AI coding tools have fundamentally changed how software gets built. Developers are shipping more code, faster, with less friction than ever before. But the organizations benefiting most from AI-accelerated development are running into the same wall: quality hasn't kept pace.
More code means more surface area for bugs. More PRs means more review burden on senior engineers. More releases means more chances for regressions to reach customers. The bottleneck has moved from writing code to verifying it, and verification is still largely manual.
Checksum is a continuous quality platform built for this reality. Its suite of AI agents autonomously generates, runs, and maintains tests across every layer of the software development lifecycle: end-to-end UI flows, API endpoint coverage, and PR-level CI validation, so engineering teams can move fast without sacrificing reliability.
What sets Checksum apart: it doesn't wait for instructions. It works as a background agent, continuously monitoring your codebase, generating tests for what matters, and repairing broken tests as the product evolves. Seventy percent of test failures resolve automatically, eliminating the maintenance burden that causes most test suites to decay and get abandoned.
Every test Checksum produces is real, Playwright code you own, submitted as a PR to your repository. No vendor lock-in. Teams keep full control.
Checksum is fine-tuned on 1.5+ million test runs and integrates natively with Cursor, Claude Code, and 100+ AI coding agents via /checksum slash commands. Testing happens before code review, not after. Generation and healing run on Checksum's cloud, consuming no LLM tokens or local resources.
The bottom line: Checksum gives engineering teams the confidence to ship at the speed AI makes possible.

It's clear that enhancing your testing efforts could help identify bugs sooner, yet effective QA testing often demands significant time, effort, and resources. With MuukTest, engineering teams can achieve up to 95% coverage of end-to-end tests in a mere three months.
Our team of QA specialists is dedicated to creating, overseeing, maintaining, and updating E2E tests on the MuukTest Platform for your web, API, and mobile applications with unparalleled speed. After reaching 100% regression coverage within just eight weeks, we initiate exploratory and negative testing to discover bugs and further elevate your testing coverage. By managing your testing frameworks, scripts, libraries, and maintenance, we significantly reduce the time you spend on development.
Additionally, we take a proactive approach to identify flaky tests and false results, ensuring that your testing process remains accurate. Consistently conducting early and frequent tests enables you to catch errors during the initial phases of the development lifecycle, thus minimizing the burden of technical debt in the future. By streamlining your testing processes, you can improve overall product quality and enhance team productivity.

HttpMaster
HttpMaster is a specialized tool designed for debugging and testing HTTP requests, particularly for web API applications and RESTful web services.
Key features include the ability to create HttpMaster projects that encapsulate the full definition of request items. It offers a wide range of HTTP properties such as headers and URL encoding to ensure thorough testing. Users can leverage dynamic parameters to mimic different input scenarios or establish global API values for consistency. The tool also allows for response data validation using logical expressions, which enhances the accuracy of testing outcomes. Additionally, request chaining enables users to carry over data from one request to the next, facilitating more complex testing scenarios. HttpMaster supports extensive data upload options, including formats like 'multipart/form-data', which is crucial for testing file uploads. Furthermore, it includes a request data builder that allows users to customize the request body with optional parameters, enhancing flexibility. Users can monitor the execution of request items in detail and can organize requests into execution groups for batch processing. The tool also features a comprehensive review and management system for execution data, making it easier to analyze results. Ad-hoc execution is simplified with a basic request tool, and a command line interface is provided for automation purposes. Finally, HttpMaster supports generating PDF reports and executing cURL commands, making it a versatile choice for developers and testers alike.
