pycrdt-store
Persistent storage for pycrdt
Decision gist · record as of 2026-08-14
Yes, if you are building a collaborative application with pycrdt and need durable storage. The package has low install friction, active maintenance, no known vulnerabilities, and a permissive license. However, verify that its storage model and API match your persistence requirements before committing to it in production, as it is still in Beta and documentation is limited.AI-flagged interpretation of the facts on this page — verify before relying
Before you install
- Requires Python 3.10 or later; depends on pycrdt, anyio, and sqlite-anyio at runtime.
- Low install friction with a pure-Python wheel distribution.
- The package is actively maintained with a recent commit on 2026-06-11 and carries Beta status, indicating ongoing development but reasonable stability for experimental use.

What it is and what it does
pycrdt-store is a persistence layer for pycrdt, the Python implementation of Conflict-free Replicated Data Types (CRDTs). It bridges the gap between in-memory CRDT state and durable storage, allowing collaborative documents to survive process restarts and be shared across sessions. The package depends on pycrdt for the core CRDT logic, anyio for async I/O abstraction, and sqlite-anyio for SQLite integration, suggesting a file-based or database-backed storage model.
The package is in Beta development status, actively maintained, and targets modern Python versions (3.10 through 3.14). It is designed for developers building collaborative applications—real-time editors, shared workspaces, or distributed systems—who need to persist CRDT state durably. The low install friction and permissive MIT license make it straightforward to integrate into existing projects.
Use it for
- Persist collaborative document state in a real-time editor so changes survive server restarts
- Store CRDT snapshots for audit trails or version history in distributed applications
- Back up shared data structures in multi-user applications using yjs-compatible protocols
- Enable offline-first workflows by loading and saving document state between sessions
- Implement durable state for conflict-free replicated objects in backend services
