Cline

Cline is an open-source AI coding agent that runs inside the editor or the terminal. It reads a codebase, plans changes in a Plan mode, and then carries them out in an Act mode. It can edit multiple files, run terminal commands and use a browser, and it asks the developer to approve each step. The free open-source tier includes a VS Code extension, a CLI with headless use for CI/CD pipelines, multi-root workspaces and an MCP Marketplace for connecting external tools. Cline does not mark up model usage. You bring your own API keys for any of the major providers or local models, or you buy inference at cost through the Cline provider. That makes it suitable for individual developers and engineering teams who want to choose their own model. The Enterprise plan is priced through sales. It adds a JetBrains extension, SSO with OIDC and SCIM, role-based access control, centralized billing, limits on which inference providers can be used, audit logs, OpenTelemetry export and VPC deployment. Cline's press release says Samsung and SAP are among its enterprise users. The main limitation is cost predictability: because you pay per token, heavy agentic sessions can produce large API bills. Users report bills of tens to hundreds of dollars a month, and the per-step approvals can slow large refactors.
