Cline overview and key facts (October 2026)
Open source coding agent as a VS Code extension, CLI and SDK, where you pay only for model usage.
What is Cline?
Cline is an open source autonomous coding agent available as a VS Code extension, a CLI and an SDK. Developers connect the model provider of their choice and pay only for inference, while companies can buy an Enterprise edition with single sign-on and support.
The open source version includes the VS Code extension, the CLI, a client-side architecture, an MCP marketplace and multi-root workspaces. The README also lists a JetBrains plugin on the JetBrains Marketplace, a desktop app for macOS and Windows and an SDK. Inference is billed by usage through the Cline provider or through your own keys for OpenAI, Anthropic, Google, AWS Bedrock, GCP Vertex and others.
The Enterprise plan adds SSO, SLAs, dedicated support, centralized billing, role-based access, inference provider restrictions and authentication logs, and the pricing page lists the JetBrains extension there as well. The repository is under Apache 2.0, had 69,477 stars and was updated on September 28, 2026.
Cline AI features and use cases
- Completes tasks inside VS CodeCline reads the project, proposes file edits and terminal commands and carries them out after approval. Developers delegate multi-step changes without leaving their editor.
- Uses the company's approved modelBecause Cline works with many providers and own keys, teams can route it through a model and cloud already cleared by IT, such as AWS Bedrock or GCP Vertex. Data stays within existing contracts.
- Extends the agent with toolsThe MCP marketplace adds tools such as database access or ticket systems. Teams can let the agent read context from their own systems while coding.
What sets Cline apart
- No subscription for individuals: you pay only for model inference.
- Client-side architecture, so code goes directly to the provider you configure.
- Enterprise edition restricts which inference providers staff may use.
Where Cline is strongest

Questions to ask before you buy Cline
