Cloudflare Gateway and Data Loss Prevention have inherited the flexibility and power of Cloudflare Workers through our full-stack integration with the Cloudflare Developer platform.

Google Summer of Code 2026 has wrapped up! This was the Kotlin Foundation’s fourth year participating in GSoC, bringing new contributors into the Kotlin open-source ecosystem through hands-on projects and mentorship. This year, two projects successfully reached completion, tackling two areas of the ecosystem: improving recursion support in the Kotlin/Wasm backend and building a global […]

Introducing Void: an open-source SDK, CLI, and self-hosted platform for building full-stack Vite apps and deploying them to Cloudflare.

Ten weeks ago, we opened up a preview of an LSP-powered extension that brings IntelliJ IDEA’s smartness for Java and Kotlin into VS Code and Cursor. As mentioned in that blog post, this is part of a bigger initiative: moving our JVM intelligence to wherever our users are, no matter what editor or agent they […]

How Cloudflare and OpenAI are working together to help AI find useful content, keep up with changes, and make fewer wasted requests — making the experience better for users and website owners alike.

Netflix plugged JetBrains’ headless code-intelligence engine – the same one behind IntelliJ IDEA – into Claude Code and Codex, then benchmarked it against a variety of scenarios. The details and numbers are available below. At a glance Company Netflix – Application Development Platform (ADP), GenAI Platform, and Agentic SDLC teams Challenge Coding agents were struggling […]

When strikes hit Yandex data centers, many assumed Russian bot operations went dark. Cloudflare data reveals that while search crawling stopped, malicious bots simply migrated to other networks.

In September, we experienced two incidents that resulted in degraded performance across GitHub services. The post GitHub availability report: September 2026 appeared first on The GitHub Blog.

Our new repo star history API now provides trends without returning individual identities or requiring unbounded database work. These are the engineering tradeoffs we made. The post From 2,500 requests to 24: Rebuilding star history without the stargazers appeared first on The GitHub Blog.

While adding MySQL support to Hyperdrive, we found a subtle protocol bug when caching query results. Here is how we tracked down a 0.001% rate error and made Hyperdrive MySQL generally available.

Your CI/CD pipeline builds fast, but does it build right? While your automated builds and deployments handle the mechanics of software delivery, catching code quality issues often falls to manual reviews, which, while hugely valuable, can sometimes miss more subtle problems. That’s where Qodana changes the game by bringing the power of IntelliJ IDEA’s inspection […]

Recently, we released a preview of cloud agents in JetBrains Air. Cloud agents let you run AI agents remotely in a JetBrains-managed cloud environment, giving them an isolated place to work without relying on your local machine. Here’s what that looks like in practice. In this video, I start a task in IntelliJ IDEA, follow […]

Yuri Geronimus’s four-year-old son once asked him what his job was. Yuri told him he writes books: books that describe what he wants to change in the physical world. His son didn’t fully get it.  Neither would most engineers: if you understand the words in your application code, you build good systems. If you don’t, […]

You submit a Kubernetes Job and wait for its Pods to appear. A minute passes. Then another. The Job is still suspended, there are no application logs, and there may not even be a Pod to inspect. In a cluster managed by Kueue, this can be completely normal. Kueue may still be deciding whether the Job can use the requested resources. The useful question is not only “Why is the Pod pending?” It is first “Has Kueue admitted the Workload?” The Kueue plugin for Headlamp brings that investigation into

Hoehenkirchen, Germany/Amsterdam, Netherlands — October 14, 2026 — Lauterbach and JetBrains have integrated TRACE32® debugging tools with CLion, JetBrains’ professional C and C++ tool. The integration enables embedded developers to debug applications on target hardware directly from CLion, bringing code editing, navigation, and hardware debugging into one development workflow. Using the Debug Adapter Protocol (DAP), […]

The night before AGNTCon + MCPCon Europe, we hosted the Agentic AI Foundation community at the JetBrains office in Amsterdam. The event filled up fast and went to a waitlist, which is not what I expected for a Wednesday evening discussion about how open foundations work. Ibrahim Malik opening the evening. The panel asked what […]

GitHub’s context-aware secret classifier improves detection quality, raises weighted acceptance by 11.5%, and reduces median scan execution time by 86%. The post GitHub’s model for secret detection: Finding more secrets with less noise appeared first on The GitHub Blog.

A deep dive into how D1 architected its control plane to scale and manage millions of databases, while keeping data plane query operations at the edge. We share guiding principles on how to build on the Developer Platform effectively.
