Which technical SEO tool you need
Technical SEO tools split by where the crawl runs and how big a site they handle. Desktop crawlers (Screaming Frog, Sitebulb, Netpeak Spider, SEO PowerSuite’s WebSite Auditor) run on your own computer, so the limit is your machine and the licence. Cloud crawlers and enterprise platforms (JetOctopus, Lumar, Botify) crawl from their servers on a schedule, and JetOctopus adds server log analysis; Lumar and Botify do not publish prices. Suites (Semrush, Ahrefs, Moz Pro, SE Ranking, Serpstat, Ubersuggest) include a site audit capped by pages or credits a month. Free page and site tools cover a lot: Lighthouse audits one page at a time in Chrome DevTools, Google Search Console reports indexing and Core Web Vitals from Google’s own data, Bing Webmaster Tools has Site Scan, and Ahrefs Webmaster Tools audits sites you verify.
Search Console and Bing Webmaster Tools are the only tools here that report what the search engines themselves found; every crawler shows what it found, which is a strong hint, not the same thing.
How much each starting plan crawls
| Tool | Plan | What it crawls | Price |
|---|---|---|---|
| Ahrefs | Lite | 100,000 crawl credits | $129/mo |
| Moz Pro | Standard | 400,000 pages crawled a month | $99/mo |
| Screaming Frog SEO Spider | Free version | 500 URLs per crawl | Free |
| SE Ranking | Core | 250,000 pages a month in audits | $129/mo |
| Serpstat | Individual | 30,000 pages to audit | $50/mo |
| Sitebulb | Lite | 10,000 URLs per audit | $18/mo |
Allowances as each vendor words them on its pricing page, 4 November 2026. Units differ (URLs per crawl, pages a month, crawl credits), so compare them against the size of your site rather than against each other.

How this directory is built
Every price, plan, free option and trial here was read from the vendor’s own website on the date shown, and each tool links to the exact page it came from. Prices are written as the vendor showed them, in the currency it showed, with how they are billed: monthly, yearly or one-off. Some vendors show prices in a different currency depending on where you are, so check the source before you buy.
There are no ratings, rankings or paid placements, and no affiliate links. Tools are listed A to Z. Where a vendor does not publish a price, the listing says so rather than quoting a third party. Prices are rechecked every quarter; the date on each listing is the last time it was confirmed. If a listing is wrong or out of date, tell me and it will be corrected.
