Explore the GitHub Copilot CLI and try interacting with Copilot directly from your terminal.

Now in technical preview, the GitHub Copilot SDK can plan, invoke tools, edit files, and run commands as a programmable layer you can use in any application.

Run tests, fix code, and get support—right in your workflow. Stay focused and let Copilot handle the busywork.

Learn how we are using the newly released GitHub Security Lab Taskflow Agent to triage categories of vulnerabilities in GitHub Actions and JavaScript projects.

Learn how I managed context to keep Copilot focused, used the Plan agent to sharpen vague requirements, and required Test Driven Development practices to catch bugs before users.

Copilot’s cross-agent memory system lets agents learn and improve across your development workflow, starting with coding agent, CLI, and code review.

User feedback led us to clean up outdated mitigations. See why observability and lifecycle management are critical for defense systems.

In December, we experienced five incidents that resulted in degraded performance across GitHub services.

Announcing GitHub Security Lab Taskflow Agent, an open source and collaborative framework for security research with AI.

AI is designed to help you do what you love most, not replace your expertise. Discover how developer feedback and real-world experience are shaping AI coding tools that keep you in control.

Learn how custom instructions, reusable prompts, and custom agents help GitHub Copilot deliver more accurate results.

Out of more than 700 games submitted to Game Off 2025, these ten winners stand out for creativity, craft, and bold interpretations of the WAVES theme. All are free to play, with source code available to explore.

AI is settling the “typed vs. untyped” debate by turning type systems into the safety net for code you didn’t write yourself.

Explore the GitHub Blog’s top posts covering the biggest software development topics of the year.

Learn why some long-enrolled OSS-Fuzz projects still contain vulnerabilities and how you can find them.
