Profile

Hey HN!I built *Sourcetool* because I wanted Retool-speed without leaving the IDE.What it is:* Write backend functions Sourcetool streams a WebSocket UI to the browser.* No drag-drop builder, so Copilot / Cursor can read & refactor your tool.* Everything is plain code → PR reviews, CI, Git history just work.* Self-hosted binary, no data leaves your infra.30-second taste:```gofunc usersPage(ui sourcetool.UIBuilder) error { name := ui.TextInput("Name") // Just call your existing backend logic here // Example: a function that queries users from your database users, err := listUsers(name) if err != nil { return err } ui.Table(users) return nil }```Try it out: https://github.com/trysourcetool/sou

Within the show hn launch space, the company focuses on its core offering rather than a broad product line.

It is recorded at the Show HN launch stage.
