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.

JetBrains Junie is an innovative AI coding assistant that works inside many JetBrains IDEs to streamline programming efforts and boost efficiency. This agent leverages advanced AI to help developers write, test, and inspect code without leaving their familiar development environment. Junie offers both code execution and interactive collaboration, allowing programmers to switch between automated code writing and brainstorming sessions for features and improvements. By deeply understanding the codebase, Junie identifies the best ways to tackle tasks and ensures all changes meet quality standards through syntax and semantic checks. It also runs tests to minimize errors and keep the project healthy, freeing developers from routine tasks. Many developers have successfully built complex applications and games using Junie, highlighting its flexibility across different languages and frameworks. The AI adapts to each task’s complexity and workflow, making coding less tedious and more focused on creativity. Whether you are building a simple web app or a complex game, Junie offers smart support throughout the development cycle.

Z/XDC
Z/XDC offers developers an interactive and source-level debugging experience for mainframe programs within any z/OS environment, enabling them to navigate through live code, monitor variables in real-time, and address issues more swiftly than conventional techniques allow. By eliminating the guesswork inherent in traditional debugging, it grants comprehensive, real-time insight into program execution and introduces advanced debugging features to mainframe development. With Z/XDC, developers can significantly cut down on debugging durations, transforming a process that typically takes days into one that can be accomplished in hours, allowing them to test hypotheses instantly without the need for lengthy recompilation, make spontaneous modifications, run “what if” scenarios, correct problems, and validate solutions efficiently. Among its capabilities, Z/XDC allows for precise line-by-line stepping through code, instant code alterations, flag adjustments, modifications of data fields and registers, control over the Program Status Word (PSW), and the ability to load or delete modules, as well as manage memory with GETMAINs and FREEMAINs, and post Event Control Blocks. Additionally, it ensures source-level visibility, allowing developers to view the code as initially written, automatically load source image maps from ADATA, and access a variety of other helpful features, making it an indispensable tool for modern mainframe programming. This integration of advanced debugging functionalities enhances overall productivity and streamlines the development workflow for programmers working in mainframe environments.
