RenderStreet is a cloud render farm for Blender, running since 2012. Blender Internal was Blender's original built-in renderer, used through Blender 2.79 alongside the Freestyle NPR system. RenderStreet supports Blender Internal for projects built in those older Blender versions, so you can keep rendering legacy scenes without maintaining your own hardware.
Legacy Blender Internal and Freestyle projects render on demand from $3.00/server-hour, billed by the minute. For newer work, Blender's current Cycles and EEVEE engines are fully supported, with CPU and GPU rendering and unlimited CPU rendering from $59.97/month on RenderStreet One.
