Sync
Zoom once, not twice
Pan and zoom drive both panes together, so you are always looking at the same crop instead of hunting for it twice.

This is the app.
Every image indexed with its full generation context, filterable by checkpoint, LoRA, sampler, scheduler and ComfyUI node, grouped into the sessions that produced them. That part is free. Pro is everything below it.
Library — 15,930 images, faceted filters, session grouping
Compare View — side-by-side with metadata diff
Find out which change actually did it.
Put 2 to 4 outputs side by side and Image MetaHub diffs their metadata for you — highlighting the exact prompt words, seeds, steps, CFG and samplers that differ. No more guessing which of six tweaks moved the result.
Word-level prompt diff
Seven ways to look at the same two images.
Side-by-side, slider, hover, flicker, diff map, loupe and edge detection — with synced pan and zoom, a quantified visual delta, and a jump to the strongest-changed region.
Delta
Put a number on it
Changed percentage, average delta and canvas size, so "basically the same" becomes a measurement.
Edge comparison with visual delta
Synced zoom — both panes stay locked to the same region
The ComfyUI workflow, rebuilt from the image.
Open any ComfyUI output and Image MetaHub reconstructs the graph that made it — every node, every connection, with an inspector for the values that matter. Then send it back to ComfyUI or Automatic1111 and generate again.
Workflow Tools — reconstructed node graph with inspector
Analytics Explorer
Know what you actually use.
Which checkpoint really produces your keepers, which LoRAs you loaded twice and forgot, how your output volume moves over time. Scope it to a filtered set or the whole library, then compare cohorts directly.
Pro also includes a built-in image editor — adjustments, crop, rotate, resize, sharpen, annotations, text and blur regions — that writes back with your generation metadata intact, so an edited file never loses its prompt.
Free vs Pro

What people say after trying the alternatives
"I was absolutely floored by the level of quality in this application. I had almost lost hope after going through the small number of other options in this space (both standalone applications and ComfyUI extensions) and then I discovered Image MetaHub and there is absolutely no comparison — this is head and shoulders above every other option in this space. The thoughtfulness that has clearly gone into both functionality and UI/UX is very much appreciated, and the parsing speed is amazing after what I experienced in a few of the other apps I tried recently."
— via GitHub"I can't recommend this highly enough. I've been using it for the last month or so and it's extremely helpful and well thought out. The developer releases updates frequently and is very responsive to feedback. The free version is very capable but I recently sprung for the full version."
— u/According_Boat_6928, r/comfyui"Just tried it and here are my impressions (testing with 10k images): Sleek UI, intuitive, facet filters and full text search, copy prompt shortcuts. App is snappy, reloading a folder is fast, filtering is almost instant. Performance is good, RAM stabilizes around 350MB."
— u/jambavant, r/StableDiffusionOne payment. No subscription. Ever.
Nearly everything else in this space bills you every month, forever. Pro is $39 once — and it stays yours, including every future Pro update.

Questions
Does it work offline?
Yes. Image MetaHub is local-first — indexing, search, browsing and Pro tools all run on your machine. Pro's generation features talk directly to a ComfyUI or Automatic1111 server you're already running locally, not a cloud service.
Is my data private?
Your images, video, audio, cache, tags and metadata stay on your machine. Nothing is uploaded unless you deliberately open an external link or integration.
Which platforms are supported?
Windows, macOS (Intel and Apple Silicon) and Linux.
How does the license key work?
After checkout you'll get a license key by email, issued manually within 24 hours. Enter it in Image MetaHub to unlock Pro on your existing free install — it's a one-time purchase, not a subscription, so there's no recurring account check.
How many machines does one license cover?
A single Pro license activates on one machine at a time. If you need to move it to a new computer, contact support and we'll help you transfer it.
Are future updates included?
Yes. Pro is a one-time, lifetime purchase — all future Pro updates and feature additions are included at no extra cost.
