The bridge stays thin

Your agent owns the conversation.

cxntion handles SMS webhooks, tunnel routing, delivery bookkeeping, and Pro-gated number activation. The model, memory, tools, policy, and personality remain in the agent you already run.

    Run the CLI

    Init, doctor, and connect from the same machine that can reach your agent endpoint.

  2. 02

    Activate a beta SMS number

    After review and Pro activation, cxntion wires Twilio SMS webhooks, A2P delivery, and the outbound tunnel.

    The agent texts back

    Every message arrives with channel, caller, timestamp, context, and a request ID.

Why us?

Why cxntion wins the boring parts.

The hard part is not forwarding one SMS webhook once. It is making delivery, routing, cost guardrails, and runtime behavior hold together cleanly every day.

  1. SMS is first-classsub-second handoff

    Texting runs through its own production path, so replies stay fast, measured, and independent from experimental channels.

  2. Bridge, not lock-inno agent patching

    Hermes, OpenClaw, or any OpenAI-compatible endpoint can stay exactly where it already runs.

  3. Costs are visible early500 segments included

    Pro is designed around SMS segment math, carrier fees, A2P costs, and soft warnings before surprises.

  4. Built for self-hostingworks behind NAT

    The tunnel is outbound, so droplets, Fly machines, Railway apps, and local servers all fit the same model.
