Xiao Lan

Xiao Lan is a niche British micro-publisher that concentrates on friction-free tooling for developers who juggle several cloud-based AI pair-programming identities. Its single-title catalogue, Codex Account Switch, is a lightweight Windows tray utility that lets users hot-swap API keys, endpoints and tenant settings for OpenAI, GitHub Copilot, Codeium, Tabnine and similar services without restarting VS Code, JetBrains IDEs or the browsers embedded in modern editors. Typical use cases include consultants who move between client organisations, open-source contributors who keep personal and corporate subscriptions separate, and teams that need to toggle from a shared paid tier back to an individual trial key when monthly quotas run low. The program stores credentials in an encrypted local vault, refreshes environment variables in real time, and can optionally launch the correct profile-specific workspace so that context, history and suggestions stay compartmentalised. By eliminating manual file edits or shell scripts, it fits into automation pipelines and CI agents just as comfortably as it sits on a laptop. Although the portfolio is currently a one-product line, the publisher maintains an active GitHub issue tracker where feature requests for additional IDEs and cloud hosts are voted on by an expanding user base. Xiao Lan’s software is available for free on get.nero.com, with downloads delivered through trusted Windows package sources such as winget, always installing the latest release and supporting batch installation alongside other applications.
