company
JetBrains is a software company making developer tools like IntelliJ IDEA, PyCharm, and WebStorm, and creator of the Kotlin programming language.
No evidence-backed relationships are recorded.
JetBrains opened early access to Air, a plugin and 2026.3 EAP feature that runs a developer's existing coding agents as parallel sessions inside its IDEs. Air needs no JetBrains AI subscription, so a team can trial multi-agent work on the agent plans it already pays for.
Reality
JetBrains' Kotlin 2.5.0-Beta1 adds an off-by-default mode that stops Multiplatform common code from compiling against dependencies' platform-only declarations. With the flag on, builds reject the calls IntelliJ already flags as unresolved, so KMP teams are better off finding that breakage on a branch first.
Reality
Generic methods collapse per-type API sprawl, go fix gains four modernizers, and the goroutineleak profile in runtime/pprof is now generally available. GoLand 2026.2 supports all three.

Two companies selling AI agents to enterprise engineering teams took in at least $2.2 billion of new equity within seven days, each selling about 4 percent of itself, and only one of the two prices has a revenue multiple attached.

CISA said Sept. 23 that ransomware crews are exploiting CVE-2026-63077, an unauthenticated 9.8 RCE in JetBrains TeamCity patched July 25. Any build server patched late has to be handled as breached, including the credentials and signing keys it held.
Reality
Six months after introducing JetBrains Central, JetBrains has renamed it Air Governance and made it the place an organization sees and caps what agents from any vendor cost it. The IDE becomes one surface of several.

A dev.to writeup traces roughly 3,800 exfiltrated GitHub repositories to one trojanised Nx Console install from the official Marketplace, where the sandbox that would have contained it has been an open feature request since 2018.
Reality
JetBrains puts weekly AI coding agent use at 90% of professional developers in mid-2026. A dev.to post argues the sites those agents scaffold collapse onto one section order and one URL, and treats page architecture as work that has to precede generation.
Reality
The typed authentication module and Netty's HTTP/3 support both arrive experimental in Ktor 3.6.0, while the changes that touch code you already wrote are two deprecations and one client Accept-header setting.
Reality
The merged 27B finished 37 of 100 internal coding tasks against 34 for the fast checkpoint and 39 for the reasoning one, and it did that while emitting 71% fewer output tokens than the 39, with no post-training in the recipe.
Reality
The new Junie CLI mode needs Docker, a generated build plan and a request specific enough to check, and the report it returns marks each check passed, failed or incomplete. JetBrains says it has run the agent on more than 1,500 of its own pull requests.
Reality
Cline's coding agent runs on one engine in four places, licensed Apache 2.0, with a CLI built to run headless inside pipelines and a Node SDK for teams that want to build their own agent on top of it.
Reality
JetBrains' walkthrough finds a discount bug in a containerised gRPC server by attaching a debugger on port 5005 and editing log expressions between requests. Those expressions run inside the server's VM.
Reality
The OpenTelemetry plugin classifies spans off their attributes and folds each one into an architecture model on arrival. A trace never signals that it is complete, so the algorithm never waits for one.
Reality
JEP 527's hybrid key exchange landed as a stable feature on September 15, and the same JDK makes G1 the collector on small machines and cuts every object header to 64 bits. Serial is still one flag away.

The Kotlin Benchmark grades agents on 105 verified repository tasks. Its token column shows setups that solve within a few tasks of each other burning between 66,000 and 777,000 tokens per fix.
Reality
Coding-agent failures cluster in the plumbing between knowing what to change and changing it. One harness builder measured what that costs and published the failure rates for Grok 4 and GLM-4.7.
Reality
A Kotlin blog post explores adding a JVM target to Compose HTML so backends emit type-safe components instead of strings. It is framed as an exploration, not a commitment.
Reality
Admins can now set filesystem, network, proxy, developer-tool and Keychain limits for Copilot sessions from inside the plugin rather than through a device-management request, and a new diagnostics tool tells them whether the policy reached the laptop.
Reality
A refactor that moved no logic changed how Microsoft Defender treats the binary, because the trust rules follow the install path. JetBrains published the ETW harness, so the cost is measurable on your own machines.
