one of the cofounders here, happy to answer questions. we've been building this for a while and finally hit the point where open sourcing made more sense than keeping it closed.
Hey - small Aussie team here. It's 1am and we just open sourced ContextUI.
It's a local-first desktop app for building and running visual AI workflows. TSX-based UI modules, full filesystem/CLI/GPU access, works offline with no cloud required.
Workflows can be published to the Exchange - others install and run them locally with deps resolved automatically.
Agents can create workflows and immediately test/run them in the same runtime.
Desktop app is Apache 2.0. ~300 users, ~230 workflows published.
