Why I Built ani-sync: The Zero-Buffering Terminal Anime Streamer with Multi-Cloud Sync

Description and use

ani-sync is a terminal anime player that eliminates buffering by using 64 parallel connections, RAM‑disk caching, and auto‑synchronizes progress across MyAnimeList, AniList, and Kitsu.

Problem

Streaming anime from a terminal is slow, requires manual scrobbling, and consumes heavy browser resources.

Outcome

ani-sync reduces buffering to 0 s, cuts RAM usage from 3 GB to ~30 MB, keeps CPU <5 % by GPU decoding, and automates multi‑platform progress sync.

Workflow

• 1. Install ani-sync via one‑liner or package manager
• 2. Search for anime with "ani-sync <anime>"
• 3. Stream with optional --skip for auto‑skip
• 4. Use "ani-sync continue" to resume last watched
• 5. Batch download with -d and episode range
• 6. Progress auto‑sync to MAL, AniList, Kitsu on episode finish

Evidence

64-Connection Parallel Swarm: By pulling 64 segments concurrently across multiple TCP sockets, entire 25‑minute episodes load in 3–5 seconds
