Every option in the catalog for when you need to train and simulate a robot with open models — 7 robotics and embodied AI platforms, 7 of them free or freemium, with the pricing tier printed on every row.
Flocci AI Tools lists 7 of them, ordered free tiers first: NVIDIA Cosmos, Genesis, LeRobot (Hugging Face), MuJoCo and NVIDIA Isaac GR00T. Every one of them is free or has a free tier. Each entry states what it uniquely does rather than a score.
7 on this page are marked fully free with no paid plan at all: NVIDIA Cosmos, Genesis, LeRobot (Hugging Face), MuJoCo and NVIDIA Isaac GR00T. The remaining 0 are freemium, trial or paid, and each is labelled with its exact tier so nothing surprises you at sign-up.
Free tools first, then freemium, then trial, then paid, and alphabetically inside each tier. Nobody pays to appear higher: Flocci AI Tools carries no ads, no sponsored slots and no paid listings, so the order reflects price and nothing else.
NVIDIA Cosmos works in a browser tab with no install needed — just open the site and go. 1 of the 7 free robotics and embodied AI platforms listed here are browser-based.
Genesis, LeRobot (Hugging Face), MuJoCo, NVIDIA Isaac GR00T and NVIDIA Isaac Lab can be self-hosted or run locally without a browser — useful for privacy, air-gapped networks, or avoiding API rate limits. 6 of the 7 free robotics and embodied AI platforms here run offline.
