The focused alternative to Semrush Site Audit
Semrush is a sprawling all-in-one marketing suite. If you mainly need technical SEO crawling — without a full marketing-suite price — CrawlX is a focused, cloud-native alternative with a free tier, impact-ranked issues, and fixes shipped as pull requests.
Semrush is an enormous all-in-one marketing platform — keywords, backlinks, rank tracking, ads, social and a capable Site Audit. CrawlX is not that, and doesn't try to be: it's a focused technical-SEO crawler. So this comparison is scoped to site auditing, where CrawlX is far cheaper to start, renders JavaScript on every paid plan, ranks issues by impact, and ships fixes as pull requests.
The verdict: CrawlX as a Semrush alternative
CrawlX is a focused Semrush alternative for technical SEO: it crawls in the cloud, renders JavaScript on every paid plan, ranks issues by impact, and is dramatically cheaper to start than Semrush's Guru tier. Semrush remains the pick if you want an all-in-one marketing suite — keywords, backlinks, rank tracking — wrapped around the audit.

Common questions
Is CrawlX a good Semrush alternative?
For technical SEO and site auditing, yes. Semrush is a much broader marketing suite, so CrawlX doesn't replace all of it — it's a focused crawler. Where they overlap, on site auditing, CrawlX is far cheaper to start, renders JavaScript on every paid plan, ranks issues by impact, and ships fixes as pull requests.
Is CrawlX cheaper than Semrush?
For technical crawling, yes. CrawlX starts free and then $29/month, while Semrush's entry Pro plan is $139.95/month — and JavaScript rendering requires the $249.95/month Guru plan. Semrush includes far more than crawling, though, so it's a different scope.
Does Semrush ship fixes as pull requests?
No — Semrush describes issues and suggested fixes, but doesn't open pull requests. CrawlX drafts fixes as GitHub pull requests your team can review and merge.
Does CrawlX do keyword research like Semrush?
No — keyword research and competitive analysis are Semrush strengths that CrawlX doesn't offer. CrawlX focuses on technical crawling and site auditing.
Is there a cheaper alternative to Semrush for technical SEO?
Yes. Semrush's entry Pro plan is $139.95/month and JavaScript rendering needs the $249.95/month Guru plan. CrawlX is free for 500 URLs and then $29/month, with JavaScript rendering on every paid plan. Semrush bundles far more than crawling, so it is a different scope — but for technical auditing alone, CrawlX is dramatically cheaper to start.
Is the CrawlX free tier better than Semrush's free audit?
They differ: Semrush's free account audits up to 100 pages per month, while CrawlX is free for 500 URLs per crawl with no monthly page cap on the crawl itself. CrawlX also ranks issues by estimated impact and can draft fixes as pull requests on the free tier.
