“Its been couple of years we are using Geekflare API, we like its stable production ready performance and cost-effectiveness of accessing multiple APIs through a single plan.”

Jitendra RauloDirector, Aarav Infotech

“Works like a charm, easy to use and great support. Wished they offer more features for me to use.”

Pavel MarešCEO, webtero.com

“I've been using Geekflare for both their API tools and their multi-AI chat platform. The URL-to-Markdown API has been a game changer for my content pipeline.”

Nicolas RiosHead of Product

Audit the page each country gets.

Localized sites serve different content, scripts and servers by country, and scores change with them. Add a country code and the audit runs through a proxy there.

Yes. Desktop is the default. Set device: "mobile" to audit with mobile emulation and see how scores differ.

Running it in Chrome is manual and depends on your own machine and connection. The API runs Lighthouse in the cloud, so you can automate audits across many pages in a consistent environment.

Lighthouse scores vary with network conditions, server load and the test location at the moment of the audit, so runs from different tools and places differ a little.

Yes. Run audits in the dashboard playground, use it from Zapier, Make or n8n, or let AI agents call it through our MCP server.
