Instatic: open-source alternative to Webflow, Framer

About Instatic

Instatic is a self-hosted content management system with a visual editor, content engine and publisher all running in a single Bun server. It is presented as an open-source alternative to Webflow, Framer and WordPress, and aims to replace the usual pile of separate services for CMS, framework, hosting, forms and analytics.

One server holds the canvas editor, content engine, media, authentication, forms, plugins and the publisher, with users, roles and a database included, backed by SQLite or Postgres. Pages it generates are plain semantic HTML with compact CSS, without framework runtime or builder attributes, so they behave like static files. The README suggests one-click deployment on Railway, with options for Render and Docker or a VPS with Caddy TLS.

Instatic is MIT licensed and very new: the repository was created in April 2026 and the latest release is v0.0.20, so expect rapid change. It targets developers, designers and small businesses who want to own their site stack and keep the published output lean.
