The BasicsUpdated on 25 August 2026we are coded

The company behind the editors millions of programmers work in, and behind the agent Junie. A short entry on who's behind the tools mentioned in the other nodes.

Checked on25 August 2026
In short: JetBrains is a Czech company that makes editors for programmers, IntelliJ IDEA, PyCharm, WebStorm, GoLand, and Rider, and has been standard in large teams for years. Their coding agent is called Junie.

Their tools are a familiar sight to any programmer. Heavy, detailed editors, each one built for its own language: IntelliJ IDEA for Java, PyCharm for Python, WebStorm for JavaScript, GoLand for Go, Rider for C#. Junie is the agent they added on top. It doesn't suggest a line of code, it takes on a task and finishes it.

Through 2026 they've moved in a clear direction. First they put agent abilities across their whole lineup. Then they announced a shared protocol for different agents to talk to each other. Then they shipped a local version of Junie, running right on the machine, with no outside server.

What is code

The computer doesn't think. It reads a recipe and follows it literally, even when the recipe is wrong.

JetBrains1 October 2026Coding agents

JetBrains puts Air into its IDEs: several agents at once, all sessions in one place, on a double Ctrl

Air is an "open system" for agentic development, in early access from 1 October through the 2026.3 EAP builds or as a Marketplace plugin. You run several agents in parallel, locally or in the cloud, each in its own temporary worktree. A JetBrains AI subscription is not mandatory: Junie Lite is free after signing in, and you bring your own Codex, Gemini, GitHub Copilot or Claude Agent.

JetBrains' Junie now runs entirely on your Mac, no cloud, no tokens

JetBrains' code agent now runs locally. No credits, no quota, the code never leaves the machine. The price is the hardware: an M5 chip and at least 64 gigabytes of memory.

JetBrains picked the older Qwen 3.6 over 3.8 because the newer model is slower on a laptop

Behind local Junie sits a string of engineering trade-offs: a quantized model, reasoning turned off, remembered context. The most interesting one is the model choice. The newer Qwen 3.8 was dropped because, with reasoning on, it churns out around five times more tokens.

JetBrains put agents on a shared protocol and called it the LSP moment

ACP separates the editor from the agent: you swap agents without swapping environments and without losing project context. GitHub Copilot works as a protocol server, Claude Code connects through an adapter.

JetBrains puts agentic capabilities across its entire lineup at once

The 2026.2 wave runs through the whole lineup - IntelliJ IDEA, WebStorm, and DataGrip all get Agent Skills, native GitHub Copilot, and MCP tools. The editor stops being a place where you type text and becomes a place where an agent does the work.
