Phase 1 / Local SaaS
Monitor your webhooks without leaving localhost.
Nerdhook is a single-purpose monitor for webhooks and small HTTP endpoints. It checks your URLs on a strict cadence, retries transient failures, and only alerts when something is truly wrong.
Built for builders: No cloud dependency, no agents, no dashboards to learn. Drop it under your web root, set intervals (5/10/30 min), and let cron handle the rest.
Signal over noise: We store the expected HTTP status per monitor, retry each check, and send a single alert when a status transitions into failure. Recoveries stay silent to reduce inbox fatigue.
Upgrade on your terms: Free covers three unique domains; PRO raises the ceiling to eight. Stripe runs in test mode only—use it to mirror how billing will work without charging a card.
Everything runs locally: PHP 8.3, MySQL, and PHPMailer SMTP. You keep the data, logs, and control.
What you get
- Email alerts on failures and recoveries.
- Retry logic with timeouts to reduce noise.
- Stripe test checkout to unlock up to 10 monitors.
- Runs entirely in Docker on localhost.
