5 Self-Hosted Heroku Alternatives for Deploying Your Apps (2026)

Contains affiliate links. Disclosure.

Heroku's free tier was discontinued in 2022 and paid plans now start at $5/dyno/month — with no included databases, storage billed separately, and costs that compound quickly as you add apps and workers. Self-hosted PaaS tools replicate the Heroku experience (Git push to deploy, automatic SSL, web UI, database provisioning) on a VPS you control, at a fraction of the cost.

Need a self-managed VPS?

Coolify and Dokploy both run on a Liquid Web Self-Managed VPS from $3.50/mo.

The tools below cover two categories: true self-hosted PaaS platforms (Coolify, Dokploy, Caprover, Piku) that you install on your own VPS, and one managed alternative (Fly.io) for context — included because it is the most common non-self-hosted Heroku replacement, though it cannot be self-hosted.

Coolify

Coolify is the most popular self-hosted Heroku alternative in active development. A single install command bootstraps a Docker Swarm cluster, a web dashboard, automatic SSL via Let's Encrypt, and support for deploying from any Git provider, Docker images, or Docker Compose files. It includes one-click provisioning for PostgreSQL, MySQL, Redis, MongoDB, and over 280 template apps.

• Stars: ~52.2k
• License: Apache-2.0
• Stack: PHP (Laravel) + Docker Swarm + PostgreSQL + Redis
• Idle RAM: ~800 MB
• Minimum VPS: 2 GB RAM (4 GB recommended for multi-app use)
• Setup guide: Self-Host Coolify

Coolify is the right choice for teams deploying multiple apps on a shared server with a clean UI and active community support. Its "Source" system supports GitHub, GitLab, Gitea, and Bitbucket repositories with automatic build-and-deploy webhooks — matching Heroku's git push heroku main workflow but with zero per-dyno pricing.

Dokploy

Dokploy is a newer self-hosted PaaS that positions itself as a lighter Coolify alternative. It uses Docker Compose for deployments rather than Docker Swarm, which makes it simpler to reason about and debug. The web UI is clean and modern, and it covers the core PaaS workflow: Git-based deployments, SSL, domain routing, and database provisioning.

• Stars: ~31k
• License: Apache-2.0
• Stack: Node.js + Docker Compose + PostgreSQL + Traefik
• Idle RAM: ~600 MB
• Minimum VPS: 2 GB RAM
• Setup guide: Self-Host Dokploy

Dokploy's lighter footprint (600 MB vs 800 MB idle for Coolify) and simpler architecture make it attractive for solo developers or small teams with straightforward deployment needs. It does not yet have Coolify's breadth of one-click templates or multi-server cluster support, but its faster iteration cycle means the gap is narrowing. If you prefer Traefik over Caddy as your reverse proxy, Dokploy's native Traefik integration is a meaningful advantage.

Caprover

Caprover is a Docker Swarm-based PaaS with a long track record — it predates both Coolify and Dokploy and has a stable, mature feature set. One-click app templates (over 100 community-contributed), automatic SSL, multi-server clustering, and Git push deployments are all supported. It is particularly popular in the homelab community.

• Stars: ~13k
• License: Apache-2.0
• Stack: Node.js + Docker Swarm + Nginx
• Idle RAM: ~500 MB
• Minimum VPS: 2 GB RAM
• Setup guide: No guide on this site yet — official Caprover getting started docs

Caprover's main downside in 2026 is activity level — commit frequency has slowed significantly compared to Coolify and Dokploy. The core functionality is stable and unlikely to regress, but new features and integrations lag behind the newer tools. For teams that value stability over cutting-edge features and want a proven Docker Swarm PaaS, Caprover remains a solid choice.

Piku

Piku takes a radically different approach: no web UI, no Docker, no dashboard. It implements a Heroku-style git push workflow using a tiny shell script that runs on your server. Push your code, Piku detects the runtime (Python, Node.js, Go, Ruby, and more via Procfiles), builds it, and starts it as a systemd service. SSL is handled via Caddy or Nginx.

• Stars: ~5k
• License: MIT
• Stack: Shell + Python + uwsgi/nginx + systemd
• Idle RAM: ~50–100 MB (Piku itself is negligible; your apps define the footprint)
• Minimum VPS: 1 GB RAM (512 MB for very small deployments)
• Setup guide: No guide on this site yet — official Piku documentation

Piku is ideal for solo developers who want git push deploys on a $3.50/mo VPS without any PaaS overhead. There is no web UI — everything is managed via SSH and git remote commands. This simplicity is a feature: there is no dashboard to break, no scheduler to maintain, and no Docker daemon to debug. The trade-off is that it does not provision databases or manage SSL certificates automatically — those are manual tasks.

Fly.io (managed, not self-hostable)

Fly.io is the most-recommended managed Heroku alternative and deserves mention for context, even though it cannot be self-hosted. It runs your Docker containers on its global edge network, provides native PostgreSQL and Redis add-ons, and has a CLI-first workflow that feels closer to Heroku than any other managed platform.

• Pricing: Free tier available; paid from ~$1.94/mo per shared CPU VM
• Self-hostable: No
• Best for: Teams that want Heroku ergonomics without managing a VPS

Fly.io is worth considering alongside self-hosted options if you prioritize geographic distribution (deploying your app in multiple regions) or want zero infrastructure management. The cost per app is lower than Heroku's paid tiers but higher than running Coolify or Dokploy on a shared Liquid Web VPS where multiple apps share a single server cost.

Picking the right tool:

• Most features, largest community: Coolify on a 4 GB Liquid Web VPS
• Lighter footprint, cleaner UI: Dokploy on a 2 GB Liquid Web VPS
• Stable, proven Docker Swarm PaaS: Caprover
• Minimal git push deploys, solo developer: Piku on a 1 GB VPS
• No infra management, global edge: Fly.io (managed)

Frequently Asked Questions

Yes — that is the primary use case. Both Coolify and Dokploy act as multi-app PaaS platforms: you deploy as many apps as your VPS RAM and CPU can support. A 4 GB Liquid Web VPS running Coolify (800 MB idle) leaves roughly 2.5 GB for your applications after OS overhead. A typical Node.js or Python app uses 100–300 MB idle, meaning you can comfortably run 8–12 small apps on a single 4 GB VPS.

Yes. Coolify uses Docker Swarm's rolling update strategy by default, which brings up the new container before stopping the old one. The Traefik/Caddy proxy switches traffic only after the new container passes its health check. Zero-downtime deploys require a health check endpoint in your application — Coolify respects Docker HEALTHCHECK directives. Dokploy offers a similar rolling update mechanism via Docker Compose.

A Liquid Web Self-Managed VPS starts at $3.50/mo (1 GB RAM) and scales to $14/mo (4 GB RAM) — pricing verified at liquidweb.com as of 2026-05-03. Running 5 small Node.js apps on Heroku's Eco dynos ($5/dyno/mo) plus a Postgres mini add-on ($5/mo) costs $30/mo. The same 5 apps on Coolify on a 4 GB Liquid Web VPS cost $14/mo total — roughly 2× cheaper, with no per-app pricing and no separate database add-on costs.
