Kilo Code

Kilo Code is the most popular open-source AI coding agent, available for VS Code, JetBrains IDEs, and the command line. It helps developers write, refactor, and ship production-ready code by acting as a deep-context agent that understands the entire codebase. Version 7 brings a complete architectural rebuild on OpenCode server — a portable open-source core that now powers the VS Code extension, the CLI, and Cloud Agents from a single engine. The headline additions are parallel tool calls and subagent delegation: Kilo can run file reads, terminal commands, and searches simultaneously, and spin up multiple specialized subagents that work concurrently before merging results. Other new features include the Agent Manager for running and monitoring multiple agents side by side, inline code review with line-level comments, and multi-model comparisons that let you run the same prompt across 500+ supported models at once. Sessions now carry over seamlessly between the CLI and VS Code. Kilo Code is free to start with no credit card required and is released under the Apache-2.0 license, making it fully auditable and self-hostable.
