Credis is a client library in plain C for communicating with Redis servers. Redis is a high performance key-value database, refer to Redis project page for more information.

Credis aims to be fast and minimalistic with respect to memory usage. It supports connections to multiple Redis servers. It runs on Linux, OS X, Windows, FreeBSD and should run on most POSIX like systems. It is released under the New BSD License.

Why

Redis seemed like what I was looking for in a social web project with high demands on scalability. Unfortunately a plain C client library was not available - until now.

Status

Current status is "almost complete". Credis implements all commands supported by Redis 1.02, almost all of 1.2.6 and most of 2.0.2. Credis is work in progress but still quite mature. The long-term commitment is to provide full support for all Redis commands. A simple credis test client is available as example and for test. Refer to credis.h for a complete list of supported commands.

For source code examples and more information see credis project wiki.

Feedback is highly appreciated. If a command is missing just drop me an e-mail or a patch. If you're using Credis it would be great to hear about.
