zerith-labs/zerithdb

ZerithDB is a platform for building web applications without a traditional backend server. Normally, when you build an app that stores data and lets multiple users interact, you need a server running somewhere in the cloud, a machine that manages the database and syncs everyone's changes. ZerithDB removes that requirement entirely. Instead, data is stored directly in the user's browser, using a built-in browser storage system called IndexedDB, and when users need to sync their data with each other, their browsers communicate directly with each other in a peer-to-peer fashion, similar to how BitTorrent works. To handle the classic problem of two people editing the same thing at the same time and conflicting, ZerithDB uses a technology called CRDTs, or Conflict-free Replicated Data Types, a mathematical approach where changes always merge cleanly without requiring a central authority to resolve conflicts. The system also includes its own authentication approach: instead of passwords or email accounts, each user gets a cryptographic key pair, similar to how cryptocurrency wallets work. You would use ZerithDB when you want to build a collaborative or offline-capable web application, think shared to-do lists, note-taking apps, or real-time collaboration tools, but don't want the cost or complexity of managing servers and cloud databases. It appeals to solo developers or small teams who want to ship a fully functional product quickly. The project is written in TypeScript and is in alpha status, meaning the API may still change. Integration packages are available for React and Python as well.
