Both put one monday.com item on several boards. The difference that lands on your bill: Mirror Item counts a shared item once, no matter how many boards it lives on. Same Item Multiple Boards counts it once per board, so the same plan stretches up to 3× further with Mirror Item.
Full disclosure: we build Mirror Item. We've kept this comparison factual, so you can judge for yourself.

Mirror Item Multiple Boards and Same Item Multiple Boards both let one item live on several monday.com boards, kept in sync, so each team works from its own board without copy-pasting. If you're weighing an alternative to Same Item Multiple Boards, this comparison lays out exactly how the two differ.
A quick example makes it clear. Take one item and add it to 3 boards: Mirror Item counts that as 1 item against your plan, while Same Item Multiple Boards counts it as 3. So on the same plan you get about 3× more usable items with Mirror Item, and the gap grows the more boards an item lives on.

Both apps offer a free plan, so you can trial either one, or run them side by side, before paying. Mirror Item's paid plans start at $37/month; check each listing for current pricing.

What teams say about Mirror Item
“It works exactly as it should. But the real signifier with this application is the customer support. Arnav is incredible. He added capabilities without me even asking, he saw a need and delivered without request!”
“The app is structured very logically, works well, and is something monday needed. I would not have been able to build out a planning board without this feature.”
“The support team and function of the app has been nothing short of 1st class. They answered every question I had within a 30 minute timeline, and made an adjustment to accommodate our needs.”
