If you run a store on Magento, you have really been choosing between two versions of the same platform, whether or not anyone framed it that way. Adobe Commerce and Magento Open Source are built from one shared core. They look almost identical in the admin. But they produce very different bills, very different workloads for your team, and very different answers to the question every growing store eventually asks: is our platform helping us scale, or quietly holding us back?
In 2026 that question got harder, because Adobe changed what "Adobe Commerce" even means. So before you renew a license or commit to a migration, it is worth understanding what actually separates the two, and what Adobe's recent moves do to your roadmap.
Most comparison articles bury the one fact that explains everything else: both editions run the same open-source Magento core. The catalog, the checkout, the extension model, all shared. Magento Open Source is genuinely free to download and run, with no license fee, ever. Adobe Commerce takes that same core, adds a commercial layer of features, support, and optional managed hosting, and sells it as an annual license.
That is the whole distinction in one sentence. Everything below is a consequence of it.
For context, this is not a dying platform you would be betting on. Magento and Adobe Commerce still power roughly 7 to 8 percent of online stores worldwide, third behind WooCommerce and Shopify, and about a fifth of the top 1,000 US retailers run on it, according to Magento market-share data compiled for 2026. Store counts have thinned over the years, but the merchants who stay tend to be bigger.
The commercial layer is not a grab bag of nice-to-haves. A few pieces of it are the entire reason mid-market and B2B merchants pay for the edition at all.
The big one is B2B. Adobe Commerce ships company accounts, buyer roles, customer-specific catalogs and pricing, quote-to-order negotiation, and requisition lists out of the box. On Open Source you can build every one of those, but you are stitching together extensions and custom work, and that stops being cheap once the requirements get serious.
Then there is the merchandising and reporting layer. A drag-and-drop page builder your marketing team can use without filing a developer ticket. The ability to stage and schedule promotions and content changes in advance. Advanced reporting built on Adobe's business-intelligence tools. Gift cards and loyalty points, baked in rather than bolted on. On Open Source, each of these is a third-party extension or a custom build you own forever.
Here is where owners get surprised. Adobe does not publish Adobe Commerce pricing. It is quoted per merchant and scales with your gross merchandise value, so your license bill grows as your sales grow. Industry estimates put the cloud license somewhere around $40,000 a year at the entry tier and north of $190,000 for large merchants, with on-premise licenses starting lower, near $22,000, per independent 2026 license-cost breakdowns.
The license is only part of the bill. Once you add hosting, development, and support, total cost of ownership commonly runs two to three times the license fee alone, as pricing analyses of the platform note. Magento Open Source costs nothing to license. That does not make it free to run, which is the trap most owners fall into: you are simply paying your team and your hosting instead of paying Adobe.
This is the part that reshuffles the whole decision, and most of the comparison articles still ranking in search have not caught up to it.
In 2025 Adobe launched Adobe Commerce as a Cloud Service, a fully managed, software-as-a-service version of the platform. Instead of you or your agency owning servers, upgrades, and performance tuning, Adobe runs all of it and ships new features continuously. It is built on a composable, API-first architecture, which in plain terms means the storefront, catalog, and checkout can be developed and scaled independently rather than as one heavy monolith. It rolled out to general availability through 2025, starting in the Americas.
Adobe also introduced Adobe Commerce Optimizer, a lighter product that adds Adobe's search, product recommendations, and catalog tools to a store you already run without a full replatform, as detailed in coverage of Adobe's 2025 roadmap. Think of it as a bridge: a way to get some of Adobe's frontend firepower before you commit to the full SaaS move.
Why should you care? Two reasons. If you are on Adobe Commerce today, your upgrade path now points toward SaaS, and that changes how you should plan every customization. If you are on Open Source weighing a jump to Adobe, you are no longer just buying a license. You are deciding whether to hand off operational ownership of your store entirely.
The real Open Source versus Adobe Commerce decision is rarely about the feature checklist. It is about who carries the operational load.
Someone has to keep the platform patched. Adobe moved to a monthly security-patch cadence in 2026, a faster rhythm than the old quarterly model, and every one of those patches is work that someone on your side has to test and deploy on Open Source. Miss them and you become the store that gets skimmed at checkout. On Adobe Commerce cloud, and especially on the new SaaS edition, that maintenance is Adobe's job, which is a large part of what the ongoing Magento support and patching burden really costs when your own team owns it.
In our own migration and rescue work, this is the factor that actually decides it. We have extended Magento Open Source into a full B2B procurement platform for a merchant with the engineering capacity to own it, and we have rescued Adobe Commerce stores where the team assumed "managed" meant "hands-off" and learned otherwise. The honest rule of thumb: Open Source rewards teams that want control and have the people to use it. Adobe Commerce earns its price when offloading operations frees you to focus on selling.
Rough guidance, and yes, most owners get the threshold backwards.
If you do under a few million in revenue, sell mostly direct to consumers, and have or can hire a competent Magento development partner, Open Source is usually the right call. You get the identical core and keep the license money for growth. Stores this size rarely use enough of Adobe's commercial features to justify the fee.
If you run serious B2B, operate across many brands or regions, or simply do not want to staff platform operations, Adobe Commerce earns its keep. The B2B tooling alone can cost more to rebuild on Open Source than the license would have. And if never touching an upgrade again sounds like a relief, the new SaaS edition deserves a serious look, with the caveat that it is newer and moving heavy customizations onto it takes real planning.
Whichever way you lean, the migration itself is where the cost and the risk actually live. Moving between editions, or onto the SaaS platform, means auditing every extension and customization you depend on, because the ones quietly powering your business are also the ones most likely to break. A composable move in particular rewards treating it as a phased project rather than a big-bang cutover.
Platform choices like this go smoother with someone who has moved stores in both directions and seen where the bills and the breakages hide. That is the kind of work we do at Encomage: Magento and Adobe Commerce development, migrations, and the unglamorous maintenance that keeps a store fast and safe long after the decision is made.
