Compares two images, writes the output diff and returns the number of mismatched pixels.

Bottery is a prototyping environment and mini-language for designing conversational agents as explicit state machines rather than opaque bundles of code.

A built-in simulator lets you “play” the conversation, test edge cases, and tweak flows without wiring up back-end services first. Because behavior is defined in a DSL, teams can version the...
