Why Teams Choose PageCrawl

Visual Regression Detection

Compare screenshots of your pages over time. Catch visual regressions from CSS changes, broken images, or layout shifts that automated tests miss.

Post-Deploy Verification

Trigger checks after every deployment via webhook or API. Verify that critical pages still look and read correctly after code changes.

Third-Party Script Monitoring

Detect when third-party scripts (analytics, chat widgets, ad tags) inject unexpected content or break page layout.

AI Change Summaries

Every detected change comes with an AI summary explaining what changed. Quickly determine if a change is intentional or a bug.

Multi-Page Coverage

Monitor hundreds of pages across your site. Cover the critical user journeys, landing pages, and checkout flows that matter most.

Priority Team Alerts

Route alerts to your engineering Slack channel, PagerDuty via webhook, or email. The right people hear about it without anyone forwarding a screenshot.

Production QA Briefings for Engineering and SRE

Deploys ship at 4pm, third-party scripts inject overlays at midnight, and a CMS editor accidentally clears a homepage hero on a Saturday. PageCrawl monitors your live pages between releases and gives engineering a daily QA briefing covering visual regressions, content errors, and post-deploy verification. Critical layout breaks and broken checkout flows still page on-call directly, so users are not the ones who report them.

Fastly CDN outage took major sites offline
AI OverviewStyle: Detailed
A global Fastly CDN disruption began at 09:47 UTC and returned errors on sites including Reddit, The Guardian, the Financial Times and gov.uk. Fastly disabled the triggering configuration and 95% of its network was operating normally within 49 minutes. Fastly traced it to a bug shipped on May 12 and triggered by a valid customer configuration change. Pages served through a single CDN had no fallback.
96
Fastly published a status post at 09:58 UTC: "We're currently investigating potential impact to performance with our CDN services." Most services recovered by 11:00 UTC and the status post was resolved at 12:44 UTC.

The Guardian homepage returned 503 errors instead of content, as did Reddit, Twitch, Pinterest and the Financial Times. All of them are served through the same CDN, so the outage hit them at once.

gov.uk was unreachable during the disruption, alongside GitHub, Stack Overflow, PayPal, Shopify and Stripe. Service returned as the CDN recovered within the hour.

Fastly posted its outage summary the same day: a software deployment on May 12 introduced a bug that a customer configuration change triggered on June 8, causing 85% of its network to return errors. Detected within one minute, 95% normal within 49 minutes, permanent fix rolling out from 17:25 UTC.

How Scheduled Reports work

Built For

QA Teams

Catch visual regressions and content errors that automated test suites miss. Monitor production pages between release cycles.

DevOps & SRE

Verify deployments didn't break critical pages. Integrate with CI/CD pipelines via webhooks for automated post-deploy checks.

Web Agencies

Monitor client websites for unintended changes. Get alerted when a client's CMS update breaks the layout or removes content.

Product Managers

Track competitor product pages and your own feature pages. Know when pages change without relying on engineering to flag it.

Frequently Asked Questions

How It Works

1

Add any URL: pages, prices, numbers, PDFs, login-walled portals

Paste a competitor page, a vendor DPA, a product listing, or a government docket. PageCrawl handles JavaScript-heavy pages, cookie banners, login walls, and PDFs out of the box. Track the whole page, a specific element, a price, a stock status, or a number. The choice is yours per monitor.

2

PageCrawl detects what changed and how much it matters

For text-heavy pages, an AI summary explains in plain English what shifted and assigns a 0 to 100 importance score. For numbers, prices, and stock counts, you get the raw value, no summary needed. Pick what makes sense per monitor; AI is on tap when you want it, off when you do not.

3

Alerts only when something is actually urgent

Time-sensitive changes (price drops, restocks, new filings) hit Slack, Teams, email, Discord, Telegram, or webhook. Less urgent changes (terms updates, content drift) skip the ping and wait for the morning digest. You decide which folders and tags trigger which channels.

4

Roll the rest up into reports stakeholders actually read

Changes that do not need an alert of their own flow into AI-written digests grouped by tag, folder, or domain. Daily for ops, weekly for marketing, monthly for compliance. Each audience picks the cadence and report style (patterns, action briefing, risk assessment, or six others) that fits how they work.
