Reverb is typically a digital effect, and this is because the sound of an analog reverb is created with a physical space. Original plate reverbs required large sheets of metal that were vibrated. Analog spring reverbs use metal springs to create their unique tone. Echo chambers required that sounds be played into a physical space, captured with a microphone, then input back alongside the dry signal to create the sense of space.
This is why you won’t find many analog reverb pedals. Unless you wanted to cart around a bunch of metal plates with you there would be no physical way to actually do it! There are some pedals that have a physical spring inside them, like those from Danelectro and Gamechanger Audio, but these are few and far between. For the most part, if you want an analog reverb sound, you’ll either need to rely on an amplifier with a spring reverb built in, or stick to digital.
