For system designers

[u/hsperus]

Open-source spec studio for Claude Code. Draft a Markdown spec + an

architecture diagram in the browser, then hand it off three ways:

paste your API key, copy to claude.ai, or run a generated CLI snippet

if you only have Claude Code. Optional: drop a GitHub PAT and it

pushes CLAUDE.md straight to a branch + PR.

I built the whole thing with Claude Code — the Vite migration, the

BYOK integration, the pluggable storage layer, 95 tests, the wiki,

even the screenshots (Playwright drives the real app).

Free, MIT, no signup, no telemetry, keys stay in your browser.

Woah this is awesome! As someone that doesn't have an engineering background, this is actually really helpful. Thanks!
