition, tiered by gross merchandise value. Implementation and ongoing dev are separate.
Can I start on Open Source and migrate to Adobe Commerce later?
Yes, and this is one of the cleanest migrations in the commerce world. The data model is identical, so the move is mostly a license change plus a deployment of the additional Commerce modules. Three to five weeks of agency time is a fair budget.
Is Page Builder available on Open Source?
No. Page Builder is an Adobe Commerce only feature. Open Source merchants either use third party page builder extensions, which vary in quality and upgrade reliability, or accept that landing pages are built by developers.
What about B2B features?
The full B2B suite, including company accounts, shared catalogs, negotiable quoting, and purchase approval workflows, is Adobe Commerce only. There are partial B2B extensions for Open Source on the marketplace, but none match the depth of the first party module.
How big a team do I need to run Magento Open Source?
For a US store doing $10 million to $50 million in GMV, plan for five to seven dedicated engineers if you self host. Adobe Commerce Cloud at the same revenue can be run with three engineers because infrastructure and deployment work is bundled into the platform.
What is the upgrade cadence?
Magento issues roughly two minor versions per year and a major version every two to three years. Both editions follow the same cadence. The long term support window currently runs three years after a major release.
Does Adobe Commerce include hosting?
Only on the Cloud SKU. Adobe Commerce on premise is just the license, and you provision the infrastructure yourself, usually on AWS, Azure, or a managed Magento host. Adobe Commerce Cloud bundles AWS, Fastly CDN, and New Relic monitoring into the license.
