Show HN: Cerulion – ROS 2-compatible robotics runtime with multi-process replay
Hey HN! I'm Lakshay. Raveen and I have built Cerulion, a ROS2-compatible robotics runtime written in Rust. We've worked hard on lowering IPC transport latencies without making the single process tradeoff or forcing POD message types. These fast multi-process graphs can then be resimmed deterministically, and existing ROS2 nodes/launch files can run unmodified alongside native Cerulion Rust/Python code. Installation and quickstart (with a one-shot prompt for your favorite coding agent) here at th

Observed adoption & comparisons
Source votes: 8 votes (Nov 13, 2026 UTC; cumulative since publication) Recent records to compare: “addyosmani/agent-skills” (GitHub Trending, Nov 13, 2026); “CopilotKit/OpenBot” (GitHub Trending, Nov 13, 2026). Shared themes are navigation hints; they have not been verified as the same need or independent corroboration.
Adoption decision
Evaluate it against the tool or manual workflow it would replace. The stored record supports discovery; it does not yet establish reliability, lower operating cost or commercial adoption.
Unverified requirements
Not verified: license permissions, required hardware, installation steps, maintenance status and a representative task with its failure cases.
Next test
Choose one real task and a current alternative. Record the commit, environment, input, output, elapsed time and failure behavior; retain the result before recommending adoption.
