BootUI: Embedded Developer UI for Spring Boot and Quarkus with MCP Support

Repositoryjdubois/boot-uiTool

BootUI is an embedded, local-only developer console for Spring Boot 4 and Quarkus. Alongside a Vue-based web interface, the open-source project features a CLI and a local Model Context Protocol (MCP) server that lets AI coding agents inspect runtime diagnostics during development.

Key points

  1. Embedded console: Activates strictly during local development across Spring Boot 4 (Servlet and WebFlux) and Quarkus.
  2. Shared engine: Uses a framework-neutral core serving a Vue UI and REST API (/bootui and /bootui/api/** by default).
  3. MCP server: Offers an opt-in Model Context Protocol server allowing AI assistants such as Claude Code and GitHub Copilot to query runtime diagnostics and advisors.
  4. CLI diagnostics: Includes a terminal tool to inspect runtime properties, Spring beans, or Hibernate scans directly.
  5. Target audience and maturity: Built for Java enterprise developers; currently an emerging open-source project with nearly 300 GitHub stars.

Why it matters

Java developers often lack a standardized, rich local developer console across major frameworks. BootUI provides runtime visibility out of the box and seamlessly feeds this context to modern AI coding assistants.

Analysis

BootUI targets two gaps: the absence of a shared, out-of-the-box local dashboard across modern Java frameworks (Spring Boot and Quarkus) and the lack of runtime diagnostic context for AI agents. Technologically, it is built on Java 17, Spring Boot 4.1.x, Quarkus 3.33 LTS, and Vue.js. In terms of maturity, BootUI is at an emerging stage (around 300 stars), but demonstrates solid engineering practices with active maintenance, CI workflows, CodeQL checks, comprehensive documentation, and direct agent integrations.
