FastAPI vs Django vs Pyron

The bet is not RPS. FastAPI already wins “JSON API in an afternoon.” Django wins “operate the product.” Pyron is the path FastAPI leaves you to invent: HTML pages, a CLI that scaffolds them, and an admin you can turn on later — same models, same process.

Everyday job	FastAPI	Django	Pyron
POST /books + /docs	Minutes	More setup	Same as FastAPI
HTML page + form that saves	You wire Starlette + Jinja + CSRF yourself	Built in	templates= + Form() + redirect(..., message=...)
init → running app	Run an existing file	startproject (heavy)	pyron init shop && pyron dev
Edit rows without extra views	You build it	/admin	/admin when you want it
Add a public page from the panel	You write a route + template	FlatPages / CMS app	Pages in /admin (Markdown) → /p/{slug}
Shop name, phone, hours	You hardcode templates	sites / settings app	Settings in /admin; public header/footer read site
API-only for months, panel later	N/A	Hard	pyron enable admin does not rewrite handlers
SQL + Mongo + Redis	You wire it	SQL first	SQL default; Mongo documents; Redis cache

What is 2–3× easier

After pyron init shop (default template is ssr):

1. The home page has a form. Submitting it writes a row. You do not open /docs to create the first record.
2. /api/items and /admin read that same table. One Item model.
3. A flash message confirms the save. No JS.

In FastAPI that is three tutorials (Jinja, forms, admin-or-SQLAdmin) and two extra packages. In Django it is a project full of apps before “hello.”

Pyron is not a FastAPI rewrite in Rust and not a Django clone. Layers you skip (admin=False, no templates) stay out of the process.
