The short answer

Asking Lovable or Replit to patch it again keeps you in the same tool that built it, which is often how the app got stuck in the first place. A marketplace hire from Upwork, Toptal, Arc.dev or Fiverr brings in a person to scope the bug, write the patch and invoice the hours, but stops there once it ships. A fixed-price partner like Continuum reads the live app, fixes what AI left unsafe or incomplete for one agreed price, then runs the weekly work that gets the fixed app its first real users.

The part nobody mentions

The AI said it fixed it. Nobody checked.

Ask Lovable or Replit to fix the bug and it will tell you it is fixed. The demo looks right, the page loads, and there is a real chance it still is not fixed: the same model that built the hole is grading its own work, and it has no way to tell you what it cannot see.

I fix it and get you your first users, because a fix nobody outside the tool has checked is a claim, not a fix. Get Users is the ongoing work, AEO and SEO, read every week, that makes the fix worth having paid for once it actually holds.

Side by side

What each option does, who owns the code, and what happens after it ships.

Price shapes for Lovable, Replit and the four marketplaces are described structurally, not as a dollar figure: none of them quote one rate for a fix, so check your own plan or their listings. Continuum's numbers are pulled straight from the live price list.

Lovable, Replit, Upwork, Toptal, Arc.dev, Fiverr, a freelancer and Continuum, compared on what each does to fix a stuck AI-built app, who owns the code, and what happens after it ships.
Option	What it is	Price shape	Who owns the code	After it ships
Lovable	The AI builder you already used. Ask it to generate another pass at the same bug, in the same codebase.	Your existing Lovable plan or credits, no separate quote	You, same as before	Whatever it generates ships untested by a person. Nobody is checking whether the fix actually holds.
Replit	The AI builder or Agent you already used. Another prompt, another attempt, in the same tool.	Your existing Replit plan or Agent credits	You, same as before	Same risk as Lovable: another AI pass, not a person checking the fix actually holds.
Upwork	Open marketplace. You post the bug list and interview whoever bids.	Hourly or fixed-bid, set by the freelancer you pick; wide range.	Per the contract you write	The contract closes when the bugs are fixed. Nobody is checking whether the app gets used afterward.
Toptal	Vetted engineer network; faster to trust the skill level, slower and pricier to engage.	Hourly, at a premium for the screening.	Per the contract through Toptal	Same shape as any contractor: billed hours end, the relationship ends with them.
Arc.dev	Remote-developer recruiting, closer to a staffed hire than a one-off task.	Hourly or salaried-style monthly, negotiated in the offer.	Per the contract through Arc	You either keep paying for a developer whose brief was never "get this app used", or the role ends.
Fiverr	Fixed-price gigs bought off a seller profile. Fast and cheap for a narrow, well-defined bug.	Fixed per gig, usually the cheapest of the four.	Per the gig terms	Gig marked complete. Nothing in it was aimed at getting the app its first customer.
A freelancer you already know	Someone in your network. Good when you already trust them and the fix is small.	Whatever you agree, usually hourly	Per whatever you agree, often informal	Depends on the person. Most are not set up to also run growth and measurement.
Continuum, fixed-price partner	One senior engineer reads the live app, finds what AI left unsafe or incomplete, and fixes it to a written scope.	Ship Fix: $4,000 to $15,000, agreed before work starts; a free Leak Check first	You, fully, from day one	Get Users starts: $500/mo, month to month, cancel anytime, a weekly read on whether AI names you.

FAQ

Fixing a stuck AI-built app, straight answers.

The same need shows up as "who can fix my AI-built app before launch", "fix my ai built mvp", "senior engineer to fix my mvp", "finish my half built supabase app", "fix my app auth and rls before launch", "make my vibe coded app production ready", and "take my vibe coded app to production". All of them are the same moment: an app an AI tool mostly built, and something in it that is not safe to launch yet.

In our own stored checks (notes/cited-not-named-continuum-2026-10-08.md), AI answers to this question name Lovable and Replit most, the AI build tools themselves, and Upwork as the human option, far more than any single fixed-price practice. That is a gap in how often a page like this gets written and cited, not a gap in whether the work gets done well.

They can keep generating more code in the same tool, which is often how the app got stuck in the first place. AI is strong at the visible surface and weak at exactly the parts a launch depends on: payments that clear, auth that holds for strangers, an admin view, and security. A second pass from the same kind of tool does not reliably fix that. A person who reads the live app from the outside does.

No. Start with a free Leak Check, a read of the live app from the outside, no code access needed, before you decide anything.

With a marketplace hire, usually nothing. The ticket closes and the relationship ends. Continuum treats the fix as rung one and Get Users, the ongoing AEO and SEO work, as rung two, because a fixed app with no users still needs no care.

Already inside Lovable or Replit and the bug looks small? Try another prompt first, it costs nothing extra to attempt. When that does not hold, a narrow, well-defined bug and a tight budget point at Fiverr or a freelancer you manage yourself. A bigger, ongoing need points at Toptal or Arc, if you plan to manage the relationship. Wanting one price before you start, full ownership, and someone still around once it ships points at a fixed-price partner.
