๐ How We Built an Instant AI Security & Code Auditor in Next.js & Convex
When building security or code auditing tools, speed is everything. Developers won’t wait 45 seconds for a bloated PDF reportโthey want instant feedback on potential bugs, security leaks, or bad practices.
Over the last week, we’ve been building BugZ AI, a lightweight scanner designed to analyze code repos and security links in under 5 seconds.
Here is a breakdown of our stack and the architecture choices behind keeping real-time scans ultra-fast.
๐ก Build in Public Update: We hit 175 total developer visits today on Day 4 of building out in the open!
๐ ๏ธ 1. The Tech Stack
- Frontend: Next.js 15 (App Router) + Tailwind CSS
- Backend & Database: Convex (for real-time reactive updates without manual polling)
- Auth: Clerk
- Mobile Sync: Capacitor (wrapping web assets into native Android)
โก 2. Solving the Speed Bottleneck
The biggest challenge was stream handling. Instead of waiting for the entire LLM response to complete before rendering analysis to the UI, we used Convex’s real-time mutations paired with edge streaming.
This lets the user paste a link or snippet and see initial vulnerability checks pop up in real-time within < 20 seconds.
๐ 3. What We Learned Building Out in the Open
- Keep the UI distraction-free: Developers hate bloated dashboards when a single search bar will do the job.
- Real-time > Batch: Showing progress indicators reduces drop-off rates significantly compared to static loader spinners.
