Plandex

Supporting context windows of up to 2 million tokens, Plandex can work effectively across entire codebases rather than just individual files or functionsmaking it practical for feature development, refactoring, debugging, and modernization tasks that require understanding and modifying code spread across dozens of files simultaneously.

The platform offers configurable autonomy across a spectrum from full automatic execution to fine-grained human approval at each step.

In full auto mode, Plandex executes multi-step development plans without pausing for confirmationcompleting long tasks efficiently for situations where the developer trusts the direction.

When more control is needed, the diff review sandbox allows users to inspect every proposed change before any file is actually modified, with version control and branching so that different implementation approaches can be compared and alternative paths explored before committing.

Automated debugging capabilities extend to terminal command execution: Plandex can run build processes, linters, test suites, and deployment scripts, analyze the output when errors occur, and iteratively debug the issuescycling through the run-analyze-fix loop autonomously until the command succeeds or the agent determines it needs human input.

For browser applications, Chrome integration enables automatic identification and debugging of frontend issues visible in the browser environment.

Project-awareness is maintained through fast project map generation using tree-sitter, which builds a syntax-aware understanding of the codebase structure across 30+ programming languages.
