A free and open-source software to start workloads on demand and stop them after a period of inactivity. Think of it a bit like a serverless platform, but for your own servers. Either because you dont want to overload your raspberry pi or because your QA environment gets used only once a week and wastes resources by keeping your workloads up and running, Sablier is a project that might interest you. Features include support for Docker, Docker Swarm, and Kubernetes, as well as multiple reverse proxies like Apache APISIX, Caddy, Envoy, Istio, Nginx, Traefik, and more. The software can scale up your workload automatically upon the first request, with options for a themable waiting page or a hanging request strategy. It can also scale your workload to zero automatically after a period of inactivity. To explore more about Sablier, check out the documentation [here](https://sablierapp.dev).
