Contributed Systems

Smart, effective open source infrastructure for your apps


Our products are all open source-based, with a open source, free version and a commercial variant with additional features and support options.

Our first product family is Sidekiq and Sidekiq Pro. Our next products are currently under development.

About Us

Contributed Systems is based in Portland, OR and was founded by Mike Perham, a long-time open source developer. We believe that open source software is the right way to build systems; building products on top of an open source core means the software will be maintained and supported for years to come.

Contributed Systems is a play on the computer science term "distributed systems" and the fact that we allow anyone to contribute to our software.
