Redis code that feels like .NET

Respire is a fast, modern RESP client for .NET. It works with Redis, Valkey, KeyDB, and other RESP-compatible servers while keeping protocol details out of application code.

await using var redis = await RespireClient.ConnectAsync("redis://localhost");

await redis.SetAsync("greeting", "hello", expiry: TimeSpan.FromMinutes(5));
string? greeting = await redis.GetStringAsync("greeting");
Pre-release

Respire's public API may change. Cluster routing, Sentinel primary discovery, and bounded RESP3 client-side caching for eligible Redis reads are available; automatic Sentinel failover remains a roadmap item. See the roadmap.

Why Respire exists​

Serious Redis clients need multiplexed connections, pipelining, pooled buffers, reconnection, and careful cancellation. Application code should not need to think in protocol union types to benefit from that machinery.

Respire combines a performance-focused wire layer with an API designed for current .NET:

  • Server-assisted client caching. Eligible hot reads complete from bounded process memory; Redis invalidation pushes keep entries coherent without application-owned refresh plumbing.
  • Real return types. Commands return string?, long, bool, TimeSpan, or T?.
  • Async-first. Pub/sub, stream consumers, and key scanning use IAsyncEnumerable.
  • Discoverable commands. Data types live behind facets such as redis.Hashes and redis.Streams.
  • Automatic pipelining. Concurrent callers coalesce into fewer socket writes without a batching switch.
  • First-class blocking commands. BLPOP and blocking stream reads use dedicated pooled connections.
  • Production integrations. Dependency injection, Microsoft caching abstractions, typed serialization, and OpenTelemetry are built in.

A small, typed surface​

Common string and key operations sit on the client. Other commands are grouped by data type:

await redis.Hashes.SetAsync("user:1", "name", "Ada");
await redis.Lists.RightPushAsync("jobs", "resize:42");
await redis.SortedSets.AddAsync("leaderboard", "ada", 98.5);

await foreach (var key in redis.Keys.ScanAsync(match: "user:*"))
{
    Console.WriteLine(key);
}
