rserv and olu
This paints a clearer picture of the evolution of the two projects and API coverage over the last 12 months. The goal is to bring Olu to api parity with rserv 0.5.3 targeting completion sometime between March and June 2026.

Olu
Olu is a JSON document store with automatic graph relationship tracking. When documents reference each other, the graph layer maintains edges automatically. RESTful API, dual storage backends, basic graph queries. Written in Go.
https://github.com/ha1tch/olu?tab=readme-ov-file
Apart from REST queries, it features an implementation of Sulpher, a small subset of Neo4js Cypher. Comes batteries included with an in-memory LRU cache, or configurable with an external Redis cache (Docker Compose-ready, just
make docker-run)Core CRUD and graph operations work. About half the planned API is implemented. Still early but functional for prototyping.
