redis-rb is a Ruby client library for Redis.
The library solves the problem of communicating with Redis servers from Ruby applications by providing a one-to-one match with Redis' command API while maintaining idiomatic Ruby conventions. Methods are named identically to Redis commands, and arguments map directly to those specified in Redis documentation, making the learning curve minimal for developers familiar with Redis. The client handles connection management across multiple scenarios: standard TCP connections, remote servers on different ports, Unix sockets, password-protected instances, and Redis ACL authentication. It negotiates the RESP3 protocol by default for more efficient data parsing, where the server tags structured replies with native types so the client receives data already shaped as Ruby objects rather than requiring post-processing. The client automatically detects servers without RESP3 support and transparently falls back to RESP2.
Developers should choose this library if they are building Ruby applications that need Redis integration and want a straightforward mapping between Redis commands and Ruby method calls. It suits any project using actively supported Ruby versions and Redis servers, as the library explicitly targets only those runtimes. The README does not compare this client to alternatives, so no comparative guidance can be offered.
The maintainers typically respond to new issues and pull requests within a day.
