Connect everything. Automate anything.

Relay is the integration layer for your product — build no-code automations, deliver webhooks reliably, and ship a developer API with OAuth2, scoped keys, and SDKs.

One platform, three building blocks

⚡
Visual automations
Compose multi-step recipes from triggers, conditions, and actions — Slack pings, HTTP calls, counters. Run history, replays, and retries built in.
🔌
Reliable webhooks
A gateway that signs every payload, retries with backoff, auto-pauses bad endpoints, and parks failures in a dead-letter queue you can replay.
🔑
Developer API
A real OAuth2 server (auth-code + PKCE), scoped API keys, versioned docs, changelogs, and generated SDKs — everything an integrator needs.
