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.

pexpect
Pexpect significantly enhances Python's capabilities for managing other applications. This library, written entirely in Python, is adept at creating child processes, managing them, and responding to specific output patterns. Much like Don Libes’ Expect, Pexpect enables scripts to communicate with child applications as though a user were manually inputting commands. It proves especially beneficial for automating the management of interactive applications such as ssh, FTP, passwd, and telnet. Moreover, Pexpect simplifies the automation of setup scripts, allowing for the efficient replication of software installations across multiple servers. This tool is also instrumental in performing automated software testing, making it a versatile asset in various programming environments. While Pexpect draws inspiration from the concepts of Expect, its complete implementation in Python differentiates it from other similar libraries. Importantly, Pexpect does not require TCL or Expect, nor does it need the compilation of C extensions, which enhances its adaptability across any system that supports Python's standard pty module. The straightforward design of the Pexpect interface makes it highly accessible for developers, ensuring that even those with minimal experience can utilize its features effectively. In summary, Pexpect emerges as a powerful solution for automating and managing a wide range of applications with ease and efficiency.

websockets
The websockets library provides a thorough implementation of the WebSocket Protocol (RFC 6455 & 7692) suitable for developing both WebSocket servers and clients in Python, with a focus on precision, ease of use, resilience, and optimal performance. By leveraging asyncio, Python’s native asynchronous I/O framework, it offers an advanced coroutine-based API that simplifies the development process. The library has been rigorously tested to align with the standards set forth in RFC 6455, and its continuous integration process ensures that every branch maintains 100% code coverage. Specifically tailored for production use, websockets was the pioneering library to effectively tackle backpressure challenges before they became widely recognized in the Python community. Additionally, it features optimized memory management and employs a C extension to boost performance for high-demand tasks. The library is readily available in pre-compiled formats for Linux, macOS, and Windows, distributed as wheels suited for each system and Python version. With websockets catering to the complex technical aspects, developers can focus on creating reliable applications without being bogged down by the underlying intricacies. This positions it as an invaluable resource for developers aiming to fully exploit the advantages of WebSocket technology, ultimately enhancing the development experience and efficiency.
