Convert The Spire Reborn

Cross-platform media downloader and converter for 1,800+ sites

Cross-platform downloader and converter for the 1,800+ sites yt-dlp supports, built with Flutter and Dart. Downloads are self-healing: yt-dlp updates itself in the background, failed downloads retry through a bundled Deno runtime, and the app falls back across alternate API clients instead of just failing. Windows, macOS and Android, GPLv3. The Android build enumerates whole playlists itself, handling every shape of YouTube's continuation token so an 800 item playlist pages fully on a phone, takes downloads through a headless WebView JS challenge solver, runs a foreground torrent service Android will not kill, matches titles with CJK awareness, and keeps playing in the background with Bluetooth media controls. Localised into 18 languages.

Case study

How this site is built

No framework. A single Go binary serves everything: the site, the support chat, the API. It runs on a Raspberry Pi.

Chat storage is SQLite, not a flat file, after losing history once to exactly that. The migration was proven with a real test: send a message, kill the process mid-write, restart, confirm nothing's lost.

The chat itself is a hand-rolled WebSocket layer: rooms, moderation, reconnect with history replay, no library doing the hard part.

Styling is hand-written CSS with a small token system for light and dark mode, no CSS framework, no build step.

Previously built with Next.js and React as well, this site is deliberately not that. Happy to talk through the tradeoffs either way.

Writing

Not software, but part of the job. How these projects go down when you post them, and somewhere for other developers to say how it is going for them.
