QEMU vGPU passthrough beats Firecracker for WebGL browser automation.

Strengths
  • Wire-protocol GPU acceleration means existing agents work without code changes.
  • 60 FPS on WebGL aquarium benchmark where competitors render single static frames.
  • Migrated from Firecracker to QEMU specifically to enable device passthrough.
Weaknesses
  • Limited research preview only, requires startup or enterprise plan for access.
  • Niche audience—only matters if you're already running cloud browser agents.
