Open source alternative to Heroku, Railway, Render and DigitalOcean App Platform
Last verified
Deploy apps on your own server with CapRover, a self-hosted PaaS built on Docker, nginx, and Let's Encrypt. An alternative to Heroku, Render, and Railway.
CapRover turns a single $5 to $20 VPS into a host for multiple personal projects with separate domains, automatic HTTPS, and persistent databases. The one-click catalog handles PostgreSQL and Redis installs in seconds.
If you need guaranteed uptime SLAs, multi-region failover, or managed database backups, a commercial PaaS or managed database service is the safer choice.
Teams paying $50 to $200 per month for hosted PaaS infrastructure can move those workloads to a single VPS with CapRover handling HTTPS, routing, and deployments. The `caprover deploy` CLI fits directly into existing CI/CD pipelines.
If your team has no one comfortable managing a Linux server, the ops responsibility shifts to you. CapRover removes deployment complexity but not server administration.
CapRover's per-app domain management and one-click installs make it practical to run separate environments for different client projects on the same server. Each app gets its own subdomain and HTTPS certificate automatically.
Client projects with strict uptime requirements or security compliance audits may need dedicated isolated hosting rather than a shared VPS.
The one-click catalog includes PostgreSQL, MySQL, MongoDB, Redis, WordPress, and monitoring tools. Each runs as a persistent Docker container with volume mounts, accessible via the internal Docker network or an exposed port.
For production database workloads at scale, managed database services offer better backup automation and failover than a self-hosted Docker container.
Deploying a production app requires configuring nginx, obtaining SSL certificates, setting up reverse proxies, writing deployment scripts, and maintaining all of it. Commercial PaaS platforms like Heroku, Railway, Render, and DigitalOcean App Platform solve that configuration burden but charge a margin for doing so. A 2 GB production dyno on Heroku costs around $250 per month; the same compute on a VPS provider costs under $10. Most developers do not want to configure servers manually, but they also do not need to pay managed-cloud margins indefinitely.
Three apps each needing a web process, a background worker, and a small database can exceed $100 to $200 per month on hosted PaaS tiers that charge per process or per resource unit. The underlying VPS hardware is cheap; the automation layer is what costs money.
CapRover runs every app inside a Docker container with Docker Swarm managing orchestration across single or multi-node setups. You do not need to write Dockerfiles from scratch for common stacks: CapRover's captain-definition file lets you specify just the runtime and port.
Every domain added to an app gets a Let's Encrypt certificate issued and renewed automatically. HTTP-to-HTTPS redirects are enabled with a single checkbox in the web GUI. No certbot configuration, no nginx reload scripts.
CapRover ships with a catalog of pre-configured one-click installs including PostgreSQL, MySQL, MongoDB, Redis, WordPress, and dozens of other services. Each installs as a persistent Docker container with volume mounts pre-configured.
The `caprover deploy` CLI command bundles your source, builds the Docker image, pushes it to the registry, and deploys to the running container in a single command. Webhook-based deploys also work for CI/CD pipelines.
The nginx reverse proxy is fully configurable per app; you can paste a custom nginx config template that overrides the default. This covers custom headers, rate limiting, WebSocket upgrades, and other scenarios the default proxy cannot handle.
Adding a worker node to the cluster runs one SSH command. CapRover then distributes containers across nodes and balances traffic automatically. No Kubernetes or Helm required for horizontal scaling.
Both handle HTTPS automatically and support a CLI-based deploy workflow. The difference is hosting model: CapRover runs on a VPS you control, while Heroku is a fully managed cloud service with no self-hosting option.
| Feature | CapRover | Heroku |
|---|---|---|
| License | Apache 2.0 + fair-code | Proprietary |
| Self-hosting | Yes | No |
| Pricing | VPS cost only | $7+/dyno/month |
| HTTPS | Automatic (Let's Encrypt) | Automatic (included) |
| Horizontal scaling | Docker Swarm | Heroku dynos |
| One-click services | Yes (open source catalog) | Yes (Heroku add-ons, paid) |
CapRover is the better choice for developers currently paying Heroku for standard web app hosting. A single VPS running CapRover can replace multiple Heroku dynos at a fraction of the cost. The caprover deploy CLI fits into existing pipelines the same way git push heroku does.
Heroku remains a better fit when your team needs Salesforce-tier compliance certifications, the full Heroku add-on ecosystem for managed third-party services, or zero infrastructure responsibility. Heroku's managed database add-ons include automated backups and failover; CapRover's database containers require you to configure backups yourself.
Render is a modern PaaS with managed databases, automatic static site deploys, and preview environments for every pull request. CapRover does not include built-in preview environments and requires managing the underlying server.
| Feature | CapRover | Render |
|---|---|---|
| License | Apache 2.0 + fair-code | Proprietary |
| Self-hosting | Yes | No |
| Pricing | VPS cost only | $7+/service/month |
| PR preview environments | No | Yes |
| Static site hosting | Yes (via nginx) | Yes (built-in CDN) |
| Managed databases | No (Docker containers) | Yes |
Render is the better choice if your workflow depends on per-pull-request preview environments, you need managed PostgreSQL with automated backups, or your team has no one to manage a server. CapRover wins on cost and data control for teams already comfortable with VPS administration who want to host multiple services without per-service billing.
Install the CLI to deploy apps; CapRover's server component runs on your infrastructure via Docker.
```bash
npm install -g caprover
caprover deploy
```Yes. The core platform is free to self-host on your own server, including for commercial internal use, under an Apache 2.0 base license with additional fair-code terms. You pay only for the VPS you run it on. Paid features exist but are not required for standard deployments.
CapRover supports any application that runs in a Docker container. The official documentation explicitly names Node.js, Python, PHP, Ruby, Go, Java, and .NET. It also includes a one-click catalog for databases (PostgreSQL, MySQL, MongoDB, Redis) and popular services like WordPress.
CapRover replicates the Heroku deployment experience, including CLI deploy, per-app routing, and automatic HTTPS, on a server you own. Heroku charges per dyno; CapRover charges nothing beyond VPS costs. The trade-off: you manage the server yourself, including OS updates, backups, and handling hardware failure.
Yes. CapRover uses Docker Swarm for clustering. Adding a worker node runs one SSH command; CapRover then distributes containers across nodes and load-balances traffic automatically. This covers most small-to-medium workloads without requiring Kubernetes.
CapRover uses Apache 2.0 as its base license with additional fair-code terms. Self-hosting for any purpose including commercial internal use is permitted. Paid features cannot be modified without a written agreement, and redistribution of a paid version requires one. Modifications to free features must be released as free and open-source software.
