Free and open-source Heroku alternatives

Heroku (Platform as a service to deploy and run apps) is a commercial product. These 3 tools do the same job and are free to use or to self-host.
Short answer: the best free alternatives to Heroku are Coolify, Dokploy and CapRover. Heroku starts at $5/mo per dyno (Eco). Self-hosting is free; you pay only for the server (a small VPS is about $4–6/mo). Licenses and prices checked 2026-10-01.
