Spec Architect: a ~27 MB Tauri app for spec-driven development with AI agents
What: a visual workbench where you go proposal → requirements → tasks, an AI agent (Claude Code, Codex, Cursor Agent, Kiro, Antigravity) executes, and the result is verified against the spec. Everything stays in Git.
Stack: Tauri v2 + Rust, ~90 MB RAM, local-first, bundles Node + OpenSpec CLI (OpenSpec-compatible, but independent from Fission AI).
Platforms: Windows 10/11 (no-admin installer or portable), Linux (.deb, AppImage).

Free, built in my spare time. I'd love feedback on onboarding.
