RepoLens: Transforming Source Code Repositories into AI-Ready Context Packages

Overview

RepoLens is a developer tool designed to convert software repositories into structured, AI-ready context packages. It enables developers to provide complete codebase context to AI assistants such as ChatGPT, Claude, Gemini, and local models without the need for manual file copying. The tool runs entirely locally, ensuring that source code remains on the user's machine and is never uploaded to external servers.

Benefits

RepoLens addresses several challenges developers face when using AI tools with large codebases. It manages context by converting repositories with hundreds or thousands of files into optimized context packages that fit within AI model limits. The tool replaces manual file selection with automated repository scanning. Security is a primary focus as it automatically detects and masks sensitive information like API keys, access tokens, passwords, and private credentials before generating packages. This protection is enabled by default, reducing the risk of accidental exposure when sharing repository context with AI systems. The tool also provides visibility through token estimation and coverage analysis to determine if a repository fits within a target AI model's context window.

Use Cases

RepoLens is useful for several scenarios. Developers can use it for onboarding to quickly understand unfamiliar codebases by generating a context package and asking for architectural explanations. It helps create onboarding documentation or technical summaries based on the codebase. Teams can request reviews and improvement suggestions for the entire repository. It also aids in identifying architectural improvements and refactoring opportunities. Additionally, developers can investigate potential causes for specific issues within the codebase for debugging purposes.

Pricing

RepoLens is currently distributed under a proprietary license. Users should refer to the LICENSE file for specific usage terms.

Vibes

RepoLens is developed by DestLabs, a team focused on building developer tools for AI-assisted software development. The tool is designed to be secure and private, running entirely on the user's local machine without uploading source code to external servers. It supports a wide range of programming languages including Java, Kotlin, Python, Go, JavaScript, TypeScript, C#, Rust, and PHP. The tool is actively being improved with a roadmap that includes repository summaries, dependency analysis, architectural insights, additional output formats, IDE integrations, enhanced repository metadata, and AI-generated repository overviews.

Additional Information

RepoLens requires Java 21 or newer to run. Installation involves downloading the latest Repolens.jar from the project's assets section. The tool provides commands to analyze repository size and token usage, build AI-ready context packages in Pack or JSON format, scan repository content for secrets, and manage configuration values. It automatically ignores common generated and binary artifacts such as build outputs, dependency directories, archives, binaries, images, fonts, media files, and IDE or version control metadata. Users can further customize exclusions using command-line flags. The tool includes optional flags to include test files, exclude specific files or directories, generate signatures-only packages, and limit the package token count.
