Redis-compatible. BSD-licensed. EUR-priced.
Valkey is the Linux Foundation fork of Redis - wire-compatible, BSD-licensed, and backed by the same maintainers who built Redis (and now by AWS + Google Cloud + Oracle). Velixir runs it as a fully managed service: backups, snapshots, optional HA, hourly EUR billing.
What you get
Concrete features, not bullet-point buzzwords.
Wire-compatible with Redis
StackExchange.Redis works unchanged. Existing Redis client code, existing CLI tools, existing dashboards - all of it just works.
RDB + AOF persistence
Durable by default at Standard and above. Hobby is intentionally ephemeral (session-store shape) so it stays cheap and fast.
Optional sync replica
Standard and above support a synchronous replica for HA. Failover is automatic; clients reconnect without intervention.
Snapshots with retention
Daily snapshots kept 7–30 days depending on tier. Restore the entire keyspace to a previous day with one click.
One-click connection to apps
Link a cache to an app and the connection string lands as REDIS_URL. No fiddling with TLS endpoints or password files.
BSD-licensed forever
Valkey is the Linux Foundation fork that exists because Redis 7.4 went source-available. No license rug-pull risk.
In your code
REDIS_URL is auto-injected when you link a cache to an app.
// StackExchange.Redis works unchanged against Valkey
using var muxer = ConnectionMultiplexer.Connect(
Environment.GetEnvironmentVariable("REDIS_URL")!);
var db = muxer.GetDatabase();
await db.StringSetAsync("session:42", "hello");
// Or with ASP.NET Core distributed cache:
services.AddStackExchangeRedisCache(o => o.Configuration = redisUrl);Pricing
Hourly EUR billing - pay only for what you use, scale up or down anytime.
All plans bill hourly. First month on us, up to €14.99 of credit - enough to run a Spark app, a Hobby database, and a Hobby cache for a full month.
What people run on Caches
- Session storage for ASP.NET
- Distributed caching with IDistributedCache
- Pub/sub messaging between services
- Rate limiting (ASP.NET Core RateLimiting + Redis backplane)
- SignalR backplane for horizontally-scaled hubs
- Job queue / locking primitives
Add Valkey to your app - costs less than a coffee per month.
Sign up takes 30 seconds. No credit card required up front - you only add a payment method when you're ready to deploy.
