Your data. Your timeline. Your control.
Stargate is a self-hosted, real-time collaboration platform that has grown beyond live sync. With built-in temporal navigation, Stargate now treats time as a first-class citizen, letting you rewind, replay, and reconstruct the entire arc of your work. It’s like version control for everything, code, notes, conversations, media, without the complexity or silos.
Whether you're a family sharing moments, a dev team iterating on ideas, or a research group preserving provenance, Stargate helps you stay in sync and in control, with full historical visibility.
Most collaboration tools treat history as a secondary feature. Stargate makes it core:
- 🗓️ GitHub-Style Activity Maps – Visualize when and how work happens
- 🕹️ Timeline Scrubbing – Glide through your project’s history like a video
- 🧭 Quantum Navigation – Step through precise changes with full fidelity
- ♻️ State Reconstruction – Instantly rebuild the state of any moment in time
All backed by a privacy-first, zero-cloud architecture that keeps your data where it belongs, on your machines, under your rules.
- Contribution Maps: Visual heatmaps of activity across days and months
- Day & Hour Navigation: Explore work at any granularity
- Event-Level Stepping: Jump backward or forward through individual changes
- Recover, Rewind, Relearn: Perfect for debugging, retrospectives, or postmortems
- WebSocket Architecture: Millisecond-latency updates with full-duplex channels
- Register-Based Collaboration: Avoid overwrites; work in parallel with clarity
- Live vs Timeline Mode: Move fluidly between active collaboration and historical review
- Fully Self-Hosted: No SaaS, no spying, no third-party lock-in
- Immutable Event Store: Append-only logs ensure auditability and integrity
- REQ Header Pattern: Secure, base64-encoded metadata in transport, no leaky URLs
- No Telemetry: Zero analytics, zero tracking, zero compromise
