Best Alternatives to Kilo Code for JetBrains in 2025
Kilo Code for JetBrains is a powerful, fully native open-source coding agent that brings parallel agent execution, isolated worktrees, and multi-model flexibility directly into JetBrains IDEs. While it excels for developers who want deep IDE integration and open-source control, you might be exploring other options for different workflows, team preferences, or model ecosystems. Below are the best alternatives to Kilo Code for JetBrains, each with distinct strengths.
GitHub Copilot
The most widely adopted AI pair programmer, offering seamless multi-file suggestions, chat, and agent mode across JetBrains and VS Code. It's ideal for teams already invested in GitHub, with strong enterprise security, code review integration, and a proven track record—though it's not open-source and lacks Kilo's parallel worktree isolation.
Cursor
The AI Code Editor
A standalone AI-first code editor (fork of VS Code) that provides an exceptional agentic coding experience with deep codebase understanding, multi-file edits, and a polished UI. It's a top choice if you prefer a dedicated editor over a plugin, but it doesn't run inside JetBrains and requires migrating your environment.
JetBrains AI Assistant
The native AI solution from JetBrains, tightly integrated with all JetBrains IDEs. It offers context-aware code completion, refactoring, and chat, plus seamless integration with JetBrains' own tools like Space and YouTrack. It's the most frictionless option for JetBrains-only users, but it's proprietary and less customizable than Kilo's open-source approach.
Windsurf
An AI-native IDE from Codeium that emphasizes agentic workflows and 'flow state' development, with powerful multi-agent capabilities and a free tier. It's a strong alternative for developers who want a modern, AI-first editor with excellent performance, though it doesn't support JetBrains plugins and has a different model catalog.

Your AI pair programmer in VS Code
An open-source AI code assistant that works as a plugin for both JetBrains and VS Code, offering full control over models, prompts, and local/remote execution. It's the closest open-source alternative to Kilo, but it lacks Kilo's parallel agent isolation and native worktree management, focusing more on customizable autocomplete and chat.
Aider
A command-line AI pair programming tool that excels at git-native workflows, automatically committing changes and supporting multiple models. It's perfect for developers who prefer terminal-based agents and want transparent version control, but it doesn't provide a GUI or JetBrains integration, making it less suitable for IDE-centric teams.
Tabnine
An AI assistant that prioritizes privacy and security, offering on-premise or private cloud deployment with code completion and chat. It's a solid choice for enterprises with strict data governance, but it's less agentic than Kilo and doesn't support parallel agents or worktree isolation, focusing more on inline suggestions.
Kilo Code for JetBrains stands out for its open-source nature, native JetBrains integration, and advanced parallel agent workflows. If you need a similar open-source plugin with model flexibility, Continue is the closest match. For teams prioritizing GitHub ecosystem or enterprise security, GitHub Copilot is a robust choice. If you're open to switching editors, Cursor and Windsurf offer cutting-edge agentic experiences, while JetBrains AI Assistant provides the smoothest native experience for JetBrains loyalists. Evaluate your priorities—IDE lock-in, open-source control, agent complexity, or team collaboration—to pick the right fit.
