For a team of 10-20 people, a Contabo Cloud VPS 4 handles it comfortably. Nextcloud is available as a free 1-click add-on during VPS or VDS provisioning on Contabo \u2014 installation, SSL, and initial configuration are handled automatically.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">If pure file sync is all you need, Seafile is a faster and simpler alternative with excellent desktop clients. For team knowledge bases and documentation, Docmost and Outline are the two most popular Notion\/Confluence replacements \u2014 both run as single Docker containers and work well on a shared VPS.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Photos and Media<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Immich has become the breakout story of the self-hosted community over the last two years. It offers automatic phone backup, face recognition, smart search, and a mobile app that genuinely rivals Google Photos in daily usability. The trade-off is resource requirements: the machine-learning components need 2+ GB of RAM, making it better suited to a Cloud VPS 4 or above than a minimal instance.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Jellyfin is the open-source media server standard for film and TV libraries \u2014 it handles transcoding, remote access, and multi-user libraries without Plex&#8217;s server-pairing requirements or premium features paywalls. Paperless-ngx is worth highlighting for document-heavy workflows: it combines OCR, tagging, and search into a document management system that&#8217;s particularly well-suited to GDPR-compliant document retention \u2014 prominent in both the German and Spanish responses for exactly this reason.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Security and Passwords<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Vaultwarden is the practical starting point for self-hosted password management. It&#8217;s a Rust-based reimplementation of the Bitwarden server protocol that runs on roughly 256 MB of RAM from a single Docker container, with no license key required. All official Bitwarden client apps \u2014 desktop, mobile, and browser extensions \u2014 work with a Vaultwarden server, making migration seamless.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">WireGuard is the standard for self-hosted VPN, securing remote team connections with minimal overhead compared to older protocols. It&#8217;s available as a free 1-click installation on any Contabo VPS or VDS \u2014 the installation handles peer configuration and QR-code provisioning automatically. For teams that need single sign-on, Authentik has emerged as the most popular self-hosted identity provider.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Automation and AI<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">n8n is the most widely recommended self-hosted workflow automation platform in 2026 \u2014 it replaces Zapier and Make with no per-execution pricing, a visual workflow builder, and native AI node support for integrating local or cloud LLMs. Free 1-click installation on Contabo VPS and VDS. Activepieces is a newer alternative with a cleaner interface that&#8217;s gaining traction.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Open WebUI has become the standard self-hosted interface for running local AI models via Ollama \u2014 it provides a ChatGPT-like interface for Llama, Mistral, and other models running on your own hardware. Particularly prominent in German and Spanish responses as local AI inference has entered mainstream self-hosting practice. Requires significant RAM (8+ GB for useful models); pairs well with Contabo&#8217;s Cloud VPS 8 (24 GB) or Cloud VDS for GPU-accelerated inference.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Dev Tools and Git Hosting<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\"><a href=\"https:\/\/contabo.com\/blog\/gitea-vs-forgejo\/\">Forgejo and Gitea<\/a> are the two most popular self-hosted Git platforms. Forgejo is the community fork of Gitea \u2014 for most new deployments, Forgejo is the recommended choice as it has broader community governance. Both are extremely lightweight (256 MB RAM) and include issues, wikis, pull requests, and CI\/CD integration. GitLab CE is the heavier alternative when you need built-in CI\/CD pipelines, a container registry, and deeper DevOps tooling \u2014 available as a free 1-click installation on Contabo, but requires at least 4 GB RAM for stable operation.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Monitoring, Dashboards, and Infrastructure<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Uptime Kuma is the universal starting point: lightweight monitoring with a polished UI, 256 MB RAM, and a five-minute setup. It monitors URLs, ports, and SSL certificates and sends alerts via Telegram, Discord, email, and more. Beszel is a newer server monitoring tool gaining rapidly \u2014 it tracks CPU, RAM, and disk per container, and appeared prominently in both German and Spanish responses as a modern alternative to Grafana\/Prometheus for single-server setups.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><a href=\"https:\/\/contabo.com\/en\/coolify-vps\/\">Coolify <\/a>has emerged as the most popular open-source PaaS in 2026 \u2014 it&#8217;s a self-hosted Heroku or Vercel alternative that handles Git-to-deploy pipelines, SSL, and Docker management from a single dashboard. Particularly prominent in German responses (appearing in 60% of DE recommendations). For teams that prefer a traditional server control panel over Docker-based management, HestiaCP is the most popular open-source cPanel alternative \u2014 widely used in Spanish-language markets for managing multiple domains, databases, and email from a web interface.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Analytics and Privacy<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Plausible and Umami are the two dominant Google Analytics replacements. Both are cookieless, <a href=\"https:\/\/gdpr-info.eu\/\" rel=\"nofollow\">GDPR<\/a>-compliant by design, and run comfortably on 512 MB RAM. Umami has a slightly lighter footprint and a simpler setup; Plausible has a more polished interface and slightly more advanced filtering. Matomo (formerly Piwik) remains the choice when you need GA-style event tracking or advanced segmentation.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Running This Stack on a Contabo VPS<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Most self-hosted apps run from Docker Compose files, meaning multiple apps can share one VPS with minimal overhead.

These appear in the large majority of self-hosting recommendations and form the core of most starter stacks.<\/p> <\/div> <div class=\"schema-faq-section\" id=\"faq-question-1785315243958\"><strong class=\"schema-faq-question\">What VPS specs do I need to run self-hosted apps?<\/strong> <p class=\"schema-faq-answer\">For a typical starter stack (Vaultwarden, Uptime Kuma, Gitea), 1-2 GB of RAM is sufficient. For a small team stack with Nextcloud, n8n, and a few supporting apps, 4-8 GB of RAM is the practical range. Memory-heavy apps like Immich (2+ GB for ML) or AI inference with Open WebUI and Ollama (8+ GB) need larger instances.

Vaultwarden gives you a useful, password-manager with immediate practical value; Uptime Kuma teaches monitoring fundamentals with a polished interface.<\/p> <\/div> <div class=\"schema-faq-section\" id=\"faq-question-1785315265261\"><strong class=\"schema-faq-question\">Can I replace all my SaaS tools with self-hosted alternatives?<\/strong> <p class=\"schema-faq-answer\">Most productivity SaaS \u2014 file storage, password management, analytics, automation, project management, and team chat \u2014 have mature self-hosted equivalents in 2026. The practical caveat is operational: you are responsible for updates, backups, and security.
