How Much Does It Cost to Rescue a Vibe-Coded App?

What you're paying for

A vibe-coded MVP is a real piece of software with real users — but most of what it lacks is production engineering work that AI tools don't do automatically. The rescue is paying a senior engineer to add the missing layer.

The scope of work falls into four buckets, in roughly this order of urgency:

• Critical (must-fix): Security holes, missing backups, broken auth. Things where one bad day ends the business.
• Production basics: Error tracking, server-side validation, migrations in version control, staging environment.
• Durability: Background jobs, indexes, rate limiting, deploy pipeline, real error handling.
• Growth: Scaling work, refactoring problem areas, building features properly going forward.

Tier 1: code audit ($3,000-$8,000)

When: You're not sure how bad the situation is. You want a written diagnosis before committing to remediation budget. Your investor or co-founder wants an objective third-party assessment.

What you get: A structured audit covering security, data integrity, architecture, dependencies, and infrastructure. A red/amber/green report with specific issues and recommended fixes. A cost estimate for remediation work.

Typical timeline: 3-7 calendar days.

Caveat: An audit doesn't fix anything. Most teams use the audit to scope and prioritize the actual remediation work that follows. See our Code Audit service.

Tier 2: critical fixes only ($5,000-$15,000)

When: You have real users now and you can't wait. You need the business-ending issues fixed before you do anything else.

What you get:

• Exposed secrets rotated and moved server-side
• Row-level security audited and fixed
• Automated daily backups + one successful restore test
• Auth tightened — server-side session validation, rate limits, MFA available
• Hard spend caps on paid APIs

Typical timeline: 1-2 weeks.

Caveat: This stops the bleeding but doesn't finish the job. Most teams that do critical-fixes-only come back for the rest within 60 days.

Tier 3: full production-readiness ($25,000-$60,000)

When: You have real traction and need the app to actually be reliable. You're raising, hiring engineers, or just tired of every release feeling risky.

What you get: All of Tier 2 plus:

• Server-side validation across every endpoint
• Error tracking (Sentry or similar) wired in
• Structured logs + uptime monitoring
• Database migrations in version control + staging environment
• Database indexes audit + critical missing indexes added
• Background job system for slow work (email, file processing, LLM calls)
• Rate limiting on auth + paid API endpoints
• Real error handling pass — no silent swallows, no exposed stack traces
• CI + protected branches + 5-minute rollback procedure
• Architecture diagram, runbooks, and incident playbook

Typical timeline: 2-6 weeks, depending on size and complexity.

Why the range: $25k-$60k spans the realistic variance. A simple SaaS app with a clean data model is near the low end. An app with payments, file uploads, LLM integrations, and tangled business logic is at the high end.

Tier 4: ongoing engineering support ($10,000-$25,000/month)

When: You want to keep shipping with senior engineering quality but you're not ready to hire a full-time team yet.

What you get: A senior engineer (or small team) embedded in your codebase month-to-month. Feature work, infrastructure work, mentorship for whoever you do hire, on-call coverage. Variable hours based on need.

See our post on staff augmentation vs hiring vs agency for when this model is right vs the alternatives.

What pushes the price up

• Payments and money flow. Stripe integrations done wrong, no idempotency, no reconciliation. High-stakes work to fix.
• LLM features in production. Spend control, eval harnesses, prompt versioning, fallback handling — additional scope.
• Compliance requirements. SOC 2, HIPAA, or even basic GDPR audits add weeks.
• A bad data model. If the database schema needs restructuring, the project becomes a partial rebuild.
• No documentation, no original developer. Time spent reverse-engineering business logic.
• Active users you cannot disrupt. Migration work has to happen with zero downtime.

What keeps the price down

• A clean data model. Most vibe-coded apps actually have reasonable schemas — easy to build on.
• Standard stack. Next.js + Supabase rescues are routine. Custom or exotic stacks cost more.
• No live users yet. No migration work, no zero-downtime constraint.
• Smaller surface area. Fewer features = less to harden.
• Willingness to defer. Doing Tier 2 now and Tier 3 later spreads cost over runway.

Rescue vs rebuild cost comparison

People often ask whether it's cheaper to rescue or rebuild. For most vibe-coded MVPs, rescue is dramatically cheaper:

The rebuild option only makes sense when the data model is fundamentally broken or you have very little working functionality to preserve. For more on that decision, see rescue vs rebuild: a decision framework.

How to budget for this

• If you're pre-revenue: Start with an audit ($3-8k) and Tier 2 critical fixes ($5-15k). Don't do the full Tier 3 yet — fix only what would kill you.
• If you have early revenue: Tier 3 is the right scope. Spend the $25-60k once and stop spending engineering cycles on incidents.
• If you've just raised: Tier 3 + ongoing staff aug. Spend a chunk of round cleaning up before you hire engineers — it makes the hires more productive.
• If you're bootstrapped and growing: Audit, then phase the rescue work over 2-3 months as cash flow allows.

Red flags in rescue pricing

• Quotes much lower than these ranges. A $5k full rescue from an offshore freelancer is almost always a junior engineer making the problem worse.
• Quotes much higher than these ranges. Large agencies sometimes quote $150k+ for what is genuinely Tier 3 work. You're paying for their overhead.
• A fixed-price quote without an audit. Anyone giving you a number without looking at the code is guessing. Audit first, then quote remediation.
• “Rebuild it from scratch” as the default recommendation. Sometimes correct, but anyone who recommends a rebuild without going through the data model first is usually selling rebuild hours.

Frequently asked questions

How much does it cost to fix a vibe-coded app?

Fixing a vibe-coded app typically costs between $5,000 and $80,000 depending on scope. A code audit runs $3-8k. Critical security and backup fixes alone run $5-15k. Full production-readiness (security, backups, observability, error handling, deploys, performance) runs $25-60k. Ongoing engineering support after the rescue runs $10-25k/month.

Is it cheaper to rescue or rebuild a vibe-coded app?

Rescue is almost always cheaper if the data model is sound and the app has working functionality. A rescue runs $25-60k and takes 2-6 weeks. A rebuild typically runs $80-250k and takes 3-6 months. The rebuild option only makes sense when the data model is fundamentally broken or the app has very little working functionality to preserve.

What does an AI app code audit cost?

A focused code audit for an AI-built MVP runs $3,000-$8,000 depending on the size and complexity of the codebase. The output is a written report covering security, data integrity, scalability, and remediation priorities — with a remediation cost estimate. Most audits take 3-7 days.

Should I hire a freelancer or an agency to rescue my app?

For vibe-coded app rescues specifically, look for a senior engineer or small specialist agency that has done this work before. Junior freelancers often make the problem worse. Large generalist agencies tend to overscope. The right fit is usually a small team with deep production engineering experience.
