Otto is now OttoFMS!
Otto v3 is no longer for sale, and support for it ended on July 31, 2025. If you are still running Otto v3, you should upgrade to OttoFMS — it is free, actively developed, and the version we support going forward. The Otto v3 documentation will remain here for reference.

Otto is brought to you by Proof. We are developers, programmers, analysts, and writers who work together to create great products, solutions, and experiences. We’re also thinkers, builders, artists, athletes, volunteers, photographers, gardeners, chefs, parents, farmers, utopian-seekers, and hard workers. At Proof, we believe technology should free up space for people to think, solve, and create. We build tools to help do just that.
