# AgentLaunch

> Ship your AI SaaS in days. FastAPI + Next.js with token billing built in.

AgentLaunch is a production-grade, full-stack AI SaaS boilerplate decoupling high-throughput Python machine learning runtimes from consumer-grade Next.js 15 web applications. It bridges Python AI tooling (LangChain, DSPy, PyTorch, pgvector) with modern React web development, automated Stripe metered usage billing, and zero-trust Supabase authentication.

## Core Architecture & Stack

- **Backend Runtime**: Python 3.12+, FastAPI, Pydantic v2, managed via uv package manager with multi-stage Dockerfiles.
- **Frontend Framework**: Next.js 15 (App Router, React 19, Server Actions, TypeScript), Tailwind CSS, Framer Motion.
- **Database & Vector Storage**: PostgreSQL 16 with pgvector extension, HNSW cosine distance indexing (1536 dimensions), and Postgres Row-Level Security (RLS) tenant isolation.
- **Real-Time Streaming**: Native Server-Sent Events (SSE) streaming (`text/event-stream`) yielding token chunks with minimal Time-to-First-Token (TTFT).
- **Usage-Based Monetization**: Automated token calculation during SSE streaming generator, with guaranteed reporting to the Stripe Meter Events API (`POST /v1/billing/meter_events`) inside a `try...finally` block.
- **Zero-Trust Security**: Cryptographic Supabase JWT verification inside FastAPI `Depends(get_current_user)` extracting verified `auth.uid()` and querying database for `stripe_customer_id` without trusting client-side metadata.
