<p><strong><a href="https://developers.openai.com/codex/cloud/">Codex cloud is now called Codex web</a></strong></p> It looks like OpenAI's <strong>Codex cloud</strong> (the cloud version of their Codex coding agent) was quietly rebranded to <strong>Codex web</strong> at some point in the last few days.</p> <p>Here's a screenshot of the Internet Archive copy from <a href="https://web.archive.org/web/20251218043013/https://developers.openai.com/codex/cloud/">18th December</a> (the <a href="https://web.archive.org/web/20251228124455/https://developers.openai.com/codex/cloud/">capture on the 28th</a> maintains that Codex cloud title but did not fully load CSS for me):</p> <p><img alt="Screenshot of the Codex cloud documentation page" src="https://static.simonwillison.net/static/2025/codex-cloud.jpg" /></p> <p>And here's that same page today with the updated product name:</p> <p><img alt="Same documentation page only now it says Codex web" src="https://static.simonwillison.net/static/2025/codex-web.jpg" /></p> <p>Anthropic's equivalent product has the incredibly clumsy name <a href="https://code.claude.com/docs/en/claude-code-on-the-web">Claude Code on the web</a>, which I shorten to "Claude Code for web" but even then bugs me because I mostly interact with it via Anthropic's native mobile app.</p> <p>I was hoping to see Claude Code for web rebrand to Claude Code Cloud - I did <em>not</em> expect OpenAI to rebrand in the opposite direction!</p> <p><strong>Update</strong>: <a href="https://twitter.com/thsottiaux/status/2006421779246624875">Clarification</a> from OpenAI Codex engineering lead Thibault Sottiaux:</p> <blockquote> <p>Just aligning the documentation with how folks refer to it. I personally differentiate between cloud tasks and codex web. With cloud tasks running on our hosted runtime (includes code review, github, slack, linear, ...) and codex web being the web app.</p> </blockquote> <p>I asked what they called Codex in the iPhone app and <a href="https://twitter.com/thsottiaux/status/2006423057179750625">he said</a>:</p> <blockquote> <p>Codex iOS</p> </blockquote> <p>Tags: <a href="https://simonwillison.net/tags/naming-things">naming-things</a>, <a href="https://simonwillison.net/tags/ai">ai</a>, <a href="https://simonwillison.net/tags/openai">openai</a>, <a href="https://simonwillison.net/tags/generative-ai">generative-ai</a>, <a href="https://simonwillison.net/tags/llms">llms</a>, <a href="https://simonwillison.net/tags/anthropic">anthropic</a>, <a href="https://simonwillison.net/tags/coding-agents">coding-agents</a>, <a href="https://simonwillison.net/tags/async-coding-agents">async-coding-agents</a></p>

<p><strong><a href="http://semver.org/">Semantic Versioning</a></strong></p> Tom Preston-Werner provides a name, specification and URL describing the relatively widely used Major.Minor.Patch versioning system. This is really useful—by giving something a name and a spec, people can say “this project uses semantic versioning” and skip having to explain their backwards compatibility policy in full. <p>Tags: <a href="https://simonwillison.net/tags/naming-things">naming-things</a>, <a href="https://simonwillison.net/tags/open-source">open-source</a>, <a href="https://simonwillison.net/tags/semantic-versioning">semantic-versioning</a>, <a href="https://simonwillison.net/tags/software">software</a>, <a href="https://simonwillison.net/tags/tom-preston-werner">tom-preston-werner</a>, <a href="https://simonwillison.net/tags/versioning">versioning</a></p>
