    Go REST

    Go REST

    Go REST

    Go REST is a GraphQL and RESTful API platform for testing and prototyping that delivers fake data with real responses, available 24/7 via public endpoints for users, posts, comments, and todos. It supports multiple API versions with full search on all fields, pagination (page and per_page), rate-limiting headers, and response format negotiation. Standard HTTP verbs are supported, and mutating requests require an access token via HTTP Bearer or query parameter. Nested resources let you retrieve related data, user posts, post comments, and user todos, while request and response logging, customizable rate limit,s and daily data resets ensure a clean testing environment. A GraphQL endpoint at /public/v2/graphql offers schema-driven queries and mutations.

    ITRS Load Testing
    Ensure scalability on websites, apps and APIs. For the always-on enterprise. Control the ramp and bandwidth of over thousands of global virtual users and simulate real-world dynamics. Integrate with AppDynamics, New Relic, and Dynatrace to drill down, pinpoint critical issues, and identify root-cause. Measure the quality of user experience by viewing a stream of real browser render times and screenshots while tests run. Get feedback in real time, adjust parameters on the fly, and find optimal concurrency, breakage points and peaks. Consumer expectations are at an all-time high. Users demand a near instantaneous experience across all devices, and at all times. To compound this, business and IT leaders recognizes their mission-critical application stack is growing and becoming increasingly complex. When sluggish response times, performance bottlenecks, and full-blown website and application failures drive visitors away, the end result is lost revenue and reputational damage.

    Levo.ai

    Levo.ai

    Levo.ai

    Levo.ai gives enterprises unparalleled visibility into their APIs while continuously discovering and documenting internal, external and partner/third-party APIs. Enterprises can then see the risk from their apps and prioritize it based on the sensitive data flows, AuthN/AuthZ usage and several other criteria. Levo.ai then continuously security tests all apps and APIs to find vulnerabilities in the SDLC as early as possible.

    Equixly

    Equixly

    Equixly

    Equixly aims to help developers and organizations create secure applications, increase their security posture, and spread knowledge of new vulnerabilities. Equixly makes available a SaaS platform that allows integrating the API security testing within the software development lifecycle (SLDC) to detect flaws, reduce bug-fixing costs and exponentially scale penetration testing upon every new functionality released. The platform can automatically perform several API attacks leveraging a novel machine learning (ML) algorithm trained over thousands of security tests. Then, Equixly returns near-real-time results and a predictive remediation plan that developers may use to fix their application issues autonomously. The Equixly advanced platform and its innovative security testing approach take an organization's API security maturity to the next level.
