Fix slow website speed — done properly, by senior engineers
A slow site is rarely one problem — it is usually a stack of them: an oversized JavaScript bundle, render-blocking fonts and CSS, unoptimised images, a chatty API, and a handful of third-party scripts each adding a few hundred milliseconds. Generic "speed up your website" advice treats the symptoms; we treat the cause. We start from real-user data and a full waterfall trace to find the few changes that actually move your load time, rank them by impact, and ship them as reviewable pull requests. The goal is not a one-time Lighthouse screenshot — it is a measurably faster experience for the visitor on a mid-range Android phone over 4G, locked in with a performance budget in CI so the next feature doesn't undo it.
What you're seeing
Pages take 4+ seconds to render, users bounce before content appears, and Lighthouse scores stay below 60.
Our approach
We profile real-user data, identify the top five culprits (oversized JS, blocking fonts, unoptimised images), and ship measurable fixes within a week — verified in CI so it never regresses.
Symptoms teams come to us with
- Lighthouse and PageSpeed scores stuck in the red on mobile
- Visitors bounce before the hero or content paints
- Search Console flags Core Web Vitals as "Poor" on key URLs
- The site feels fast on your laptop but crawls on real phones
What we check first
- Oversized JavaScript bundles and unused third-party SDKs
- Render-blocking CSS, fonts and tag-manager scripts
- Unoptimised images and a missing modern image pipeline
- Slow TTFB from cold starts, slow queries or chatty APIs
Concrete deliverables, no fluff
Every engagement ends with measurable, documented outcomes — no black-box agency reports.
- RUM-driven audit with line-level fix list
- Implementation of every critical fix
- Before/after metrics with screenshots
- CI performance gate to prevent regression
What changes after we ship
Lighthouse 90+ on mobile, with proof
We share before/after metrics and a WebPageTest filmstrip so the improvement is verifiable, not a claim.
A leaner critical path
Smaller bundles, inlined critical CSS, deferred non-critical scripts and a modern image pipeline cut first paint by 40–60%.
Faster server response
Where TTFB is the bottleneck we trace the slow query, cold start or synchronous call and re-architect the hot path.
A budget that holds the line
A CI performance gate prevents the slow-creep that quietly returns a few sprints after a one-off audit.
From brief to shipped fix
A transparent, low-risk process — a senior engineer reads your brief personally, and nothing starts until you approve a written plan and price.
01
Diagnose
A senior engineer reviews your brief, reproduces the issue, and pinpoints the real root cause — not the symptom — before any code is touched.
02
Scoped plan & quote
You get a written plan to fix Slow Website Speed, a firm timeline, and a fixed quote. Nothing starts until you approve it — no surprise invoices.
03
Ship the fix
We implement on a branch and open a pull request you review, working to your code-review standards on your repo — never a black box.
04
Verify & hand off
We verify on staging and production, share before/after evidence where it applies, and leave you a short hand-off note so the fix sticks.
Situations we handle
Bounce rate climbing with load time
Visitors leave before content paints. We get the first meaningful paint under control so the traffic you pay for actually converts.
A site that is fast on desktop only
Mobile Lighthouse is 30+ points behind. We profile on real mid-tier devices and close the gap.
Third-party bloat
Marketing tags and SDKs have ballooned the bundle. We audit, defer and sandbox them without breaking analytics.
Why teams hand this task to Krapton
Senior engineers only
Your brief is read and handled by a senior engineer — no junior hand-off, no sales-rep filter in between.
Root cause, not a patch
We reproduce and fix the underlying cause, then add a guard so the same class of issue does not quietly return.
Your repo, your standards
Every change lands as a pull request you review, on your repository, following your existing review process.
NDA on day one
Confidentiality and IP are covered before we look at a single line of code. All work stays in your accounts.
Fixed quote up front
You approve a written plan and price before work starts. If scope changes, we re-quote in writing — no surprise invoices.
Proof, where it applies
Performance, SEO and reliability work ships with before/after evidence so the result is measurable, not anecdotal.
Three ways to engage
No retainer required. Pick the model that matches the work — pricing for this task starts from $1,500, with a fixed quote before anything starts.
Per task
Most popular
One clearly-scoped fix at a fixed price. Best when you know exactly what is broken and want it handled end to end.
- Fixed quote up front
- One PR, reviewed by you
- No retainer required
Hourly
Pay only for the hours worked. Best for diagnostics, audits, or exploratory work where the scope is still emerging.
- Weekly timesheets
- Pay for what you use
- No minimum commitment
Per sprint
A focused 1–2 week sprint when the work is bigger than one fix but smaller than a full project.
- 1–2 week blocks
- Clear sprint goal
- Scale up or stop anytime
Industry-standard stack, no proprietary lock-in
Fix slow website speed — your questions, answered
How much does it cost to fix Slow Website Speed?
Pricing starts from $1,500 and depends on the scope we find during the diagnostic. You get a fixed, written quote before any work begins — most engagements like this run 1–2 weeks.
How long does it take to fix Slow Website Speed?
Typically 1–2 weeks for a focused engagement. After a short diagnostic we commit to a firm timeline so you know exactly what to expect.
Will you work directly on our existing codebase?
Yes. We work on your GitHub, GitLab or Bitbucket, ship every change as a pull request you review, and follow your code-review standards — not ours.
What exactly will I have at the end?
Concrete, documented outcomes — RUM-driven audit with line-level fix list, Implementation of every critical fix, Before/after metrics with screenshots, and more. No black-box agency report.
How quickly can you start, and do you sign an NDA?
For a focused task like this we can usually start within 24–48 hours of the brief. We sign an NDA on day one, before we look at any code — yours or ours.
Will this improve my Core Web Vitals and Google rankings?
Directly. We fix the metrics Google actually ranks on — LCP, INP and CLS — on real-user data, then lock the gains in with monitoring so they don't regress. Better field metrics typically support better rankings on competitive queries.
Will the speed gains last, or creep back over time?
They last — because we add a performance budget gate to your CI. Most one-off audits regress within a few sprints; the CI gate fails the build if a change blows the budget, so the wins are protected by default.
