Hi, I’m building an agent in conversation flow, rigid mode and the canvas is getting very sluggish. I have to wait a while after every single click or drag.
There are probably 40-50 nodes on the canvas now. I’m wondering if that’s normal behavior for 40-50 nodes or if there’s anything that can be done to improve that experience.
Thank you for reaching out to Retell AI Support. We’ve received your ticket and our team will respond within 8 hours.

Hi Retell,
It sounds like you’re seeing sluggish canvas interactions in Conversation Flow (rigid mode) with ~40–50 nodes. Regarding whether this is “normal,” there isn’t a hard node limit, and large flows are supported, but complex graphs can feel heavy to manage visually.
To improve the editing experience:
- Use the canvas Organize action to auto-layout the graph and reduce redraw strain.
- Break the flow into Components (mini-flows you can reuse). This keeps the main canvas lighter and easier to navigate, while preserving functionality. See Components and the Node overview.
If you can share a quick screen recording or screenshot plus your agent’s agent_id, I can take a closer look at whether there’s a specific performance issue with your canvas. Also let me know your browser and OS.
Did this help, or would you like me to review the specific flow once you share the details?
Best,
