Hardsim is a cloud simulation platform for robotics teams that want to run large simulation workloads without managing Kubernetes, GPU provisioning, or container orchestration. Built and operated by Hardlight.

What You Can Do

Submit simulation jobs from Python with pip install hardsim.
Run parallel simulation workloads against cloud GPU workers.
Download artifacts (render.mp4, rollout logs, manifests) from completed jobs.
Download diagnostics artifacts (runner.log, diagnostics.json, user_job.log) from failed jobs.
Track usage and billing in credits.

Quick SDK Flow

import hardsim as hs

robot_asset_id = hs.upload_input_asset("./assets/robot.urdf", asset_kind="robot")
scene_asset_id = hs.upload_input_asset("./assets/scene.usd", asset_kind="scene")
job = hs.submit_assets(robot_asset_id=robot_asset_id, scene_asset_id=scene_asset_id, robot_asset_type="urdf", num_envs=64, steps=2000)
result = hs.wait(job.job_id)
paths = hs.download(job.job_id, "./outputs")
