Dynacat is a self-hosted, configurable personal dashboard application forked from Glance. It aggregates content from dozens of external services — RSS/Atom feeds, Reddit, Hacker News, Twitch, YouTube, weather (Open-Meteo), financial markets (Yahoo Finance), Docker containers, media servers (Plex/Jellyfin/Emby/Navidrome), torrent clients, and DNS servers — into a single YAML-configured page layout. The backend is a Go HTTP server built on the standard library, serving server-rendered HTML templates with progressive enhancement via vanilla JavaScript, htmx, and SSE for live widget updates. It supports password-based and OIDC authentication, per-page access control, a CSS-variable theme system, and PWA/installability features. Architecturally, the codebase centers on a widget plugin system: each widget type implements a common lifecycle (initialize, update, render, optional request handling) registered in a factory. Shared infrastructure includes a disk-based image cache with proxy fallback, a singleflight-based shared HTTP request layer that deduplicates concurrent external fetches, a generic worker pool for parallel requests, and an SSE update loop. Configuration supports YAML includes, environment variable and Docker secret substitution, and hot-reload via fsnotify. The code is well-organized for a fork of this size: shared patterns are extracted into reusable helpers (generic singleflight, worker pool, custom YAML unmarshalers, and a standalone sysinfo package under pkg/), and focused unit tests cover auth and several widgets. Main caveats are large monolithic widget files (700–900 lines mixing HTTP, parsing, and rendering), duplicated fetch logic across the 'latest-media' and 'playing' widgets, and heavy reliance on many external APIs whose availability or rate limits can affect the dashboard. The project is actively maintained with frequent releases, GitHub Actions CI/CD, and a goreleaser setup for multi-arch Docker images.
