Anvil

Anvil is a browser-based web application builder where both front-end and back-end code are written in Python. It addresses the setup work typically involved in full-stack development by combining a visual drag-and-drop designer, a built-in Postgres-backed database, user authentication, and cloud deployment within a single framework, reducing the need to write boilerplate for database access or sign-up flows.

The platform runs as a web-based IDE and includes server-side Python execution, PDF document generation, HTTP REST API building, email sending, background tasks, file uploads, Git version control, and secure storage for sensitive information. Built-in components cover Google Maps, YouTube, and Stripe, and the environment supports installing any pip library. AI agents can be connected directly from the Anvil Editor or an external IDE. Apps can be deployed to the cloud with one click, or Anvil can be installed on-premises; the app server runtime is open source.

Anvil is aimed at developers building full-stack applications in Python. It offers a free plan for one developer account with unlimited apps, alongside paid editions (Hobby, Business, Production, Enterprise) that add features such as custom domains, collaboration, SSO, staging environments, extra compute, and private instances. Seat counts and resource limits vary by edition, and free educational licences are available for students and educators.
