The path to better performance is often found in simplicity.

Recent attacks on open source focus on exfiltrating secrets; here are the prevention steps you can take today, plus a look at the security capabilities GitHub is working on.

/fleet lets Copilot CLI dispatch multiple agents in parallel. Learn how to write prompts that split work across files, declare dependencies, and avoid common pitfalls.

I used coding agents to build agents that automated part of my job. Here’s what I learned about working better with coding agents.

A look at GitHub Actions’ 2026 roadmap, outlining how secure defaults, policy controls, and CI/CD observability harden the software supply chain end to end.

Reviewed advisories hit a four-year low, malware advisories surged, and CNA publishing grew—here’s what changed and what it means for your triage and response.

From April 24 onward, interaction data—specifically inputs, outputs, code snippets, and associated context—from Copilot Free, Pro, and Pro+ users will be used to train and improve our AI models unless they opt out.

Learn how to integrate the Copilot SDK into a React Native app to generate AI-powered issue summaries, with production patterns for graceful degradation and caching.

CodeQL and AI‑powered detections work together in GitHub Code Security to identify vulnerabilities across more languages and frameworks.

As contribution volume grows, mentorship signals are harder to read. The 3 Cs framework helps maintainers mentor more strategically… without burning out.

An inside look at repository-native orchestration with GitHub Copilot and the design patterns behind multi-agent workflows that stay inspectable, predictable, and collaborative.

See how GitHub is investing in open source security funding maintainers, partnering with Alpha-Omega, and expanding access to help reduce burden and strengthen software supply chains.

AI automates triage for accessibility feedback, allowing us to focus on fixing barriers—turning a chaotic backlog into continuous, rapid resolutions.

In February, we experienced six incidents that resulted in degraded performance across GitHub services.

GitHub recently experienced several availability incidents. We understand the impact these outages have on our customers and are sharing details on the stabilization work we’re prioritizing right now.

AI is shifting from prompt-response interactions to programmable execution. See how the GitHub Copilot SDK enables agentic workflows directly inside your applications.

GitHub Agentic Workflows are built with isolation, constrained outputs, and comprehensive logging. Learn how our threat model and security architecture help teams run agents safely in GitHub Actions.

GitHub Security Lab Taskflow Agent is very effective at finding Auth Bypasses, IDORs, Token Leaks, and other high-impact vulnerabilities.

How Copilot code review helps teams keep up with AI-accelerated code changes.
