Is Cline safe? How to secure your Cline app
Cline is an autonomous coding agent in your editor — review its generated code and be deliberate about its permissions.
Cline is safe to use, but as an autonomous agent that edits files and runs commands, the risk is twofold: the code it generates can be insecure, and its broad access can expose secrets or run unvetted commands. Review its diffs and approve actions before they run.
Cline is an autonomous coding agent that runs inside your editor, and it is safe to use. Because it edits files and executes commands on your behalf, the security considerations are the same as any agent: the code it writes can be insecure, and its broad access means committed secrets and unvetted commands are the things to watch. Review its proposed diffs, approve commands deliberately, and keep credentials out of tracked files.

The most common Cline security risks
Insecure generated code
Cline can produce code with exposed secrets, missing authorization or injection flaws. Review security-sensitive output.
Command execution
The agent can run shell commands. Approve them deliberately and avoid auto-approving destructive or network actions.
Secrets in the workspace
An agent reading your whole workspace can surface or commit secrets if .env files aren't ignored.
