Version Check Pixaroma

Version Check Pixaroma is a diagnostic label that tells you the four things that actually matter when a ComfyUI workflow misbehaves: the ComfyUI backend version, the frontend version, which node interface is active (the new "Nodes 2.0" or the classic one), and the installed Pixaroma version. It's a panel on the canvas - no inputs to wire, no outputs to chain, no Python work on run. Drop it, read it, done.

It sounds boring until the first time you need it. Pixaroma updates roughly every few days, ComfyUI updates constantly, and the pack has a documented failure mode: after an update, your browser can keep serving the old cached node code even though the new files are installed. That mismatch produces blank or glitchy nodes for no obvious reason, and the classic fix - hard-refresh with Ctrl+Shift+R - only makes sense once you know a stale cache is even possible. This node exists to make that state visible.

What you get

The panel shows the four version lines with a Copy button that puts them all on your clipboard as plain text - ready to paste into a bug report or a Discord #pixaroma-nodes message. That matters more than it sounds: "works for me" reports are useless, and this makes it a two-click operation to give the author the exact environment. There's also a Refresh button that reloads the page, and clicking the interface row switches between Nodes 2.0 and Classic without digging through Settings.

Since v1.4.3 the node got smarter: if your browser is running older code than what's installed, the Pixaroma line turns orange with an explicit "press Ctrl+Shift+R" warning, and the Copy output includes it. It's a version check that has opinions about your cache, which is exactly the right opinion to have.

When you'd reach for it

Three honest use cases:

• Something broke after an update. Drop the node, read the orange line, hard-refresh. That fixes more "bugs" than any other single action in this pack.
• You're about to ask for help. Copy the four lines and paste them with your question. You'll get a useful answer instead of a back-and-forth about versions.
• You're not sure which interface you're in or how new your ComfyUI is. Some nodes (like the Set/Get pair) need a minimum frontend version; this panel answers that on sight.

Installing it

Same as every Pixaroma node - it ships in the ComfyUI-Pixaroma pack. ComfyUI Manager: search Pixaroma, Install, restart. Or manually:

cd ComfyUI/custom_nodes
git clone https://github.com/pixaroma/ComfyUI-Pixaroma

No dependencies, no models. It's intentionally the least demanding node in the suite.

Gotchas

Nearly none, since it's read-only. One quirk: it's deliberately not an output node, so ComfyUI skips it on run and it never draws a "X.Xs" timing badge over the panel - that's by design so the diagnostic doesn't look like a workflow node. And yes, the browser-cache warning itself only appears if your browser is actually running stale code; if the line stays calm, the cache is fine and your problem is elsewhere.
