Keystatic vs Outstatic

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.

Outstatic is a Markdown-focused content management system for websites. Its editor works with Markdown and MDX files in GitHub repositories, where content is stored without a separate database or server. Content is arranged into Collections, Documents, and Singletons; Singletons can hold unique items such as a homepage or site settings. The editor lists custom fields and AI completion. The homepage names support for Docsify, VuePress, MkDocs, SvelteKit, Next.js, Hugo, Docusaurus, Nuxt, Astro, Hexo, Eleventy, VitePress, Zola, Nextra, Fumadocs, Markdoc, and Contentlayer. Outstatic supports self-hosting and a hosted PRO dashboard. GitHub login is documented through OAuth applications or GitHub Apps; PRO adds Google and email sign-in. A PRO project API key can bring AI completion, member management, added login options, automatic content setup, and a managed GitHub relay to a self-hosted instance. The free plan is free; PRO is $9.99 a month, billed $9.99/user/mo. Eligible new PRO subscriptions include a 14-day trial.
