Change detection, described rather than diffed.
Diffing HTML tells you a timestamp changed. What you wanted to know was that the price moved, and diffing can't tell those apart.
- No credit card required
- Free plan to start
Why diffing disappoints
- Every page changes constantly in ways nobody cares about.
- Filtering the noise means writing selectors again.
- The signal you want is semantic, not textual.
- Alert fatigue kills the monitor within a month.
How Browza watches
Meaningful change only
Say what matters and the run reports whether that changed, not whether the DOM did.
Structured, so it's routable
Results conform to your schema, which makes alerting a normal piece of code.
Whatever cadence you need
Hourly to weekly, as a schedule rather than infrastructure.
With the evidence
The screenshot from the run that flagged it is retained.
How you'd call it
A goal and a schema over HTTP — no selectors to maintain and no browser fleet to run.
“Schedule a run that checks these pages and returns {changed: boolean, what: string} describing any change to price or availability.”
Questions people ask
How does it know what's meaningful?
You describe it in the task. That description is the filter, and it can be as specific as you like.
Does it remember previous runs?
An agent keeps its own run history, so comparisons across runs are available to it.
Can it watch pages that need a login?
Yes, using a saved profile.

What will you hand over?
Start with one task. Watch it run, take the wheel whenever you want, and keep the ones that earn their place.
