Health score?A 0-100 score computed nightly from four factors: maintained (40%: recent commits and steady activity), popular (25%: GitHub stars, log scale), easy to install (20%: platforms, install notes, setup guides, Docker image) and light to run (15%: minimum RAM, ARM support). When the source code has been checked, a fifth factor, security check (20%: automated scan for committed secrets, unsafe desktop-app settings, known-vulnerable dependencies and project hygiene; any serious finding caps it at 20), is added. Factors without data are left out and the rest are rescaled.

Common questions

Where are diagrams stored when using OpenFlowKit?

It uses a local-first model and the project states it has zero server-side storage.

Can I generate diagrams using a local LLM instead of a cloud AI provider?

OpenFlowKit supports 10 AI providers plus Ollama, with a localhost preset for fully offline diagramming.

What self-hosting issues are specifically mentioned for OpenFlowKit deployments?

A stability update targets config mismatch bugs and common CORS or connectivity issues in self-hosted or forked deployments.
