Detect when content on a website changes and get notified by webhook or email. Firecrawl handles fetching, diffing, judging, and notifying server-side. Each page in a check is labeled same, new, changed, removed, or error.
Pick a target mode by what you’re watching:
| Mode | Flags | Watches |
|---|---|---|
| Single page | --page <url> | one URL, for changes |
| URL batch | --scrape-urls <url,url,...> | several URLs, for changes |
| Whole site | --crawl-url <root-url> | every page a crawl discovers, for changes |
| Web search | --queries <q,...> + --goal | the whole web, for new results matching the goal |
The first three watch URLs you already have. runs your queries each check and alerts on results it hasn’t seen before (labeled once, on later checks); is required with .

Done when: create returns a monitor ID and a smoke-test run + check confirms the expected target, state, and notification configuration.
Read goals.md (opens in a new tab) when writing or refining --goal (and --queries for web monitors). Read json-tracking.md (opens in a new tab) when the user cares about specific structured fields (price, headline, stock flag) and wants per-field diffs.
update --state paused; reserve delete for monitors that are permanently done. (--state is an update flag; --status is the global CLI status flag.)--page-status changed (or new, removed, error) to skip the noise from same pages.firecrawl monitor run <id> triggers a check immediately — useful for smoke-testing a monitor right after creating it.--retention-days controls how long snapshots are kept for diffing. Lower it for high-frequency monitors to save storage.maxAge to 0 — every check performs a fresh scrape unless scrapeOptions.maxAge is set explicitly in a JSON payload.monitor when checks become recurring--crawl-url here for recurring crawl diffsAlert by webhook/email on web changes — use for "monitor/watch/track/alert me when": recurring checks on known URLs (prefer over repeated one-off scrapes) or web-wide watches for new results (queries + goal).
