Heroku alternatives: 3 free & open-source picks
Compare recorded free and open-source options, their capabilities and operating requirements. Source dates are shown below; licenses, hosted limits and project activity can change.
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. The recorded subscription totals $84 a year before any costs of an alternative.
Questions about these alternatives
Is there a free alternative to Heroku?
Yes: Coolify, Dokploy, Dokku. These are recorded free or open-source options. Compare their feature limits, licenses, hosting costs and current availability before choosing.
Should I just build my own Heroku?
Our verdict is NOT REALLY. 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. Review the scope, implementation prompt and trade-offs in the Heroku build guide.
