elixir-horde/horde

Horde is a distributed coordination library for Erlang and Elixir that provides scalable process supervision and global state management across a cluster. It enables applications to manage dynamic supervisors and registries that automatically distribute and replicate state across multiple nodes, ensuring consistency even during network partitions or node failures. The system supports pluggable cluster transports and node selection strategies, allowing for flexible integration with different clustering backends like Partisan.

How it got here

2018 · pluggable cluster transport and distribution strategies

This period focused on introducing pluggable cluster transport and distribution strategies, allowing users to implement custom node selection logic and alternative transports like Partisan. The release also included comprehensive test coverage for these new features, added micro-benchmarks for performance evaluation, and provided a HelloWorld example to demonstrate distributed state sharing.

2019–2026 · Cluster transport and test infrastructure

The project introduced pluggable cluster transport mechanisms, supporting both standard Erlang distribution and the Partisan library for node discovery. This was accompanied by the creation of a dedicated test application and comprehensive test support modules to validate distributed supervision and registry behavior.

About this page

  • The description of this project is derived from its own commit history, not from its README.
  • The score is its highest published measurement, taken on 1 August 2026 at a pinned commit. It is not a live figure and does not change until the project is measured again.
  • Measured at commit d5c941f08d — the exact code this score is about.
  • Scored under rubric rubric-2026.08.18. Score the same commit under that rubric and you get the same number.
