Small things, finished properly.
Alongside Mitamaton we build small, complete pieces of software to test one idea at a time. Each experiment ships as a real product with its own privacy policy and support page. Each is honest about what it can and cannot do.
An experiment is not a beta of something larger. It is a finished tool with a narrow job, maintained for as long as it is useful. If one grows into a product, we will say so here. If one is retired, its pages stay up so the people who used it can still find the record.
