Fewer false alerts

Improved noise rules: rating and review counts, short ages like "3h" or "2d", announcement bars, images moving between CDN hosts, and tracking parameters inside links are now ignored.
Product-data pages are no longer mistaken for "flapping" when hidden metadata changes.
Existing baselines move to the new rules automatically, with no false alert.

New

Price mode (mode: "price"): watches a product's own price, currency and stock, never recommendations or "was" prices. Alert on drops only, set a minimum % move, or track the lowest price in a list.
Click-through actions: reach content that only appears after a click, like a fare panel.
Before/after screenshots in the Console and in email alerts, with the change highlighted.
Run output links: the Output tab now lists the changes, all checks and the run summary.

Better alerts

Screenshots highlight only what actually changed, and say so when the change isn't visible.
Pictures of JavaScript-heavy sites come from a real browser and stay current.
Pictures of GitHub pages and redirected pages render reliably and with their styling.
Alert emails read better: plain words instead of internal markers, and a readable subject.
Slack messages handle special characters; Discord messages stay within Discord's size limits.

Pricing

Lower prices: $0.002 per check, $0.004 per AI review, $0.01 per change.
Optional extras are charged only when used: screenshots, residential proxy, and pages that need a real browser.
Checks that fail because of the Actor itself are never charged.

Reliability

A site's robots.txt returning a server error is handled correctly: a site that is down is reported as down, and a site blocking bots is respected.
A run continues without a proxy if the proxy can't be set up.
The built-in AI is more reliable, with automatic backup if one part is unavailable.

1.3 — September 2026

Before/after screenshots attached to email alerts, with the changed words highlighted.
Highlights match whole words only, and skip words repeated all over the page.

1.2 — September 2026

Better comparison in html mode, including every tracking parameter in a link.
Clearer warnings when email alerts are requested but can't be sent.

1.1 — September 2026

The AI judges version numbers, removals and plan changes more accurately.
Small edits right next to a price are now always reviewed.
