Take observability to the next level
Traditional observability solutions tell you when and where a problem might be occurring in your API. But only Speedscale can tell you why it happened. Augment your observability efforts with direct payload visibility provided by Speedscale, and get to the root cause of the issue faster and with a higher degree of certainty.
Troubleshoot faster
Diagnose root causes by inspecting transaction details, payloads, headers, and Kubernetes metadata.
Uncover blindspots
See exactly what users do, not just endpoints they hit, to detect unusual behavior quickly.
Map dependencies
Automatically detect inbound and outbound transactions for real-time dependency mapping.
Save costs
Monitor non-prod environments at a fraction of the cost of traditional tools.
Real-life issues detected with Speedscale
Health Check Bug
A national home improvement retailer found a bug in their staging environment that was repeatedly "health checking" an API hundreds of times per second. Had it been deployed to production, it would have likely caused an outage.
Cost Savings
A fast food restaurant chain saved several thousand dollars on cloud costs by identifying and fixing five-year-old code that had been polling an API 8 times per second.
Security Risk
A mobile phone provider noticed that one of their test environments was connected to a production database. This could have led to data corruption or GDPR violations.

Customer Success Story
Cimpress finds hidden issues in their app, thanks to Speedscale
"In one instance, I noticed that there was a small amount of traffic that had been causing some failures in our system. It was only happening 3% of the time, but it was still somehow critical to how it all worked. So, I went in and fixed it, but I wouldn't have found that issue had I not seen it in Speedscale."
- Jeff Kwan, Principal Software Engineer, Cimpress
