Mitro *

Mitro was a password manager for individuals and teams, founded in 2012 in New York City by Vijay Pandurangan, Evan Jones, and Adam Hilss (former Google/Serious Eats engineers). It let multiple people securely share and control logins to a single account, architected around cloud storage with password databases encrypted client-side using keys derived from the user master password. Mitro raised $1.2M in seed funding from Google Ventures (GV) and Matrix Partners. On July 31, 2014 the team joined Twitter and released the Mitro source code on GitHub as free software under the GPL. The hosted Mitro service shut down on October 6, 2015; its open-source successor is Passopolis. The company is defunct and publishes no live API, developer portal, or reachable domain today.

Create-or-Update Ergonomics could not be measured. We hold no machine-readable contract for this provider to read, so there is nothing to measure a write surface against. Excluded rather than scored zero: never-measured and measured-empty are different facts. Publishing an OpenAPI is what makes this facet — and several others — scorable at all.

Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. Every facet and dimension name above is a link: it opens that measurement's own page — what it means, the exact checks that feed it, how the whole catalog distributes on it, and the providers at the top of it. This rating is computed from github.com/api-evangelist/mitro: open an issue to ask a question, or submit a pull request to add artifacts.
