Junie, the AI coding agent by JetBrains, revolutionizes the way developers interact with their code by embedding intelligent assistance directly into JetBrains IDEs like WebStorm, RubyMine, and GoLand. Designed to fit naturally into developers’ existing workflows, Junie helps tackle both small and ambitious coding tasks by providing tailored execution plans and automated code generation. It combines the power of AI with IDE capabilities to perform code inspections, syntax checks, and run tests automatically, maintaining code quality without manual intervention. Junie offers two distinct modes: one for executing code tasks and another for interactive querying and planning, allowing developers to seamlessly collaborate with the agent. Its ability to comprehend code relationships and project logic enables it to propose efficient solutions and reduce time spent on debugging. Developers from various fields, including game development and web design, have showcased impressive projects built entirely or partly with Junie’s assistance. The tool supports multi-file edits and integrates version control system (VCS) assistance, making complex refactoring easier and safer. JetBrains offers multiple pricing plans tailored to individuals and organizations, ranging from free tiers to premium AI Ultimate for intensive daily use. By handling repetitive coding chores, Junie frees developers to focus on the creative and strategic aspects of software development. Overall, Junie stands as a powerful AI companion transforming traditional coding into a smarter, more collaborative experience.

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.

IBM Developer for z/OS
IBM Developer for z/OS Enterprise Edition is a modern enterprise development platform designed to help organizations accelerate application development, modernization, and DevOps adoption on IBM z/OS systems. The solution combines Eclipse-based tools, Visual Studio Code integration, browser-based development environments, and advanced debugging capabilities into a unified toolset for enterprise mainframe development. It supports a wide range of programming languages and technologies including COBOL, PL/I, High Level Assembler, REXX, Java, JCL, C/C++, and other z/OS development frameworks. The platform is built to help organizations modernize traditional mainframe workflows while integrating industry-standard DevOps practices such as Git-based source control, CI/CD pipelines, automated builds, and cloud-enabled collaboration. Developers can work within familiar interfaces like Eclipse, VS Code, or browser-based environments depending on their workflow preferences and team requirements. IBM Developer for z/OS Enterprise Edition includes advanced debugging capabilities that support full-context debugging across Eclipse, VS Code, and 3270 environments, giving developers flexible troubleshooting options for complex enterprise applications. The platform also features intelligent development tools such as smart code navigation, syntax validation, control flow diagrams, data flow analysis, and ISPF-style interfaces to improve productivity and code understanding. Security and quality assurance are strengthened through integrated tools like ZCodeScan, which identifies vulnerabilities and performs code reviews across z/OS applications. Code coverage analysis tools help teams measure application testing completeness and understand runtime behavior across executable code paths.

Z/XDC
Z/XDC provides developers with a dynamic and source-level debugging platform for mainframe applications in any z/OS setting, allowing them to traverse live code, observe variable changes in real-time, and resolve issues more efficiently than traditional methods permit. By removing the uncertainty associated with conventional debugging practices, it offers deep, real-time insights into program execution while introducing innovative debugging features tailored for mainframe development. Developers using Z/XDC can drastically reduce the time spent on debugging, transforming a process that usually spans several days into one that can be completed within hours, which empowers them to instantly test hypotheses without the delays of extensive recompilation, make on-the-fly adjustments, conduct “what if” analyses, rectify issues, and efficiently validate solutions. Among its extensive features, Z/XDC enables developers to execute precise line-by-line navigation through code, make immediate code modifications, alter flags, adjust data fields and registers, control the Program Status Word (PSW), load or remove modules, and manage memory through GETMAINs and FREEMAINs, along with posting Event Control Blocks. Moreover, it guarantees source-level visibility by allowing developers to view the code in its original form, automatically retrieve source image maps from ADATA, and utilize a myriad of additional beneficial features, thus establishing itself as an essential asset for contemporary mainframe programming. This incorporation of sophisticated debugging functionalities not only boosts overall productivity but also refines the development process for programmers engaging in mainframe environments, ultimately leading to a more streamlined and effective workflow. In essence, Z/XDC redefines the debugging landscape for mainframe applications, making it a crucial tool for developers striving for efficiency and accuracy.
