Heroku alternatives: 3 free & open-source picks
Curated, verified, and actually free. No trials, no crippled tiers. Star counts and last-activity dates checked by hand, not scraped and forgotten.
Heroku on your own server, including Git deploys, TLS, logs, databases, and scheduled backups.
licenseApache-2.0
runsyour machine or their cloud
installCoolify Cloud signup or one-line install script on a fresh Linux server
dataSelf-hosted control data is in an internal PostgreSQL container; deployed apps and databases remain in Docker containers, volumes, and configuration on the user's servers
the catch vs HerokuCoolify recreates Git deploys, TLS, logs, and databases, but the VPS, operating-system patching, backups, uptime, and incident response now belong to you rather than Heroku.
setupA VPS with root SSH access, open ports, DNS, and responsibility for server patching and application-data backups

A newer self-hosted PaaS for apps and databases, with previews, TLS, logs, and backups in the same control plane.
licenseApache-2.0
runsyour machine or their cloud
installDokploy Cloud signup or one-line install script on a Linux VPS
dataDokploy metadata is stored in PostgreSQL; application and database data lives in Docker named volumes or bind mounts on the deployment servers, with optional S3 backups
the catch vs HerokuDokploy offers a modern self-hosted PaaS, but it lacks Heroku's provider-managed dynos, add-on marketplace, support, and hands-off infrastructure.
setupA VPS with at least 2 GB RAM, free ports 80/443/3000, DNS, and ongoing Docker/server administration

The original tiny Heroku-on-one-box; excellent once you are comfortable treating a server like a pet.
licenseMIT
runsyour server
installBootstrap script on a fresh supported Ubuntu or Debian VM, then add an SSH key and domain
dataApplication images, configuration, logs, and persistent Docker volumes live on the user's server; service data lives in installed database-plugin volumes
the catch vs HerokuDokku is the closest small Heroku-shaped experience, but it is command-line-first and turns dyno, router, database, backup, and host failures into your own pager duty.
setupA fresh Linux VM, sudo/SSH competence, DNS, and command-line-only administration

People still pay for Heroku because hosting products sell an operations team and failure-domain diversity, not merely a deploy button. The recurring cost buys patching, certificates, isolation, secrets, builds, deploys, logs, metrics, backups, capacity, incidents, and security response, not just the visible interface. If none of that applies to you, any pick above saves $84 a year.
Is there a free alternative to Heroku?
Yes: Coolify, Dokploy, Dokku. Every tool on this page is either open source or genuinely free to use long-term: no trials, no crippled tiers.
Should I just build my own Heroku?
Our verdict is NO TANTO. A consolation build is possible, but the paid product's decisive value sits outside a solo rebuild. For Heroku, deploy one containerized app with logs and a managed reverse proxy on a user server. The hard boundary is managed runtime, add-ons, buildpacks, databases, support, and operational maturity, plus infrastructure scale, operations, and reliability. If you'd rather build, the exact one-shot prompt is free at puedovibecodearlo.app/heroku-basic.
