Introduction
AI coding assistants are evolving fast, but most still miss the bigger picture. Codebuff, an open-source AI coding agent, changes that by using a team of specialized agents to understand your entire project. The result? Smarter workflows, cleaner edits, and performance that even outpaced Claude Code in more than 175 coding tasks.
Instead of relying on one big model, Codebuff uses a team of specialized agents that collaborate to understand your project and deliver precise edits. It’s fast, customizable, and best of all—100% open source.
What Is Codebuff?
At its core, Codebuff is a multi-agent AI coding system. Traditional tools often struggle with large projects because they treat code as isolated snippets. Codebuff, on the other hand, indexes your entire project in seconds, maps the architecture, and keeps a running memory in a human-readable knowledge.md file.
This lets Codebuff learn and improve over time, becoming smarter with each session.
Key Features of Codebuff
1. Deep Customizability
You can build sophisticated workflows with TypeScript generators that blend AI with programmatic control. Whether you’re writing scripts, automating refactors, or testing changes, Codebuff adapts to your style.
2. Use Any Model via OpenRouter
Unlike other tools that lock you into a single model, Codebuff supports Claude, GPT, Qwen, DeepSeek, and more. You get to pick the AI model that fits your needs.
3. Reusable Agents
Compose and reuse published agents to accelerate your projects. Instead of starting from scratch, you can stitch together existing agents for faster results.
4. Terminal-First Experience
Codebuff was designed for developers who love the CLI. With a simple install (npm install -g codebuff), you can run commands like:
codebuff "Add authentication to my API"
It scans the project, edits files, and even runs tests—all without extra setup.
5. Full SDK Access
Beyond the CLI, developers can integrate Codebuff directly into applications through its SDK. That makes it more than a coding assistant—it’s a development partner.
How Codebuff’s Specialized Agents Work
The real magic lies in its multi-agent system:
- File Explorer Agent → Maps your project structure.
- Planner Agent → Decides which files to modify and in what order.
- Implementation Agent → Applies precise edits across files.
- Review Agent → Validates edits for consistency and runs checks.
Together, these agents behave like a mini development team, delivering context-aware, reliable results.
Performance: Outpacing Claude Code
Benchmarks show Codebuff’s 61% success rate vs. Claude Code’s 53% across 175+ coding tasks. That’s not just a small bump—it’s proof that breaking down coding into specialized roles produces fewer errors and smarter edits.
Developers also report faster indexing and more trustworthy code suggestions. Git integration and an “undo” command make it safe to experiment, even when Codebuff runs commands like installs or tests.

Why Developers Love Codebuff
- Accuracy: Fewer mistakes with specialized agents.
- Speed: Indexes large projects in seconds.
- Flexibility: Works with any AI model you prefer.
- Learning: Builds long-term memory via
knowledge.md. - Openness: Fully open source with an active community.
For many, Codebuff isn’t just a tool—it feels like working with a real coding teammate.
Final Thoughts
Codebuff proves that the future of coding AI lies in multi-agent collaboration. With its customizable workflows, open-source foundation, and superior benchmarks, it’s already a step ahead of traditional single-model tools like Claude Code.
If you’re a developer looking for an AI coding partner that learns, adapts, and executes with precision, Codebuff deserves a spot in your workflow.
