Project Update
TLS Viewer started as a tiny personal side project — something built simply to experiment with certificate inspection. It quickly grew far beyond expectations and became a go-to tool for developers, security researchers, sysadmins, and IT professionals who needed a fast, reliable way to examine TLS/SSL certificate chains.
Because of this unexpected growth, a complete rebuild is now underway.
What’s Coming
- TLS Engine — a new backend designed to be faster, more reliable, and significantly more accurate.
- A fully redesigned frontend with improved performance, cleaner layout, and better usability.
- All existing features will remain available throughout the transition, with no planned downtime.
Development progress will be shared on X at @tlsviewer.
Thank you for using TLS Viewer and for all the feedback that made this upgrade possible. The new version is coming soon.
