Kinto

Minimalist JSON storage service with sync, sharing, and permissions

4.4k Python Apache-2.0 today

Overview

Kinto is a lightweight Python backend providing a generic JSON storage REST API with offline synchronisation, conflict resolution, and fine-grained permissions. It is designed as a self-hostable Firebase/Sync alternative for web and mobile applications. Kinto supports PostgreSQL or in-memory backends, bucket/collection data organization, and a plugin system for auth, caching, and notifications.

Where it falls short of Dropbox

  • Focused on JSON data sync, not binary file storage or large media uploads
  • No out-of-the-box web UI for end users; requires building a frontend or using kinto-admin
  • Community activity has slowed significantly; long-term maintenance uncertain
  • Less ecosystem tooling compared to more established alternatives like PocketBase

We list the gaps honestly so you can decide if the trade-off is worth owning your data.
