About Kilocode
Kilo is an open-source AI coding agent that operates across IDEs (VS Code, JetBrains), CLI, and cloud environments, enabling developers to build, ship, and iterate faster. It offers multiple agent modes (Code, Architect, Debug, Custom) and supports 500+ AI models with zero markup through its Gateway. Key capabilities include code generation, autocomplete, voice prompting, automated code reviews, cloud agents for long-running tasks, one-click deployment, and session handoff across platforms. Kilo is MIT-licensed, fully inspectable, and can be self-hosted. Pricing is transparent: the open-source agent is free; AI inference is billed separately via pay-as-you-go or subscription (Kilo Pass), with a free tier available for local models or BYOK.
Key Features

FAQ
Is Kilo Code really free?
Yes, the Kilo Code open-source agent is free to use. AI inference costs are separate; you can use free models via Auto Free, bring your own keys, or pay as you go.
What is AI inference and why is it priced separately?
AI inference is the cost of running AI models (e.g., GPT-4, Claude). Kilo charges no markup on inference—you only pay the provider rates when using Kilo Gateway or Kilo Pass subscriptions.
What's the difference between Kilo Gateway and Kilo Pass?
Kilo Gateway is pay-as-you-go hosted AI inference with no subscription (pay exact provider rates). Kilo Pass is a monthly credit subscription that gives up to 50% bonus credits on top of your payment.
How does Auto Model affect AI inference cost?
Auto Model routes your tasks to the most appropriate model based on your selected tier (Free, Balanced, Frontier, Efficient). It automatically balances cost and capability, helping you save on inference spend.
What do Teams and Enterprise plans add?
Teams ($15/user/month) adds usage analytics, centralized billing, team management, shared BYOK, and data privacy controls. Enterprise adds SSO, audit logs, SLA, custom security, and dedicated support.
Do I need a subscription to start?
No. You can start with the Free open-source plan and choose to pay for AI inference later via pay-as-you-go or bring your own keys.
