Piku is a platform that allows users to deploy applications to their own servers using a git push workflow, similar to Heroku or CloudFoundry, but without the need for Docker. It supports multiple programming languages and can run on low-end devices, making it accessible to hobbyists and small-scale deployments. Piku is designed to be simple and easy to use, with a focus on stability and backwards compatibility. It can be used to deploy web applications, manage dependencies, and scale worker processes.
