llm-keys-ui 0.1

Simon Willison published release 0.1 of llm-keys-ui, described as an LLM web UI for setting keys. In his post, Willison says the plugin solves a very specific problem: he has started using Codex Remote to run coding agents on various machines while controlling them from his phone. Sometimes he uses those machines to hack on LLM projects, and occasionally that means he needs to configure an API key. He writes that he does not like pasting API keys into agent sessions, so he wanted a way to get those keys onto a machine without pasting them into the ChatGPT app directly. With the plugin, Willison says he can tell Codex to run the command uvx --with llm-keys-ui llm keys-ui --all, then have it tell him the URL, including local network or Tailscale device IPs, for an interface to save additional API keys. Later, he writes, it can use a command like llm keys get anthropic as part of a shell command when it needs to use a key. The post is dated 20th September 2026 and is tagged llm, coding-agents, and codex. No other technical details, supported providers, or security properties are stated in the source text.
