Add LoRA support in cloud relay mode by mjh1 · Pull Request #442 · daydreamlive/scope

mjh1 · 2026-02-11T14:14:19Z

Enable LoRA browsing, selection, and install-by-URL in both cloud and local modes. Previously the LoRA UI was completely hidden in cloud mode and the backend had no cloud proxy for the LoRA list endpoint.

Backend: add cloud proxy to GET /api/v1/lora, add POST /api/v1/lora endpoint with filename inference, extension validation, and duplicate detection. Add 5-min timeout for LoRA installs in fal_app.py.

Frontend: remove isCloudMode gates in SettingsPanel and ComplexFields, switch LoRAManager to useApi hook for cloud-aware routing, add installLoRAFile to api/cloudAdapter/useApi, add install URL input UI.

Enable LoRA browsing, selection, and download-by-URL in both relay and direct cloud modes. Previously the LoRA UI was completely hidden in cloud mode and the backend had no cloud proxy for the LoRA list endpoint. Backend: add cloud proxy to GET /api/v1/lora/list, add POST /api/v1/lora/download endpoint with filename inference, extension validation, and duplicate detection. Add 5-min timeout for LoRA downloads in fal_app.py. Frontend: remove isCloudMode gates in SettingsPanel and ComplexFields, switch LoRAManager to useApi hook for cloud-aware routing, add downloadLoRAFile to api/cloudAdapter/useApi, add download URL input UI.

LoRAManager: use useCloudStatus hook to disable download input/button while cloud is connecting, show inline "Waiting for cloud connection..." message. Use sonner toast.promise() for download progress feedback. Backend: add response status checks in cloud proxy paths for /lora/list and /lora/download to properly surface errors instead of crashing on empty response data.

@yondonfu @leszko question about the UI for this, currently it's just a little input box in the settings panel:

Should we make it like the plugins install UI instead, so another tab in the settings dialog?

IMO yes, installing LoRAs should be from the Settings. But happy to hear @yondonfu and @ryanontheinside thoughts.

Looks good. Just 2 questions:

Don't you want to move this Download into the Settings?
How do you clean up it for the Cloud usage? I mean so that one user would not see loras from another user? Or you just use the ephemeral container storage?

frontend/src/components/LoRAManager.tsx

+    try {
+      const installPromise = installLoRAFile({ url });
+      toast.promise(installPromise, {
+        loading: `Installing ${filename}...`,
+        success: response => response.message,
+        error: err => err.message || "Install failed",
+      });
+      await installPromise;
+      setInstallUrl("");
+      await loadAvailableLoRAs();
+    } catch (error) {
+      setInstallError(
+        error instanceof Error ? error.message : "Install failed"
+      );
+    } finally {
+      setIsInstalling(false);
+    }


Nit: I think you'll display the toast with error twice here.

loadAvailableLoRAs should be here in the dependency array.

this has moved but it's fixed now 👍

This doesn't seem to support CivitAI right now. Using the download URL for https://civitai.com/models/2383884?modelVersionId=2680702 results in an error about an invalid file extension.

Since the current LoRA user guide calls out that LoRAs can be sourced from HuggingFace and CivitAI and given that the latter is popular for LoRAs, I think we should make sure that is supported before introducing the LoRA download feature.

The linked LoRA guide contains guidance on how to programatically get the LoRA from CivitAI which might be a useful reference here. It will require a CivitAI API key which can be configured in the API Keys tab and the existing API key handling code might be specific to HuggingFace so it would just need to be tweaked a bit to handle CivitAI API keys too

I like this idea!

@yondonfu @leszko maybe we can avoid the complication of maintaining civitai API keys and just prompt the user to add a token queryparam? I've implemented it like that for now, see what you think 🙏 (the file extension issue is fixed now)

@leszko The settings tab is implemented now 👍

And yes it just uses ephemeral storage which is cleaned up after every connection
