How it compares
Built for agents from the metal up — every cell sourced.
Snapshots, forks, and pause/resume aren't exotic anymore — several platforms below do them well, and we credit that. The difference is what they're built on. Everyone else is adding agent features to a developer's VM; mrin is a machine shaped to agents — step-by-step replay, suspend that keeps TCP connections alive, and policy decisions that explain themselves. Every non-mrin mark links to the vendor's own docs — spot an error and we'll fix it.
