Co-founder (and long-time HN lurker) here.

We think that editing content for JAMstack sites can be WAY better without compromising code quality, extensibility, etc.

Most CMSs feel like a GUI on a database. We’re bringing an intuitive, contextual editing experience. Think a CMS meets Wix but developer-friendly.

How we're different:

1. Git-first. The filesystem can be a database for your content.

2. Visual editing. Your marketing team wants to see what they’re editingl.

3. Open-source and agnostic. Extend Tina with plugins. Point Tina to any API to read/write content (filesystem, GitHub API, or any 3rd party API).
