Show HN: TeamOnly, free hosting for AI-built apps behind your company login

TeamOnly is a hosting service for internal tools built with AI coding tools such as Claude Code or Cursor, deployed with the command `npx teamonly deploy` to a private link like https://expenses.acme.teamonly.app that only coworkers on the company's email domain can open. It includes a database, file storage and secrets set up on first deploy, and sign-in via work Google or Microsoft accounts or a code sent to a work email, checked before app code runs. It offers a 14-day free trial with no card, then from $19 a month.
