Tom's Site Auditor
Offline website health scanner - find every SEO issue, fix what matters
About Tom's Site Auditor
Tom's Site Auditor is a deliberate rejection of how the SEO tooling market works. The standard offering is a cloud platform at ninety-nine dollars a month that crawls your site from someone else's servers, stores the results in someone else's database, and keeps charging whether or not you audit anything that month. For an independent developer or a small agency auditing their own properties, that is an absurd cost structure. This tool is a Windows desktop application that runs entirely on your machine, has no accounts, no cloud component and no subscription, and costs twenty-nine dollars once.
The application detects more than thirty categories of issue, covering broken links, missing or malformed tags and the wider set of technical SEO problems that accumulate silently on any site of reasonable size. What separates it from a raw crawler is the output: every finding comes with plain-language guidance on what to actually do about it, and the report is prioritised so you fix what matters rather than working down an undifferentiated list of two hundred warnings. Version 3.0 added keyword mining, position tracking and search volume data, extending it beyond pure technical auditing. It is portable and self-contained with zero dependencies, and has passed a thousand downloads.
Download the executable and run it; there is no installer ceremony, no account creation and no dependency chain to satisfy. Point it at any website and it crawls from your own machine, which means nothing about the site you are auditing is transmitted to a third party. The scan produces a prioritised report of every issue found, each with an explanation of why it matters and what to change. Reports export as self-contained HTML files that are portable and shareable, so a client or a colleague can open one without installing anything. Deterministic mode produces repeatable scans, so two runs can be compared meaningfully, and scan history tracks how a site changes over time.
- •Fully Offline Operation - The crawl runs on your machine with no cloud component, so no data about the audited site leaves your control
- •30+ Issue Types Detected - Broken links, missing tags and the broader set of technical SEO faults, each surfaced with a priority rather than a flat list
- •Plain-Language Fix Guidance - Every finding explains what to change and why, instead of emitting a code and leaving you to research it
- •One-Time $29 Licence - No subscription, no seat count and no recurring cost, against a market where $99 per month is normal
- •Self-Contained HTML Reports - Portable, shareable report files that open anywhere with no viewer or account required
- •Deterministic Mode - Repeatable scans that produce comparable output, so changes between runs reflect the site rather than the crawler
- •Scan History - Track how a site's issues evolve across audits over time
- •Keyword Mining and Position Tracking - Version 3.0 adds keyword discovery, ranking positions and search volume data alongside the technical audit
Best suited to developers and small agencies managing anywhere from one to fifty sites who cannot justify an enterprise SEO subscription for work they do occasionally. It fits freelancers auditing client sites who want a shareable report without adding the client to a seat-based plan, and anyone working with sites where sending crawl data to a third-party cloud is undesirable. The important constraint to know before buying: this is a Windows desktop application, so macOS and Linux users are not served by it.
