JetBrains Enhances Developer Tools with Claude in Amazon Bedrock to Improve Code Quality and Productivity
JetBrains, a leader in integrated development environments, improved code generation quality and developer productivity by integrating Claude in Amazon Bedrock into its IDEs and launching Junie, an AI coding agent.
Value Results Summary
JetBrains, a medium-sized software company focused on developer tools, needed to leverage generative AI to enhance its integrated development environment (IDE) offerings and make coding faster and more enjoyable for developers worldwide. After evaluating multiple large language models, JetBrains selected Claude in Amazon Bedrock for its superior performance in code-related tasks and AWS's fully managed infrastructure. Vladislav Tankov, AI Director at JetBrains, noted that Claude "consistently outperformed other models" in coding applications, achieving 100% syntactically correct code on multiple datasets. JetBrains integrated Claude across its IDE suite and into Junie, a new AI coding agent that launched in January 2025, designed to handle complex development tasks while maintaining developer control.
Claude powers three critical capabilities within JetBrains' developer tools. For documentation generation, Claude improved output quality by 19% (measured by chrF score), creating comprehensive and accurate documentation from code. For refactoring tasks, Claude increased user-driven refactoring success by 59% in terms of generating syntactically correct code, demonstrating reliability in handling developer-requested improvements. Junie's agentic workflows—such as applying GraalVM to Gradle projects—leverage Claude's ability to handle notoriously complex scenarios. Junie follows a four-step workflow that balances automation with developer oversight: task assignment, project exploration, solution proposal, and task execution with testing.
The integration has delivered measurable impact on developer productivity and experience. Junie achieves 53%+ task completion success, placing it among top-tier AI coding agents in industry benchmarks. By automating routine tasks, refactoring code, and generating test cases, Junie allows developers to focus on creative problem-solving while reducing "blank page syndrome" on new projects. Customer demand validated the decision—some developers directly requested Claude integration through LinkedIn—and JetBrains continues leveraging Claude's capabilities through Amazon Bedrock's robust infrastructure to transform how software is built, combining AI automation with human creativity.
