For businesses that run on a web app

Bug Fixing Service for Web Apps one-off, no retainer

A sign-in, checkout, deploy or API flow stopped working? Send us the bug. We reproduce it, find the cause and fix it when the scope allows. We fix the app you already have. You pay once, and there is no subscription. You do not need to hire a full-time developer or start an agency retainer for one bug.

Start a $99 Incident Diagnosis

Tell us which flow is broken. We reply during working hours and tell you if an Incident Diagnosis is the right first step.

What's broken?

We provide bug fixing services for the web apps that SaaS companies, startups and agencies use to run their business. Most requests start with one of these problems:

  • Customers cannot sign in or sign up, and revenue stops
  • Payments failing: checkout errors, or the customer paid and never got access
  • Worked yesterday, broken after a deploy
  • API and webhook failures, such as a third-party call that stopped working
  • A page or flow returns a server error or a blank screen, or a list that used to have data comes back empty

What you get

  • Reproduction of the problem on your web app
  • Evidence-based diagnosis of what broke and why
  • A route to the fix, and the fix itself where the scope covers it
  • The affected flow tested, plus a written close-out covering what was fixed, how we verified it and what stays open

What we do

This bug fixing service has three steps:

  1. Reproduce

    We trigger the bug on the running app and record what it does now.

  2. Diagnose with evidence

    We establish what broke and why, whether that was a deploy, a setting, a key or a change on a provider's side.

  3. Change, test, hand over

    We make a reasoned change within the agreed scope, test the affected flow, and hand over a written close-out covering what was fixed, how we verified it and what stays open.

Simple, upfront incident pricing

Incident Diagnosis

$99

Covers one incident in one app and the systems directly connected to it. You get the evidence, the risk and a fixed or capped repair proposal.

Credited toward an approved repair.

Complex Rescue

$750–$1,500+

Multi-service failures, custom code, data repair, migration impact or higher-risk production changes.

Written scope, cap, rollback plan and acceptance criteria before work begins.

These are indicative ranges, not automatic quotes. You approve the written scope and price before any repair work begins. Third-party platform and usage fees are not included.

Who we are

The tools are new.
Production discipline is not.

App Rescue Desk is a Rivetra Labs service. We fix production bugs and restore broken workflows in the web apps that businesses run on. The desk is led by its founder, a principal engineer with 30 years on production systems that were not allowed to go down. AI can build an app fast. The hard part is to know which error log to trust, what not to touch and when to roll back. Then you have to explain that decision to someone who does not read stack traces.

That is why the work runs as a desk. One named owner is accountable for your engagement from the first look to sign-off. We write the work down and it gets a second review, so your app does not depend on one person's memory. We do not change production without your written approval. Each engagement is one-off, and there is no retainer.

How these bugs happen

The web app worked before. Then something changed: a deploy; a dependency, a key or an environment variable that never reached production; or a change on the other side of payments, auth or an API. That is why we look for what changed first.

Often the bug behind these symptoms is a default that nobody changed, or a setting that belongs to one environment and not to another. Five such causes sit behind the list above. From the outside they look the same, because all of them produce one result: an app that used to work and no longer does.

A payment that goes through while your app never hears about it

A Stripe webhook endpoint holds a different signing secret for test and for live, even on the same URL. Carry the test secret into production and the card is charged while the account never opens on yours. Checkout never looks broken; the first you hear of it is a customer asking where their plan went.

A build that assembled different packages than the ones you tested

npm install uses lockfile versions as long as they still satisfy package.json; when they don't, it resolves newer ones and rewrites the lockfile. npm ci refuses and fails the build instead. One repository can therefore ship a different set of dependencies than the one that passed locally.

A key that exists in the dashboard and not in the build

Values Next.js hands to the browser are prefixed NEXT_PUBLIC_ and get baked into the bundle when it is compiled. Promote a build from staging and it carries the values from where it was built. A variable changed in the dashboard takes effect on the next deployment, not the one already live.

Data that is there and invisible

Switch row-level security on and Postgres denies by default: with no matching policy, a read returns zero rows and no error. The row saved, but the query that should display it comes back empty. Checking the table as its owner will not show you this.

A sign-in link that lands nowhere

An auth provider only sends users back to URLs it has been told to trust. A live domain missing from that list breaks confirmation and password-reset links while the sign-in form itself still looks correct. The email arrives and the link it contains does not resolve.

In all five cases, Stripe, Node, Next.js and Postgres work as designed. The cause is a default value or a boundary between environments. A symptom does not point to one cause: a blank screen fits at least three of them. So we reproduce the failure on your running app first, and only then name the cause.

What we work on

We restore previously working flows in live web applications.

The app
An existing web app with a production flow that worked before.
The stack
React, Next.js, TypeScript, Node.js, Supabase and PostgreSQL.
Connected services
Authentication, Stripe payments, email and deployment services.

What's not included

  • WordPress or other CMS, plugin or theme work
  • Hacked-site or malware cleanup, penetration testing or live breach response. Contact a security-incident specialist and do not use a public form
  • PHP/Laravel, Rails, MERN-specific work or native iOS/Android apps
  • New apps or features, full rewrites, long modernisation or visual redesign
  • Maintenance retainers or monthly plans
  • Game or Roblox scripts, Windows services, Kubernetes administration or electronic bug sweeps
Can I hire a developer to fix one bug without a subscription or retainer?

Yes. App Rescue Desk fixes one production bug as a one-off engagement. There is no subscription or monthly retainer, and no need to add a developer to payroll. We diagnose first and complete only the repair you approve.

How much does a bug fixing service cost?

Every incident starts with a $99 Incident Diagnosis, credited toward an approved repair. A Standard Restore is typically $249–$499; a Complex Rescue is generally $750–$1,500+. You approve the scope and fixed or capped price before any production change.

Process and pricing logic: how it works.

What counts as one bug or one incident?

One incident is one failed production flow in one app, including systems directly connected to that failure. Unrelated bugs, new features, redesigns and rebuilds are separate scopes.

Do you fix WordPress sites or native mobile apps?

No. We fix live web apps built with React, Next.js, TypeScript, Node.js, Supabase, PostgreSQL and Stripe. We do not take on WordPress or other CMS work, or native iOS and Android apps.

Check the supported web app stack and service exclusions.

What happens if the bug is intermittent or cannot be reproduced?

Intermittent bugs can qualify if logs or a reliable trigger make them observable. If an accepted incident still cannot be reproduced after access is provided, the diagnosis fee covers the investigation and you receive a written close-out.

Read the refund and cancellation terms.

Can you fix an AI-built or vibe-coded app made with Lovable, Cursor, Bolt, v0 or Replit?

Yes, if it is a live web app on the supported stack and a previously working flow is broken. We work from the code, deployment and connected services, regardless of the builder. App Rescue Desk is independent of these platforms.

For a Lovable app, start with the Lovable app production bug-fixing service.

Can you recover my account on Google, Stripe or another platform?

No. We can repair sign-in and integrations inside your app, but we cannot recover an external Google, Stripe or other platform account or bypass its identity checks.

What information do you need to diagnose my bug?

Answer the questions in the bug-fix request form. That is enough for our initial review; we will ask if anything else is needed.

Start a one-off bug fix request.

What happens after I send a bug fix request?

A human reviews your request and replies with the next step. A reply does not mean technical work has started. We begin after the scope, required access and price are agreed in writing. If the incident needs a temporary step before the permanent repair, we describe them separately.

Send the bug.

Tell us which flow is broken. We reply during working hours and tell you if an Incident Diagnosis is the right first step.
