Cortex and Sonar Announce Partnership to Drive Code Quality and Security at Scale

At Cortex, our mission is to empower engineering organizations to ship reliable, secure, and efficient software, faster. Today, we’re thrilled to announce a formalized partnership with Sonar, the leader in code quality and security. For years, Sonar has been one of the most popular integrations in Cortex. Teams rely on Sonar’s deep code insights to identify vulnerabilities, ensure coverage, and raise the bar for clean, secure code.

Introducing Braintrust

How do you balance speed and quality when your customers are counting on you? What does it actually take to build a culture of reliability? And how should engineering leaders think about AI when it's changing everything about how we ship software? On Braintrust, Ganesh Datta, CTO and Co-founder of Cortex, sits down with CTOs, VPs of Engineering, and technical leaders who've been in the trenches—the ones who've made the hard calls, shipped through the chaos, and built teams that actually work.

Black Friday is 30 days away. Your engineering infrastructure might not be ready

If you're anything like your peers, you probably blinked in April and found yourself a month away from Black Friday when you opened your eyes. Much like a shopper desperately scrambling to pull together gift lists for their loved ones, many engineering teams find themselves rushing to ensure their systems can handle the biggest shopping day of the year.

AI Chief of Staff for Engineering Leaders

Meet Cortex’s AI Chief of Staff, your new strategic partner for engineering leadership. This isn’t just another dashboard. It’s an intelligent advisor that connects your engineering data, scorecards, and DORA metrics to give you real-time, actionable insights. What you'll learn in this video: Cortex’s AI Chief of Staff brings clarity and confidence to decision-making, helping leaders transform meetings into strategic, data-driven conversations that drive continuous improvement.

How Cortex brings visibility, governance, and self-service to Kubernetes operations

Platform teams handle cluster provisioning manually because it requires oversight. A product team needs a cluster, so they submit a request. Someone reviews the configuration, provisions it through the cloud provider, waits for it to spin up, and sends back access details. Two days later, the cluster is ready. The delay is intentional. Without review, teams provision oversized clusters that blow budgets, misconfigure networking, or deploy in the wrong regions.

New Feature Friday: Ask Your Engineering Metrics Anything | Cortex Engineering Intelligence for MCP

What if you could analyze your engineering metrics — just by asking a question? Now you can. Introducing Engineering Intelligence for MCP, a new Cortex feature that lets you query your engineering data through AI systems like Claude or Cursor. No dashboards. No BI setup. Just ask: “What’s driving our cycle time?” “Show me Q3 deployment trends.” “Where are our bottlenecks?” Cortex connects your real engineering data to your favorite AI client, so you can get instant, conversational insights on delivery, quality, and team performance — all without leaving your IDE.

A quick recap of IDPCON 2025

Two weeks ago, we hosted IDPCON 2025, and the response has been overwhelming. Over 250 engineering leaders from 20+ countries joined us for 12 sessions featuring speakers from Canva, Skyscanner, Blackstone, and more. Attendees participated in discussions at 20+ roundtables, sharing strategies and challenges around engineering excellence and internal developer portals.

Introducing Braintrust: The exclusive network of engineering leaders shaping the future

In an era of unprecedented change, the role of an engineering leader has never been more demanding. Yesterday’s priority was scaling teams, while today’s is twofold: deploying AI responsibly and measuring the true impact of it all. The challenges are immense, and for the first time in a long time, the playbook is being written in real-time. That’s why today, we are thrilled to announce the launch of Braintrust, a new community from Cortex.

Understand how AI is affecting your engineering team with Cortex's AI Impact Dashboard

Rolling out a powerful AI tool like GitHub Copilot is a big win for any engineering leader. But because it’s such a significant investment, leadership will inevitably ask if it was worth the cost. Until now, answering this was nearly impossible. While GitHub provides adoption stats, connecting that data to real-world performance metrics like cycle time or code quality has been a manual, frustrating process. We built the Cortex AI Impact Dashboard to provide a clear answer.

Your metrics, your way: Announcing custom views in Engineering Intelligence

Every engineering organization measures success differently. A dashboard that’s perfect for one team might be meaningless for another. While out-of-the-box views for DORA are a great starting point, leaders need the ability to define and share the specific combination of metrics that matter most to their business. Without this, you're either forcing your teams to conform to generic reports or wasting time rebuilding the same views every week.

Announcing the AI chief of staff for engineering leaders

You see MTTR creeping up, but you don’t know why. You could ask your teams, but that means meetings, pulling people off projects, and waiting days for answers. What if you could just…ask? We’re excited to introduce the new strategic AI chief of staff for engineering leadership, powered by the Cortex MCP. By connecting your Engineering Intelligence data with your scorecards and standards, the MCP allows you to have a strategic conversation about your organization’s performance.

Introducing Magellan: The AI data engine that builds your IDP

Building a catalog used to be a project. It meant months of tracking down owners, untangling dependencies, and manually piecing together a picture of your architecture. It was a tedious, thankless process that delayed the value of your Internal Developer Portal (IDP) before you even got started. Now, it’s a coffee break. We’re excited to introduce Magellan, our new AI-powered data engine designed to build your catalog and get your IDP live in minutes.

A new era for your developer portal: The Cortex MCP is now generally available

Here's a scenario every on-call engineer knows too well: a critical incident fires for a service you’ve never seen before. Your first ten minutes are a frantic scramble across wikis and Slack channels just to answer the most basic questions: Who owns this? What does it do? Where are the runbooks? By the time you’re oriented, the incident has escalated.

Eng Intelligence | Cortex

Unlock the power of Engineering Intelligence with Cortex. In this video, we explore how engineering teams can leverage data, insights, and best practices to improve developer productivity, accelerate software delivery, and scale platform engineering. What you’ll learn in this video: Cortex delivers visibility across your entire ecosystem—helping teams adopt best practices, reduce bottlenecks, and align engineering with business outcomes.

How engineering leaders can adopt and lay the foundation for AI with confidence

AI is transforming how software is written and operated. Every day, engineering teams are discovering new ways to accelerate development, reduce toil, and push the boundaries of innovation. But this acceleration makes it easy to forget a fundamental truth: speed without guardrails creates risk, especially when implementing the AI-powered tools that dominate today's news cycles.

The future of IDPs in an AI-first world

Over the last few months, I’ve had countless conversations with my peers about one topic: the rise of AI coding assistants. I know this isn’t exactly breaking news, and I’m sure you’ve had these conversations as well. But there’s a reason the common coffee chat today is 10 percent small talk and 90 percent about the AI-first world that we live in. Tools like GitHub Copilot, Cursor, and Devin are fundamentally changing how we write software.

Onboarding with Cortex

Onboarding to Cortex has never been easier. In this video, discover how Cortex and Magellan, our AI-powered data engine, make it possible to go from a blank slate to a fully functional internal developer portal in just minutes, not months.
