Stop rebuilding. Start shipping.
Auth. API. RAG. Deployment. One repo. The stack you'd build yourself — packaged and maintained.
Features
Prototype with v0, scale with us.
Production-ready Auth
JWT-based authentication with FastAPI middleware. No more 'Authentication Failed' loops or fragile mock auth.
RAG & Vector DB
Built-in integration with Qdrant/Chroma and persistent storage that doesn't wipe during deployments.
V0/Bolt.new Engine
Drop your v0 frontend exports directly into our production backend. We handle the heavy lifting while you focus on the UI.
Scaling Architecture
Multi-stage Docker builds, Redis caching, and Railway deployment config. The infrastructure decisions that cost three rewrites when you get them wrong — made upfront, so you don't.
Products
Tools that ship.
LangChain + FastAPI Starter Kit
Stop rebuilding the same infrastructure. This one's already tested.
What's inside
- →LangChain 0.3+ RAG pipeline — ChromaDB, ingestion, retrieval
- →JWT auth — access + refresh tokens, bcrypt, FastAPI middleware
- →SSE streaming — real-time token output, no WebSocket
- →Redis — rate limiting, session caching, queuing
- →Docker + Railway — multi-stage build, one-command deploy
What you skip building
- ×Auth token refresh logic
- ×RAG chunking config that actually retrieves correctly
- ×Deployment setup that breaks on env vars
Uses LangChain LCEL + ChromaDB. The guide references LangGraph + pgvector — same patterns, different primitives, fully swappable.
Free Guide
The Agentic Stack 2026
The infrastructure decisions that separate AI demos from products that survive real users. LangGraph, MCP, Agentic RAG, OTel, and the Sovereignty Stack. 5 chapters. No fluff.
About
We build tools that save
developers weeks of work.
Every product we ship is something we needed ourselves — battle-tested, well-documented, and ready for production. We skip the fluff and focus on the boilerplate that actually takes time to build right.
Supertute ships production-ready AI infrastructure to indie developers — so they can focus on their actual product instead of rebuilding the same boilerplate for the hundredth time.
