Palpo is a next-generation Matrix homeserver implementation written in Rust, designed for high performance, scalability, and robust federation. Built on the Salvo web framework and PostgreSQL database, Palpo delivers enterprise-grade real-time messaging and collaboration while maintaining minimal operational overhead.

Matrix is an open standard for decentralized, real-time communication. It enables:

• End-to-end encrypted messaging - Secure conversations by default
• Federated architecture - No single point of control or failure
• Interoperability - Bridge with other chat platforms (Slack, Discord, IRC, etc.)
• VoIP and Video Calling - Built-in support for voice and video
• Rich messaging - Reactions, threads, file sharing, and more

• PostgreSQL backend for reliable data persistence and ACID compliance
• Optimized for low latency and high concurrency

• Clean, modular codebase
• Well-documented APIs
• Docker-ready deployment

• Minimal memory footprint compared to reference implementations
• Efficient database query patterns
• Smart caching strategies
• Scales horizontally

⚠️ IMPORTANT: Test Server Notice

Our test server is for evaluation and testing purposes only:

• URL: https://test.palpo.im
• ⚠️ All data on this server will be periodically deleted without notice
• Do NOT use for production or store important conversations
• Expected to be reset frequently for testing purposes

1. Open Cinny
2. Click "Edit" on the homeserver selection
3. Enter https://test.palpo.im as your custom homeserver
4. Create a test account and start chatting!

1. Download Element
2. On login screen, click "Edit" next to the homeserver
3. Enter https://test.palpo.im
