Performance audit: Find out where the milliseconds went.

Slow software costs you quietly. Visitors leave before the page paints, search rankings slip, and app users give up on a sluggish list long before they reach checkout.

Our performance audit measures where the time goes: network, JavaScript, rendering, or the database. We turn that into a ranked list of fixes, each with its expected gain. No guesswork, and no “rewrite it in something faster”.

Sound familiar?

Everyone agrees it’s slow. Nobody knows why.

  • Core Web Vitals are red and search traffic is sliding.
  • The app takes seconds to start, and lists stutter on older phones.
  • The JavaScript bundle has grown with every sprint.
  • Pages that flew with test data crawl with real data.
  • The hosting bill keeps climbing, but nothing feels any faster.
Scope

What we cover

Every audit covers the same ground, so nothing important depends on what we happen to notice.

How it works

Four steps, one clear report.

  1. Step 01

    Baseline

    We measure how the pages and screens that matter perform today, on the devices your users have.

  2. Step 02

    Profile

    We profile each slow page and screen to find where the time goes, from the network down to the database.

  3. Step 03

    Prioritise

    Every fix is ranked by expected gain and effort, so you do the valuable ones first.

  4. Step 04

    Report & walkthrough

    Findings and a fix plan, walked through with your engineers.

What you walk away with
  • Baseline metrics for key pages, screens, and devices
  • A ranked list of fixes with expected impact
  • Quick wins you can ship right away
  • Performance budgets and monitoring to stop regressions
  • A walkthrough with your engineering team

Who it’s for

FAQ

Good questions, straight answers.

Something we missed? Ask us directly. A person will answer, not a bot.

  1. 01Do you audit mobile apps as well as websites?

    Yes. We cover Next.js and React web apps and React Native / Expo mobile apps, testing on real devices as well as in the lab.

  2. 02Do you need access to production?

    Read-only access to the code and your monitoring or analytics helps a lot. We never need to change anything in production.

  3. 03Will you implement the fixes?

    If you’d like. Many fixes are quick wins your team can ship; for the bigger ones, we can quote a fixed-scope performance project.

  4. 04Will this help our SEO?

    Core Web Vitals are a search ranking signal, so improving them can help. Faster pages convert better either way.

  5. 05What if the problem is our backend?

    Then we’ll find it. We follow the time wherever it goes: database, APIs, third-party scripts, or infrastructure.
