Pre-release
This release is a pre-release and may not be stable for production use.
RustAPI
FastAPI-style Python Web Framework backed by a Rust (Tokio / Hyper) Engine — with embedded Rust Database Streaming, JWT & Argon2 Primitives, Tier 3 Rust-Native Routes, and a built-in MCP Server.
📦 Key Open-Source Features Included
| Feature Area | Implementation Details |
|---|---|
| FastAPI Compatibility | FastAPI & Request aliases, status codes, declared status_code (e.g. 201, 204), async/sync response_model with response_model_exclude/include, structured 422 validation error handling, FastAPI(lifespan=...) ASGI context managers, Depends(..., scope="function"), EventSourceResponse (SSE), jsonable_encoder, Query/Body/Path/Form/File, OAuth2PasswordBearer, HTTPBearer, APIKeyHeader, OpenIdConnect, get_openapi, app.frontend(). |
| HTTP & Routing | FastAPI-style @app.get, @app.post, APIRouter, Depends, app.dependency_overrides, response_model, reload=True. |
| Rust-Native Tier 3 Routes | app.add_native_route() zero-GIL C-speed fast-paths (50,000+ req/sec). |
| Database Engine | sqlx SQLite & PostgreSQL pool (app.connect_db()) with zero-copy JSON streaming (db.query_json()). |
| Power Primitives | Native Rust encode_jwt() / decode_jwt(), Argon2 hash_password() / verify_password(), MiniJinja render_template(). |
| Response Classes | HTMLResponse, JSONResponse, PlainTextResponse, RedirectResponse, StreamingResponse, EventSourceResponse. |
| Request Ergonomics | req.json(), req.form, req.body, UploadFile, WebSocket. |
| AI / MCP Integration | Embedded Model Context Protocol server (@app.tool(), @app.resource(), @app.prompt()) at POST /mcp. |
| Telemetry & Observability | Terminal access logging (INFO: 127.0.0.1 - "GET /render HTTP/1.1" 200 - 0.45ms), Swagger UI (/docs), OpenAPI (/openapi.json). |
⚡ Framework Standing & Multi-Framework Benchmarks
rustapi delivers 100% FastAPI developer experience (DX) while running on a high-performance Rust (Tokio/Hyper) core engine.

🏛️ The 3-Tier Execution Model
- Tier 1 (FastAPI Drop-in): Standard Python
@app.get(),async def, Pydantic models, and dependencies. - Tier 2 (Hybrid Rust Acceleration): Standard Python handlers utilizing native Rust power primitives (
db.query_json()SQLite/PostgreSQL streaming,rustapi.encode_jwt(),rustapi.hash_password(), MiniJinja templates). - Tier 3 (Pure Rust Native Fast-Path): Zero-GIL C-speed routes registered with
app.add_native_route("/health", ...)clocking 96,000+ req/sec at 0.57ms p95 latency.
