Looking for a free or open-source alternative to Ahrefs Site Audit? Linkguard is the closest direct swap — MIT-licensed source on GitHub, or a $24 one-time packaged install. Since you're already auditing what you pay Ahrefs Site Audit every month, here are four more pay-once tools from the same catalog worth a look while you're at it — different jobs, same idea: buy the software once instead of renting it forever.
1. Linkguard — replaces Ahrefs Site Audit
Crawl your whole site for broken links and redirect chains, with scheduled re-checks and diffs. $24 once vs Ahrefs Site Audit's $99+/mo. Free on GitHub, or the packaged installer on Whop.

Why this list is worth bookmarking
Every app above is a one-time purchase with MIT-licensed source, no accounts with us and no telemetry. None of them are trying to be the next Ahrefs Site Audit — they're trying to be the last subscription you pay for that specific job.
Try Linkguard — $24, once
Crawl your whole site for broken links and redirect chains, with scheduled re-checks and diffs.
