BootUI

BootUI provides a local-only developer console designed specifically for Spring Boot 4 and Quarkus applications. It addresses the need for runtime observability, diagnostics, and security analysis during development, offering a centralized interface to monitor and analyze various aspects of a running Java application without exposing sensitive data beyond the local environment. The tool enables inspection of health, metrics, memory usage, threads, heap dumps, startup timing, and JVM sizing directly from the host application. Developers can also access an advisors dashboard that analyzes and scores the application using advanced advisors covering architecture, REST APIs, Spring, Hibernate, JVM memory, Spring Security, pentesting, and vulnerability assessment. The diagnostics toolbox includes features for reviewing traces, log tails, HTTP exchanges, local probes, architecture checks, GraalVM readiness, and dependency vulnerabilities. BootUI also provides visibility into data and services by allowing exploration of database pools, Spring Data repositories, Hibernate checks, Flyway, Liquibase, scheduled tasks, caches, and development services. Configuration tools are available for managing masked properties, profile differences, runtime overrides, loggers, beans, conditions, and mappings. The platform includes developer dashboards for tools such as DevTools, GitHub, Copilot, and Claude Code local activity. The console is delivered as a packaged dependency—a Spring Boot starter or Quarkus extension—so developers can add it to their applications without a separate frontend deployment. BootUI serves its Vue-based user interface and REST API directly from the host application at a dedicated endpoint, and does not require Node.js or npm. It operates in a loopback-only mode by default, enforcing a local safety model with secret masking, fail-closed activation, read-only controls, and explicit confirmation for any mutating actions. Some panels depend on optional Spring, Actuator, or development infrastructure, and the tool is designed to handle unavailable data gracefully with stable empty responses.
