Valkey · Cluster · Sentinel · BSD-3Valkey, truly open source, truly fast.
In short: Valkey is an open-source, in-memory data store and a BSD-3-licensed fork of Redis 7.2.4, hosted by the Linux Foundation and backed by AWS, Google, and Oracle. It maintains full API and protocol compatibility with Redis - supporting the same data structures, persistence, clustering, and high availability - while remaining permissively open source.
Production Valkey services across the lifecycle - deploy, migrate, operate, and support. Smooth Redis migration, cluster setup, and performance optimization. 100% Redis compatible, truly open source.

Pre-Migration Assessment
Redis → Valkey (drop-in, RESP-compatible)
Estimated cutover window: < 5 minutes
Move from Redis without the downtime
Redis 7.2 or ElastiCache Redis → Valkey 8. We assess compatibility, synchronize via replication or RDB/AOF snapshots, validate in parallel, and cut over with minimal downtime and full data integrity.

Common questions about Valkey, Redis compatibility & migration
Frequently asked questions about Valkey services and Redis-to-Valkey migration
What is Valkey and how does it differ from Redis?
Valkey is an open-source, Linux Foundation-hosted fork of Redis 7.2.4, created after Redis changed to a more restrictive license. Valkey maintains the BSD-3 license, ensuring it remains truly open source. It's fully compatible with Redis clients and protocols while being community-driven with contributions from AWS, Google, Oracle, and others.
Is Valkey fully compatible with Redis?
Yes, Valkey maintains full API compatibility with Redis. Your existing Redis clients, libraries, and applications will work with Valkey without modification. Commands, data structures, and protocols are identical, making migration smooth.
How do you migrate from Redis to Valkey?
Our migration process includes compatibility assessment, data synchronization using replication or RDB/AOF snapshots, connection string updates, parallel running validation, and cutover with minimal downtime. We ensure data integrity throughout the process.
What's the licensing difference between Valkey and Redis?
Redis moved to SSPL + RSALv2 dual-licensing which restricts cloud providers and commercial use. Valkey uses the permissive BSD-3 license, allowing free use in any context including cloud services, commercial products, and internal deployments without licensing concerns.
Can you help with Valkey cluster setup?
Yes, we specialize in Valkey Cluster deployments including shard configuration, slot distribution, replication setup, automatic failover, and cross-datacenter replication. We also configure Valkey Sentinel for high availability in non-cluster deployments.
What monitoring solutions do you recommend for Valkey?
We implement comprehensive monitoring using Prometheus, Grafana, and Valkey's built-in metrics. This includes memory usage, hit rates, replication lag, connection counts, command latency, and custom alerting for proactive issue resolution.

Compare with Other Databases
JusDB operates production fleets across most major engines. If you're weighing alternatives, here are the most common ones our customers compare against.
Redis
The upstream Valkey forked from. Useful for comparing release cadence, persistence behavior, and ecosystem maturity.
Dragonfly
Single-binary Redis-protocol KV store using a modern thread-per-core design - competitive with Valkey on multi-core throughput.
Aerospike
Larger-than-memory workloads where Valkey's RAM-bound model breaks down - Aerospike's hybrid storage handles 10×+ data volume per node.
MongoDB
Common pairing: Valkey for sub-ms cache reads, MongoDB as the document store of record for the same entities.
