Dora

optr overlap

Closest conceptual comparison to optr — explicit dataflow graph runtime for robotics, Rust-based, modern.

Where we differ: Dora is designed for a single machine with shared memory and a local daemon. optr is designed for anything anywhere — edge, cloud, browser, across NAT, on-chain. If a team wants fast single-machine dataflow, Dora is great. If they need cloud distribution, browser streaming, and agent-native payments, only optr covers that today.
