FastAPI Integration
Built for FastAPI, but completely optional. Use it as a lightweight core for any Python application.
Fastapi Startkit
The components needs to build a great Python application.
Architected for production
The infrastructure layer for Engineers.
FastAPI Startkit is a batteries-included boilerplate for building production FastAPI applications. Modular components designed to scale with your requirements.

Core Infrastructure Modules
Modular architectural blocks designed for seamless integration into complex high-load environments.
Asynchronous Core
Fully async stack built on FastAPI, Starlette, Pydantic, and Masonite ORM — a fully async execution path for Python web applications.
Automatic OpenAPI Docs
Strict Typing Engine
Artisan CLI
Powerful artisan commands for scaffolding models, running migrations, seeding databases, and managing your application — all from the terminal.
$ python artisan db:migrate
> Running migrations...
> 3 migrations applied successfully.
AI & MCP
Build AI-native services and MCP servers on the async core. Built on top of LangChain — wire LLM providers, expose tools over the Model Context Protocol, and stream responses through the same container and provider pattern that powers the rest of your app.

System Architecture
Built for scale.
Same request path.
The Startkit is a thin, provider-driven layer over FastAPI. Every request still runs on the same Starlette and uvicorn hot path as hand-written FastAPI — the framework adds its wiring at boot, not on the request path.
Measured, not marketed
Every number here comes from the public web-frameworks harness — a reproducible benchmark you can run yourself against a raw FastAPI baseline.
Honest baseline
The baseline is raw FastAPI itself — an overhead delta, not an apples-to-oranges comparison against an unrelated stack.
Performance Benchmark
Overhead delta
Relative to raw FastAPI · uvicorn · oha · concurrency 64
GET /−2.9%
GET /user/{id}−1.5%
POST /user−17.3%
The GET routes run within a few percent of raw FastAPI. The wider POST /user gap is FastAPI 0.139's include_router resolution — reproducible in plain FastAPI, not framework per-request code.
Source: web-frameworks · relative, same-host comparison — not official benchmark figures.
