"APIs are the backbone of the apps and web services that run the world, yet most companies don’t have a true understanding of their functional uptime and reliability. Sauce Labs collects those insights by leveraging functional and integration tests as monitors. This provides a single source of truth for uptime and detailed reporting for when problems occur with functionality or performance. With PagerDuty, Sauce Labs' users gain granular control over notifications to ensure compliance with company policies while centralizing test and incident response processes among developers, testers, and product owners.
