Sell tools businesses can own — not rent.
OwnOutright is the offline-first marketplace for one-time purchase business software. Build modules that run locally, keep data on-device, and respect ownership.
Why build here
- Offline-first audience with real needs
- No forced subscriptions (platform rule)
- Clear distribution + licensing handled by Core
- Updates are opt-in (no breakage)
What you ship
- Packaged module (zip)
- Manifest file (name, version, permissions)
- UI bundle + optional worker
- Local data schema (SQLite)
Marketplace rules (the moat)
These rules make OwnOutright trusted by small businesses.
No subscriptions required
One-time purchase by default. Version upgrades can be paid, but never recurring access fees.
Offline must work
Internet can be optional. Core use must function without connectivity.
No hidden data collection
Transparent permissions. No silent export of business data.
No remote kill switches
Your tools shouldn’t stop because a server is down or a policy changes.
