Why use Latency Lingo?

It is difficult for software teams to maintain a fast web experience while shipping new features. Small performance decreases accumulate overtime which cause a negative impact on user experience. This is more expensive to fix the longer it goes unnoticed. Thankfully, these degradations can be identified with some automation and analytics.
Latency Lingo helps teams catch these performance regressions before their users are affected by providing a continuous performance testing management and analytics product suite.
You may notice that many performance testing products lock you in by taking control of your execution. Latency Lingo is different. It integrates with your existing workflows to complement open-sourced tools rather than replace them. Take advantage of JMeter, Gatling, and k6 in your preferred environment and leverage Latency Lingo for premium test analytics and management tooling.
