Archform runs on your own machine — the client starts it, so there is no endpoint to ping. 41 installs a week from npm. Last commit 20 Oct 2026.
Render and validate diagrams as code: Mermaid, PlantUML, C4, Graphviz, D2 and more.
Today is the operative word: we check Archform every 15 minutes and re-read its code on every release. Watch it and you find out the day that stops being true.
