Rex supports programmable workspaces, session continuity across devices, and runtime observability for agent activity. It also links a whiteboard session explaining why database timestamps can be misleading, since a transaction's timestamp can stay fixed while wall-clock time advances and creation order doesn't always match commit order. Other links include a JavaScript HTML parser that is 3 to 6 times faster than other JavaScript parsers, and Cartesia's h-nets research, which uses bytes instead of tokens and 10x less compute. ## Full article daily.dev links to this article rather than hosting it. Read it at the original source: ## Questions this post answers ### What is Rex and how does it work with AI coding agents? Rex is a terminal multiplexer, similar to tmux, with a client/server system and its own terminal app powered by libghostty. It connects terminals via sessions so AI agents and scripts can launch programs, read output, and send input to specific terminals, for example letting codex send prompts to and approve commands in claude and vice versa. It also supports session continuity across devices and runtime observability of agent activity. _developers wiring up multi-agent terminal workflows can track new multiplexer tools like this on daily.dev._ ### Why can database timestamps be misleading for ordering records? A transaction's timestamp can stay fixed even as wall-clock time moves forward, and a transaction that starts first can finish last, so creation timestamps don't always reflect commit order. This means a worker advancing a cursor by creation time can skip writes that commit later, silently dropping records from queues or processing pipelines. _engineers debugging queue or worker skip bugs can dig into timestamp pitfalls like these on daily.dev._ ## Community discussion Top comments from developers on daily.dev. **@drakeboley** · 0 upvotes > im definitely multiplex-maxxing ## Similar posts on daily.dev - [coder/mux: A desktop app for isolated, parallel agentic development](https://daily.dev/posts/coder-mux-a-desktop-app-for-isolated-parallel-agentic-development-xwzfjgmu6) · Hacker News · 8 upvotes · 0 comments - [Looking Beyond Tmux and Screen: 8 Terminal Multiplexers Worth Trying](https://daily.dev/posts/looking-beyond-tmux-and-screen-8-terminal-multiplexers-worth-trying-3v9aibk3d) · It's Foss · 0 upvotes · 0 comments --- Tags: [#javascript](https://daily.dev/tags/javascript), [#ai-agents](https://daily.dev/tags/ai-agents), [#bash](https://daily.dev/tags/bash) [View this post on daily.dev](https://daily.dev/posts/the-masculine-urge-to-multiplex-everything-cne0wucth) ```json {"@context":"https://schema.org","@graph":[{"@type":"Organization","@id":"https://daily.dev/#organization","name":"daily.dev","url":"https://daily.dev","logo":{"@type":"ImageObject","url":"https://daily.dev/apple-touch-icon.png","width":180,"height":180},"sameAs":["https://twitter.com/dailydotdev","https://github.com/dailydotdev","https://www.linkedin.com/company/daily-dev-ltd"]},{"@type":"WebSite","@id":"https://daily.dev/#website","url":"https://daily.dev","name":"daily.dev","publisher":{"@id":"https://daily.dev/#organization"},"potentialAction":{"@type":"SearchAction","target":{"@type":"EntryPoint","urlTemplate":"https://daily.dev/search?q={search_term_string}"},"query-input":"required name=search_term_string"}}]} {"@context":"https://schema.org","@type":"TechArticle","headline":"The masculine urge to multiplex everything","url":"https://daily.dev/posts/the-masculine-urge-to-multiplex-everything-cne0wucth","mainEntityOfPage":{"@type":"WebPage","@id":"https://daily.dev/posts/the-masculine-urge-to-multiplex-everything-cne0wucth"},"datePublished":"2026-10-30T19:58:49.067Z","dateModified":"2026-10-30T19:59:17.055Z","description":"This newsletter issue covers Rex, a terminal multiplexer in public beta that works like tmux but lets AI agents send input and read output across multiple...","image":"https://media.daily.dev/image/upload/f_auto,q_auto/v1/posts/01affdafa6f2af0f0220829d891d657d?_a=AQAEuop","thumbnailUrl":"https://media.daily.dev/image/upload/f_auto,q_auto/v1/posts/01affdafa6f2af0f0220829d891d657d?_a=AQAEuop","isAccessibleForFree":true,"articleSection":"Bytes by ui.dev","inLanguage":"en","publisher":{"@type":"Organization","name":"daily.dev","url":"https://daily.dev","logo":{"@type":"ImageObject","url":"https://daily.dev/apple-touch-icon.png","width":180,"height":180}},"author":{"@type":"Organization","name":"Bytes by ui.dev","logo":"https://media.daily.dev/image/upload/s--wMrI6PMo--/f_auto/v1718347131/logos/bytesdev","url":"https://daily.dev/sources/bytesdev"},"commentCount":1,"discussionUrl":"https://daily.dev/posts/the-masculine-urge-to-multiplex-everything-cne0wucth","interactionStatistic":[{"@type":"InteractionCounter","interactionType":{"@type":"LikeAction"},"userInteractionCount":0},{"@type":"InteractionCounter","interactionType":{"@type":"CommentAction"},"userInteractionCount":1}],"keywords":"javascript,ai-agents,bash","timeRequired":"PT5M"} {"@context":"https://schema.org","@type":"BreadcrumbList","itemListElement":[{"@type":"ListItem","position":1,"name":"Home","item":"https://daily.dev"},{"@type":"ListItem","position":2,"name":"Bytes by ui.dev","item":"https://daily.dev/sources/bytesdev"},{"@type":"ListItem","position":3,"name":"The masculine urge to multiplex everything"}]} {"@context":"https://schema.org","@type":"WebPage","@id":"https://daily.dev/posts/the-masculine-urge-to-multiplex-everything-cne0wucth","comment":[{"@type":"Comment","text":"im definitely multiplex-maxxing","datePublished":"2026-10-31T02:11:06.170Z","url":"https://daily.dev/posts/CNE0wuctH#c-r72KZnnrp","author":{"@type":"Person","name":"Drake Boley","url":"https://daily.dev/drakeboley","image":"https://lh3.googleusercontent.com/a/ACg8ocInDqBr3mIGG861l52WRmtmkcZZ2bf7p1G-l4ljGfAyeU_Wwg=s96-c"}}]} {"@context":"https://schema.org","@type":"FAQPage","@id":"https://daily.dev/posts/the-masculine-urge-to-multiplex-everything-cne0wucth#faq","mainEntity":[{"@type":"Question","name":"What is Rex and how does it work with AI coding agents?","acceptedAnswer":{"@type":"Answer","text":"Rex is a terminal multiplexer, similar to tmux, with a client/server system and its own terminal app powered by libghostty.
