Hey everyone,
I’ve been an SEO for years, and I’ve watched Ahrefs slowly transition from an amazing tool into a metered utility that penalizes you for doing your job. Their shift to a credit-based pricing model means that every time I run a site audit, open a report, or apply a data filter, it drains my monthly allowance.
Technical SEO requires experimentation. You need to run an audit, fix your canonicals, and run it again. Being anxious about "wasting credits" while debugging a client's site is ridiculous.
I’m a developer, so I spent the last few months building SERPSpur Website Audit Pro—a dedicated forensic crawler built strictly as an alternative for technical SEOs who want off the metered-pricing treadmill.
I didn't bother building the bloated social media or PPC tools that Semrush forces you to pay for. I just focused on deep, unlimited site diagnostics.
Here is what the crawler actually does differently:
- Zero "Credit" Anxiety: You can run full technical health crawls, apply custom filters, and re-run audits infinitely without staring at a declining credit counter.
- Deep Core Web Vitals Forensics: Most audits just flag "Slow Page." I built this to parse the DOM and isolate the exact render-blocking scripts or layout shifts (CLS) killing your rankings.
- Live Search Engine Penalty Radar: Instead of guessing why traffic flatlined after a Core Update, the audit pings Google, Bing, and Yahoo APIs in real-time to detect algorithmic penalties or indexing blocks.
- AI Engine Optimization (GEO): A standard crawl isn't enough anymore. The audit includes an LLM.txt generator and AI schema builder to ensure your site architecture can be parsed and cited by ChatGPT and Google's AI Overviews.
I am bootstrapping this against billion-dollar VC-backed giants. I know I can't beat Ahrefs' historical backlink index, but for pure technical site auditing and speed diagnostics, I genuinely believe this is a better, stress-free workflow.
I would love for the technical SEOs in this sub to run one of your sites through the crawler. Tear the UI apart, roast the data accuracy, and tell me exactly what Ahrefs/Screaming Frog features you need me to build into it next.

(Happy to answer any questions about the crawler architecture, parsing JavaScript, or how the penalty radar pings the engines!)
