Open Source PIM Systems Compared (2026): AtroPIM, Pimcore, Akeneo CE and More
The open source PIMs most teams compare in 2026 are AtroPIM, Pimcore and Akeneo Community Edition. AtroPIM is GPLv3 with no revenue limit and a data model you configure, Pimcore is an open-core platform beyond PIM under its own POCL license, free in production up to €5 million in yearly revenue, and Akeneo Community Edition is a product-centric PIM under OSL-3.0 that you host and support yourself. Ergonode is no longer a maintained open source option, and Odoo is a suite rather than a dedicated PIM.
Open source, and the related open-core model, shows up in PIM selections once a team wants access to the code and is willing to run the system itself. Sometimes the reason is budget, sometimes the wish to control hosting and data, and sometimes a development team that prefers to extend a system rather than wait for a vendor's roadmap. Whatever the reason, the first decision is whether that model suits your organization, and only then which vendor fits. This guide explains what open source PIM is, what "free" really means, five systems that come up in selections, what you take on when you choose open source, and how to evaluate a project before you build on it.
What is open source PIM?
A PIM collects, enriches and publishes product information from one place. Descriptions, colors, images, videos, dimensions and manuals are maintained once, and the webshop and the other channels read from the PIM. A longer definition is in What is PIM?
Open source PIM is that software with the source code open. You can read it and change it (additions, connections, local behavior) under the project's license, and run it yourself. That work needs developers who know both the programming language and that specific PIM, because a generic web developer will not know how the system stores attributes or handles imports. Product data also makes a change riskier than in a normal app, because the system holds references across channels, platforms and assets: a change to how one attribute is stored can break an export that other channels depend on.
Open core is the closely related model: you get source access to a core, with commercial plugins or a paid edition around it. In both models, new features and extensions are frequently paid, so budget for those plugins, or for the team that builds the equivalent yourself. These systems are among the newer PIM products, and they often sit beside asset management and web content management in the same stack.
Most teams that look at open source come from spreadsheets. Excel is flexible and already on every desk, but it is weak at version control, quality checks and links to more than one system. Once the spreadsheet has become the system of record by accident, with several copies in circulation and nobody sure which one is current, a PIM is where that work moves to. See PIM vs Excel.
Is there free PIM software?
Yes, but three quite different things get called free PIM software, and they differ in what you receive and what you depend on:
- Open source. The license costs nothing and you get the code. Hosting, implementation, upgrades and the developers who know the system are yours to pay.
- Community edition (open core). A free core edition from a vendor that also sells a paid edition or commercial plugins. The free edition is working software, but the features you need later may sit on the paid side, so find out where that line is before you build on it.
- Free plan or trial of a hosted PIM. You use the vendor's SaaS without paying, but you get no source code. The vendor decides what the free plan covers and when you have to move to a paid one.
Only the first two give you the code. A free plan or trial is a way to try a product, and you are using it on the vendor's terms. In all three cases the word "free" applies to the license, while implementation, hosting and people still cost money. What a PIM costs once implementation and people are counted is in PIM costs compared.

Which open source PIM systems are there, and how do they compare?
These are the open source and open-core systems that come up in selections, plus Odoo as a suite option. Where a system has a vendor profile, the founding year, headquarters and the notes on fit and what to check come from that profile. License and release facts in the table come from each project's own repository and pricing pages, checked on 3 November 2026.
| System | License | Free in production | Paid route | Hosting | Latest activity |
|---|---|---|---|---|---|
| AtroPIM (AtroCore) | GPLv3 | Yes, no revenue limit | Premium modules, support from €240 a month, SaaS from €400 a month | Self-hosted or AtroCore SaaS | atropim 1.16.11, 21 October 2026 |
| Pimcore | Pimcore Open Core License (POCL) since 2025.1; GPLv3 up to 2024.4 | Up to €5 million total global revenue a year | Professional $9,900 a year, Enterprise $29,900 a year, PaaS on quote | Self-hosted, private cloud or Pimcore PaaS | 2026.3.3.1, 22 October 2026 |
| Akeneo Community Edition | OSL-3.0 | Yes, no revenue limit | Separate SaaS Product Cloud (Growth, Advanced, Premium) | Self-hosted only | v2026.5, 30 October 2026 |

| Odoo | LGPLv3 (Community repository) | Yes, Community code | Not documented here | Self-hosted Community, or Odoo's own offers | Active repository |
Akeneo
Akeneo is a French PIM, founded in 2013, built around product experience on channels the brand owns and channels it does not: ecommerce, mobile, print, social commerce and point of sale. It is open-core: a free Community Edition under the Open Software License 3.0 (OSL-3.0) next to the paid SaaS Product Cloud. You may read that the Community Edition is being sunset. Akeneo's own sources do not show that on 3 November 2026: the pim-community-dev repository published v2026.4 on 28 August and v2026.5 on 30 October 2026, and Akeneo's supported-versions page says the Community Edition is continuously supported. What ended is support for version 7 of the paid on-premise and PaaS editions, listed until 30 September 2026. So self-hosting Akeneo now means the free CE with community and partner support, and Akeneo's commercial product is the SaaS Product Cloud. The users it names are brands, manufacturers, distributors and retailers.
It fits brands, retailers and wholesalers that put multi-channel product experience, an API-first architecture, enrichment productivity and supplier onboarding first. The Product Cloud suits teams that are ready for SaaS. The Community Edition suits a technical team that wants a standard, product-centric model (families, attributes, variants) and accepts that hosting, upgrades and support are its own job. Akeneo does not replace a multi-domain MDM, and GS1, ETIM or digital product passport support needs explicit proof in a proof of concept, often through a partner.

Pimcore
Pimcore is an Austrian open-core platform, founded in 2009, that combines PIM, MDM, DAM, CDP, DXP/CMS and digital commerce, and publishes that data to websites, shops, apps and B2B or B2C portals. It is built to handle higher volumes.
It fits mid-market and enterprise manufacturers, brands and retailers with complex product data that want one extensible platform for PIM, asset management and content, the option to self-host or run a private cloud, and a technical team or integrator budget. Its ETIM and ECLASS classification is credible, which matters for manufacturers that sell through technical wholesale.
Open-core is not free at enterprise scale. Version 2024.4 was Pimcore's last GPLv3 release, and from 2025.1 the core is under the Pimcore Open Core License (POCL). Its LICENSE file allows free production use for organizations with total global revenue up to €5 million a year, and for qualifying non-profit and educational organizations. Above that you need a paid edition: the pricing page lists Professional at $9,900 and Enterprise at $29,900 a year, with the PaaS on quote. Modules such as Copilot, Workflow Automation, Datahub Simple REST, webhooks and the E-Commerce Framework are Enterprise only. Check the audit terms too, so you know at which point growth moves you onto a paid license. Ownership matters too: Pimcore announced on 27 August 2026 that Tenzing is buying the majority stake from Nordwind Growth, subject to antitrust approval. See what Tenzing buying Pimcore changes in the diligence checklist.

AtroPIM (AtroCore)
AtroPIM, founded in 2020, comes from AtroCore UG (haftungsbeschränkt), an independent software company in Regensburg, Germany. It is open source under GPLv3 and is also offered as SaaS, so you can choose between running it yourself and having it hosted. Around AtroPIM, AtroCore offers implementation, consultation, migration, support, integration and development.
It fits organizations, often European B2B or industrial companies, that need a highly configurable product and master data hub, value GPLv3 and self-hosting, and have internal developers or a trusted integrator. Native DAM and exchange modules for ETIM and BMEcat are available, and module and support pricing is transparent, which makes the cost easier to plan than with quote-only vendors. AtroCore's pricing page lists support from €240 a month, premium modules at €20 to €90 a month each in SaaS or a one-off €500 to €2,250 each on premises, and the SaaS Edition from €400 a month (checked 3 November 2026). The AtroPIM, Import and Export modules are free under GPLv3, without user limits.
Verify GS1 and GDSN claims before a retailer's data pool requirement decides your selection, because there is no public GDSN product. The supplier portal consists of permissions and process, so expect to set up supplier onboarding yourself instead of switching on a ready-made product.

Ergonode
Ergonode is a Polish PIM, founded in 2018, for centralizing, enriching and distributing product data across channels. It fits mid-market digital brands and retailers that want an enrichment interface people like to use, API and headless delivery, and a product DAM included, with published pricing.
Ergonode archived its open-source backend repository (OSL-3.0) on 13 February 2023 and now sells SaaS under a proprietary license, so it is no longer an open source option you can run yourself. If self-hosting is the reason you are reading this comparison, take it off your list or ask what the Enterprise plan's dedicated infrastructure covers. It is not proven as GS1-native or as a multi-domain MDM.
Odoo
Odoo is a modular suite that includes CRM and ERP functions, and companies tailor it module by module. Its Community code is published under LGPLv3. It suits small and mid-sized companies that want one integrated system instead of separate tools for sales, operations and product data. It can slow down when processing large datasets, so test it with your full catalog before you rely on it as the source for your channels. Odoo.
What you take on with open source
An open source PIM assumes a developer, or a team, who can implement it and keep it running. A small retailer without that skill will feel it quickly, usually at the first upgrade or the first integration that does not work as expected. The word "free" also misleads in another way: the more complete you want the tool to be, the larger the IT effort, or the more you spend on paid extensions, integrators and companion software. The main items are these:
Three more things need a place in the plan. The first is migration. Teams misjudge the volume and variety of the data they move, and a switch from a legacy system that looks like a straight transfer runs into formatting and integrity problems, which mean delays and unplanned cost. Put people and time on this phase, and test the migration with a real export from the old system early on.
The second is customization and training. Every field and workflow you add makes deployment longer and adds training, so be selective about what you build in the first release. Train staff before go-live, because people who do not know the system leave features unused, and agree on data entry standards across departments up front, so that marketing and purchasing fill in the same attribute in the same way.
The third is the license itself. Open source licenses set how you may use, change and distribute the code. Distributing a modified version without following the license, attribution included, can lead to legal trouble, which matters most if you plan to share your changes with partners or resell them as part of a service. Read the license before you build on it, and have someone with legal knowledge read it if you plan to distribute anything.
Advantages and disadvantages
The main advantage of open source is control. You can shape the software to the catalog and connect it to the platforms you already run, and API connectors are not limited to the list the PIM ships, because you can add the ones your other systems need. Licensing is typically cheaper than for a proprietary PIM, which is why teams with a tight license budget look here first. For a company with its own developers and unusual requirements, that combination can make open source the most practical route.
The disadvantages mirror those advantages. You need people who know the system, in house or at a partner, and compatible extensions and connectors are harder to find than for a proprietary PIM. Training and support often come from community forums and documentation, with less in-person help from a vendor. A large forum does not guarantee fast answers either, because response quality differs per platform and per question. Development leans on volunteer contributors, so timelines are uneven, and a fix or feature you need can take a long time to arrive unless you build it yourself.
How to evaluate a free or open source PIM
Write down what you need
Before you compare tools, write down the goal (more accurate product data, faster time to market, better collaboration between teams), where the current process hurts (several spreadsheets, inconsistent formats, slow updates), how technical the team is, and what the PIM must connect to: ERP, ecommerce platform, CRM. That description is what you hold every candidate against.
Check the five features that separate a tool from a toy
A free tool has to cover the basics before anything else counts. Check these features in every candidate:
- Import and export in formats such as CSV and XML, with bulk uploads, for migration and for sharing data with partners.
- Collaboration: comments, version control and role-based permissions, so marketing can work on descriptions while another team updates other fields.
- Integration: an API, connectors for platforms such as Shopify, WooCommerce or Salesforce, data mapping between systems, and documentation for the connection work.
- Scale and customization: room for more users and more product data, and options to fit the tool to your workflow.
- Usability and training: a layout people find their way around in, and tutorials, documentation or community forums for onboarding.
Check security
Look for encryption at rest and in transit, granular role-based access (so people see only the product details, pricing or supplier contracts their job needs), regular security audits, compliance with the data protection rules that apply to you, such as GDPR or CCPA, and automatic backups with a recovery path. Open source is not less secure by nature, but nobody runs the risk assessment for you, so do it before go-live.
Check that the project will last
Open source projects can stall or be abandoned, leaving you with data risks and compatibility problems. Check how often updates ship and how many people contribute, the size and activity of the user community, whether the project has stalled before, and the quality of the documentation. After go-live, a quarterly look at the forums and release notes shows whether the project still gets the support you depend on. With open core, check who owns the vendor as well.
Test scale before go-live
A feature list that calls a system scalable tells you little about how it will handle your catalog. Compare your current data load with the growth you expect, test performance under simulated peak conditions, and make sure the team can tune the system as volume grows.
What the PIM itself still gives you
Once the catalog is large, changes often and feeds several channels, the operating gains of an open source PIM are the same as with any other PIM. A product is entered once, and imports follow one set of rules, which keeps quality stable no matter which supplier or colleague delivered the data. Channels get the same completed information, in the tone each channel needs, so the webshop and a marketplace no longer tell different stories about the same item.
The daily work gets lighter as well. There is less copying between files and less time spent hunting for the current value, and print can be fed from the same record through InDesign. Linked systems and a strict workflow move product information faster from supplier to channel. And when the information matches what the customer expected, returns drop.
How we evaluated
We compared the systems on license, what is free in production, the paid route, hosting and recent release activity. License facts come only from each project's own LICENSE file, its release or tag pages and its pricing or editions pages, all opened on 3 November 2026. Fit notes come from our vendor profiles. Where a source did not state something, we left it out or wrote "not documented". PIMvendors is an independent PIM selection platform, and the systems are not ranked.

Frequently asked questions
What is open source PIM?
Open source PIM is product information management software whose source code you may read, change and run yourself under the project's license. It does the same job as any PIM: it collects, enriches and publishes product information from one place. You or a partner take on hosting, upgrades and integration.
Is there free PIM software?
Yes, in three forms: open source PIMs, free community editions of open-core products, and free plans or trials of hosted PIMs. Only the first two give you the source code. A free license does not make the project free: all three still cost money in hosting, implementation, plugins or the people who run them.
What is the difference between open source and open core PIM?
Open source gives you the code to read and change. Open core gives you the same source access to a core edition, with commercial plugins or a paid edition around it. In both models, features beyond the core are often paid.
Which open source PIM systems are there?
The three that come up most are AtroPIM from AtroCore (GPLv3), Pimcore (open core under its own Pimcore Open Core License, POCL) and Akeneo Community Edition (OSL-3.0), all checked on 3 November 2026. Ergonode archived its open-source repository in February 2023. Odoo, a modular suite under LGPLv3 with CRM and ERP functions, also comes up for smaller companies that want one integrated system.
What is the best open source PIM?
It depends on your scope and your team. AtroPIM fits a configurable, self-hosted product data hub for B2B under GPLv3. Pimcore fits one extensible platform for PIM, MDM, DAM and content, free in production only up to €5 million in yearly revenue. Akeneo Community Edition fits a standard, product-centric PIM under OSL-3.0 with community support. All three assume developers, in house or at a partner.
Who should choose an open source PIM?
A team with developers, in house or at a partner, who can implement the system and keep it running. A small retailer without that skill will feel the gap.
What should a free PIM be able to do?
At minimum: bulk import and export in formats such as CSV and XML, role-based permissions and version control, an API or connectors to your shop, ERP and CRM, and backups. Check the security basics too: encryption, access control and regular audits.
How do you know an open source PIM project will last?
Look at how often updates ship, how active the contributors and user community are, and whether the project has stalled before. After go-live, read the forums and release notes every quarter.
