Checksum.ai
Checksum.ai
Checksum is a continuous quality platform that autonomously generates, runs, and maintains tests so engineering teams can ship AI-generated code without trading speed for reliability. Unlike copilots that wait for prompts, Checksum works as a background agent, detecting what needs testing, generating production-ready Playwright, and healing broken tests automatically. Seventy percent of failures resolve autonomously, keeping suites green without manual effort. Built on fine-tuned data from 1.5+ million test runs, Checksum covers every layer of the SDLC: end-to-end, API, and CI testing from a single platform. Tests are delivered as standard Playwright code, submitted as a PR to your repo. No vendor lock-in. Checksum integrates natively with Cursor, Claude Code, and 100+ coding agents via /checksum slash commands, so code is tested before a human ever reviews it. AI handles generation and healing on Checksum's cloud: no LLM tokens. The result: ship faster, with confidence. -

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. -
