EventSend.

EventSend is a single HTTP endpoint an app posts events to. It records each event in a searchable feed, then delivers it to where the team already works: Slack, Discord, Telegram, push or a webhook. A payload such as {"event": "payment.failed", "message": "..."} is all it takes; the service handles validation, deduplication and retries against destinations that misbehave. Sources flip the flow around: a signed webhook URL pasted into Stripe, GitHub or Vercel turns their notifications into the same feed without any code. The product also ships an MCP server and copy-ready prompts, so an agent can instrument the moments worth knowing about and then answer questions about them.

Small teams learn about failed payments, deploys and signups from customers or dashboards instead of their own system, and building reliable fan-out with retries is infrastructure they would rather not maintain.
