Linux Foundation fork after Redis license change. Gain: BSD open source, AWS/GCP backing, ElastiCache support. Trade-off: stuck at Redis 7.2 compatibility, no Redis 8 features.

AWS managed caching. Gain: Valkey or Redis 7.2, AWS integration, reserved pricing. Trade-off: no Redis 8+, Valkey lacks some features, VPC-only networking.

Serverless Redis alternative with free tier. Gain: pay-per-request pricing, scales to zero, global replication. Trade-off: different billing model, REST API adds latency vs direct connection.

Redis-compatible with better memory efficiency. Gain: claims 25x throughput, lower memory use, drop-in Redis replacement. Trade-off: newer project, smaller ecosystem.

Multi-threaded Redis fork. Gain: better multi-core performance, active-active replication, BSD license. Trade-off: less commercial support, smaller community.
