What you can build

  • Publish

    Create, schedule and track posts across networks with one request. Each network reports its own status.

  • Unified inbox

    Read and answer comments and direct messages in one model, with the reply window of each channel attached.

  • Signed webhooks

    Real-time events for new messages, comments and post status, signed, retried and replayable.

  • Built for agents

    A hosted MCP server and scoped API keys, so an AI agent can act for one customer and nothing more.

How we build it

  • Official APIs only

    Every channel runs on the platform's official API and permissions. No scraping, no shared logins.

  • Your customers stay in control

    Each account is connected by its owner through the platform's own consent screen, and can be disconnected at any time.

  • Honest delivery status

    When a platform refuses a message, you get the platform's reason, not a silent success.
