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.

RapidCopy Pro
RapidCopy serves as the portable variant of FastCopy specifically designed for Mac OS X, automatically choosing different methods based on whether the source and destination directories are located on the same or separate hard drives. It operates without utilizing the OS cache for reading and writing, ensuring that other applications maintain their performance levels. Users can experience high-speed duplicate file transfers based on either modification date or file size, along with stable copying that disregards minor errors. The software also incorporates checksum verification during file transfers and can generate detailed log files that include checksum information. It supports Linear Tape File System (LTFS) for both reading and writing, as well as various operations like synchronization, moving, and deletion, providing a multitude of copying modes. Although it boasts a straightforward interface, its functionality mirrors that of FastCopy, including the ability to perform a source and destination difference check in "Verify only" mode. Additionally, it supports multiple checksum algorithms such as xxHash, MD5, and SHA-1. It's important to note that using LTFS mode requires the installation of the LTFS driver along with an LTO device. To add files or directories to the source field easily, users can simply drag and drop them while holding down the command key, making the process quick and user-friendly. This versatility ensures that RapidCopy caters to a wide array of file management needs, enhancing user experience significantly.
