// common questions

Can I start free without a credit card?

Yes. The free plan has no time limit and no credit card required. You get 3 watches with 30-minute check intervals — enough to start catching changes immediately.

What's the difference between 30-min and 5-min checks?

Free watches are checked every 30 minutes. Pro and Business watches are checked every 5 minutes, and are prioritized ahead of free watches in the queue. The faster interval means you catch changes within minutes, not hours.

What happens to my watches if I downgrade from Pro to Free?

Your existing watches stay active. You just can't add new watches beyond the free limit of 3. On your next scheduled check, the interval will be clamped to 30 minutes.

Can I change my plan later?

Yes — upgrade or downgrade any time from the billing portal in your dashboard. Upgrades take effect immediately. Downgrades take effect at the end of your billing period.

What are webhook alerts and why would I use them?

Webhooks let Diffwatch send change alerts to any URL — your own server, Zapier, Make, n8n, or any automation tool. Pro and Business plans include signed webhook payloads so you can verify every alert came from Diffwatch. See the docs →

What's the REST API for?

The API lets you manage watches programmatically — create, pause, resume, or delete watches; pull change history; and build custom integrations. Pro includes 1 key (60 req/min); Business includes 10 keys (600 req/min). See the API docs →

How does AI change summarization work?

When a change is detected, Diffwatch runs the old and new content through an LLM to produce a plain-English summary of what actually changed — not a raw HTML diff. You get the meaning, not the noise.

Is my payment information secure?

All payments are processed by Stripe. Diffwatch never sees or stores your card details. Your billing is fully self-serve via the Stripe billing portal.
