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.

In today’s fast-evolving technological landscape, a groundbreaking strategy for testing is essential. Empower your teams with advanced tools that foster the creation of adaptable and scalable tests designed for cloud environments. With the use of the intelligent agent (Architect), you can quickly generate AI-enhanced tests, or you can convert instructions written in straightforward English into automated workflows using natural language processing. This approach eliminates the persistent issue of having to fix broken tests. Functionize harnesses machine learning technology to automatically modify your tests in response to any changes in the user interface. Quickly identify test failures with immediate SmartFix suggestions, and utilize screenshot comparisons alongside clear error messages to facilitate easy troubleshooting. Interact with your tests in real time on a virtual machine by using breakpoints in conjunction with Live Debug capabilities. Modify your tests with ease through Smart Screenshots, taking advantage of one-click SmartFix solutions. Additionally, relieve your team from the complexities of test infrastructure management. Functionize’s Test Cloud allows you to run an unlimited number of tests regularly across all major browsers at scale, ensuring that your testing process is both nimble and effective. This cutting-edge approach not only boosts productivity significantly but also contributes to superior quality in software development, ultimately leading to more reliable applications. As a result, teams can focus their efforts on innovation rather than getting bogged down by testing challenges.
