Debugging often starts with the same frustrating workflow:
Copy error → open Google → search Stack Overflow → inspect five different answers → try three fixes → repeat.
So I built TraceFix, a developer-focused web application designed to make that process much faster.
TraceFix combines an error-search interface with an AI workspace where developers can paste compiler errors, runtime exceptions, stack traces, or broken code and get a structured explanation of what went wrong and how to fix it.
TraceFix is designed around multiple programming ecosystems, including:
This isn't designed as a client-side Gemini wrapper.
The application uses a zero-trust API architecture:
Browser
↓
Clerk authentication
↓
Protected Next.js Route Handler
↓
Subscription verification
↓
Rate limiting
↓
Google Gemini API
↓
Streaming response
↓
Developer workspace
The Gemini API key never reaches the browser and is kept exclusively in server-side environment variables.

Developer experience
I wanted the interface to feel closer to a serious developer tool than a typical AI chatbot.
The UI focuses on:
- Fast error searching
- Language filtering
- Structured explanations
- Root-cause analysis
- Fix recommendations
- Syntax-highlighted code
- Copy-to-clipboard
- Streaming AI responses
- Responsive developer workspace
No unnecessary gamification or childish UI — just a clean workspace built around debugging.
Security was a major part of the project
The API layer validates the Clerk session before processing requests, checks subscription state server-side, applies rate limiting, and only then communicates with Gemini.
Stripe webhook signatures are verified using the raw request body before subscription state is updated.
What's next?
The next iteration can connect TraceFix to real developer knowledge sources such as:
- Stack Overflow
- GitHub Issues
- Official language documentation
- Package documentation
- A RAG-based error knowledge base
The goal is to combine AI reasoning + real-world solutions + official documentation instead of relying solely on model knowledge.
🚀 Launching tomorrow
TraceFix will be live by August 16, 2026 at 12:00 AM UTC.
I'm excited to finally put it in the hands of developers and see how useful it actually is outside my own development workflow.
Built with Next.js, TypeScript, Tailwind, Clerk, Stripe, Resend and Google Gemini.
