The short answer
ZoopCoder fixes one reproducible bug in an existing React, Next.js, Vue or Angular web app — a hydration error, a crash after a Next.js upgrade, a broken route, a form that will not submit — for a fixed ₹1,499 per issue, returned as a pull request or code diff in 2-3 working days. A Next.js hydration error looks like one bug but the Next.js docs list seven separate causes: invalid HTML nesting such as a div inside a p tag, window or localStorage used during render, the Date() constructor used during render, browser extensions that edit the page, a misconfigured CSS-in-JS library, a typeof window check in rendering logic, and an edge or CDN setting such as Cloudflare Auto Minify that rewrites the HTML before React sees it, so the first job is finding which one, not wrapping everything in useEffect. Since Next.js 15, cookies(), headers(), draftMode(), params and searchParams are asynchronous and must be awaited, which is why a route that worked on Next.js 14 can start throwing after an upgrade.
What you get
- The project cloned and run locally from your repository before anything is changed
- The issue reproduced in the browser, or a written explanation of what is needed to reproduce it
- Root cause traced through the component tree, state management, routing or API layer
- The fix written as the smallest change that solves it, in your existing code style
- The exact pull request or code diff, so your own developer can read and keep the change
- Tested in Chrome and one other browser, on desktop and mobile widths
- A short written note on what caused it
- Up to 2 rounds of revisions if the same issue is still not fixed

Not included

- WordPress, WooCommerce, Shopify or plain PHP/HTML sites — that is our Website Bug Fix service (₹999)
- Backend or server-side faults that merely surface in the frontend — quoted after diagnosis

- Multiple unrelated issues (each is ₹1,499)
About this service
This is the same fixed-scope, one-bug-one-price idea as our Android and iOS bug fix services, aimed at the modern JavaScript frontends our generic Website Bug Fix explicitly does not cover. A React, Next.js, Vue or Angular app is a compiled single-page application with its own dependency tree, build step and client-side routing — debugging it means running the project locally and reading the component tree, not checking for a plugin conflict. We ask you to describe the bug before you pay, because some frontend symptoms are actually a backend API returning the wrong data, and no amount of frontend code change fixes that; if that is what yours is, we say so and point you at the right service instead of taking the order. The fix is scoped to the issue you reported — if fixing it uncovers that a section needs rebuilding, we quote that separately rather than quietly expanding the job.
Questions before you buy
What counts as one issue?
One reproducible fault with one cause — a component that crashes, a form that will not submit, a route that 404s, a state bug that only shows up after a certain action. If two symptoms share a single root cause, that is still one issue.
What if you cannot reproduce it?
We tell you what we tried and what we need from you — usually a screen recording, the exact browser and steps, or a test account. If it genuinely cannot be reproduced or traced from the console, we refund rather than bill for guesswork.
Is this different from your Website Bug Fix service?
Yes. Website Bug Fix (₹999) is priced for WordPress, WooCommerce, Shopify and plain PHP/HTML sites. This service is for React, Next.js, Vue, Nuxt or Angular apps — a different codebase shape that needs a frontend developer running the build, not a CMS-plugin checklist.
Do you need my source code?
Yes, always. We fix the bug in your project and hand back a pull request or diff so you keep the change. We do not work from a minified production bundle.
Can you fix a bug in a Next.js API route or server component?
Yes, if the bug is in your own Next.js code. A fault in a separate backend service you call from the app is diagnosed as part of the price, but the backend fix itself is quoted separately.
Will you deploy the fix for me?
We hand back the pull request or diff; merging and deploying through your own CI/CD or hosting is quoted separately since that access varies a lot between projects.
Why does my Next.js app show a hydration error?
The server-rendered HTML and what React builds in the browser do not match. The Next.js docs list seven causes, including invalid tag nesting (a div inside a p), window, localStorage or Date() used while rendering, a browser extension editing the page, and a CDN feature such as Cloudflare Auto Minify rewriting the HTML. We reproduce it, find which cause applies and fix that one, rather than hiding the warning.
My Next.js app broke after upgrading to version 15 — is that a bug?
Usually it is a breaking change rather than a bug: in Next.js 15 cookies(), headers(), draftMode(), params and searchParams became asynchronous. Fixing the one route or page that throws is a single issue. Migrating a whole codebase across a major version is an upgrade and is quoted separately; Next.js ships a codemod that automates much of it.
