# JetBrains JetBrains is a Czech software company founded in 2000, best known for [[IntelliJ IDEA]] and a broad family of language-specific IDEs built on the IntelliJ Platform. The company's products are widely used by professional developers across the JVM, Python, web, mobile, and systems-programming ecosystems. ## What JetBrains is known for - **IntelliJ Platform** — the shared technology foundation behind every JetBrains IDE - **Language-specific IDEs** — IntelliJ IDEA (Java/Kotlin/JVM), PyCharm (Python), WebStorm (web), GoLand (Go), RubyMine, PhpStorm, DataGrip (databases), CLion (C/C++), Rider (.NET) - **Kotlin** — programming language created by JetBrains in 2011, later adopted as a first-class Android language by Google in 2017 - **JetBrains Toolbox** — central installer and updater for all JetBrains IDEs - **JetBrains AI Assistant** — paid AI features integrated across the IDE family (chat, completion, refactoring suggestions) - **[[Junie (JetBrains)|Junie]]** — JetBrains' coding agent, embedded in their IDEs - **[[Mellum]] / [[Mellum2]]** — JetBrains' open-weight models (Mellum for code completion; Mellum2 a 12B MoE for natural language + code) - **[[Agent Client Protocol (ACP)]]** — open protocol initiated by JetBrains to standardize editor ↔ AI agent communication, analogous to LSP - **[[JetBrains Air]]** — JetBrains' agentic development environment ([[Agentic Development Environment (ADE)|ADE]]), public preview March 2026 - **TeamCity, YouTrack, Space** — CI, issue tracking, and team collaboration products ## Strategic posture in the AI era JetBrains' bet is two-pronged. First, keep the IDE relevant by embedding agents directly (AI Assistant, Junie) and standardizing the integration layer (ACP). Second, hedge against the IDE itself becoming obsolete by shipping a separate ADE ([[JetBrains Air]]) that orchestrates external agents (Codex, Claude Agent, Gemini CLI, Junie) without forcing users out of their existing IDE workflow. The split product line says: *we don't yet know whether the IDE or the ADE wins, so we're building both*. ## References - Homepage: https://www.jetbrains.com - Products page: https://www.jetbrains.com/products/ - ACP: https://www.jetbrains.com/acp - Air: https://air.dev/ ## Related - [[Junie (JetBrains)]] - [[Mellum]] - [[Mellum2]] - [[IntelliJ IDEA]] - [[JetBrains Air]] - [[Agent Client Protocol (ACP)]] - [[Agentic Development Environment (ADE)]] - [[Idea Development Environment (IDE)]] - [[Cursor.com]] - [[Visual Studio Code (VSCode)]] - [[Claude Code IDE Integration]]
