Best self-hosted open-source apps to deploy on Coolify

One of the main reasons engineering teams adopt Coolify is its catalog of more than 300 one-click Docker Compose service templates. Instead of spending two days writing boilerplate reverse-proxy rules, generating secrets, and wiring container networks, you can spin up a complete open-source tool in minutes.

Crucially, Coolify copies the template’s Docker Compose definition into your service at creation time—meaning later upstream catalog changes will not unexpectedly overwrite your running deployment.

Still, not all 300 templates belong in a business stack, and default one-click settings often need a few production tweaks. Below are the top-ranking open-source apps to deploy on Coolify, grouped by architectural layer, along with how we wire and harden them in client projects.

Overview: Top Coolify service templates for engineering & product teams

Category	Top Coolify Templates	SaaS Replaced	Key Production Hardening Step
Automation & Workflows	n8n (with Postgres + worker), Activepieces, Hatchet	Zapier, Make, Workato	Use the Postgres + Redis queue worker variant; set N8N_ENCRYPTION_KEY and external S3 backups
Backend & Databases	Supabase, PocketBase, Appwrite, PostgreSQL + pgvector / PostGIS	Firebase, Auth0 + managed DBaaS	Place stateful databases on a dedicated server node separate from build workloads
Headless CMS & Internal Apps	Directus (with PostgreSQL), Strapi, Ghost, Appsmith, Budibase, NocoBase	Contentful, Webflow, Retool	Mount persistent uploads to S3/MinIO rather than local container volumes
Privacy-First Analytics	Plausible Analytics, Umami, PostHog, Matomo	Google Analytics 4, Mixpanel	Bound ClickHouse/Postgres memory limits so analytics spikes cannot OOM-kill web apps
AI, LLMs & Vector Search	Open WebUI, LiteLLM, Dify, AnythingLLM, Qdrant, Chroma	ChatGPT Team, proprietary AI gateways	Put behind SSO/OAuth and connect to dedicated GPU inference or EU API gateways
Identity, Docs & Ops	Keycloak, Authentik, Docmost, Outline, Documenso / DocuSeal, Uptime Kuma, Grafana, Beszel, MinIO	Okta, Notion, DocuSign, Datadog	Isolate Uptime Kuma / monitoring on a separate node from the workloads it monitors

1. Workflow automation: n8n & Activepieces

n8n is consistently the #1 business service deployed on Coolify.

• Which template variant to pick: Coolify ships three n8n variants (default, with postgresql, and with postgres and worker). Skip the SQLite default for anything beyond personal testing. Choose n8n with PostgreSQL and Worker (Redis + queue mode) so webhook bursts and long-running AI agent steps do not block the main UI process.
• Integration idea: Connect n8n over Coolify’s internal Docker network directly to your PostgreSQL, Directus, or Nextcloud containers without traversing the public internet.

2. Backend-as-a-Service & spatial databases: Supabase, Appwrite, PocketBase & PostGIS

• Supabase: Coolify’s one-click Supabase stack spins up PostgreSQL, GoTrue (Auth), PostgREST, Realtime, Storage, Kong API Gateway, and Supabase Studio. Because the full stack runs ~10 containers, deploy it on a dedicated VPS (minimum 4 vCPUs / 8 GB RAM) and immediately configure automated S3 backups for the Postgres database and Storage buckets.
• PocketBase & TrailBase: When you want an ultra-fast, single-binary backend with embedded SQLite, real-time subscriptions, and auth that consumes less than 100 MB of RAM, PocketBase on Coolify is unbeatable for MVPs and internal tools.
• PostgreSQL + pgvector + PostGIS + Martin: For data-intensive products, we combine PostgreSQL AI backends and PostGIS geospatial platforms with Coolify’s Martin template (a blazing-fast Rust PostGIS vector tile server) to feed deck.gl maps.

3. Headless CMS, customer portals & low-code: Directus, Appsmith, Docuseal

• Directus (with PostgreSQL): Introspects any SQL schema and instantly provides a clean REST/GraphQL API plus a customizable data studio for operations teams. Configure Directus on Coolify to use MinIO or external S3 for asset storage so container redeploys remain stateless.
• Appsmith / Budibase / NocoBase: Ideal for building internal admin panels over your PostgreSQL databases in hours instead of weeks.
• Documenso & DocuSeal (with Postgres): Self-hosted open-source alternatives to DocuSign for legally binding PDF contract signing workflows, easily triggered via webhook from n8n or your CRM.

4. GDPR-friendly web & product analytics: Plausible & Umami

European teams frequently use Coolify to replace Google Analytics with cookie-free, GDPR-compliant analytics:

• Plausible Analytics (Community Edition): Powered by PostgreSQL and ClickHouse. Because ClickHouse is memory-hungry, always set explicit Docker memory limits (deploy.resources.limits.memory) in the Coolify Compose editor so background merges do not starve co-located services.
• Umami: A lighter-weight PostgreSQL-backed alternative when you want clean traffic and event metrics on a smaller server footprint.

5. Self-hosted AI & RAG orchestration: LiteLLM, Open WebUI, Dify & Qdrant

Coolify makes standing up the control plane of a self-hosted AI stack remarkably fast:

• LiteLLM Proxy: Deploy LiteLLM on Coolify as a unified OpenAI-compatible gateway that manages API keys, per-team token budgets, fallbacks, and routing across OpenAI, Anthropic, Mistral, and your own vLLM/Ollama GPU nodes.
• Dify & AnythingLLM: Visual RAG and agent workflow builders that connect to Qdrant or Chroma vector databases (also available as one-click Coolify templates) and Browserless (headless Chrome for web scraping) or Gotenberg (stateless PDF generation API).

6. Identity, knowledge wikis & observability: Keycloak, Docmost, Uptime Kuma & Beszel

• Keycloak or Authentik: Anchor your entire Coolify estate in single sign-on. Put Keycloak in front of Directus, Grafana, Outline/Docmost, and internal dashboards.
• Docmost & Outline: Fast, modern open-source alternatives to Notion and Confluence for engineering and company documentation.
• Beszel, Uptime Kuma, Dozzle & GlitchTip:
  • Beszel (and its lightweight agent) gives you clean CPU, RAM, disk, and Docker container metrics across all your Coolify servers.
  • Dozzle provides real-time container log search.
  • GlitchTip or Bugsink gives you self-hosted, Sentry-compatible error tracking without per-event overage fees.

4 production rules before relying on Coolify templates

1. Pin image tags: Change :latest in template Compose files to explicit semantic versions (e.g., n8nio/n8n:1.85.2) so a routine restart never triggers an unplanned major upgrade.
2. Separate build servers from database servers: Connect at least two servers in Coolify—run builds and preview deployments on a dedicated build VPS, and keep stateful production databases on an isolated node.
3. Verify S3 backup restores: Connect Coolify’s built-in database backup scheduler to Hetzner Object Storage, AWS S3, or Backblaze B2—and test restoring a dump into a staging container monthly.
4. Lock down the control plane: Never leave port 8000 exposed to the public internet without MFA, IP allowlisting, or a Cloudflare Access / WireGuard tunnel.
