When building security or code auditing tools, speed is everything. Developers won't wait 45 seconds for a bloated PDF report—they 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.

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.
