Runscope
Runscope
An API Monitoring (Runscope) API test is a group of one or more HTTP requests executed sequentially to evaluate the uptime, performance and correctness of an API. For each step in the test, you can define Assertions to validate response data and Variables to extract data to be used in subsequent requests. A test Passes if all the assertions pass. A test Fails if any assertion fails, or another error is encountered, such as a network connection problem. Your customers shouldn’t be the ones telling you about downtime and breakages. Runscope supports the notification tools you already use, like PagerDuty, Slack, HipChat, email, webhooks and more. Proactively monitor service performance to quickly catch and debug API problems fast. Stay ahead of intermittent failures before they become major issues with the API Dashboard and daily API Performance Report. Verify that the structure and content of your API calls meets your expectations. Powerful and flexible assertions give you total control. -

BoxWatch
BoxWatch
BoxWatch is server monitoring that does the job of four tools at once: metrics, cron heartbeats, uptime checks, and process monitoring. One agent, one dashboard, one bill. Most teams stitch together Datadog (or similar) for metrics, Healthchecks.io for cron, UptimeRobot for HTTP checks, and a separate supervisor for processes. BoxWatch replaces all of that. Metrics: CPU, memory, disk, network, load, and uptime, collected by a small open-source bash agent installed with one curl command. Trend charts, side-by-side comparison views, and disk-full prediction that warns you days before a volume actually fills. Cron heartbeats: ping a URL when a job finishes, get alerted when the ping is late or missing. Four alert types with transition-based dedup so you never get spammed. Uptime checks: HTTP, TCP, and TLS-expiry probes executed by your own deployed BoxWatch agents.Starting Price: $0 -
