Why We Still Need an IDE - The JetBrains Blog

As coding agents increasingly handle multi-file tasks, dependency exploration, and refactoring, the author argues that IDEs remain essential as integrated environments for understanding project context, directing agent work, verifying changes, and maintaining accountability for shipped software. The piece compares the IDE to an aircraft cockpit: agents can execute substantial work, but engineers must still judge architectural fit, review consequences, diagnose failures, and take responsibility for decisions. It contends that IDE capabilities such as code navigation, type checking, linting, testing, and dependency analysis should support both developers and agents, grounding probabilistic AI output in deterministic validation. The author also advocates avoiding dependence on a single AI provider through interoperable standards such as the Agent Client Protocol and Bring Your Own Keys, allowing developers to select and change models without rebuilding workflows. Overall, it presents agentic development not as a replacement for engineering judgment, but as a shift from manually producing code toward defining intent, evaluating outcomes, and solving broader software problems.
