Our take: DiffHook suits developers and ops teams that want API and webhook-driven alerts when pages, prices or feeds change, with plans from $12 per month and a 14-day trial.

Main limitation: No permanently free plan on the pricing page, and Starter polls at best every 15 minutes with 20 monitors.

What is DiffHook, and how does it work?

DiffHook monitors public web pages, JSON APIs, sitemaps and RSS feeds on a schedule, compares snapshots and sends a change event when content differs. Optional AI alert modes cover price, availability, new items or a custom prompt. Alerts route to Slack, email, Discord, Telegram, Teams, Jira, Google Sheets or webhooks, and a REST API with signed webhooks is documented.
