µTask is an automation engine built for the cloud. It is:

simple to operate: only a postgres DB is required
secure: all data is encrypted, only visible to authorized users
extensible: you can develop custom actions in golang

µTask allows you to model business processes in a declarative yaml format. Describe a set of inputs and a graph of actions and their inter-dependencies: µTask will asynchronously handle the execution of each action, working its way around transient errors and keeping a trace of all intermediary states until completion.
