Performance, SLAs and more

Measure latency, network effects, uptime, quality and more with fully integrated performance management & SLAs.

Easy setup, simple import

Set it up with our call creator or sync collections direct from your API documentation via Postman, OpenAPI, and more

“It’s really good … I see everything very quickly on one page and it makes it really easy to go to a problem spot and dig in.  Just the other day, we had a single, random incident where one of our APIs flagged a content error, and the whole system made it easy to capture what was needed for the engineers to go do some detailed examination.”

Val Novikov, CTO, FiSpan

Your users don’t access the same cloud. Why monitor from just one?

It’s a world of containers and serverless architectures. You have little visibility on where your customers and partners are. You can’t risk only doing REST API testing from a single cloud service.

With APImetrics, you don’t have to compromise. 80+ locations on public cloud locations around the world. A dynamic scheduling engine that allows you to set call frequencies and even downtime. Don’t be limited to AWS simply because that’s what someone picked as their platform – see how your critical REST API testing responds to calls from anywhere in the public cloud and identify the best options for your solution and users.

Intelligent Scheduling

Our intelligent scheduler does the work for you. Your APIs are exercised randomly from the locations you pick, giving you full coverage and confidence in performance.

Downtime Manager

Avoid being hit with errors or SLA issues when you expect to be down. Schedule downtime for your APIs. We even provide an API to automatically integrate downtime from other developer tools.

Go straight from test cases to global functional monitoring and SLA delivery

Schedule REST API testing to run from any of our cloud locations at the click of a button. Generate shareable performance metrics and reports. No extra configuration or busy work.

Hand your monitoring over to other teams like customer success, business analysts, and the C suite without any additional hoops.
