FROM POCKET TO PLATFORM
A new job for
an existing phone.
The project is building the connection between your application, your gateway and your mobile carrier.
A gateway you control.
An Android app connects your phone to the server, with device enrollment and a visible connection state.
An API for your workflow.
The goal is to send and receive SMS from your applications, with explicit queues, status and device controls.
Open from the start.
Read the implementation, follow the roadmap and contribute. Self-hosting instructions and development tools live with the source.
WHERE WE ARE TODAY
Release candidates.
Clear limits.
Source release candidates are for development and controlled pilot evaluation. General SMS sending and public hosted signup are not available.
Read the project documentationSource and development tools
The repository is public. You can inspect the code and contribute through issues and pull requests.
Gateway and owner dashboard
Gateway and dashboard work is under controlled testing. Owner sign-in is for existing test accounts; public onboarding is not open.
General sending, hosted plans and AI
The signed Android candidate is for restricted pilot evaluation and does not establish production readiness or carrier compatibility. Hosted plans, text receptionist and personal AI by SMS remain unavailable.
CLEAR EXPECTATIONS
Your SIM.
Your carrier's rules.
Sending SMS still requires a compatible phone, an active SIM and an appropriate carrier plan. Carrier charges, limits and acceptable-use rules apply.
Conventional SMS is not end-to-end encrypted. Carriers and recipients can read messages. Don't use the development deployment for sensitive or production messaging.
