https://joymux.com/blog/ What JoyMux guarantees — durable execution state for coding agents. New notes as the product ships. https://joymux.com/blog/why-joymux-is-different/ https://joymux.com/blog/why-joymux-is-different/ Thu, 27 Aug 2026 03:57:14 GMT Research on existing products — tmux, native CLI resume, cloud sandboxes — and why chat history is still a bad database for your computer. https://joymux.com/blog/trial-lease-and-monthly/ https://joymux.com/blog/trial-lease-and-monthly/ Mon, 24 Aug 2026 13:00:00 GMT 14 days free, $0 due today. A signed lease on your machine. Then $29/month through hosted checkout — card details never touch joymux.com. https://joymux.com/blog/how-evidence-works/ https://joymux.com/blog/how-evidence-works/ Mon, 24 Aug 2026 12:00:00 GMT Keep the complete execution record locally. Send the model only the delta. Replay is reading the record — not reconstructing it from chat. https://joymux.com/blog/sessions-that-survive/ https://joymux.com/blog/sessions-that-survive/ Mon, 24 Aug 2026 11:00:00 GMT Detach does not kill the work. Attach reconnects you. Close ends the session. User-visible lifecycle — not an internals dump. https://joymux.com/blog/how-joymux-works/ https://joymux.com/blog/how-joymux-works/ Mon, 24 Aug 2026 10:00:00 GMT Your AI shouldn't have to remember your computer. The public contract — interrupt, resume, hand off, shrink context, verify — and how you test it. https://joymux.com/blog/training-my-own-ai/ https://joymux.com/blog/training-my-own-ai/ Mon, 24 Aug 2026 00:00:00 GMT A founder use case — GPU training jobs plus multi-agent coding on the same box. JoyMux kept execution state durable and context bounded so the machine stayed usable. https://joymux.com/blog/handoff-rediscovery/ https://joymux.com/blog/handoff-rediscovery/ Sun, 23 Aug 2026 00:00:00 GMT The unfinished checkout API Agent A handed off. On that snapshot, rediscovery calls went 15 → 1, files reread 8 → 0, context tokens 2409 → 271. Tests still passed. Not a speed claim. https://joymux.com/blog/one-layer-many-harnesses/ https://joymux.com/blog/one-layer-many-harnesses/ Sat, 22 Aug 2026 00:00:00 GMT Your harness will change. Execution state should not. Codex, Claude Code, Gemini, and OpenCode over the same local execution record. https://joymux.com/blog/replay-missed-output/ https://joymux.com/blog/replay-missed-output/ Sat, 22 Aug 2026 00:00:00 GMT Scrollback is not a record. Replay from durable execution evidence when you were looking at the other pane. https://joymux.com/blog/send-the-delta/ https://joymux.com/blog/send-the-delta/ Sat, 22 Aug 2026 00:00:00 GMT Dumping full scrollback into the next prompt wastes tokens and blurs the work. Bounded context views send what changed. https://joymux.com/blog/when-the-terminal-dies/ https://joymux.com/blog/when-the-terminal-dies/ Sat, 22 Aug 2026 00:00:00 GMT Terminals are disposable. Execution shouldn’t be. How persistent sessions let coding agents resume after a crash. https://joymux.com/blog/why-terminals-are-a-bad-runtime/ https://joymux.com/blog/why-terminals-are-a-bad-runtime/ Sat, 22 Aug 2026 00:00:00 GMT A terminal is a window, not a runtime. Why multi-agent work thrashes the machine when execution lives in tabs. https://joymux.com/blog/hard-reset-same-state/ https://joymux.com/blog/hard-reset-same-state/ Thu, 06 Aug 2026 00:00:00 GMT A crash should not mean starting over — or paying the tokens again. Recover to the same execution state. https://joymux.com/blog/token-ten-x-honest/ https://joymux.com/blog/token-ten-x-honest/ Wed, 05 Aug 2026 00:00:00 GMT Token savings are a consequence of persistent execution and bounded context — not the headline. Founder testing saw about 10×, with clear metering labels. https://joymux.com/blog/why-joymux-exists/ https://joymux.com/blog/why-joymux-exists/ Sat, 01 Aug 2026 00:00:00 GMT Most tools focus on the agent. Almost nobody focuses on execution state underneath — what survives when the terminal dies.
