GUN is an open-source decentralized graph database protocol and JavaScript library for syncing data peer-to-peer in realtime, with offline-first support and end-to-end encryption. It serves as an open-source alternative to Firebase, enabling community-run and encrypted applications.

Use cases

• sync data between browsers in realtime without a server
• build an offline-first app that works without internet
• store user data end-to-end encrypted in a decentralized app
• replace Firebase with an open-source p2p backend
• build a multiplayer collaborative app with CRDT conflict resolution
• create a decentralized chat or social app
• sync graph data across peers with no central database

When to choose

• you need realtime p2p data sync with offline support
• you want end-to-end encrypted user data without a trusted server
• you're building decentralized/local-first web or mobile apps
• you want a Firebase-like API but self-hosted or serverless

When to avoid

• you need strong relational queries, joins, or SQL
• you require strict ACID transactions across entities
• you need a battle-tested license for enterprise compliance (license is non-standard)
• your app depends on centralized analytics or heavy server-side aggregation
