Octrafic
Octrafic is an open source, AI-powered command-line tool designed for automated API testing and exploration, allowing users to interact with APIs using natural language instead of writing scripts or configuring complex testing frameworks. By pointing the tool to any HTTP API or OpenAPI specification, users can describe what they want to test in plain English, and the built-in AI agent automatically generates test scenarios, executes real HTTP requests, validates responses, and produces structured results. It handles the full testing workflow, including endpoint discovery, request construction, schema validation, and error detection, enabling developers to focus on testing logic rather than low-level implementation details. It supports real-time execution against live APIs, ensuring accurate status codes and behavior without relying on mocks, and can export results into styled PDF reports for sharing with teams or stakeholders.

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.

Requestly
Requestly API Client offers a range of tools to help you design, manage, and test APIs effectively. With distinct combination of features Requestly acts as a companion to developers and QAs.
1. Design APIs: Requestly simplifies API Design by allowing you to create individual API requests, specify HTTP methods, headers, query parameters, and request bodies.
2. Send API Requests: Sending API Requests is at the core of API testing. Responses can be viewed in detail, including status codes, headers, and payloads.
3. API Collections: Collections allow you to group related API requests for better organization and collaboration.
4. Variables: Requestly simplify API testing and management by allowing you to replace hardcoded values with placeholders - Collection, Environment, and Global Variables.
5. Scripts (Pre & Post): Scripts allow you to add logic or modify requests before they are sent, or process responses and manipulate variables that can be used in subsequent API call.
