We were in a similar situation a few months ago when Mitro announced that they were shutting down their service.<p>Mitro&#x27;s owner being <i>really</i> nice, they open-sourced the browser extensions, server and mobile applications so we used them to run our own: <a href="https:&#x2F;&#x2F;passopolis.com&#x2F;" rel="nofollow">https:&#x2F;&#x2F;passopolis.com&#x2F;</a><p>We plan to keep the code open-source and we&#x27;re working hard at the moment to introduce the organisation feature useful for start-ups. We plan to make the organisation feature a premium service so we can justify running and improving Passopolis for as long as it stays useful.
