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.

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.

SpeedTest Master
The Internet Bandwidth Speed Test serves as a reliable tool for measuring the speed of various internet connections, including WiFi and mobile networks like 2G, 3G, and 4G, as well as DSL and ADSL. With a simple tap, users can receive precise speed test results in under 30 seconds, allowing them to assess download and upload speeds, as well as ping. A real-time graph visualizes the internet speed performance, aided by thousands of global servers to enhance testing efficiency. This application also functions as a WiFi analyzer, capable of evaluating your WiFi connection quality. You can monitor download and upload speeds, along with latency and jitter, and it automatically diagnoses network issues if a poor connection is detected. Additionally, it identifies unauthorized devices connected to your WiFi network. Users receive comprehensive speed test details and real-time graphs that indicate connection status, making Speed Test Master a valuable resource for millions around the globe who want to verify whether their internet service provider delivers the promised speeds. By utilizing this app, individuals can make informed decisions about their internet service and troubleshoot any connectivity problems effectively.

Speedtest Pro
You can directly assess your network from the toolbar and swiftly evaluate your internet performance with a single click. This testing tool offers insights into the user's network condition from various perspectives. Speedtest Pro serves as a high-quality speed testing solution, enabling users to easily identify the root causes of connectivity issues. It measures and displays the ping value in seconds, allowing for the testing of both download and upload speeds. In addition, it evaluates the loading speed of the current webpage. By accessing advanced options, you can choose whether to include the webpage loading speed in your tests. This measurement reflects the time taken for data sent from your computer to reach the web server and for the server to respond. Typically, this is represented by the level of network delay experienced in online gaming, where a higher ping value indicates greater delays and can affect gameplay smoothness. Upstream traffic refers to the amount of network data transmitted within a given time frame. It's important to note that standard broadband connections often have unequal upstream and downstream speeds, with upstream bandwidth frequently subject to limits. Moreover, understanding these metrics can greatly enhance your online experience and help optimize your network usage.
