A reference of self-hostable open-source applications by category. See current deployed services for what's actually running.

From running on constrained hardware (2GB RAM on a VPS, ~7GB on current server):

• Shared database: One PostgreSQL instance, multiple databases/users — avoids spinning up separate DB containers per service
• Alpine images: Prefer Alpine-based tags (e.g. postgres:16-alpine) for smaller footprint
• Memory limits: Always set mem_limit in docker-compose to prevent runaway containers
• Network segmentation: Separate Docker networks by function (caddy_net, db_net, monitoring_net)

See Docker Infrastructure for patterns.
