dcd-telegram: A 3.5 MB Rust Drop-in for Claude Code's 100 MB Telegram Plugin

The Problem If you use Claude Code with the official Telegram channel plugin, you've probably hit one of these: "Channels are not currently available" ( #36503 , 24+ comments) Bot shows "typing" but never replies ( #37933 ) Plugin stops after the first turn ( #36477 ) Zombie processes keep polling after session ends , causing 409 Conflict on the next launch The official plugin runs on Bun -- a JavaScript runtime. It works, but it's heavy: ~100 MB RAM per instance, 2-3 second startup, and it doesn't clean up after itself. If you run multiple Claude Code agents in parallel (CI, orchestrator setups, dev fleet), each one spawns its own Bun process. 10 agents = 10 runtimes = ~1 GB just for Telegram bridges. The Solution: hdcd-telegram We built hdcd-telegram -- a Rust drop-in replacement with full feature parity. Bun (official) Rust (hdcd-telegram) Binary size ~100 MB (runtime + deps) 3.5 MB RAM per instance ~100 MB ~5 MB 10 parallel agents ~1 GB ~50 MB Startup 2-3 seconds <50 ms Shutdown Ke
