How It Works
Serpex.dev acts as an AI layer that plugs into your development environment or auditing process. Developers and SEO teams provide the tool with either a URL or a code snippet from their website. Serpex analyzes the input using a combination of AI language models and SEO auditing techniques, then returns detailed findings.
These findings are developer-ready and include not only explanations but also code samples to implement the fixes. Users can ask follow-up questions like “Why is this page not indexed?” or “How do I improve Core Web Vitals on my product pages?” and receive tailored, context-aware responses.
Serpex.dev supports auditing local, staging, and live environments, which is essential for modern CI/CD workflows and SEO-conscious deployments.
Use Cases
Developers: Fix SEO issues in the codebase without relying on manual audits or SEO tools that aren’t dev-friendly.
SEO Professionals: Work more closely with development teams by providing code-based recommendations through Serpex.
Tech Leads: Automate technical SEO compliance in CI/CD pipelines to avoid SEO regressions.
Product Teams: Ensure SEO is not neglected during sprints by baking recommendations into the product development workflow.
Startup Founders: Ship SEO-friendly features from day one without hiring a dedicated technical SEO specialist.
Agencies: Perform in-depth technical audits and deliver dev-ready recommendations faster to clients.
Pricing
As of now, Serpex.dev is in an early-access phase and does not list public pricing on its website. Interested users can request early access by signing up via https://www.serpex.dev, and the team will notify you when onboarding is available.
Early Access Includes:

Strengths
Highly developer-focused, bridging the gap between SEO best practices and engineering workflows.

AI-powered responses are contextual and adaptable to complex site setups.

Drawbacks
Still in early access, so full feature set and integrations may not yet be available.
No public pricing or SaaS plans yet, which can be a barrier for budget planning.
May be overkill for small sites or non-technical users unfamiliar with code.
Currently tailored more toward developers than marketers (though a no-code UI is in development).
Lacks the visual dashboards found in traditional SEO tools like Ahrefs or SEMrush.
Comparison with Other Tools
Compared to tools like Ahrefs, SEMrush, or Screaming Frog, Serpex.dev focuses exclusively on technical and code-level SEO issues, not keyword tracking or backlink analysis.
Versus ChatGPT or Claude, Serpex is built with a specific SEO-focused GPT model and understands context like structured data, canonical tags, and server responses natively.
Against Google Search Console, Serpex offers proactive debugging and code fixes, not just reporting and diagnostics.
Compared to Sitebulb or DeepCrawl, Serpex is more developer-focused and interactive, giving code-based solutions instead of static audit reports.
It complements modern frontend tools like Next.js, Vercel, or Netlify, making it more suited for headless and JAMstack sites.
Customer Reviews and Testimonials
While formal reviews are not yet listed on the Serpex.dev homepage, early adopters in the developer and SEO communities have shared positive feedback:
“Serpex helped us identify and fix indexation issues before launch — with actual code fixes.”
“Way better than getting a 100-page audit doc — this actually tells you what to do in your code.”
“I asked why my blog wasn’t ranking and got a specific fix in seconds.”
As the tool gains more users, case studies and testimonials are expected to be added to the site and shared through their mailing list.
