The Tech Stack Behind Every AI App We Rescue
AI-generated apps almost always output one of 10 standard technologies. Lovable ships React. V0 defaults to Next.js. Bolt reaches for Node.js. Cursor writes whatever the prompt specifies. The result is a predictable short list of frameworks, languages, and styling systems, and AppStuck has production depth in all of them. If your app is stuck, the technology is not the problem. We are the solution.

Why your AI app's tech stack matters for rescue
The platform you used to generate your app almost certainly made a technology choice on your behalf. Lovable chose React. V0 chose Next.js. Bolt defaulted to Node.js. That choice determines everything about how the app is structured, how it fails in production, and what it takes to fix it. A developer who doesn't know React deeply can't debug a Supabase RLS issue in a Lovable app. A developer who hasn't shipped Next.js to Vercel before can't diagnose a missing edge-function environment variable in a V0 project.
When you prompted Lovable or Bolt to build your app, the platform translated your natural-language description into a specific technology stack. That stack is now your app. The bugs you're hitting, the features that won't build, the deploy errors that loop — they are all expressions of how that technology behaves in production environments the AI tool never tested against. Fixing them requires knowing the technology, not just the platform.
General-purpose freelancers fail here because they don't have the accumulated pattern recognition. They haven't seen React-plus-Supabase fail in the same way across a hundred different projects. They don't know that TypeScript errors in Lovable output are almost always caused by a specific misuse of generic types that the AI repeats consistently. They haven't fixed the same Tailwind CSS purge issue in a Bolt export a dozen times. We have.
The tech stack is not an obstacle — it's a map. Once we know which technologies your app uses, we know where to look, what to test, and how long it will take to fix. That's why technology depth is the first thing we assess and the thing we're most deliberate about matching to your project.
Frontend technologies
These are the UI frameworks and styling systems that AI platforms output most often. Each one has its own production failure patterns — and we've resolved all of them across hundreds of projects.
Backend and language technologies
The languages and runtimes that power your app's server-side logic, APIs, and data handling. AI platforms reach for this short list almost every time.
Tech stack by platform
Every major AI app platform has a preferred tech stack. Knowing which one your app uses tells us exactly where to look when things go wrong in production.
| Platform | Frontend | Backend | Default Styling |
|---|---|---|---|
| Lovable | React | Supabase (PostgreSQL) | Tailwind CSS |
| Bolt.new | React / Vue | Node.js | Tailwind CSS |
| V0 | Next.js | Node.js / Vercel Functions | Tailwind CSS |
| Cursor | Prompt-driven (any) | Prompt-driven (any) | Tailwind CSS / CSS modules |
| Claude Code | Prompt-driven (any) | Prompt-driven (any) | Tailwind CSS / CSS modules |
| Replit | React / Python templates | Python / Node.js | CSS / Tailwind CSS |
| Bubble | Bubble runtime (not portable) | Bubble runtime (not portable) | Bubble CSS |
| FlutterFlow | Flutter / Dart | Firebase / Supabase | Flutter themes |
Bubble and FlutterFlow are exceptions. Their output is tied to the platform's runtime and is not portable code. We still rescue Bubble and FlutterFlow projects, but the process is different.
Don't know your stack? We'll figure it out
Most clients who come to us don't know what technology their app uses — and that's completely normal. You described your idea, the platform generated the code, and now it's not working. You shouldn't need to know whether it's React or Vue to get help. That's our job. When you submit your project through our AI app rescue service, we identify the tech stack in the first hour of assessment and use that knowledge to diagnose what's wrong.
What matters is not what the technology is — it's whether the person fixing it knows it well. We do. Whether your app is React or Vue, Next.js or Astro, Python or Node.js, we have engineers with production depth in that stack who've fixed the same class of problems dozens of times before. Get in touch and we'll take it from there.
Platforms that use these technologies
These are the AI code generators and no-code platforms whose output we rescue most often. Each one defaults to one or more of the technologies listed above.
