Pika Suite

Beta

A private-first personal cloud: mail, calendars, contacts, tasks, notes, and files on one backend.

Pika Suite is a self-hostable personal cloud platform. One canonical backend serves first-party web and desktop clients alongside the standard protocols your existing apps already speak, so private infrastructure does not mean proprietary silos.

The problem

Leaving hosted productivity suites usually means stitching together separate servers for mail, calendars, contacts, and files, each with its own accounts and quirks. Pika Suite puts them on one canonical, self-hosted backend.

What it does

  • One canonical backend behind first-party web and desktop clients.
  • Speaks standard protocols, including IMAP, SMTP, JMAP, CalDAV, CardDAV, WebDAV, and Exchange ActiveSync, so third-party clients keep working.
  • Supports WebAuthn, scoped tokens, and per-app passwords.
  • Ships with a written security policy and private vulnerability reporting.

Security notes

  • A root security policy defines private reporting, supported-version truth, and redacted diagnostics.

Honest limitations

  • No supported public release yet; main and any alpha artifacts may change without notice.
  • The public AGPL launch is planned and explicitly gated on release-readiness evidence, including security review and signed artifacts.
  • Provider and client compatibility claims wait for dated evidence.

Where to find it

AGPL-3.0-only. A public source launch is planned and gated on a release-readiness checklist; there is no supported public release today. Progress toward publication is tracked on the developer portal.
