(Developh Pro)

Already have a site?

We audit it, fix it and look after it every month. Even if another team built it.

Combines Google PageSpeed, Vercel's Is Agentic and our own reading. Takes between 20 seconds and a minute and a half. If the site has no Is Agentic report yet, the one created there is public.

What changes, we keep up with

The web changes every week: laws, search engines, AI agents, frameworks. Keeping up with it is part of the job.

    Sites for agents

    AI agents already browse and buy. Is Agentic, by Vercel Labs, is the yardstick we use to measure it.

  6. Every weekDeveloph OS

    Our internal system

    It re-measures PageSpeed, Is Agentic and code health on the projects we look after, and tells us what to fix before anyone notices.

What the machine doesn't see

Automated tests measure speed and technical rules. What makes a site sell lives elsewhere, and that's where we spend most of our time.

  1. Conversion

    Where people give up: forms, checkout, bookings and buttons that lead nowhere.

  2. Message

    Whether in five seconds it's clear what you sell, to whom and why it's you.

  3. Technical and local SEO

    Indexing, page structure, structured data and showing up in searches near you.

  4. Real performance

    Speed on real phones, with your visitors' data and not just the lab.

  5. Accessibility

    Contrast, keyboard navigation and screen readers. Fewer people left at the door, and the law on your side.

  6. Code and hosting

    Outdated dependencies, form security, backups and what you pay for servers.

How it works

  1. Audit

    We go through the whole site and tell you plainly what works, what doesn't and what's costing you money.

  2. Fix plan

    We put the fixes in order, starting with what matters most to your business.

  3. Every month

    We work on the site with you. We're on Slack, email and calls. Not a ticket queue.

Developh Pro: website audit and monthly retainer

Developh Pro is the Developh studio's monthly retainer for websites and web apps that already exist, including sites built by another agency or team. It starts with a technical audit, turns the findings into a fix plan ordered by business impact, and continues with monthly work on the site: updates, new features, design tweaks, performance reviews, audits and strategic advice. The team is on Slack, email and calls, not a ticket queue. Every project Developh builds includes Developh Pro.

The page hosts the Developh scanner, free: enter a public address and three lanes run live. Google PageSpeed Insights (Lighthouse, mobile) gives the performance, accessibility, best-practices and SEO scores, lab metrics, real-visitor Core Web Vitals when Google has them, and the heaviest failing audits. Is Agentic (Vercel Labs) streams about 125 agent-readiness checks and a score. The Developh reading interprets the same Lighthouse run: security headers, third-party ads and analytics against GDPR consent, JavaScript libraries and page weight. A link of the form https://www.developh.co/developh-pro?site=example.com runs the scan on load. It is an automated snapshot. The full Developh audit is done by people and also looks at conversion and UX, content and message, technical and local SEO, accessibility, code, security and hosting.
