Open-source mydash lets users view Claude Code and Codex outputs on mobile

On 2026-10-30, a developer posted on V2EX about the open-source, self-hosted tool mydash, built to view the outputs of coding agents like Claude Code and Codex on a computer or a phone. These agents produce a steady stream of artifacts the user actually has to read: proposals, research reports, comparison tables, screenshots, web prototypes, and occasionally Word documents. Previously they were nothing more than file paths in a terminal, awkward to read even on a desktop and effectively impossible on a phone, according to the author. mydash is a small service written in Node without any framework, running on the user's own machine.

When an agent runs mydash publish, the user receives a link leading to the formatted output. The service renders Markdown with Mermaid diagrams, displays PDFs page by page, runs web prototypes on a separate port, previews Excel and CSV tables, and offers typeset previews of Word and PowerPoint documents. Artifacts are grouped by project, understood as the folder the session started in, with version comparison and unread markers. The author uses Tailscale to browse the same links from a phone.

A few capabilities were added after the initial release. Users can select a passage in the web interface and leave an annotation; an agent then reads it with mydash feedback and marks it handled once it has made changes. When several decisions are pending at once, the agent can send a single approval form instead of firing a long series of questions in its reply. Claude Code's multiple-choice prompts, plan confirmations, and permission requests appear in both the terminal and mydash, and whichever side answers first takes effect. If no one responds within 30 seconds, the request is pushed to the phone through channels such as Bark and ntfy.

mydash is released as open-source software that users host themselves, and all the features described here come from the author's own post; no independent coverage has appeared yet.
