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.

axe DevTools
Axe DevTools offers exceptional precision in evaluating the accessibility of pages and components during development, leveraging a rules engine that aligns with the Web Content Accessibility Guidelines (WCAG). The browser extension independently identifies 57% of accessibility issues, and with the help of Intelligent Guided Testing (IGT), developers can resolve 80% or more of these problems without requiring any extra training. This innovative tool elevates accessible coding to new heights, starting with a complimentary Chrome extension and the axe Linter.
By automating digital accessibility, Axe DevTools equips developers with the most comprehensive testing resources available, ultimately conserving time, money, and effort for development teams. The integration of automated intelligence streamlines the process, as our computer vision technology ensures greater accessibility coverage in a variety of settings more quickly than competing tools.
From the initial scan, Axe DevTools seamlessly integrates into your development workflow with just a single command in your build process. The tool proves that accessibility can work in harmony with fast-paced release cycles, guiding users on where to begin, assessing their impact, identifying remaining areas for testing, and allowing them to track progress over time.
As digital asset patterns and trends evolve continuously, our AI-driven data pipeline ensures you remain at the forefront by providing real-time insights from thousands of actual users, making it an indispensable resource for developers committed to accessibility.
