FuncToWeb

Turn typed Python functions into web interfaces.

Write a normal Python function with type hints. FuncToWeb turns it into a ready-to-use web form, validates its input and runs it over HTTP. No models, no duplicated schemas, no hand-written forms.

The same function is also an HTTP endpoint, a contract published at /doc for people and agents, an application you mount inside FastAPI, and a page your own frontend opens in a modal.

from func_to_web import run

def divide(a: float, b: float) -> float:
    return a / b  # Any exception becomes a clean error in the page and the API

run(divide)  # http://127.0.0.1:8000

Documentation

• Overview: one function as a form, an API, a contract and a modal; how it works.
• Getting started: run(), several functions, FastAPI, the options and the examples.
• Types and validation: what a parameter can be, and its constraints.
• Files: file parameters, uploads and how long files are kept.
• Outputs: text, tables, images and downloads.
• Prefill and OpenForm: forms that open filled in, and functions that open other forms.
• HTTP API: /invoke, streaming and /doc.
• sdk.js: calling a space and opening its forms from your own frontend.
• Security and limits: what FuncToWeb guarantees, and what is up to you.
