fastapi vs gf
Two of the top projects in Backend and cloud templates, side by side: who leads on each score part and who each one suits, then setup, license, activity and what each review found.
fastapi
Python web framework for typed REST APIs with automatic OpenAPI docs
gf
Modular Go application framework with an HTTP server and CLI scaffolding
Verdict
fastapi ranks higher, 90 to 84. Of the 4 score parts we measure for both, fastapi leads on 2, gf on 1 and 1 is even.
- Adoptionfastapi leads by 25 points, 99 to 74: a wide gap.
- FreshnessEven at 100.
- Maintenancefastapi leads by 3 points, 100 to 97: close to even.
- Agent-readygf leads by 30 points, 30 to 0: a wide gap.
Pick fastapi if you are
Python developers building API backends, including model-serving ones
- Validates path, query, header, cookie, form and JSON body data from type hints alone
- Generates OpenAPI schema plus Swagger UI and ReDoc pages with no extra setup
Pick gf if you are
Go developers building backend services that expose APIs
- Components can be imported individually instead of adopting the full framework
- gf CLI scaffolds a project (gf init) and runs it (gf run)

fastapi
FastAPI is a Python framework for building HTTP APIs from standard type hints. It uses Starlette for the web layer and Pydantic for validation and serialization, and generates OpenAPI and JSON Schema documentation with Swagger UI at /docs and ReDoc at /redoc. It is a general-purpose framework, not an AI-specific starter.
Who it is for: Python developers building API backends, including model-serving ones
Strengths
- Validates path, query, header, cookie, form and JSON body data from type hints alone
- Generates OpenAPI schema plus Swagger UI and ReDoc pages with no extra setup
- Includes dependency injection, OAuth2/JWT, HTTP Basic auth, WebSockets and CORS
- `fastapi dev` gives auto-reload; `fastapi run` is the production command
Weaknesses
- No model, agent or other AI functionality included; you wire that in yourself
- No ORM or database layer; persistence is left to other libraries
- Relies on Starlette and Pydantic, so changes in either affect your app
- Productivity figures come from an internal team's estimates, not reproducible benchmarks
- Python
- Needs Starlette, Pydantic, Uvicorn
gf
GoFrame is a general-purpose Go framework that can be used as a full application framework or as individual components. The README shows an HTTP server (g.Server with handler binding) and a gf CLI that scaffolds and runs projects. It has no AI features and requires Go 1.25 or later.
Who it is for: Go developers building backend services that expose APIs
Strengths
- Components can be imported individually instead of adopting the full framework
- gf CLI scaffolds a project (gf init) and runs it (gf run)
- MIT license, with English and Chinese docs plus mirror sites and offline PDFs
- Recent activity: release 2026-10-28, commit 2026-11-10
Weaknesses
- No AI, model or agent integration described in the README
- Go only, and requires Go 1.25 or later
- README names no components beyond the HTTP server, so scope needs the docs site
- No Dockerfile or compose file detected in the repo
- Go
- Needs Go 1.25+
