Python Web Development Sandbox

The Web Development Sandbox is a browser-based online coding environment for building Python web apps and REST APIs with Django, Django REST framework, Django Ninja, Flask, and FastAPI — no setup or installation required. Develop full-stack projects with SQLAlchemy, Django HTMX, Bootstrap, jQuery, HTML, and CSS, all pre-installed and ready to run. Spin up live development servers, build typed APIs with auto-generated docs, and preview HTML/CSS instantly in a secure, isolated sandbox. Explore and edit SQLite databases with a built-in viewer, and start from included Django and Flask sample projects. Ideal for learning Django, prototyping FastAPI backends, and practicing modern full-stack web development entirely in the browser.
