Yes, the Cline open source extension is completely free for individual developers. You only pay for AI inference on a usage basis, with no subscriptions or vendor lock-in. You can bring your own API keys or use the Cline provider.

You only pay for AI inference credits when you use AI models, which is usage-based pricing. Open Source Teams is free through Q1 2026 and includes up to 10 seats free even after that.

Can I use my own API keys?

Absolutely! You can bring your own API keys from providers like OpenAI, Anthropic, Google, and others, giving you complete control over your costs and usage.

What's included in Open Source Teams?

Open Source Teams includes all Open Source features plus JetBrains extension, centralized billing, simple config management, role-based access control, inference provider limits, team management system & dashboard, and priority support. It's free through Q1 2026, then $20/month per user, with the first 10 seats always free.

When do I need Enterprise?

Enterprise is for organizations requiring advanced features such as SSO, OIDC, SCIM provisioning, audit logs, VPC deployments, SLA, OpenTelemetry, and dedicated support.

Is there vendor lock-in?

No, Cline is open source and supports a wide range of providers like Anthropic, Gemini, OpenAI, AWS Bedrock, GCP Vertex, Groq, Cerebras, and DeepSeek, allowing you to switch providers or self-host anytime.

About Cline

Cline is an open-source AI coding agent that integrates directly into your IDE (VS Code, JetBrains) and terminal. It empowers developers to read, write, and refactor code, execute commands, and use a browser through natural conversation, always requiring explicit approval for actions. It emphasizes security with client-side processing and flexible deployment options, supporting a wide range of frontier AI models.

What Makes Cline Unique

Cline stands out with its client-side architecture, ensuring user code and prompts never leave their infrastructure. It offers unparalleled data security and sovereignty by allowing users to bring their own AI inference providers or deploy the agent on-premise, in VPCs, or air-gapped environments.

Data ResidencyCline's architecture is client-side, meaning code and prompts do not go to Cline's servers. Users can connect directly to various AI providers (Amazon Bedrock, GCP Vertex, Azure OpenAI, or models on their own servers) to keep data within their security perimeter and deploy on their infrastructure (VPC, on-prem, or air-gapped environments).
