StatusDrift
ApptlySoft
StatusDrift is an uptime monitoring platform that watches your websites, APIs and infrastructure around the clock and alerts you the instant something drifts. Set up monitors in seconds with support for HTTP, HTTPS, ping, TCP port, SSL certificate expiry and keyword checks, all running from multiple regions so you can distinguish a real outage from a local blip. When a problem is detected, StatusDrift opens an incident automatically and gives you a full timeline - which regions were affected, how response times changed, and how long the issue lasted. You can acknowledge, investigate and resolve incidents right from your phone. Plan maintenance windows ahead of time so alerts stay quiet and your team knows exactly what's happening. The dashboard rolls up everything into a single view: monitors up, down, warning, paused or with expiring certificates, plus your latest incidents.Starting Price: $9/month -

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. -

Larm
Larm
Larm is an uptime monitoring platform that checks websites, APIs, and services from multiple global locations and only alerts you when multiple probes confirm a problem. This multi-location verification eliminates the false positives that plague most monitoring tools. Larm supports HTTP, TCP, DNS, SSL certificate, and heartbeat/cron monitoring. Every HTTP check captures a full request waterfall (DNS, TCP, TLS, TTFB, transfer), giving you the data you need to debug performance issues, not just know something is down. Status pages are included on every tier, including the free plan. Pages are rendered as static HTML and served from a CDN, so they stay up even when your infrastructure doesn't. Custom domains, email subscribers, automated incident updates, and component grouping are supported on paid plans. Alerts can be sent through 13+ channels.Starting Price: $19/month -
