What are some of the best free SEO audit tools available?

I want to do a full SEO checkup on my website to see what needs fixing. I’ve heard Ahrefs and Semrush can do this, but I don’t have them. Are there any good free tools that can scan my whole website and give me advice on what to change or improve?

I’ve tried Google Lighthouse it’s worth a try it’s simple and does technical audits pretty well
