Roo Code

Roo Code for AI Engineer is a custom version of Roo Code for enterprise use cases with no telemetry. As a fork of Cline, it keeps the same core agent workflow while adding more control and configuration options for power users.

  • High-performance Cline fork optimized for speed and cost control
  • Mode-based guardrails to limit actions by role and risk
  • Efficient line-based diffs to reduce large file rewrites
  • Best when you want agent power with tighter operational control

  3. In VS Code, open Extensions, open the three-dot menu, and choose Install from VSIX.
