Bulk TikTok ad exports charge you per row returned — including the duplicates you get when you sweep several countries, and the overlap is real (38% between US and GB). This one de-duplicates before it bills, so you pay for distinct creatives, not repeated rows.

X scrapers hand you the same timeline again on every run, and many want your login. This one needs no account at all, remembers what it already delivered, and charges only for tweets you have never seen. Baseline, repeats and errors are free.

Watches named Texas Medical Board physician licenses in the official registry, alerting only on a genuine change: registration status (revoked, suspended, cancelled), disciplinary status, or board action. For hospitals, staffing agencies, insurers, malpractice due-diligence, HR. Free when unchanged.

Companies House tools let you look a company up; none of them tells you when something lands. This one watches your list and reports only filings that appeared since your last check — accounts, charges, officer changes, insolvency notices. Official free API, quiet days cost nothing.

Beneficial ownership changes are buried in filings and nobody watches them for you. This one tracks the PSC register of your companies and reports only new persons with significant control since your last check. Official free API; quiet days cost nothing.

USAspending gives you a firehose and no way to see what is new. This one watches your agencies and reports only contract awards that appeared since your last check. Official free API, and an agency with nothing new costs you nothing.

Price scrapers hand you a quote and leave the watching to you. This one remembers the level it last alerted you at and fires only when a ticker actually moves past your threshold or breaks its 52-week high or low. A ticker that stays quiet is free.

Headless Chrome gets blocked by Cloudflare, DataDome, PerimeterX, TikTok and Meta within seconds, and captcha solvers cost $1.50-$3.00 per 1,000 requests. This browser is patched at the engine level instead: real fingerprints, no automation leaks, up to 80% less bandwidth. Pay per page.

Ads Library scrapers re-download a competitor's entire ad set every single run, so you diff it yourself and pay twice for ads you already had. This one tells you what is NEW since your last check — nothing else. Blocked and failed attempts are never billed.

Watches named Texas real estate license holders in the official TREC registry and alerts only on a genuine status change (Revoked, Suspended, Probation, Surrendered, Expired). For brokerages, HR screening, title companies, insurers, due-diligence. Free when nothing changes.

Finding UK companies incorporated yesterday means re-running the same search and diffing it by hand. This one remembers what it already delivered and reports only genuinely new incorporations matching your SIC code, name or location. Official free API; a search with nothing new is free.

Zillow scrapers snapshot a listing and forget it, so you rebuild the history yourself. This one remembers the last confirmed price, Zestimate and status per listing and bills only when something actually moved. No third-party browser account needed; blocked and failed checks are never billed.
