I use the visualizer and just worked through the examples and tutorials on the Alloy website. It takes a little bit to get used to, but the visualizations really help to see what&#x27;s going on.<p>What I like Alloy for is checking to see if the operations you&#x27;re defining to maintain a data structure actually maintain the desired invariants. It&#x27;s nice for situations where you&#x27;re not actually sure that what you&#x27;re &quot;trying to do&quot; will even work like you expect.<p>With Coq, I tend to already know something will work and just want to verify that I&#x27;ve achieved it, so it&#x27;s much less exploratory in nature.
