I'm a marketer, not a full-time developer. Supastack brings auth, workspaces, billing, BYOK AI, email and themes together in one codebase. The AGENTS.md and prompts help me start building with Claude Code without learning every corner of the repo. Solid base for AI SaaS.
bynikojuliuspnpm verify:local, the theme packs and the block library helped me restyle my whole marketing site quickly. The kit is easy to work with.
UniverseWhile building Skin Profile, I could see how auth, billing, jobs and the AI router are configured. It feels complete.

Start buildingI'm building Lixing, a local-first reflection app. I ran the monorepo on Windows and pulled four patterns into my app: config, secure license storage, entitlements and a paywall. The port passed 26 tests behind a feature flag before touching production. I don't need auth or billing today, but I know where to look when Lixing needs a backend.
PengGangjieI'm using Supastack for my app's backend now. I wish I'd had it from the start. It would have saved me even more work.
OpenMargin24I went through the repo in depth and ran the Rust tests. Few boilerplates ship a desktop option, so Supastack feels like a dream come true. The boundaries are written down and the code honors them — the desktop app never forks the web app's UI or auth.
Raven S.I'm not a coder, but Supastack's extensive documentation has taught me so much. I'm already building a landing page for my site, cutviee.com, even though I started with zero coding knowledge. It's truly beginner-friendly.
