## Why Explyt?

A free way to get Spring-focused tooling in IDEA Community. Explyt is **not** a full IDEA Ultimate replacement — it is strongest when runtime bean accuracy, Kotlin Spring support, HTTP testing, and AI-agent/MCP workflows matter.

Legend: ✅ first-class · ◐ partial / setup-dependent · ❌ not available

| Capability | **Explyt (CE)** | IDEA Ultimate | VS Code + STS4 | IDEA CE alone |
|---|:---:|:---:|:---:|:---:|
| **Native context mode** — real bean metadata via javaagent (conditional/factory/library beans) | ✅ | ◐ static model; runtime via Actuator | ◐ needs running app + Actuator | ❌ |
| **Spring Debugger** — context tree, transactions, runtime property resolution | ✅ | ◐ | ◐ | ❌ |
| **Swagger UI HTTP client + `.http`/`.rest` runners** in CE | ✅ | ◐ | ◐ via extensions | ❌ |
| **Spring-aware MCP tools** for AI agents (7 tools, 2025.2+) | ✅ | ❌ | ❌ | ❌ |
| **Kotlin-first Spring inspections** — `internal`/`object` beans, `coRouter` | ✅ | ◐ | ◐ | ❌ |

## Features

> Highlights below. For the complete feature list — Spring Data, AOP, Docker/K8s, inlay hints, code generation, SPI beans, Kotlin inspections, and more — see the [**Features wiki**](https://github.com/explyt/spring-plugin/wiki/Features).

### 🧠 Native context mode — the differentiator

Instead of analyzing source only, Explyt runs a **lightweight version of your app** and uses a javaagent + declarative bytecode patching to extract **real** bean metadata at Spring startup. That gives accurate detection of `@Conditional`, profile, factory, library, and multi-context beans.

→ [How Native Context Mode works](https://github.com/explyt/spring-plugin/wiki/Native-Context-Mode)

### 🐞 Spring Debugger

A dedicated debug mode shows the **Spring Context** and **Active Transaction** in the debugger tree, resolves **runtime property values** as Code Vision in `.properties` / `.yml`, and lets you evaluate bean methods at breakpoints.

### 🌐 Built-in HTTP client: Swagger UI + `.http` / `.rest`

Generate OpenAPI from Spring Web methods and open **Swagger UI inside the IDE**; execute, inspect, and copy cURL. Or run `.http` / `.rest` files via **JetBrains HttpClient CLI** or **httpyac**.

→ [HTTP client guide](https://github.com/explyt/spring-plugin/wiki/HTTP-Client)

### 🧭 Endpoints & beans navigation

The **Explyt Endpoints** tool window lists MVC/WebFlux endpoints, router functions, and message broker listeners (Kafka/RabbitMQ). Jump to any bean via the **Beans** tab in Search Everywhere (`Shift Shift`) and explore dependencies with **Bean Analyzer**.

### 🤖 Kotlin-first & AI-agent ready

Kotlin-specific Spring inspections catch an `internal` `@Bean` whose JVM name is mangled and an `object` declared as `@Component`, with quick-fixes. Kotlin `coRouter` endpoints are supported. For agentic clients, Explyt ships **7 Spring-aware MCP tools** on the bundled JetBrains MCP Server (IDEA 2025.2+).

→ [MCP tools](https://github.com/explyt/spring-plugin/wiki/MCP-Tools)

**Also included:** Quarkus CDI/JAX-RS/AOP, Spring Initializr, Docker Compose/K8s property completion, `@Profile` / `@Scheduled` inlay hints, code generation, and many inspections & quick fixes.

---

## Tool Windows

- **Explyt Spring** — load real bean metadata, browse contexts, view aspects, open **Bean Analyzer**. Entry point for native context mode: **Link … From RunConfiguration** → **Load Beans**.
- **Explyt Endpoints** — Web + message-broker endpoints in one navigable view.

▶ [Native Context Mode](https://github.com/user-attachments/assets/db380852-d239-4e0f-a1b2-15a3a2659f53) · [Endpoints](https://github.com/user-attachments/assets/e38625a3-bc68-4075-9efa-945e64977f36)

## Usage

1. **Load beans:** open **Explyt Spring**, link your run configuration, click **Load Beans**.
2. **Explore endpoints:** open **Explyt Endpoints**; navigate Web + broker handlers.
3. **Test APIs:** add Spring Web annotations and click the **Run** gutter icon → Swagger UI; or run `.http` / `.rest` files.
4. **Fix issues:** `Alt+Enter` on highlights for Spring-aware quick fixes.
5. **Generate:** `Alt+Ins` → Spring Web Method / HttpClient Method / JPA `equals`/`hashCode` / Properties↔YAML.
