Open Source Heroku Alternatives

Platform-as-a-service pricing scales with your success, and moving off one usually means rebuilding the deployment story from scratch. Coolify offers the same convenience on your own hardware, standing in for Heroku, Netlify and Vercel while the machines and the bills stay yours.

Coolify needs nothing more than an SSH connection to a machine. From there it manages virtual private servers, bare metal boxes and Raspberry Pis alike, deploying applications, databases and other services onto whatever you point it at.

Two properties matter most for anyone weighing the switch.

• No vendor lock-in: configuration for every resource is written to your own server.
• Survivable exit: stop using Coolify and your resources keep running, minus the automation.
• Any hardware: one tool covers a rented VPS, a colocated server and a Raspberry Pi.
• One-line install: a shell script published by the project sets up an instance on a fresh machine.

The suggested layout puts Coolify on its own server, roughly the price of a small VPS each month, with separate servers for the resources it deploys. A paid cloud version hosts the control plane instead, adding high availability and email notifications, and the project stays funded through sponsorships rather than paywalled features.

Dokploy is a free platform as a service you host yourself. It closes the gap between a bare VPS and a managed host, giving deployments, databases, backups and monitoring on a server you already pay for.

Installation is a single shell command run on the VPS. Traefik integration handles routing and load balancing automatically, Docker Compose is supported natively for multi service applications, and Docker Swarm scales an application across several nodes.

The dashboard covers the operational work that follows a deployment.

• Applications: deploy Node.js, PHP, Python, Go, Ruby and other stacks.
• Databases: create and manage MySQL, PostgreSQL, MongoDB, MariaDB, libsql and Redis instances.
• Backups: schedule database backups to an external storage destination.
• Monitoring: watch CPU, memory, storage and network usage for every resource.
• Notifications: report deployment success or failure to Slack, Discord, Telegram or email.
• Templates: install open source projects such as Plausible, Pocketbase and Cal.com in a single click.

A CLI and an API cover the same ground as the interface for anyone scripting their workflow, and multi server support manages deployments on remote machines from one place. A hosted cloud version exists for teams that would rather skip the installation entirely.

Dokku describes itself as a Docker powered mini-Heroku and the smallest platform-as-a-service implementation you have seen. It turns one fresh virtual machine into somewhere to deploy applications, without the operational weight of a full orchestration stack underneath it.

Installation is deliberately short. Fetch the bootstrap script for the current stable release, run it with sudo and a matching version tag, then set the global domain and register the SSH keys allowed to deploy. A keypair already present on the machine is imported automatically during installation, and otherwise keys are added afterwards through the ssh-keys command.

A few practical constraints decide where Dokku can run.

• Operating systems: Ubuntu 22.04 or 24.04, or Debian 11 and later, on amd64 or arm64.
• Fresh machine: The installer expects a clean VM rather than a server already busy with other services.
• SSH access: Deployment identity comes from keypairs registered with the platform.
• Unattended install: A documented path exists for people provisioning servers automatically.
• Upgrades: Moving between releases follows its own documented procedure.

Full documentation, including advanced installation, lives online rather than in the README. Questions go to GitHub issues, the troubleshooting guide or the dokku channel on Gliderlabs Slack. The code is MIT licensed and originated with Jeff Lindsay, and pull requests are welcomed as conversation starters even when they are not merged as written.

Encore turns infrastructure into something you declare in application code. A database, a Pub/Sub topic or a storage bucket exists because you constructed the object in Go or TypeScript, which removes the standing gap between what the code expects and what the environment was manually given.

There are two parts. The open source infrastructure SDK covers databases, Pub/Sub, object storage, caches, cron jobs and secrets, and one run command starts the whole system locally with real Postgres, real Pub/Sub semantics and distributed tracing. The managed platform that orchestrates cloud infrastructure is optional, and you can provision with Terraform instead.

Each declaration becomes a node in an application graph that maps to concrete services per environment.

• SQL databases: Postgres locally, RDS on AWS, Cloud SQL on GCP.
• Pub/Sub: NSQ locally, SNS with SQS on AWS, Cloud Pub/Sub on GCP.
• Object storage: the local filesystem, S3, or Google Cloud Storage.
• Preview environments: an ephemeral environment per pull request, optionally with a branched database.
• Deploys: the graph is diffed against the environment, missing resources are provisioned, and IAM is scoped from the code paths.

Adoption does not require a rewrite. New services can run beside an existing system and integrate over APIs, and Encore deploys into a Kubernetes cluster or VPC you already have.

The limits are stated up front. Services must be TypeScript or Go, with Python still to come, and automated provisioning covers AWS and GCP only, though a Docker build works on any provider.

/dev/push is a self-hostable stand-in for Vercel, Render and Netlify. You push to GitHub, it builds and deploys, and the whole thing runs on a server you rent rather than a platform that meters your builds and owns your domains.

Anything that runs on Docker can be deployed, which puts Python, Node.js and PHP projects on equal footing. Default runner and preset definitions ship in a registry directory that is copied into the data directory during install and update, and the catalog format and its override rules are documented alongside them.

The platform handles what a small team needs around a deploy.

• Git-based deployments: push to deploy from GitHub, with zero-downtime rollouts and instant rollback.
• Environment management: multiple environments with branch mapping and encrypted environment variables.
• Real-time monitoring: live, searchable build and runtime logs.
• Custom domains: your own domains with automatic Let's Encrypt certificates, using the default challenge or a DNS challenge through Cloudflare, Route 53, Google Cloud, DigitalOcean or Azure.
• Team collaboration: role-based access control with invitations and per-role permissions.

Installation is one script on a fresh Ubuntu 20.04 or Debian 11 server with SSH and sudo, after which you create a GitHub App for login and repository access, edit the environment file, point an A record and a wildcard A record at the server, and start the systemd service. An email provider is needed for login and invitation mail. Shell scripts in the repository cover backup, restore, updates, migrations, status and uninstall.
