Powerfully integrate tools like JIRA, Jenkins, Team City, Bugzilla, Slack etc. Easily pluggable with any build or continuous integration system and lets your team remains in sync on test failures. Using API Mocks, your front-end team won't need any back-end API for their development. It means that your front-end team can work in parallel with the back-end teams. Apart from it's Easy-To-Use interface and Great Customer Support Team, there are some features that make vREST stand apart in its competition. Feeling lazy to write test cases? Don't Worry, in vREST you can simply record test cases by manually using your application once. vrunner lets you execute your test cases just by running a command on your terminal. So every time you deploy your application, you just need to Run a Command to validate your APIs.Starting Price: $20 per month -

RestSequence
Opcito
RestSequence is a no-code platform that allows users to create end-to-end product test workflows by using underlying product-under-test APIs. It enables users to create, manage, and execute test cases and scenarios efficiently. By harnessing the power of their application's Swagger API collection, RestSequence empowers users to quickly design and test scenarios, guaranteeing superb application performance and reliability. With RestSequence, you can onboard generated test scenarios, integrate them into your CI/CD pipeline, and run them on nightly, weekly, or release builds. The best part is that the output file generated once using RestSequence can be used for future testing scenarios without making any changes. RestSequence reads and parses API details (method, URL, payload, request body, etc.) from a Swagger specification file. It tests each API endpoint for correct responses, status codes, required fields, and invalid data, tracking the created resources during test execution. -

EthicalCheck
EthicalCheck
Submit API test requests via the UI form or invoke EthicalCheck API using cURL/Postman. Request input requires a public-facing OpenAPI Spec URL, an API authentication token valid for at least 10 mins, an active license key, and an email. EthicalCheck engine automatically creates and runs custom security tests for your APIs covering OWASP API Top 10 list Automatically removes false positives from the results, creates a custom developer-friendly report, and emails it to you. According to Gartner, APIs are the most-frequent attack vector. Hackers/bots have exploited API vulnerabilities resulting in major breaches across thousands of organizations. Only see real vulnerabilities; false positives are automatically separated. Generate enterprise-grade penetration test reports. Confidently share it with developers, customers, partners, and compliance teams. Using EthicalCheck is similar to running a private bug-bounty program.Starting Price: $99 one-time payment -

Appvance
Appvance.ai
Appvance IQ (AIQ) delivers transformational productivity gains and lower costs in both test creation and execution. For test creation, it offers both AI-driven (fully machine-generated tests) and also 3rd-generation, codeless scripting. It then executes those scripts through data-driven functional, performance, app-pen and API testing — for both web and mobile apps. AIQ’s self-healing technology gives you complete code coverage with just 10% the effort of traditional testing systems. Most importantly, AIQ finds important bugs autonomously, with little effort. No coding, scripting, logs or recording required. AIQ is easy to integrate with your current DevOps tools and processes. Appvance IQ was developed by a pioneering team who envisioned a better way to test. Their innovative vision has been made possible by applying differentiated, patented AI methods to test creation while leveraging today’s high-availability compute resources for massive levels of parallel execution. -
