🏂 EJDB2 — Embeddable JSON Database engine C library. Simple XPath like query language (JQL).

An Embedded Implementation of Redis

Multipurpose C library and persistent key/value storage

Redis adapted to use Persistent Memory

LevelCache is an ephemeral embedded cache with TTL support built on top of LevelDB.

A high-performance back-end service framework written in C.

LSM tree to the rescue

db["key"]="value" with tea encryption

Splinter is a minimalist, high-speed, lock-free message bus and pub/sub KV store that uses shared memory (memfd) or, optional memory-mapped files for persistent backing. Designed specifically for local LLM workloads and their sanitation needs, but versatile and scales to tens of millions of operations / sec.

FPGA-based accelerator for compactions in LSM-tree based KV stores. Making compaction great again, again!

A single-file, in-memory key-value store written in C with persistence, undo/redo support, and memory statistics. Ideal for small projects or scripts that need a fast, lightweight database.
