Valkey vs KeyDB
Both are alternatives to Redis. Here's how they stack up — verified facts, no spin.
Also searched as KeyDB vs Valkey — same comparison, one verdict.
Valkey
TOP PICKThe Linux Foundation fork — same Redis, governance that cannot be revoked.
Valkey is the community fork of Redis taken from the last BSD-licensed release, now under Linux Foundation stewardship with AWS, Google and Oracle contributing. It is the same codebase, so the protocol, commands and clients are identical and migration is a hostname change. BSD-3-Clause, around 27k stars. The argument for it is not technical — it is that no single company can relicense it, which is precisely the event that created it. Performance has since moved ahead of Redis in several published benchmarks through multi-threaded I/O work the fork prioritised.
KeyDB
The earlier fork — multithreaded Redis, BSD, now Snap-owned.
KeyDB forked Redis before any of this to add multithreading, and was acquired by Snap in 2022. It remains BSD-3-Clause with around 12.5k stars and full Redis protocol compatibility, including active replication where multiple nodes accept writes. It is the option with the longest track record of the forks here. The honest caveat is momentum: development has slowed considerably since the acquisition, and Valkey has absorbed most of the community energy that KeyDB once held.

Valkey is Macrostack's recommended Redis alternative, so it's our pick here.
Valkey
Strengths
- +Drop-in for Redis — same protocol, same clients, hostname change
- +BSD-3-Clause under Linux Foundation governance; no vendor can relicense it
- +Backed by AWS, Google and Oracle with real engineering behind it
- +Faster than Redis on several published benchmarks after multi-threading work
Trade-offs
- −Does not include Redis Ltd's proprietary modules — no RedisJSON or RediSearch
- −Younger brand, so some managed providers still list only Redis
- −Documentation still catching up with Redis's two decades
- −Divergence from upstream Redis will grow over time
KeyDB
Strengths
- +BSD-3-Clause with a longer production history than Valkey
- +Multithreaded well before Redis addressed it
- +Active-active replication — multiple writable nodes
- +Full Redis protocol compatibility
Trade-offs
- −Development pace has slowed markedly since Snap acquired it
- −Community energy has largely moved to Valkey
- −Corporate owner rather than foundation governance
- −Fewer managed hosting options
