## What it is
Holochain is an open-source Rust framework for building peer-to-peer applications that run on users' own devices without centralized servers or blockchains. It combines cryptographic signatures, distributed hash tables, and agent-centric, consensus-free data validation to create secure, scalable P2P networks.

## Use cases
- build peer-to-peer apps without servers
- develop decentralized applications without blockchain
- create agent-centric apps where users own their data
- build serverless social or collaboration apps
- run distributed apps that scale with their user base
- write P2P application DNA logic in Rust

## When to choose
- you want P2P apps with no backend hosting costs or central point of control
- you need agent-centric data integrity and user-owned identities
- you want consensus-free validation instead of blockchain overhead
- your team is comfortable with Rust for application logic

## When to avoid
- you need a battle-tested, fully hardened platform - it is still in beta undergoing security reviews
- you require traditional client-server architecture or HTTP APIs
- your team cannot work in Rust
- you need smart contracts with global consensus or token economics
