Built by a team that got tired of generic SEO tools.

Flatline SEO started as an internal tool. We needed a faster way to know where a website stood online, and we needed it in language a normal person could understand.

Existing audit tools either hid the important numbers behind paywalls, drowned us in 100-page PDFs, or treated every website like an enterprise e-commerce platform. None of it helped a plumber decide what to fix first.

So we built Flatline. One score. A handful of findings. Clear next steps. We use it every day. It works well enough that we opened it up to everyone else.

If you're a local business, you can run audits as often as you like for free. If you want history, alerts, and tracking across multiple sites, paid plans start at £29/mo.
