HookWatch
HookWatch is an automated monitoring platform designed to track webhooks, cron jobs, and AI agent tool calls from a single dashboard. It provides real-time visibility into events, success rates, failures, and latency metrics to prevent silent infrastructure issues. Developers can inspect full payloads, debug delivery errors, and replay missed webhook events with one click. The platform includes cron monitoring with human-readable schedules, execution logs, and automatic retry mechanisms. Its MCP Proxy feature enables full request and response logging for AI agent tool calls without requiring code changes. HookWatch offers smart alerts through email, Slack, Discord, and PagerDuty to keep teams informed. Built for indie hackers and small teams, it delivers unified observability with a developer-friendly CLI and cloud-optional setup.

Webhooks require a lot more engineering time, resources and ongoing maintenance than you would first expect. Building a secure, reliable, and scalable webhook service is hard and time consuming. We built it so you can focus on what matters most, your business. Customer endpoints fail or hang more often than you think. You need automatic retries to ensure deliverability. You need to monitor the deliverability of your webhooks to different endpoints, disable failing ones and notify your customers. Webhooks come with a myriad of security implications, such as SSRF, replay attacks and unauthenticated webhook events. You would need to build a UI for your users to add and remove endpoints, inspect logs and get ongoing reports. Offer your users a great developer experience, including the ability to test, inspect and replay their webhooks.
