I've written a small open-source tool that serves preview thumbnails of all your vMix inputs over HTTP — a modern replacement for the old vmix-snapshot-proxy some of you may remember.

What it does: it connects to the vMix Web API, reads all inputs, captures previews via the SnapshotInput API and serves them on port 8098. Inputs are identified by their key/UUID instead of the input number, so nothing breaks when you reorder your session. Thumbnails are optimized to ~10 KB (with ffmpeg, optional), there's a visual web UI with a live grid, and the legacy /{number}.jpg URLs still work so existing integrations keep running. Single .exe, zero configuration, no Node.js required.

Useful for custom dashboards, Companion button images, tally or monitor pages — anything that wants to show what's actually on an input.

Full disclosure: I originally built it as a free companion for my own vMix tooling, but it's completely standalone and stays that way. MIT license, full source public on GitHub: https://github.com/adelv...ware/dp-thumbnail-server — it has also been picked up by the community-maintained awesome-vmix list.

If anyone is interested or has ideas for it, let me know.
