Cap Self Hosting (Updated May 2025)

Self-hosting deployment options for Cap are currently being worked on. This includes a Dockerfile and also one-click deployment via Railway. Documentation on how to deploy will be released as soon as we make the Dockerfile and Railway deployment template stable. You will be able to take your self hosted URL and paste directly into the desktop app for direct, instant use.
