Sidekiq
Simple, efficient background jobs for Ruby
Sidekiq is a background job framework for Ruby applications that uses Redis to process jobs across multiple threads. It provides scheduled jobs, error handling, a web interface, a Ruby API, middleware, and support for long-running jobs. The open source edition is released under the LGPLv3 license, while Pro and Enterprise are commercial editions with additional functionality and support.
Sidekiq Pro adds reliability features such as job recovery after process crashes and local enqueueing during Redis outages, plus batches with callbacks, queue pausing, job expiration, Statsd metrics, Lua-based API extensions, and job search in the Web UI. Enterprise adds rate limiting, cron jobs, unique jobs, rolling restarts, historical metrics, multi-process support, encryption, and Web UI authorization. Pro and Enterprise are distributed through a private gem server and include priority email support.
Sidekiq is aimed at hobbyists, small businesses, and mid-to-large companies. The open source edition is free, Pro is available on an annual subscription, and Enterprise is priced per 100 threads with volume discounts. Purchases include a two-week money-back guarantee.
