- (2025-03-10) Jorge Carrion Lopez: The only tool capable of doing a complete debug of what is going on in your gtmss. Essential
- (2025-03-07) Daniel Dudek: There is no extension on the market that can do this. I find incredible its functionality and simplicity to be able to debug the requests or calls from the different client providers that have GTM Server Side installed.
- (2025-03-07) Guillem Ferrer: Amazing tool.. there's nothing else in the market to check what's happening with the GTM server-side and debug it, this is like the Google Tag Assistant but for the sGTM.
