The difference that matters is not the feature list — it is where your integrations run and what you are left holding. Boomi executes them on the Boomi Atom — a cloud-connected runtime you install but do not control. FlowSetu generates a standard Spring Boot Maven project you compile, deploy and own, with nothing of ours in the running system.
Large organisations that want a governed, vendor-managed integration platform and have the budget for it. If that describes your team, Boomi is a reasonable answer and this page is not trying to talk you out of it.
The Atom still phones home, so "self-hosted" does not mean independent — and the integrations themselves are not portable artefacts you can read or move.
No. Boomi integrations run on the Atom runtime, which is tied to the Boomi platform. A FlowSetu export is a standard Spring Boot JAR with no runtime dependency, so it runs wherever a JVM runs.
The models differ more than the prices. Boomi is an enterprise contract covering the platform and runtime; FlowSetu charges for the design tooling and generates code you run on infrastructure you already pay for. There is no runtime licence to renew.
There is no automated Boomi importer — the migration studio covers Mule 3 and Mule 4. Boomi processes are rebuilt on the FlowSetu canvas, which is usually quick for straightforward processes and a real project for large estates.
