rustpad

Rustpad is a lightweight, open-source collaborative code editor that runs entirely in-browser with a Rust backend. It requires no database, uses WebSocket for real-time synchronization via operational transformation, and ships as a 6 MB Docker image for self-hosted deployment.

What rustpad is

Built on Warp (Rust web framework) with in-memory document storage, operational-transform algorithm for conflict resolution, and WebAssembly-compiled text operations. Frontend uses React/TypeScript with Monaco editor. Documents expire after configurable inactivity (default 24h); optional SQLite persistence via environment variable.

Quickstart

Get the rustpad source

Clone the repository and explore it locally.

terminalbash

1git clone https://github.com/ekzhang/rustpad.git2cd rustpad3# follow the project's README for install & configuration

Best use cases

Real-time collaborative coding for small teams

Ideal for pair programming, code reviews, or ephemeral collaboration sessions where documents don't need persistent storage. Low infrastructure overhead and minimal latency via WebSocket make it suitable for live coding interviews or quick team brainstorms.

Self-hosted internal collaboration tool

Deploy on private infrastructure without external dependencies. No database overhead simplifies operations, and 6 MB Docker footprint minimizes resource consumption. Good fit for organizations requiring data residency or air-gapped environments.

Educational and prototyping environments

Lightweight footprint and fast deployment make it suitable for teaching collaborative coding concepts, hackathons, or temporary dev environments where transient storage is acceptable.

Implementation considerations

Default 24-hour document expiry with no persistence requires explicit SQLite URI configuration if retention beyond restarts is needed; must provision mounted volumes for Docker deployments.
In-memory model means server capacity directly limits concurrent users and document count; no sharding or load-balancing architecture documented.
WebSocket connection stability and browser compatibility should be tested for target network conditions; operational transformation algorithm correctness depends on client-server message ordering.
No built-in authentication or access control; consider reverse proxy (nginx, Caddy) with auth middleware if multi-user or untrusted network exposure is required.
Development requires Rust, wasm-pack, and Node.js toolchain; build and test processes documented but no CI/CD templates provided beyond GitHub Actions workflow reference.

When to avoid it — and what to weigh

Need guaranteed document persistence — Default behavior loses all documents on server restart or after 24h inactivity. SQLite optional persistence requires explicit configuration and volume mounting. Not suitable if audit trails or long-term document retention are mandatory.
Require enterprise-grade security and audit compliance — No mention of authentication, authorization, encryption at rest, or audit logging in the README. In-memory storage and WebSocket architecture require careful security review before exposing to untrusted networks or sensitive code.
Scale beyond single-server deployments — Central in-memory server architecture and absence of documented clustering/federation support means multi-node deployments would require architectural redesign. Not suitable for geographically distributed teams requiring low-latency access.
Need production-grade monitoring and observability — No mention of metrics, distributed tracing, structured logging beyond env_logger, or health check endpoints. Limited visibility into server state and document lifecycle.

License & commercial use

MIT License. Permissive OSI-approved license allowing commercial use, modification, and distribution with attribution.

MIT license permits commercial deployment and modification. However, no warranty or liability limitations are clarified in the README. Recommend reviewing the LICENSE file and consulting legal counsel before deploying to production with SLA requirements or incorporating into proprietary products.

Security considerations

No authentication or authorization mechanism documented; WebSocket server is directly exposed in default configuration. In-memory storage means no encryption at rest. No mention of TLS/SSL requirements, rate limiting, DoS protections, or input validation. Operational transformation algorithm implementation (via third-party library) requires review for conflict resolution correctness. Recommend: air-gapping or reverse proxy with auth, network isolation, and code audit before exposing to untrusted users or handling sensitive code.

Alternatives to consider

Etherpad

Established collaborative editor (Node.js/JavaScript) with persistent storage, authentication plugins, and larger ecosystem. More feature-rich but heavier footprint and database dependency.

VS Code Live Share

Cloud-hosted collaboration from Microsoft. Zero self-hosting, familiar IDE, enterprise support. Trade-off: vendor lock-in, no data residency control, internet connectivity required.

Teletype (Atom plugin, archived)

Desktop IDE integration with real-time collaboration. Archived status and IDE dependency limit applicability; Rustpad's browser-based approach is more accessible.

rustpad FAQ

Will my documents persist if the server restarts?

No, by default. Rustpad stores documents in-memory. Set the SQLITE_URI environment variable to enable optional SQLite persistence to a mounted volume or file path.

Can I deploy Rustpad to Kubernetes or a managed container platform?

Yes, it's a standard Docker image. However, single-server in-memory architecture means Kubernetes scaling (multiple replicas) will not work without architectural changes; documents will not be shared across pod instances.

Is Rustpad suitable for handling sensitive or proprietary code?

Not without additional hardening. No built-in authentication, encryption at rest, or audit logging. Requires: reverse proxy with auth, network isolation, code security review, and explicit SQLite persistence configuration before use with sensitive data.

What is the typical capacity and latency?

Unknown. No benchmarks, load testing results, or documented limits provided. Performance depends on server resources, number of concurrent users, and document size; not tested or published by the maintainers.
