emdash is an electron desktop app that wraps cli coding agents in a gui, 23 adapters, typescript. bernstein is a python cli plus library plus mcp server, 37 adapters, with a textual tui rather than a native window. emdash is the right pick if you want a downloadable desktop ade with one-click setup. bernstein is the right pick if you want headless ci / mcp / library use, a deterministic scheduler, an hmac audit chain, and pluggable cloud sandboxes. they are not direct substitutes; some teams run emdash for interactive work and bernstein for unattended batch runs.
