Cline
Cline is an open-source autonomous coding agent aimed at developers who want plan-and-act workflows inside VS Code, JetBrains IDEs or a terminal session. It proposes file edits and shell commands, then waits for explicit approval so you stay in control of what touches the repo. People often pair it with their own API keys from major model providers, or buy inference billed closer to cost instead of a classic seat subscription. That design keeps the extension free for individuals while still letting power users spend on stronger models when a task needs them. Enterprise packaging exists for teams that need SSO, SLAs and centralized billing rather than personal keys. Limitation: without BYOK or a paid inference path the agent cannot call frontier models on its own, and heavy refactors still need human review before merge. Treat every approved command like any other junior-engineer change—tests remain mandatory.
Key features
- Open-source coding agent for VS Code, JetBrains and terminal
- Plan/act loops with human approval before edits or commands
- BYOK or at-cost inference; Enterprise for SSO-centric teams
Limitations
The extension is free, but model usage is not—bring your own keys or pay for inference; Enterprise features are custom/contact-sales.
