How to Edit your ComfyUI Security Settings

RunDiffusion users can now edit security settings in the File Manager for ComfyUI to properly install and run more custom nodes.
How to Edit your ComfyUI Security Settings

Installing custom nodes in ComfyUI just got easier on RunDiffusion. Users previously were unable to install some custom nodes in ComfyUI sessions on RunDiffusion. To improve this, we’ve made it possible to edit file security settings unlocking wider node support inside your cloud sessions.

Why You Need to Edit config.ini

By default, ComfyUI Manager enforces strict security policies that block many custom nodes from being installed or used. Altering the security settings allows many more nodes to install and function — but it does not guarantee that every custom node will work.

Some nodes may still have compatibility issues depending on how they are built.

Important Notes

  • Contact us if a node is not working so our support team can troubleshoot the problem.
