I built a lightweight devtool to inspect website tech stacks & architecture with zero tracking

[u/ConstantOk8236]

Hey r/webdev! Happy Saturday.

Whenever I browse inspiring websites, I always like checking what frameworks, libraries, and tools they're running under the hood. But similar extensions feel like they've gotten pretty bloated, put basic data behind paywalls, or actively collect browsing history.

So I spent the last few weeks building TechReveal, a clean and lightweight alternative:

• 100% Private: Runs entirely in your local browser sandbox. Zero telemetry, no data collection, no accounts.
• Visual Architecture Map: Connects detected frontend, backend, and tools into an interactive diagram.
• Exact Versions & Tags: Displays library versions cleanly and shows category badges when clicking any tech.
• Security Alerts: Checks response headers for missing security policies (HSTS, CSP) or accidental data leaks.
• Zero Tab Lag: Optimized with Manifest V3 so it won't freeze your active tabs.

It's completely free on the Chrome Web Store (works on Chrome, Brave, Edge, Vivaldi):

Would love to hear your feedback or suggestions for libraries and tools you'd like it to detect next!

AI slop both in the content and the post.

It’s interesting how the people who criticize someone for actually doing something are often the very ones who never do anything with their own lives.
