Grevlo is a headless API for web agencies. Give us your client's URL. Get back a fully branded white-label PDF performance report covering uptime, PageSpeed, and SSL. Automatically.
5 founding partner spots — 3 months free, permanent rate lock at £99/month.
Web agencies spend 3 to 4 hours every month manually pulling uptime logs, running PageSpeed audits, and checking SSL certificates. The tools that exist were built for marketing agencies tracking ad spend, not developers proving infrastructure value.
You are either paying £300 per month for a dashboard your clients never log into, or spending Sunday afternoon copying numbers into a Word document.
There is a better way.
Upload your agency branding and connect your UptimeRobot account. Takes five minutes.
At the end of each month, POST your client's website URL to the Grevlo API. That is it.
Grevlo fetches live PageSpeed scores from Google, checks the SSL certificate, pulls uptime data from UptimeRobot, and returns a fully branded PDF report ready to send to your client. No dashboard. No login. No manual work.

AgencyAnalytics charges £300+ per month for 20 clients and still does not include native uptime monitoring.
Cheaper than one hour of a junior developer's billable time.
We are looking for 5 UK web agencies to help shape Grevlo before public launch. As a founding partner you get full API access free for 3 months, a permanent rate lock at £99 per month afterwards, and concierge onboarding — we set up your branding, build your first report template, and write your integration script. In exchange we ask for an honest testimonial, a backlink from your website, and permission to feature your logo on this page.
Email dom@grevlo.com to apply. 3 of 5 spots remaining.
We recommend UptimeRobot for uptime monitoring. Free for up to 50 monitors. Affiliate link — we earn a small commission at no cost to you.
