Does SEO by Zaweba work on Mac or Linux?

Yes, SEO by Zaweba works on Mac and Linux as well as Windows. There is a separate build for macOS and Linux that uses the same engine and the same database files as the Windows version, so the checks, scores and advice behave the same way. The one practical difference is JavaScript rendering, which on a Mac or Linux PC goes through a Chrome-family browser you already have installed.

What stays the same

The engine is the part that does the work: the guided audit, the results page reader, the page checks, the site crawler, the scoring, the advice and the reports. Because it is shared, an audit gives the same findings on any of the three systems. The database files are shared too, which matters if you work across machines. Projects, scans and history are stored in the same format, so they mean the same thing wherever you open them.

The way you work is the same as well. You start a project, give it a page and a search term, bring in the results page and let the app compare you with the pages above. The six steps, the dashboard tabs and the plan that comes out at the end follow the same engine.

Rendering on Mac and Linux

On Windows, rendering pages with JavaScript uses Microsoft Edge WebView2, which comes with Windows 11. That isn't available on a Mac or on Linux, so the separate build uses an installed Chrome-family browser instead. If you want to compare the raw HTML with the rendered page there, or measure local LCP, CLS and page weight, make sure you have one installed.

If you don't need rendering for a particular site, you can still run every other check. Many small business sites deliver their content in plain HTML, and the raw HTML checks cover the title, headings, content, links, images and structured data whether rendering is on or not.

Choosing a version

Use whichever matches the computer you work on. A web designer on a Mac gets the same audit as a colleague on Windows, and the HTML report, AI Fix Brief, content briefs and CSV exports are ordinary files that open anywhere. The AI Fix Brief is markdown, so it can be handed to Claude Code or another assistant on any system.

What the audit gives you

Whatever the system, the point of the audit is a plan. The dashboard shows an overall score and a score for each of nine categories against the top-3 average. Next steps names the single most important fix first, with what, where, why, impact and effort, then three to seven more. The To-do list keeps track of them, and the next scan checks the ones you marked done. Those are the parts you'd use day to day, and they come from the shared engine.

SEO by Zaweba is free software with no account and no subscription on any platform. Install the build for your system, start a project, and the six step guided audit takes you from there.
