Nobody on the wedge would pay for monitoring, near-miss tools charge $0 to $26, and false negatives destroy trust.

In their words

My own Reddit scanner reported ok on every single run because a rate limiter flipped a terminal flag on a normal response, so it was quietly reading 1 of 10 subreddits while nothing errored anywhere

reliable change detection on sites I scrape regularly, just something that notices when a target site changed its HTML structure or added a new anti-bot check and flags it before my scraper starts doing its work

We've spent significant time dealing with brittle scrapers that break silently and cause data quality issues downstream.

Product Hunt

The tools that already cover it

• Healthchecks.io: Can mark a run failed by keywords in the first 100 kB of its ping body, so a DIY check is possible; no baselines or login-wall detection.
• Sentry Crons: Catches missed or failed runs, not shrunken or login-wall output.
• ScrapeOps: Checks bans, CAPTCHAs, item quality and history; SDKs today only Scrapy and Python Requests, with Selenium, Node.js, Puppeteer, Playwright listed as upcoming. Biggest threat if it ships.
• Apify: Alerts on result-count thresholds and dataset field stats, but only for Actors and tasks run on Apify.
• Spidermon (Zyte): Scrapy only; you host it and wire up alerts yourself.
• Cronitor: Heartbeat and cron monitoring with a telemetry API and custom metrics; we could not confirm threshold alerts on job output.
• Checkly: Playwright browser checks with assertions aimed at your own site; heartbeats are listed without assertions.
• Browse AI: Monitors only its own no-code robots, not scrapers you already run; no agency features listed.
• Monte Carlo: Built for warehouses and databases, not browser run output.

How it was challenged

• The wedge is 3 people, not 40: only 3 describe silent wrong data, and the '30+ logged-in scrapers at an agency' buyer is stitched together from different commenters.
• Vendor noise: kronzap.com (twice, one counted as explicit willingness to pay), Kachilu, Citedlogic and OrderStack look like own-product posts; 5 more mentions are unrelated.
• Rivals cover parts: Healthchecks.io fails runs on output keywords, Apify alerts on low result counts, and $99 a month is 4 to 20 times peer prices.
• Window risk: ScrapeOps checks item quality and bans and lists Playwright, Puppeteer, Node.js and Selenium as upcoming; one release would close the gap for $4.95 to $19.95 a month.
• Trust problem: a 'proof report' makes every missed partial run the agency's lost client, and agencies may refuse to share logged-in client data, which blunts login-wall detection.

The pain point it solves: Constantly Breaking Scrapers

Scrapers constantly break due to site layout changes, anti-bot defenses, and schema drift, forcing costly manual maintenance.

Why those fall short

• No JA3/JA4 control, no real browser behavior, hard to version or run locally
• no CMS plugin; third-party scripts raise privacy and qualification concerns
• schema check catches changed shape, nothing when shape fine and values junk
• IP blocking useless; blocking bots removes AI referral traffic; rules need constant upkeep
• Non-deterministic output, hallucinated URLs, skipped sections; per-site trimmers a maintenance nightmare
