What is Self-Hosted Software?

Self-hosted software refers to applications you install and run on your own server, VPS, or home lab — giving you complete control over your data, privacy, and customisation. Instead of relying on third-party cloud services, self-hosting lets you be your own provider.

Why Self-Host?

Privacy – Your data stays on your infrastructure, not a vendor's servers.
Cost Savings – Avoid recurring SaaS subscription fees with one-time or free open-source solutions.
Customisation – Modify and extend software to fit your exact needs.
No Vendor Lock-in – Migrate, backup, or shut down on your own terms.
Reliability – Control your own uptime and SLAs.

Popular Self-Hosted Categories
