3.2 Cooling Magnitude out of 10. Star growth looks organic. Data as of September 14, 2026.

About the project

A Python library for running thousands of MuJoCo simulations in parallel on CPU via a C++ thread pool, with live access to per-simulation state and parameters.

Useful for

Train a PPO controller for Go1 on 4096 parallel environments without a GPU
Run iLQR or predictive sampling MPC for swing-up tasks
Perform SysID and hardware co-design by sweeping model parameters

Why it’s trending

40 stars today.
Interest is fading: the two-day pace is 17% of the previous week and a half.
The spike has held for 3 days in a row — not a one-off blip.
The repository is 3 days old and already has 406 stars.
Top new repositories this week: #27.
About 6 forks a day — people are taking the code.

Star trust

Growth looks organic: forks and discussion are in line with active projects, and stars arrive unevenly, the way people give them.

These are heuristics, not a verdict: we judge by the repository’s behavior, not by a list of stargazers.
