Kilo.ai

Kilo.ai (Kilo Code) is an open-source (Apache 2.0) AI coding agent for VS Code, JetBrains, CLI, and cloud surfaces, with specialized modes (Code, Architect, Debug, Ask, Custom), multi-model support (500+ via Kilo Gateway or BYOK), MCP, and cloud agents. We rate it assess under AI Agent: a credible open-source alternative in the same lane as OpenCode and IDE-bound agents, but not yet our default stack (Cursor + cursor-agent for daily work).

Blurb

The Open Source AI Coding Agent for VS Code, JetBrains, and your CLI. Build, ship, and iterate with any model, everywhere you work.

Summary

Kilo Code (kilocode.kilo-code on VS Code / Open VSX) runs an agent loop in the editor or terminal: codebase-aware context, inline autocomplete, terminal and browser automation, code review, and human-in-the-loop controls. Kilo Auto offers a free tier without a credit card; paid tiers and BYOK cover model usage. A separate product, KiloClaw, is managed hosting for OpenClaw-style omnichannel agents (Telegram, Discord, Slack) — outside the repo-bounded AI Agent sweet spot we prefer for coding workflows.

Worth evaluating when you want Apache-licensed, multi-surface agents with model portability and less vendor lock-in than a single IDE subscription. Compare OpenCode for terminal-first multi-provider hubs; Cursor when the editor platform is the anchor.
