Editors' review
An open-source VS Code agent — bring your own key, keep control
Cline is an open-source AI coding agent that runs as a VS Code extension. Because it works on your own API key — Anthropic, OpenAI, Bedrock or a self-hosted model — you control both the cost and where the data goes.
The extension itself is free with no monthly charge. That matters in environments where internal policy says cloud SaaS cannot be used, or where only models in a specific region are permitted.
Being open source, you handle key issuance and billing yourself, and support is community-based rather than contractual.
Verdict
The option for BYOK-minded individual developers and for organisations that cannot put a SaaS coding tool through review.
