All your agents are going async

Article

TL;DR

Agents that outlive HTTP sessions need durable state and reconnectable transports — not just SSE.

Key Takeaways

• HTTP request-response breaks when agents run for hours or across device switches
• Working solutions today: tmux+SSH ($5/mo server), Cloudflare Durable Objects, Google ADK
• Post is partly a pitch for Ably; competing infra (Durable Objects) is strawmanned

• [bozdemir]: Disclosure buried at the end; transport isn’t the real problem — interaction model is
• [TacticalCoder]: Simplest durable async agent solution is SSH + tmux on a $5/mo server

  $5 per month dedicated server, SSH, tmux.

• [pdp]: Injecting messages into another agent’s context mid-run doesn’t work well in practice
• [tuo-lei]: Session state non-portability between tools (Claude Code JSONL vs Cursor SQLite) is the real blocker
