FLOW vs Bizagi: the model is not the living record
Short answer: Bizagi draws the process and builds the app that runs it, and both are done well. What Bizagi does not do is stay the true, governed version once the model hands off to execution, which is exactly when the diagram and the reality start to drift apart. FLOW owns that middle: one scenario-aware master with owners, sign-off, and an audit trail that stays current after the diagram and feeds whatever executes. If you need a modeler, use Bizagi. If you need the living record, that is FLOW. Here is the honest version, including when to pick Bizagi.
If you searched for a Bizagi comparison, you are probably weighing whether a BPMN modeling and low-code automation suite is the right home for your processes, or whether you need something that sits a layer above it. This page lays out the difference fairly. Bizagi is a capable, widely used product, and where it is strong we say so.
What Bizagi is genuinely good at
Modeling, and building the app that runs the model. Bizagi Modeler is a strong, free BPMN tool that a lot of analysts already know, and it produces clean, standards-based diagrams. The automation platform then turns those models into low-code workflow applications with forms, rules, and integrations. That is a real capability: if your team has developers and a specific process to automate end to end, Bizagi takes you from a diagram to a running application without starting from raw code. FLOW does not try to be a modeler or a low-code app builder, and we are not pretending otherwise. This page is about one specific job that model-then-build tools leave open: keeping the process true after the handoff.
Where Bizagi ends
A model is a snapshot. The day you finish the diagram, it describes the process. The day after you build and ship the automated app, the app runs and the model quietly stops matching it. Change a rule in the running system, add a new exception in real operations, or move an approval, and the picture on the wall is now wrong. That is the structural gap in model-then-handoff: the diagram and reality decouple, and there is no single governed master that both people and agents can trust as the truth. There is also no scenario engine underneath the model. Show and hide logic in a form is not one master that resolves to the exact route per situation: a standard case, a regulated exception, and an escalation each need their own steps, roles, and sign-offs, and a static BPMN diagram flattens all of that into one busy canvas. And a modeling artifact is not an audit defense on its own: it lacks the owner on each step, the version history, and the attestation that an assessor will actually accept.
The division of labor
Keep Bizagi for modeling and for the low-code apps your developers build. Move the ownership of the process to a system that treats it as a living record: steps, owners, scenarios, sign-off, versions. FLOW imports BPMN and diagram exports directly, pulls the steps and roles out of the model with AI, and gives you a draft living process to approve. From there the master stays current: every change is versioned, every approval is logged, and the whole portfolio is readable over API, CLI, and MCP by your team and your agents. When something needs to execute, FLOW feeds it. It sits upstream of the runtime and keeps the standard true. See the product page for how the scenario engine works, or read what a process system of record actually is.
Side by side
| Bizagi | FLOW | |
|---|---|---|
| Primary job | Model the process, then build the app that runs it | Own the process as a living system of record |
| Design-first or execution-first | Design-then-handoff: the model feeds a built app | ✓ design-first, and feeds the tools that execute |
| Scenario routing | ✕ static BPMN plus form show/hide logic | ✓ one master resolving to the exact route |
| Governance and sign-off | App-level controls, not master-process ownership | ✓ review, approval, ownership per step |
| Audit trail | Runtime logs of the built app, not the standard | ✓ every version, comment, and approval |
| Agent-readable (API, CLI, MCP) | Model and app data, not one governed master to run | ✓ the process legible for any agent to run |
| Stays current / time to value | ✕ model drifts from the running app after handoff | ✓ regenerated from the live process, live in weeks |
| Price posture | Free Modeler; automation platform quoted by project | £36k to £180k/yr platform pricing by organization |
The verdict
A modeler answers "what does the process look like?" A low-code platform answers "can we build an app to run this one flow?" A system of record answers a different question: "is this still true, who owns it, what does it do when the situation changes, and can we prove it?" Bizagi is a strong answer to the first two, and if that is your need it is the right and capable choice. But a diagram that decouples from the running app the day after go-live is not a living record, and no amount of modeling fixes that on its own. If your processes have to stay current, route by scenario, and survive an audit, that is the moment to import the model into FLOW and keep Bizagi for the drawing and the building. The product page shows how the import works.
Common questions
Is FLOW a Bizagi alternative?
For owning the process after it is drawn, yes. Bizagi is a strong BPMN modeler and a low-code automation platform: you model the flow, then build the app that runs it. FLOW is a process system of record: one master process with owners, versions, sign-off, and scenario routing that stays the true version after the diagram is done. If your problem is that the model and the running reality keep drifting apart, that is what FLOW is for. If your problem is drawing the diagram itself, Bizagi Modeler does that well and for free.
Can I import my Bizagi BPMN diagrams into FLOW?
Yes. FLOW imports BPMN and diagram exports directly. AI pulls the steps, owners, handoffs, and decisions out of the model and gives you a draft living process to approve. The diagram is not wasted work: it becomes the first version of a governed master process, with an owner on each step and a scenario engine that resolves the route per situation. The picture you already drew becomes the record you can defend.
Does Bizagi's automation keep the process current?
Only for the part you automated. Bizagi's strength is turning a model into a running low-code app, but the moment the model hands off to execution, the diagram and the reality start to decouple. The built application runs; the model that described it goes stale, and there is no single governed master that both people and agents read as the truth. FLOW keeps the master current after the handoff: it owns the standard, tracks every version and sign-off, and feeds whatever executes.
Should I pick Bizagi instead of FLOW?
Sometimes, yes. If your immediate need is BPMN modeling with a free tool, or building a specific low-code workflow application with your own developers, Bizagi is a serious and capable choice and FLOW does not replace that. Pick FLOW when the problem is not drawing or building but owning: keeping one scenario-aware master true, governed, and audit-ready across changing situations, without a build project each time the process moves.
