In their words
“In my opinion, with your speed, quality, reliability, and constant development, you simply do not have real competitors. Your announcement feed is the fastest and most reliable one I have seen.”
“I hope you will always be there. I am willing to keep paying for your professional services. It is extremely valuable.”
“I’ve been testing the SpeedTrial for the past few days and measuring the latency of the announcements. I’m very happy with the performance so far.”
“I’ve really enjoyed testing your service over the past few days, and the latency measurements have been very impressive.”
“Thank you for your service. It was very fast.”
The numbers behind the badges
The figures above are measured, not marketing: more than 20,000 announcement messages delivered to subscribers since April 2026, counted directly from our production dispatch log, and >99.99% uptime across our Tokyo and Seoul endpoints with 24/7 monitoring.
Where these reviews come from
Every quote on this page is a verbatim message we received from a subscriber, reproduced unedited and anonymized. We do not run incentivized review campaigns.
You don’t have to take their word for it. The free SpeedTrial tier streams the production feed with zero added delay and microsecond timestamps on every event, so you can measure our latency yourself before paying anything.
