What Nitro is
Nitro is a suite of Python tools for building static websites, with pages defined as Python functions. It targets developers who want to create websites in Python from start to finish. Nitro CLI provides live reload, incremental builds, dynamic routes, image optimization, draft pages, and an islands architecture. Nitro UI generates HTML through Python classes and supports type hints, reusable components, HTMX, forms, and CSS helpers. Additional tools cover JSON data access, plugins, data validation, and image processing. Nitro UI works with FastAPI, Django, Flask, or standalone scripts. CLI deployment targets include Netlify, Vercel, and Cloudflare Pages, while generated files can also be uploaded to S3 or your own server. Nitro CLI requires Python 3.9 or later; Nitro UI supports Python 3.8 or later. Nitro is free and open source, with no accounts or telemetry. Packages use BSD 3-Clause or MIT licenses. Nitro DataStore includes path traversal protection and file-size limits.
