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.
Ka-Chun-MaI'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.

I built and shipped SpinShare, a Windows app for offline file conversion, with Supastack in 48 hours.

In 2024, I thought I could build something big. I launched a teacher-rating platform, and ended up getting a call from my director. That project is now closed, but I haven’t stopped shipping.
Over the past two years, I’ve tried dozens of projects: an AI image tool, an AI gateway, an AI learning app. Today, I’m still building LearnX, and I have plenty more ideas I want to try.
But every new idea came with the same first week: wiring up login, payments, emails, a database, and deployment. Before I could build the part I was excited about, I was rebuilding the same foundation.
So I built Supastack for myself: a boilerplate I could reuse whenever I wanted to start something new. Set up the foundation once, then spend my time on the idea.
Then I realized I couldn’t be the only one stuck doing this. If it helped me spend more time building, maybe it could help you too. That’s why I’m sharing it.
I’m still shipping. I just want the next idea to start with the idea, directly.

Yes. Choose Next.js or TanStack Start for web, Expo for iOS and Android, or Tauri for desktop. Buy the platforms you need, or get all four together in the Full Bundle.
Sign-in is already built. Customers can receive a code or sign-in link by email, or use accounts such as Google and GitHub. Connect the sign-in services you want to offer.
Yes. AI chat, saved conversations, usage tracking and spending limits are included. Connect your chosen AI service; you can also let customers use their own AI accounts.
