How Audra compares to other site audit tools

Audra is a $19 one-time-purchase desktop app for macOS and Windows that crawls a site locally and scores it; every tool below does something it does not. These comparisons state plainly where the other tool wins, because a comparison that never recommends the competitor is not a comparison.

• Audra as a Screaming Frog alternative Screaming Frog is a deep technical crawler on an annual licence. Audra is a one-time-purchase Mac auditor that scores a whole site. Honest comparison.
• Audra as a Sitebulb alternative Sitebulb is a subscription desktop auditor with deep prioritised hints. Audra is a one-time-purchase desktop app for macOS and Windows with an AI-visibility layer. Compared honestly.
• Running Lighthouse across an entire website Lighthouse and PageSpeed Insights audit one URL at a time. Here are the four real ways to get Lighthouse scores for every page of a site, compared.
• Audra as an Ahrefs Site Audit alternative Ahrefs Site Audit is one cloud module of a large SEO suite. Audra is a focused local auditor for $19 once. What each does, and where Ahrefs is unbeatable.
• Audra as a Semrush Site Audit alternative Semrush bundles site auditing into a broad marketing suite on subscription. Audra is a single-purpose local auditor for $19 once. An honest comparison.

Which website audit tool should you actually choose?

Choose on the job you do most weeks, not on price. If you need backlink or keyword data, buy a suite; if you need crawl scale or custom extraction, buy a crawler; if you audit one page occasionally, use Chrome DevTools and buy nothing at all.

The five tools compared here fall into three genuinely different categories, and mixing them up is the most common way to buy the wrong one. Screaming Frog and Sitebulb are desktop crawlers, like Audra — they run on your machine and keep data local. Ahrefs and Semrush are cloud SEO suites where site auditing is one module among many. Lighthouse is a free single-page diagnostic that everything else, Audra included, ultimately reports numbers from.

Audra sits deliberately at the small end: a fixed check list, a 100-page default crawl, one scored report, and no subscription. That is the right shape for a specific job — auditing small and mid-size sites and handing someone a document — and the wrong shape for almost everything else.

Which of these tools keep your data local?

Audra, Screaming Frog and Sitebulb Desktop all crawl from your own machine and store results on your own disk. Ahrefs, Semrush, Sitebulb Cloud and PageSpeed Insights all crawl from vendor infrastructure and retain the results there.

This line runs between products, not between vendors — Sitebulb sells both a local desktop app and a cloud product, so the answer for "Sitebulb" depends on which one you bought. It is worth being precise about, because plenty of comparison pages flatten it into a vendor-level claim that is simply wrong.

Where Audra differs from the other local tools is narrower than a privacy claim: it also sends no telemetry and makes no AI or LLM API calls, and after licence activation it works with no network connection at all. Against a cloud auditor that is a meaningful difference; against Screaming Frog it is a marginal one, and pretending otherwise would be dishonest.

What does every comparison here have in common?

Each page ends with an explicit "where the other tool wins" section, and each one names cases where you should not buy Audra. That is deliberate.

The reason is practical rather than noble. A comparison written by a vendor is worth reading only if it tells you when to buy something else — so each page below lists the competitor's genuine strengths in concrete terms: crawl ceilings, index sizes, features Audra does not have, and the free tiers that may make buying anything unnecessary.

Competitor pricing on every page was checked against each vendor's own pricing page in July 2026 and is dated in the copy. Where a figure could not be confirmed, the page describes the pricing model rather than inventing a number.
