BootUI

BootUI adds an embedded, local-only developer console to your application. It runs on Spring Boot (servlet or WebFlux) and Quarkus, serving the same Vue UI and REST contract (/bootui and /bootui/api/** by default, configurable with bootui.path / bootui.api-path) from a shared, framework-neutral engine — add the Spring Boot starter (one for both stacks) or the Quarkus extension and BootUI activates only in local development.

BootUI 2.0 is available on Maven Central, with exact correlation, a runtime journal, Runtime Insights, run comparison, and optional Java-agent instrumentation. Follow the setup guide, read its known limitations, and share feedback in GitHub Discussions.

Use with AI agents

BootUI exposes a local, opt-in Model Context Protocol server so AI coding agents (GitHub Copilot, Claude Code, …) can run its advisors and read runtime diagnostics while fixing your code.

Install the BootUI skill in any Agent Skills-compatible coding agent:

npx skills add https://github.com/jdubois/boot-ui/tree/main/skills/bootui

The interactive installer detects supported agents and installs the canonical consumer skill. Native integrations are also available:

Agent	Native installation
GitHub Copilot	gh skill install jdubois/boot-ui skills/bootui
Claude Code	/plugin marketplace add jdubois/boot-ui, then /plugin install bootui@bootui
Cursor	Find BootUI on Cursor Directory

The Cursor and Claude Code plugins install the skill and configure the MCP server together. BootUI also pairs with Coffilot, a GitHub Copilot canvas extension that builds, runs, and scans your app from the GitHub Copilot App's side panel. See the AI agents guide for preview, configuration, and safety details.

Use from a terminal

The bootui CLI asks a running application one question and prints the answer, with one command per BootUI diagnostic — the same set the MCP server exposes, projected mechanically from the same registry.

curl -fsSL https://www.julien-dubois.com/boot-ui/install.sh | sh

bootui beans --query dataSource
bootui hibernate scan --json | jq '.topFindings[]'

It needs no MCP client and no agent, prints exact JSON when piped, and exits 2 when a panel's own policy declines the call and 3 when --fail-on <severity> finds a finding at or above that severity, or --fail-on insufficient finds insufficient or partial evidence, so CI can branch on it. Windows has a PowerShell installer, and JBang works too — see the command-line guide.

Use in CI

Add the BootUI Action to a job and it automatically starts the conventional Spring Boot or Quarkus development process, runs every available local CI advisor, reports findings in the job summary, and fails on HIGH or CRITICAL findings. An optional workload can exercise that same process before assessment. The application stays on the same runner, bound to loopback; BootUI is not a remote or production scanner. Start with the GitHub Actions quick start.

CI support is not yet published. Published BootUI CLI 2.3.0 does not contain these CI commands. The examples below are prepared for the first signed CI-capable release; UNRELEASED is not an installable version. Do not substitute the old published CLI.
