It's Time to Rethink Untrusted Code in Your Pipeline | Harness Blog

The catastrophic TeamPCP exploit in March 2026 demonstrated that "open execution" models, in which third-party code runs with full privileges, have made CI/CD pipelines a primary target for global credential harvesting. There are better architectures. On March 19th, the risks of running open execution pipelines — where what code runs in your CI/CD environment is largely uncontrolled — went from theoretical to catastrophic.

Claude Livecaster Is Now Open Source, Plus a Two-Voice Broadcast Mode | CircleCI Loop Lab

Claude Livecaster is now public on CircleCI Research. In this update, Ryan Hamilton walks through the newly open-sourced repo, seven built-in simulation scenarios, and a new two-voice broadcast format featuring an anchor and a field correspondent narrating the action together. The demo scenario: Pipeline Wars, six CI pipelines racing across three providers, with Claude providing live color commentary on every Docker build failure, OOM kill, and production rollout.

We Made Claude Narrate an AI Model Race Like a Sports Commentator | Loop Lab

What if you didn't have to stare at logs while your AI agent worked? In this Loop Lab experiment, Ryan Hamilton built Claude Livecaster, a tool that gives Claude a live voice to narrate long-running agentic processes like a sports commentator. The demo: six AI models (GPT, Gemini, and Claude variants) race through a CI/CD benchmark, and Claude calls the whole thing play-by-play. Rate limit hits, comeback stories, photo finishes, all of it, out loud.

Winning in the AI Era: How Top Teams are Driving Their Velocity Gains with Alloy & Chime

While most teams struggle with the complexity of AI-generated code, Alloy and Chime have built internal cultures and processes that enable them to scale their development while maintaining quality. Join CircleCI’s CTO, Rob Zuber, in conversation with Maciej Makowski, Senior Software Developer at Chime, and Sunny Singh, Senior Software Engineer at Alloy, as they explore the dynamics that set their teams apart. They'll talk through the culture and delivery practices that actually moved the needle.

Announcing the Next Chapter for Bitbucket Pipelines Runners

In December 2025, we announced our intention to introduce pricing for self-hosted runners so we could provide stronger support and keep investing in new features and ongoing improvements. You’ve told us that having a free option is important. As a result, we’re introducing a new operating model that lets you continue using self‑hosted runners for free with the option to upgrade to a paid premium runners tier as your needs grow.

How to Plan a Successful CI/CD Migration Without Disrupting Developers | Harness Blog

Modern engineering teams run on CI/CD. It’s where pull requests get validated, artifacts get produced, and releases get promoted to production. That also makes CI/CD migration very risky because you're not just moving a "tool"; you're moving the workflow that developers use dozens or hundreds of times a day. The good news: disruption is optional.
