    Bruno is a developer-first, open-source API client that’s redefining what an API tool should be. Built from the ground up for speed, privacy, and simplicity, Bruno offers everything developers need to explore, test, and document APIs without the cloud lock-in, telemetry, or bloat that’s become standard elsewhere. Instead of chasing “platform” status, Bruno focuses on doing one thing exceptionally well: being a pure API client. It’s completely local... all your requests, environments, and collections stay on your machine. Nothing is uploaded or tracked. The result is a faster, safer, and more transparent workflow that developers actually enjoy using. Bruno is also Git-native, meaning collections live in plain text and can be versioned, diffed, and reviewed just like code. Branching, merging, and pull requests all just work — no proprietary formats or walled gardens. For teams that already use GitHub, GitLab, or Bitbucket, Bruno slots right in with zero friction. Under the hood, Bruno supports Postman and Swagger imports, test scripting in JavaScript, a powerful CLI, VS Code extension, and CI/CD integration for automated API testing. Since its launch in 2022, Bruno has seen explosive community growth: over 2.5 million downloads, 150,000+ daily users, and 37,000+ GitHub stars. Trusted by engineers at Microsoft, Capital One, GitHub, and FedEx, Bruno is proving that developer tools don’t need a cloud backend to scale , they just need to respect how developers actually work. In short: Bruno is what the API client should have been all along ... local, fast, Git-based, and open-source.

    Unirest Reviews
    Unirest is a collection of lightweight HTTP libraries developed and supported by Kong, the same entity that oversees the open-source API Gateway known as Kong. To get started with Unirest in a Node.js environment, you need to install the npm package. You might be curious about how Unirest simplifies the process of making requests. In addition to automatically handling gzip compression and parsing responses, Unirest offers straightforward examples to illustrate its functionality. A request can be initiated by calling the relevant method on the Unirest object, followed by the .end() function to dispatch the request. Alternatively, you can directly send the request by providing a callback alongside the URL. The library provides user-friendly methods that allow for manipulation of the request before it is dispatched. When a Unirest method is called, a request object is generated, which includes chainable methods similar to those found in libraries like jQuery and the widely-used Superagent request module, which serves as a partial model for this library. With these features, developers can enjoy a more efficient and intuitive experience when working with HTTP requests.

    You can either submit API test requests through the user interface form or trigger the EthicalCheck API using tools like cURL or Postman. To input your request, you will need a public-facing OpenAPI Specification URL, an authentication token that remains valid for a minimum of 10 minutes, an active license key, and your email address. The EthicalCheck engine autonomously generates and executes tailored security tests for your APIs based on the OWASP API Top 10 list, effectively filtering out false positives from the outcomes while producing a customized report that is easily digestible for developers, which is then sent directly to your email. As noted by Gartner, APIs represent the most common target for attacks, with hackers and automated bots exploiting vulnerabilities that have led to significant security breaches in numerous organizations. This system ensures that you only see genuine vulnerabilities, as false positives are systematically excluded from the results. Furthermore, you can produce high-quality penetration testing reports suitable for enterprise use, allowing you to share them confidently with developers, customers, partners, and compliance teams alike. Utilizing EthicalCheck can be likened to conducting a private bug-bounty program that enhances your security posture effectively. By opting for EthicalCheck, you are taking a proactive step in safeguarding your API infrastructure.

    Go REST Reviews
    Go REST is a versatile platform designed for testing and prototyping APIs that supports both GraphQL and RESTful formats, providing users with realistic fake data that mimics real responses, and is accessible around the clock through public endpoints for various entities such as users, posts, comments, and todos. This platform offers the flexibility of multiple API versions along with comprehensive search capabilities across all fields, pagination options (including page and per_page), and includes rate-limiting headers and response format negotiation to optimize performance. It adheres to standard HTTP methods, while any requests that modify data necessitate an access token, which can be provided via an HTTP Bearer token or as a query parameter. Additionally, nested resource capabilities allow for the retrieval of interconnected data, including user-specific posts, comments on posts, and todos created by users, ensuring that developers can easily access relevant information. The platform also features request and response logging, customizable rate limits, and daily data resets to maintain a pristine testing environment, facilitating a smooth development experience. Furthermore, users can take advantage of a dedicated GraphQL endpoint located at /public/v2/graphql, which enables schema-driven queries and mutations for enhanced data manipulation options.
