Open-source alternatives to Firebase
7 open-source projects are offered as replacements for Firebase. Supabase 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.
