description: About Rúnakefli: AGPL-3.0 license, source code, project status and links to the design document.¶

About / License¶

Rúnakefli is a single Go service that is wire-compatible with Grafana® Loki®'s HTTP API but stores and processes logs in ClickHouse®.

The name¶

Rúnakefli (ASCII: runakefli) is Old Norse for a rune stick, one of the wooden sticks medieval Scandinavians cut runes into for everyday notes; the story is on the home page. Until version 0.14.0 the project was called lokihouse; it was renamed as a precaution to avoid trademark issues with Grafana Labs' Loki mark. Rúnakefli is an independent project, not affiliated with or endorsed by Grafana Labs.

License¶

Rúnakefli is AGPL-3.0-only. The license is required because Rúnakefli imports Loki's pkg/logql/** and pkg/distributor packages, which are AGPL-3.0-only. See the full license text.

Status¶

Rúnakefli is a release candidate: it is feature complete and passes the Loki compatibility oracle. What is missing before a stable release is production experience. See the roadmap for what is still open.
