sheepit renderfarm is a free and open source community powered renderfarm. You contribute your computers processing power to render frames/projects for others and get points for it. Those points you can spend for rendering your own projects. The points are only used to determine the queue position, meaning more points, higher priority. I've been a user since 2018, no bigger complaints so far. The only issues arise sometimes from overloaded servers, however that's a funding issue. The devs and admins work very hard to keep the service running quite well. For support join their discord, admins and the community will help you very quickly.
