Checksum.ai
Engineering teams shipping with AI have a new bottleneck: validation. Code output has accelerated. Quality hasn't. Checksum closes the gap.
Checksum is a continuous quality platform with a suite of AI agents that handle testing end-to-end, at every stage of the development lifecycle. Where most tools wait for a human to trigger them, Checksum runs autonomously in the background, generating tests, executing them, and repairing failures without manual intervention. Seventy percent of test failures are resolved automatically through real-time auto-recovery.
The platform covers every layer: end-to-end UI flows via Playwright, API endpoint chains, and targeted CI tests scoped to exactly what changed in a PR. All tests land as real code in your repository and are delivered as standard Playwright, owned by your team.
Checksum is fine-tuned on 1.5+ million test runs and integrates natively with Cursor, Claude Code, and 100+ AI coding agents. Type /checksum and your coding agent's output gets tested before it ever reaches review. Generation and healing happen on Checksum's cloud infrastructure which means no LLM tokens consumed, no local resources required.
The result: test suites that stay green as the product evolves, fewer regressions reaching production, and release confidence that scales alongside AI output.

MuukTest
You know that you could be testing more to catch bugs earlier, but QA testing can take a lot of time, effort and resources to do it right. MuukTest can get growing engineering teams up to 95% coverage of end-to-end tests in just 3 months.
Our QA experts create, manage, maintain, and update E2E tests on the MuukTest Platform for your web, API, and mobile apps at record speed. We begin exploratory and negative tests after achieving 100% regression coverage within 8 weeks to uncover bugs and increase coverage. The time you spend on development is reduced by managing your testing frameworks, scripts, libraries and maintenance.
We also proactively identify flaky tests and false test results to ensure the accuracy of your tests. Early and frequent testing allows you to detect errors in the early stages your development lifecycle. This reduces the burden of technical debt later on.

LibreSpeed
Introducing a self-hosted Speedtest solution that utilizes HTML5 among other technologies, designed for straightforward installation and configuration, with a mobile-responsive design. This lightweight Speedtest is crafted in Javascript, leveraging XMLHttpRequest and Web Workers, ensuring compatibility with all modern browsers, including IE11, Edge, Chrome, Firefox, and Safari, as well as their mobile counterparts. The setup requires a reasonably fast web server like Apache 2, although options like Nginx and IIS are also viable. It runs on PHP 5.4, but other backend solutions are available, and can connect to a MySQL database to store test results, with PostgreSQL and SQLite as additional options. A template is provided for developing an Android client tailored for your LibreSpeed setup, and you can find a Docker image on Docker Hub for easy deployment. Furthermore, a partial Node.js implementation can be accessed in the node branch, offering various features such as IP Address tracking, ISP identification, server distance measurements, optional telemetry, results sharing, and the ability to perform multiple test points for comprehensive analysis. This solution is ideal for those seeking flexibility and control over their internet speed testing needs.
