Auth
End-user signup, login, OTP, and sessions, with project API keys kept separate from account credentials.
GO-NATIVE · APACHE 2.0
A dependable backend foundation for your app.
Appunvs Cloud is powered by the open-source Mortar project. Auth, data, files, realtime, and usage share one explicit project-tenant boundary. Any app can use it; Fabric and Keel are not prerequisites.
Mortar is Apache-2.0 open source · self-hostable · Appunvs Cloud is open for registration

APPLICATION CAPABILITIES
Common backend jobs, each behind the right boundary.
The public app client and account/admin client use different credentials. A key safe to ship in a client bundle never gains service-role or cross-project access.
Data
Postgres table and row CRUD stays inside the project tenant boundary, reinforced by server-side RLS.
Files
One upload, download, and signed-URL API over local disk, Aliyun OSS, or Tencent COS.
Realtime
SSE row changes, broadcast, and presence without forcing a heavier client connection model.
Functions & jobs
Invoke configured function endpoints, with cron and queue exposed as separate extensions.
Usage & control
Projects, balances, usage ledgers, and tier management live in an independent control plane.
TYPESCRIPT QUICK START
Start with a familiar client API.
The TypeScript SDK is the reference implementation with the broadest coverage. The project UUID belongs in the host; there is no separate tenant option.
