Open-source alternatives to Heroku
9 open-source projects are offered as replacements for Heroku. Coolify is the most starred. Running one yourself trades the subscription for your own hosting and upkeep, so the table below leads with what decides that trade: whether the project is alive, what its licence lets a business do, and whether there is a container command to start from.
