Turbo EA competes with established Enterprise Architecture Management products including SAP LeanIX, Ardoq, Bizzdesign, Avolution Abacus and MEGA HOPEX. This page sets out what can honestly be compared without guessing, and it is equally clear about the situations in which one of those products is the better answer for you.
How this comparison is made
Vendor comparison pages are usually written by the vendor who wins, so this one states its rules up front. Claims about Turbo EA are made freely, because you can verify every one of them against the published source code, the documentation and a running instance. Claims about the other products are deliberately limited to what is true of commercial software by definition, such as being proprietary and being priced per engagement.
That rule has one visible consequence. Only the Turbo EA column carries a positive value, and the other column mostly tells you what to ask each vendor rather than answering for them. A cell that does not answer means we did not verify it, never that a product lacks the capability. No pricing figure for any other vendor appears anywhere on this page, and none of the five was independently assessed for this comparison. Treat this as a starting point for your own evaluation, not as a substitute for one. Corrections are welcome through the contact form.
Turbo EA is a self-hosted alternative to commercial Enterprise Architecture Management platforms. The core is free under the Functional Source License (FSL-1.1-MIT), it runs as Docker containers on infrastructure you control, and it has no per-seat licensing, so an unlimited number of architects and stakeholders can use it at no cost. It bundles three capabilities that commercial EA suites commonly sell as separate modules or separate products: native BPMN 2.0 process modelling, project and portfolio management, and a TOGAF Statement of Architecture Work editor with sign-off workflows. A commercial platform remains the better choice when you need contractual support with a service level agreement, a supplier to answer your procurement and security questionnaires, an implementation partner ecosystem, or analyst coverage to support an internal decision.
Fifteen dimensions, each chosen because it is a property of Turbo EA that you can verify for yourself. The second column does not rate the other products. It tells you what to establish with each vendor before you decide.
| Dimension | Turbo EA | Commercial EA platforms |
|---|---|---|
| Licence | Source-availableFSL-1.1-MIT, published on GitHub. Each release converts to MIT two years after publication. | Proprietary commercial licence. |
| Source code | PublicReadable, modifiable and forkable. | Not published. |
| Cost of the core | FreeNo registration, no trial period, no feature limitation. | Commercial subscription. Pricing is quoted per engagement, so ask each vendor directly. |
| Cost of adding a user | ZeroNo per-seat licensing and no user cap. | Ask how users are counted, and whether read-only stakeholders are charged. |
| Deployment | Self-hostedDocker Compose on your own infrastructure. Air-gap capable. | Confirm which deployment models are offered to you, and on which editions. |
| Where your architecture data lives | Your serversIn a PostgreSQL database you control. | Confirm the hosting region and the data-processing terms in the contract. |
| Data sent back to the supplier | NoneNeither the application nor an installed extension transmits usage or architecture data. | Review each supplier’s data-processing agreement. |
| Metamodel configurability | Admin-configurableCard types, subtypes, fields and relation types are stored as data, not code. Ships with 13 card types and 45 relation types. | Ask for a live demonstration of an administrator editing the metamodel, rather than a description of it. |
| BPMN 2.0 process modelling | In the coreNative editor with versioning, sign-offs, and element links to applications and IT components. | Ask whether process modelling is inside your quote or priced as a separate product or module. |
| Project and portfolio management | In the corePortfolio Gantt, work breakdown structure, Kanban, budget tracking and a risk register. | Ask whether portfolio delivery is included, sold separately, or expected to live in a different tool. |
| TOGAF Statement of Architecture Work | In the coreRich-text editor with version history, sign-off requests and DOCX export. | Ask how architecture governance artefacts are authored and signed off. |
| AI agent access over MCP | Built inRead and write, under each user’s own permissions rather than a shared service account. | Every vendor is shipping AI features quickly, so check current release notes rather than any comparison page. |
| Getting your data out | UnrestrictedExcel and CSV export, REST API, OData feeds, DOCX export, and direct access to your own database. | Establish the bulk export formats and API access before signing, not afterwards. |
| Support and accountability | No SLA on the free coreCommunity support and GitHub issues. Paid implementation and advisory are available from the author, as consulting rather than a support contract. | Commercial support is normally included in the subscription, with a contractual response target and an account team. |
| Roadmap influence | One principal maintainerSponsored development can place a specific requirement on the roadmap on a committed timeline. | Established product organisations with formal roadmap and customer advisory processes. |
Turbo EA is not the right answer for every organisation. These are the situations in which one of the commercial platforms will serve you better, and pretending otherwise would waste your time.
If an outage or a defect has to be answered inside a contractual window, you need a supplier with a support organisation and a service level agreement behind it. Turbo EA offers community support on GitHub and paid consulting from the author, and neither of those is a support contract.
Many enterprises require a supplier to complete security questionnaires, hold recognised certifications, carry insurance and pass a vendor risk assessment. Established vendors have teams for exactly this. Turbo EA is software you run yourself, so the certifications that apply are the ones covering your own hosting environment.
Turbo EA needs a Docker host, a PostgreSQL database, backups, TLS termination and someone to apply upgrades. If your organisation has no platform team willing to own that, a hosted service removes real work that somebody would otherwise have to do.
Some decisions are settled by an analyst quadrant or wave rather than by a hands-on evaluation. Turbo EA does not appear in analyst coverage. If that is how your organisation chooses software, it is a genuine reason to pick a covered vendor.
Large programmes are often staffed through system integrators who already have certified consultants on a given platform. Turbo EA has one principal maintainer, so implementation capacity is bounded by his availability rather than by a partner network.
Turbo EA is maintained by one person. The source is public and the licence lets you fork it, which limits the downside, but a single-maintainer project carries a different continuity profile from a funded product organisation. Weigh that honestly against the cost and the lock-in you avoid.
Each of these is a capable, established Enterprise Architecture Management product with real customers. What follows is limited to what Turbo EA specifically offers in relation to each one, such as whether a migration path exists today.
A widely adopted commercial EA management platform, now part of SAP. It is the tool Turbo EA is most often compared with, and it is the only one for which Turbo EA ships a dedicated importer today, with field mapping and a staged review before anything is written. The author of Turbo EA holds an SAP LeanIX certification.
A commercial EA management platform with a strong emphasis on data-driven architecture and graph-based analysis. An Ardoq importer is on the Turbo EA roadmap and is not available yet. In the meantime an Ardoq export to Excel or CSV loads through the Turbo EA bulk importer with field mapping and a preview.
A commercial platform with deep ArchiMate modelling heritage. A Bizzdesign importer is on the Turbo EA roadmap. If formal ArchiMate conformance is a hard requirement for your practice, evaluate that requirement directly against each candidate rather than taking either side of this comparison on trust.
A commercial EA platform known for quantitative analysis and modelling breadth. Turbo EA does not offer a dedicated Abacus importer, so a migration would go through Excel or CSV export and the Turbo EA bulk importer.
A long-established commercial platform, frequently deployed where enterprise architecture sits alongside governance, risk and compliance. A MEGA importer is on the Turbo EA roadmap. If integrated GRC is part of your requirement, that is worth evaluating separately from the EA repository itself.
Turbo EA ships a dedicated LeanIX importer with field mapping and a staged review, so you can see exactly what will be created before anything is committed. Importers for Ardoq, MEGA and Bizzdesign are on the roadmap and are not available yet. Any product that exports to Excel or CSV can be loaded today through the bulk importer, which supports field mapping and a preview, so a migration can be rehearsed as many times as it takes. Migration and metamodel design are also available as a paid engagement if you would rather not run it yourself.
Yes. Turbo EA covers the same core ground as a commercial EA management platform, namely an application and technology inventory, a configurable metamodel, capability mapping, lifecycle and cost reporting, and dependency analysis. It differs in being self-hosted and free to licence, with no per-seat cost, and it ships a dedicated LeanIX importer with field mapping and a staged review. Whether it is the right alternative for you depends mostly on whether you can host it and whether you need a contractual support relationship.
Turbo EA is one. It is published on GitHub under the Functional Source License (FSL-1.1-MIT), which permits any internal use and converts each release to MIT two years after publication, while prohibiting resale as a competing product. It deploys with Docker Compose, and the core is free with no registration, no trial period and no feature limitation. It covers the EA repository, more than ten interactive reports, native BPMN 2.0 process modelling, project portfolio management and TOGAF governance artefacts.
The Turbo EA core costs nothing to licence, so your cost is the infrastructure you already operate plus the time your team spends. Optional commercial extensions and paid consulting are available but are never required. This page quotes no prices for other vendors, because commercial EA platforms are priced per engagement and inventing figures would make the comparison worthless.
Turbo EA has one principal maintainer, so there is no support contract and no service level agreement behind the free core, and no partner network to staff a large programme. It does not appear in analyst coverage, which matters in organisations that decide by quadrant. It also requires somebody in-house to run Docker, PostgreSQL, backups and upgrades. Paid implementation, extension development and advisory are available from the author, but that is a consulting relationship rather than a vendor support contract.
