FAQ
What is OpenFlowKit and who is it for?
OpenFlowKit is a free, open-source AI diagram engine that converts text into diagrams with Mermaid.js and Figma export support. It is designed for developers, technical writers, product teams, and anyone who needs programmable, versionable diagrams integrated into their workflows.
Is OpenFlowKit really free and open-source?
Yes. OpenFlowKit is completely free to use and released as open-source software, so you can inspect the code, self-host it, and extend it to fit your own tools and infrastructure.
How does OpenFlowKit integrate with existing workflows?
OpenFlowKit supports Mermaid.js, vector export to Figma, and can be embedded into documentation sites, internal tools, or CI/CD pipelines. You can call it from your own apps or scripts to generate and update diagrams automatically.
Do I need design skills to use OpenFlowKit?
No. OpenFlowKit focuses on structure and clarity, generating clean diagrams from text so you don’t need to manually design shapes or layouts. Designers can later refine visuals in Figma if needed.
Can I run OpenFlowKit on-premises for security reasons?
Yes. Since OpenFlowKit is open-source, you can self-host it within your own infrastructure to keep code, diagrams, and sensitive documentation under your control.
