Webstudio is an open-source (AGPL-3.0) visual website builder: full CSS control, connects to any headless CMS or backend (Supabase, Sanity, Hygraph), no hosting lock-in, positioned as an open alternative to Webflow and Framer.
Hobby (free): 5 custom domains, 2GB storage, 10,000 monthly page views, 300 form submissions, unlimited sites/pages/collaborators. Pro $20/month: 20GB storage, 100,000 page views, unlimited form submissions and custom domains, CMS integrations. Pro Lifetime option also available.
Developers and designers who want Webflow-like visual building but need to avoid vendor lock-in: self-host, connect any backend, and keep full CSS control.
Being open source under AGPL-3.0 means self-hosting is genuinely possible, not merely a marketing claim, worth it specifically for teams with a hard requirement to avoid platform lock-in.
Open source Webflow alternative for the open web.
