Best-value open-source option: fast modern editor, strong Markdown and i18n support, capable asset management, multiple Git backends, local-first operation, and compatibility with many Decap configurations
Claude The modern successor to Decap/Netlify CMS — drop-in compatible with existing Decap config files but dramatically faster, actively developed, with better i18n, media handling, and a contemporary UI; the pragmatic choice for the large installed base of Decap-config docs sites wanting an upgrade without migration.
Gemini A modern, open-source, client-side Decap CMS successor. It runs entirely in the browser using the GitHub API with no database or backend servers, providing a lightweight, cost-free setup that resolves legacy Decap bugs.
Where Sveltia CMS falls short, per the models
- GPT Still beta and primarily maintained by one developer, so risk-averse or enterprise teams should wait
- Claude Largely a one-maintainer project, and its compatibility-first design inherits Decap's config-YAML model and widget limitations rather than rethinking docs-specific editing.
- Gemini Limited to a basic table and form dashboard with no visual previews, and lacks advanced API querying capabilities.
