- Free tier included

DNS, TLS, and security headers monitored alongside speed.
What stays on your radar
Keep watch across every layer.
A fast page is only part of a healthy website. Follow performance, infrastructure, discoverability, and visual changes as your site evolves.
Page speed
Repeatable lab tests on a schedule, with full history.
Core Web Vitals
LCP, INP, and CLS measured against Google's thresholds.
Domain health
DNS, TLS, email authentication, and security headers.
AI readiness
llms.txt, robots rules, and structured data for AI crawlers.
Change detection
Screenshot and content diffs between one run and the next.
Fixes
From finding problems to fixing them
An audit that ends in a list of failures is homework. SpeedInts groups findings across speed, SEO, AEO, and AGEO into one prioritised plan in plain language: what to change, on which page, and what it should move.
- Prioritised by impact, not by rule ID
- Written for the person doing the work
- Re-checked against evidence on the next run
Diagnosis
Understand why the page got slower
Every test is kept, so a regression is a diff instead of a guess. Compare runs from before and after a deploy, a plugin, a tracking tag, or a CMS edit, and read the request waterfall that explains the number.
- Full test history for every page
- Request waterfall and resource timing
- Mobile and desktop results side by side
Coverage
Check every page, not just the homepage
Sites do not get slow evenly. Track pricing pages, templates, and campaign landing pages as first-class URLs, each with its own schedule, history, alerts, and reports.
- Per-page schedules and thresholds
- One site, many monitored URLs
- Trends that survive a redesign
Alerts
Catch issues before your client does
Thresholds, drops, content changes, and downtime all raise the same alert path: email and webhooks. Full-page screenshots and markdown diffs show what changed on the days the metrics look fine.
- Threshold, drop, and site-down rules
- Visual and content diffing
- Email and webhook delivery
Test a URL before you sign up
Run a focused public check and see the useful part of the report immediately.
Private by design. Quiet by default.
Monitoring should watch your site, not the people visiting it.
No scripts on your site
SpeedInts tests from the outside. Nothing to install, no tag to add, and no visitor data collected from your pages.
GDPR-aligned
Data is processed on the edge within a documented retention window, and a DPA is available for paid plans.
Alerts, not noise
You hear from SpeedInts when a threshold breaks or a page changes. Everything else waits in the dashboard.
