Compression Monitoring for Brotli & Gzip
Confirm your server compresses every page and asset with Brotli or Gzip, verify the Content-Encoding header, and measure exactly how many bytes you're saving. Catch misconfigured servers, CDNs that strip encoding, and assets shipped uncompressed before they slow your site and inflate your bandwidth bill.
Comprehensive Compression Monitoring Features
Everything you need to keep responses small and fast
Content-Encoding Verification
We request your URLs with compression enabled and confirm the response actually comes back with a valid Brotli or Gzip Content-Encoding header.
Compression Ratio
Measure the ratio of compressed to uncompressed size on every check so you can see how effectively each page and asset is being squeezed.
Bytes Saved Reporting
See exactly how many bytes compression strips from each response versus the raw payload, turning bandwidth savings into a number you can track.
Brotli & Gzip Support
Check for modern Brotli or classic Gzip, and confirm your server negotiates the best encoding the client advertises in its Accept-Encoding request.
Smart Alerting
Get notified within seconds when compression disappears, breaks, or regresses below your threshold, via email, Slack, Discord, and webhooks.
Global Checks
Run checks from multiple regions worldwide so you catch CDN nodes or edge configurations that quietly serve uncompressed responses in some locations.
Historical Trends
Review compression ratio and response size over time with clear graphs, perfect for spotting slow regressions after a deploy or CDN change.
Flexible Scheduling
Set check intervals from 30 seconds to 24 hours and configure maintenance windows so planned work never triggers false compression alerts.
Why Choose Our Compression Monitoring Solution?
Compression is one of the cheapest, highest-impact wins for web performance — but it fails silently. A misconfigured server, a CDN that strips encoding, or a new asset shipped raw can bloat every response without throwing a single error. Our compression monitoring requests your pages exactly the way a browser would, confirms the encoding, and measures the savings, so you always know your responses are as small as they should be.
Verify Brotli or Gzip on any public page or asset
Confirm the Content-Encoding header on every check
Measure compression ratio and bytes saved
Catch CDNs and proxies that strip encoding
Multi-region checks to spot edge inconsistencies
Historical response-size and ratio reports
Configurable thresholds and check intervals
Instant notifications via email, Slack, Discord, and more
How Compression Monitoring Works
Simple setup, measurable bandwidth savings
Add Your URL
Enter the page or asset URL you want to check and pick the regions you want to test compression from.
Set Thresholds
Choose the encodings you expect and the minimum compression ratio that should hold before an alert fires.
Monitor 24/7
We request the URL with compression enabled, read the Content-Encoding header, and measure the compressed and uncompressed sizes on every check.
Get Instant Alerts
When compression vanishes or drops below your threshold, you get immediate notifications and a detailed incident timeline to act on.
Compression Monitoring Use Cases
Perfect for any site that cares about speed and bandwidth
Guard Page Speed
Uncompressed HTML, CSS, and JavaScript directly slow page loads and hurt Core Web Vitals. Continuous compression checks make sure your largest text-based assets always ship small and fast.
Verify CDN Configuration
CDNs and reverse proxies sometimes strip or fail to apply compression at the edge. Monitor from multiple regions to confirm every node serves Brotli or Gzip the way your origin intended.
Catch Deploy Regressions
A new build, framework upgrade, or server tweak can silently disable compression on some routes. Get alerted the moment a deploy starts shipping bloated, uncompressed responses.
Control Bandwidth Costs
Every uncompressed byte is bandwidth you pay for and your users wait on. Track bytes saved over time to prove the value of compression and catch waste before it adds up.
