Line0

About

Line0 narrows the AI coding problem to one domain — Express.js backend services — where a focused harness can produce production-ready results instead of generic scaffolding. Developers describe backend functionality in plain language, use tab-to-prompt for inline generation, and organize work into separate per-feature chats; code syncs both ways with a GitHub repository on a chosen branch so the user's normal workflow continues unchanged. An in-browser editor covers the full project, and a built-in API client with hot reload and auto-provisioned database previews is on the roadmap. Pricing runs from a free tier through Plus ($17/mo) to Pro ($85/mo); it is made by Vratix and aimed at Node.js API developers.
