Updated
Discover Kilo Code, an open-source AI coding agent for VS Code, JetBrains, and CLI. Read about its features, Orchestrator mode, pricing, and alternatives.
Kilo Code is an open-source AI coding agent designed for VS Code, JetBrains IDEs, and CLI environments, supporting over 500 different AI models. Under the Apache-2.0 license, it provides developers with transparent, agentic workflows, inline autocomplete, browser automation, and an orchestrator mode that breaks complex tasks into coordinated subtasks.
Key Capabilities
- Broad Model Support: Access over 500 AI models including Claude, GPT, and Gemini at exact provider rates with zero markup.
- Orchestrator Mode: Coordinates multiple agent modes to break down and complete complex tasks.
- Open-Source License: Fully transparent development under the Apache-2.0 license.
- Multi-Platform Integration: Works seamlessly across VS Code, JetBrains, CLI, and Slack.
- Memory Bank: Stores architectural decisions and project context in structured files to persist understanding across sessions.
- Extensible Architecture: Connects with the Model Context Protocol (MCP) Server Marketplace to expand agent capabilities.
Standout Features
Orchestrator Mode
This feature simplifies complex development objectives by dividing them into structured subtasks. It then coordinates specialized agent modes to execute each subtask sequentially.
Memory Bank
Rather than starting fresh each session, Kilo Code maintains a local store of architectural decisions and project context in structured files, ensuring the AI maintains context of your codebase over time.
Voice Commands
Allows developers to speak requests directly within their IDE, offering a hands-free alternative to typing out long prompt descriptions.
Cloud Agents
For intensive or long-running development tasks, users can run AI agents in the cloud to free up local machine resources.
Automated Code Review
Agents are capable of analyzing pull requests, identifying potential bugs, and suggesting refactoring improvements before code is merged.
Ideal Use Cases
- Multi-Model Flexibility: Best for developers who want to switch between different LLMs depending on the task.
- Open-Source Projects: A natural fit for contributors who prioritize open-source software and transparency.
- Agentic Workflows: Suited for projects requiring autonomous file editing, terminal execution, and multi-step planning.
- Budget-Conscious Development: Cost-effective since users pay direct API provider rates instead of marked-up subscriptions.
Pricing and Plans
Kilo Code operates on a flexible pricing model:
- Free (Bring Your Own API Key): Use the open-source client for free by configuring your own keys for OpenAI, Anthropic, Gemini, or other providers.
- Kilo Pass (From $19/month): A paid credit subscription for developers who prefer a managed experience without setting up individual API keys.
