Your own Heroku or Vercel on a dedicated server — Dokploy is the open-source PaaS that replaces cloud platform subscriptions with a single dashboard you control. Point it at a Git repository or a Docker image, and it builds and deploys the application using Dockerfiles, Nixpacks, or Heroku/Paketo buildpacks. Traefik handles reverse proxying, routing, load balancing, automatic Let's Encrypt SSL, and HTTP/3. Databases — MySQL, PostgreSQL, MongoDB, MariaDB, libsql, and Redis — provision from the UI with automated backups to any S3-compatible destination. Complex multi-service applications deploy through native Docker Compose support, and multi-node scaling uses Docker Swarm. The web dashboard covers environment variables, volumes, resource limits, real-time CPU/memory/network monitoring, and deployment logs, with a CLI and REST API for automation. Deploy notifications go to Slack, Discord, Telegram, or email. One-click templates install common open-source tools, and a single control plane can manage deployments across multiple remote servers. Because everything is standard Docker, there is no lock-in: Dockerfiles, Compose files, and data volumes work anywhere else Docker runs. The push-to-deploy workflow of a $20/seat cloud PaaS, running on a dedicated VPS with guaranteed CPU, RAM, SSD, and full root access — no per-app, per-environment, or per-seat fees regardless of how many applications you deploy. 26,000+ GitHub stars.

With over 4,300 GitHub stars and a v3 release adding built-in user management, team views, and multi-language support, Kubero has established itself as the most feature-complete open-source Heroku alternative running natively on Kubernetes. The platform operates as a Kubernetes operator with two containers — kubero-ui and the operator — storing all state in etcd without an external database. Developers push code via Git integration with GitHub, GitLab, Bitea, or Gitea, and Kubero automatically builds using Buildpacks, Nixpacks, Runpacks, or Dockerfiles, then deploys to the configured domain with SSL via cert-manager. CI/CD pipelines support up to four staging environments — review, test, staging, and production — with per-stage environment variable isolation and ephemeral review apps that spin up on pull request open and tear down on close. The template catalog includes over 170 pre-configured applications like WordPress, Grafana, and PostgreSQL deployable in one click, while managed add-ons provide highly available PostgreSQL, Redis, MySQL, Kafka, CouchDB, Elasticsearch, and MongoDB alongside your applications. Security features include Trivy vulnerability scanning, GitHub and OAuth2 single sign-on, basic auth, and a role-based permission system with API tokens.

With over 32,000 GitHub stars and a decade of production use since 2013, Dokku is the original self-hosted Heroku alternative — a Docker-powered PaaS that turns any single Ubuntu server into a full application platform with a simple git push. Deploy applications written in Node.js, Python, Ruby, Go, Java, PHP, Scala, and Clojure using Heroku-compatible buildpacks, Cloud Native Buildpacks via pack-cli, standard Dockerfiles, or pre-built Docker images, with automatic language and framework detection handling the rest. Every deployment runs through zero-downtime checks that health-test new containers before routing traffic via the built-in Nginx reverse proxy, which handles virtual host configuration, WebSocket proxying, and HTTP/2 support automatically. The official plugin ecosystem provides managed datastores including PostgreSQL, MySQL, MariaDB, MongoDB, Redis, RabbitMQ, and Elasticsearch, each provisioned with a single CLI command and linked to apps via environment variables. Automated TLS certificates arrive through the Let's Encrypt plugin with auto-renewal, while persistent storage volumes, cron job scheduling, user ACL management, and process scaling round out the platform capabilities. The entire system is CLI-driven — no web dashboard — keeping resource overhead minimal enough to run multiple applications on a $5/month VPS. Dokku also supports Lambda function builds, custom builder plugins, and app.json-based healthcheck configuration for advanced deployment workflows. Running on a dedicated VPS on RepoCloud with guaranteed CPU, RAM, and SSD, full root SSH access, and a browser serial console. MIT licensed.

With over 15,000 GitHub stars and nearly nine years of active development, CapRover is the self-hosted PaaS that replaces Heroku's pricing with your own infrastructure while keeping the deploy-and-forget simplicity. The web dashboard manages application lifecycle from deploy through scaling — configure custom domains, environment variables, persistent volumes, instance counts, and nginx templates without touching config files or SSH. The CLI tool enables scriptable deployments with a single command from your terminal or CI/CD pipeline, while webhook-based deployment triggers automated builds from Git pushes. The one-click app marketplace provides over 100 pre-configured services including WordPress, Ghost, PostgreSQL, MySQL, MongoDB, Redis, Grafana, Portainer, and dozens more, each deployed as a Docker container with volumes and environment variables preconfigured. Automatic HTTPS provisions and renews Let's Encrypt certificates for every custom domain with one-click HTTP-to-HTTPS redirects. Under the hood, Docker Swarm orchestrates containers across multiple nodes for horizontal scaling and load balancing, while nginx handles routing with fully customizable EJS-generated configuration templates per application. Deployment supports four methods: CLI push, tarball upload through the web UI, Docker image reference, and Git repository connection. The build system supports Dockerfiles, captain-definition files with build packs, and direct Docker image pulls. NetData integration provides real-time server monitoring dashboards.

OpenRun replaces the patchwork of CI/CD pipelines, reverse proxies, and identity providers that teams typically assemble when deploying internal tools, offering declarative GitOps-based deployment of web applications to Docker, Podman, or Kubernetes from a single self-hosted Go binary. Point it at a Git repository and it builds containers from AppSpec templates, routes requests by domain or URL path, provisions TLS certificates automatically, and scales idle applications to zero when unused. Blue-green staged deployments promote new versions through development, staging, and production environments with atomic rollback across multiple apps simultaneously. Every deployed application inherits SSO authentication through OAuth, OpenID Connect, or SAML providers alongside role-based access control, all configured once at the platform level rather than per app. Service bindings provision isolated PostgreSQL, MySQL, SQLite, or Redis credentials for each application, while Litestream integration replicates SQLite databases to S3 for automatic disaster recovery. The management console provides a web interface for monitoring containers, reviewing audit logs, configuring syncs, and managing server operations. AppSpec templates handle Streamlit, Gradio, FastAPI, Flask, and FastHTML projects out of the box, deploying existing Python applications without requiring custom Dockerfiles.

Tell an AI agent to deploy your app and watch it actually happen. Nixopus connects to your GitHub repo, analyzes the codebase to detect your framework, generates the right Docker configuration, resolves dependency conflicts, and ships the whole thing to your server with HTTPS enabled. When something breaks, the agent reads the logs, creates a pull request with a fix, and redeploys without waking you up. The chat interface lets you deploy, add custom domains, check logs, roll back, and troubleshoot in plain English from the web dashboard or directly from your VS Code or Cursor editor. Extensions bring one-click installs for 100+ self-hostable apps like Appwrite, Excalidraw, and Ollama, each showing you exactly what it runs on your server before installation. Connect multiple servers and monitor CPU, memory, disk, and running containers across your entire fleet from a single dashboard with draggable widget layouts. The built-in terminal opens SSH sessions right in the browser with split-pane support, so you can watch logs in one pane while running commands in another. Framework detection covers Next.js, Django, Rails, Go, FastAPI, and anything else that fits a container image. Every deployment gets automatic TLS via Caddy with Let's Encrypt certificates provisioned and renewed silently. Previous container images are retained so rollbacks skip the rebuild step entirely. Deploy on a dedicated VPS on RepoCloud with guaranteed CPU, RAM, and SSD, full root SSH access, and a browser serial console. AGPL-3.0 licensed.
