About

Junie is JetBrains' AI coding agent, built to be cost-efficient. It plans with a powerful model and implements with a faster one, so you spend fewer tokens per task while getting the same quality. On the independent SWE-Rebench benchmark, Junie resolves more real-world coding issues than other leading agents, at a lower cost per task. Junie supports the latest models from major frontier labs on day zero, so you're never waiting on integration work to use what just shipped. It works with almost any model you choose, inside IDEs like IntelliJ IDEA, directly from the terminal, or from GitHub and GitLab issues and merge requests. A human stays in the loop. Junie asks for approval before risky actions, and you can redirect it mid-task instead of starting over. Teach Junie your team's coding standards, naming conventions, and review process, and switch from another AI coding agent in seconds with no extra setup.

About

diffray is an AI-powered code review tool that uses a coordinated multi-agent system of specialized agents to analyze your codebase deeply, understand context, and deliver focused, actionable feedback on pull requests instead of generic suggestions and style nitpicks. Unlike single-model reviewers, diffray deploys multiple expert agents across domains such as security, performance, bugs, quality, architecture, testing, and consistency to investigate, verify, and validate issues with confidence scoring, reducing false positives while surfacing real problems like vulnerabilities, concurrency issues, missing tests, and architectural anti-patterns. It integrates with GitHub via a simple setup, reviews every pull request automatically, and enforces team-defined practices as “culture as code,” giving consistent, repeatable guidance across contributors and accelerating development cycles.
