I'll start with a caveat: I don't play miniature based games.
But I ran into something I thought might help with miniature movement style games.
A free site called Dungeon Map Doodler is a pretty solid map-making tool. Maps can have multiple, fully toggle-able layers, and customized "stamps" can be uploaded to act as the miniatures.
Like other online tools, you can save as an image for upload to imgBB or whatevs.
Unlike other (free, useful) online map tools I've found, this site allows free offline work thru a chrome extension.
The kicker is you can save the map file (separate from the final image) for later editing: so each set of miniature movements is as simple as loading the saved map on their site, moving each "stamp" with a click and drag. Resave map, re-DL image file, and voila!
It's VERY simple to move the miniatures without hassle or screwing other map elements up.
The UI is simple and intuitive.
May not be a perfect solution, but not needing to login or join while still using a powerful online map generation tool may appeal greatly to some.
Hope someone finds this useful! :)
Edit: It's key to note that this process allows for each "game state" to be saved as a map file vs. as a snapshot image, which seems more elegant and useful (not to mention less work).
I'm not 100% sure linking to off-site stuff is allowed, so apologies to mods if this isn't kosher:
