		Related Products JetBrains Junie 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.

Pros & Cons from Real Users Pros As a junior developer, I’ve had the chance to experiment with Claude Code, and I must say it has truly exceeded my expectations. The learning curve is minimal, and the interface is user-friendly, which is a big plus for someone like me just starting out. Claude Code's ability to generate clean, well-structured code is impressive. It helps me understand how to implement best practices and is a great learning tool. The suggestions it gives are often on-point and relevant, saving me time when I’m stuck or looking for an efficient solution. The integration with popular frameworks and languages makes it very versatile. The speed of responses is another big advantage. It’s fast enough to keep me in the flow, allowing me to focus more on problem-solving rather than waiting for solutions. Cons While Claude Code is great for most tasks, there are times when its suggestions can be a bit too generic, and I have to tweak them to fit my project’s specific needs. It’s also not perfect when it comes to edge cases, and there have been times where I’ve needed to double-check its output. Sometimes, the documentation or explanations behind the code could be more detailed, especially for more complex problems. As a junior developer, understanding why certain code works is just as important as the code itself.	Pros & Cons from Real Users Pros Codex CLI is great because it brings OpenAI’s coding agent directly into the terminal. I like that it fits into a normal developer workflow instead of forcing everything through a separate web app or IDE extension. It can read, modify, and work with code locally, which makes it useful for debugging, refactoring, exploring a repo, and handling coding tasks without leaving the command line. That is especially nice for developers who already live in terminal-first workflows. I also like that it is part of the broader Codex ecosystem. If I want the same general agent experience in an IDE, desktop app, or ChatGPT’s cloud-based Codex, there are options for that too. Cons I would still supervise it closely. Any AI coding agent that can touch local files and interact with a dev environment needs review, tests, and clear boundaries. It can also run into the usual coding-agent issues: setup problems, API/config errors, terminal quirks, command failures, and tool-use mistakes. A recent empirical study of Claude Code, Codex, and Gemini CLI found that many reported bugs in these tools involve functionality, integrations, configuration, terminal behavior, and command execution.
