Keystatic vs plain

Keystatic makes Markdown, JSON, and YAML content in a codebase editable through an admin interface or directly in files. It also supports Markdoc and MDX, with integration guides for Astro, Next.js, and Remix. Content can be stored locally, in GitHub, or in both locations, and the product is described as requiring no database. Keystatic Cloud connects to GitHub so team members can edit without individual GitHub accounts. Teams can contain multiple projects, while every user on a team can access all of them. Optional Cloud Images stores, optimizes, and delivers images for websites. Cloud Pro adds experimental real-time multi-person editing on one document. The Reader API retrieves project-directory data. A free plan allows up to three users per team with unlimited teams and projects. Cloud Pro costs $10.00 per month, plus $5.00 per month for each additional user beyond three. The project is experimental.
