{"slug": "web-edit-0-1a0", "title": "web-edit 0.1a0", "summary": "Simon Willison released web-edit 0.1a0, a Python web app that provides a browser UI for viewing and editing files in a folder, built by Codex and GPT-6 Astra Extra High. Willison created the tool while working from his phone via Codex Remote, aiming to edit a credentials file without passing those credentials through the LLM, and intends it to run over Tailscale so an agent can start it and he can edit files directly from his phone. The editor uses CodeMirror 6 rather than Monaco because Monaco lacks a good mobile experience.", "body_md": "**Release:** [web-edit 0.1a0](https://github.com/simonw/web-edit/releases/tag/0.1a0)\n\nI was working on a project from my phone using Codex Remote when I found myself wanting to edit a credentials file without round-tripping those credentials through the LLM itself.\n\nSo... I had Codex and GPT-6 Astra Extra High build this Python web app which provides a web UI for viewing and editing files in a folder. It's intended to be run over Tailscale, so I can have an agent start this running and then edit files via my Tailscale network directly from my phone.\n\nHere's the interface for browsing files in a folder:\n\nEditing uses [CodeMirror 6](https://codemirror.net) - I was going to use [Monaco](https://microsoft.github.io/monaco-editor/) but that still doesn't have a great mobile experience yet.\n\nTags: [projects](https://simonwillison.net/tags/projects), [python](https://simonwillison.net/tags/python), [ai](https://simonwillison.net/tags/ai), [tailscale](https://simonwillison.net/tags/tailscale), [generative-ai](https://simonwillison.net/tags/generative-ai), [llms](https://simonwillison.net/tags/llms), [codex](https://simonwillison.net/tags/codex)", "url": "https://wpnews.pro/news/web-edit-0-1a0", "canonical_source": "https://simonwillison.net/2026/Oct/12/web-edit/", "published_at": "2026-10-12 15:54:36+00:00", "updated_at": "2026-10-15 05:17:55.901916+00:00", "lang": "en", "topics": ["ai-agents", "developer-tools", "ai-tools", "generative-ai"], "entities": ["Simon Willison", "web-edit 0.1a0", "Codex Remote", "GPT-6 Astra Extra High", "CodeMirror 6", "Monaco", "Tailscale", "Python"], "also_reported_by": [], "alternates": {"html": "https://wpnews.pro/news/web-edit-0-1a0", "markdown": "https://wpnews.pro/news/web-edit-0-1a0.md", "text": "https://wpnews.pro/news/web-edit-0-1a0.txt", "jsonld": "https://wpnews.pro/news/web-edit-0-1a0.jsonld"}}
