This repository provides a self-hosted platform for deploying and managing web applications on a single server. It integrates Cloudflare for public access via tunnels, Tailscale for secure private access, Docker and Kamal for containerized deployment, and GitHub for webhook-triggered updates. The system consists of a daemon that handles incoming webhooks and manages deployments, and a CLI for initial setup and ongoing administration. Applications are deployed with zero-downtime using Kamal, and the platform automates the configuration of DNS, TLS, and service discovery. The architecture centers around a single Go binary that operates in two modes: as a background service (singleserverd) to process GitHub webhooks and orchestrate deployments, and as a command-line interface (singleserver) for users to configure the platform, add applications, and manage resources. State is stored in files under /etc/singleserver (configuration, credentials) and /srv (source code, storage, backups). The platform emphasizes simplicity and automation, aiming to reduce the operational overhead of running multiple applications on a single VPS. Key features include an interactive setup wizard for connecting provider accounts, automatic DNS and TLS configuration via Cloudflare, secure access through Tailscale Funnel, and a built-in diagnostics tool (doctor) to verify system health. The design prioritizes reliability through atomic file updates, context-aware command execution, and comprehensive error handling. The project includes extensive unit tests and end-to-end validation scenarios that exercise real integrations with the supported services.
