Kilo Code
Kilo Code is an open-source VS Code extension forked from Cline, focused on reliability and team-friendly features for autonomous coding workflows. Kilo is free and bring-your-own-key against any major LLM provider. The fork's emphasis is on production-grade behaviors - predictable diff application, recoverable failures, and team-shareable configurations.
Overview
VS Code extension forked from Cline, offering autonomous coding agent capabilities with a focus on reliability and team-friendly features.
Compare Kilo Code side-by-side with other CLI, IDE, cloud, and framework agents on pricing, model coverage, and release cadence.
Best LLMs for this agent
Claude Sonnet 4.6 is one of the most-used Kilo Code pairings for autonomous coding because it balances edit accuracy and cost.
Claude Opus 4.6 is the stronger Claude pairing when Kilo Code needs deeper reasoning over a larger change.
DeepSeek V4 Pro is the standard open-weights alternative for teams using Kilo Code with cost-sensitive provider routes.
Pricing and Provider Comparison
Hosted agents expose plan pricing. Bring-your-own-key agents pass the main cost through the model provider route you configure.
