Important: visual builders, code editors, and CMS platforms differ
Webstudio, Silex, Frappe Builder, Ycode, and Plasmic are visual website builders. Onlook edits React apps visually and writes changes back to your code. Grida is a design canvas and app builder, and Nordcraft is a visual web development engine. WordPress and Drupal are content management systems that need themes or builders for Framer-style design.
Closest to Framer
Webstudio is the closest open-source visual website builder, with responsive layouts, a component library, real-time collaboration, and full control of HTML and CSS. Plasmic is the closest for teams that want a visual editor that connects to data sources and produces production React code.
License details
Onlook, Grida, and Nordcraft's engine packages are Apache-2.0, Plasmic is MIT outside its platform directory, which is AGPL-3.0, and Frappe Builder and Ycode are MIT. Webstudio and Silex are AGPL-3.0, WordPress and Drupal are GPL-2.0-or-later. Nordcraft's GitHub repository only holds the engine packages used by its hosted editor, so the editor itself is not fully open source.
Hosting and pricing
Webstudio, Silex, Frappe Builder, Ycode, Plasmic, WordPress, and Drupal can be self-hosted. Ycode and Plasmic also offer managed cloud plans, and Nordcraft is a hosted product with enterprise support. Onlook runs as a desktop app and is free.
Maintenance status
Onlook's last commit was in August 2026. Webstudio, Plasmic, Frappe Builder, Silex, Grida, Ycode, WordPress, and Drupal were updated within days of this update. Ycode and Nordcraft are small projects, so check their maturity.
