Replacer tab doesn't appear (lllyasviel/stable-diffusion-webui-forge)

[passthesh3ll]

Hello,
I use https://github.com/lllyasviel/stable-diffusion-webui-forge and the tab Replacer (installed from extensions) doesn't appear.

I think I'm not using the correct webui, can you tell me what's the most updated compatible ui or if I can keep the current one?

[light-and-ray]

This extension is not compatible with Gradio 4 Forge. Use reforge or forge classic instead. Also it looks like you don't have segment anything extension

[passthesh3ll]

Could you confirm they are these:

• https://github.com/Panchovix/stable-diffusion-webui-reForge
• https://github.com/Haoming02/sd-webui-forge-classic

What's the best in your opinion for stability and future support between reforge and forge classic ?
Thanks for your time

[light-and-ray]

I didn't use any of forks of forge or a1111. Currently I have switched to comfy ui, with my extension there called MCWW
