The edge-AI database for agents. Open source, embeddable, built in Europe.
| Repository | Description |
|---|---|
| barrel | The Barrel umbrella: one id over documents, blobs, and vectors. Documents, vector and BM25 search, attachments, replication, the agent layer, and the REST/MCP server |
| barrel-db.eu | The website and the Barrel documentation |
| hlc | Hybrid Logical Clock in Erlang |
| match_trie | MQTT-style topic matching trie using ETS |
The document, vector, embedding, reranking, and FAISS libraries used to live in
their own repositories. They now ship as apps of the umbrella
(apps/), and the old
repositories are archived.
