Principles

How we pick our tools

  • Widely used and well backed

    Tools backed by big communities, so people to maintain your software are easy to find.

  • Kept in your own accounts

    Servers, domains and app store listings are held in your name, not ours.

  • Data you can move

    Standard databases and exports mean your records are never locked in.

  • Secure from the start

    Encryption, least-privilege access, backups and audit logs from the first day.

Tell us what you'd like built.
