What is GitHub?
GitHub is a cloud-based platform for version control and software development collaboration. Built on Git, it lets developers store code in repositories, track every change over time, review each other's work through pull requests, and automate build and deploy pipelines with GitHub Actions. Microsoft acquired GitHub in 2018, and the platform now hosts over 150 million users across more than 420 million projects.
Core Features
- Repositories & version control — Unlimited public and private repos on all plans. Full Git history, branching, and merging.
- Pull requests & code review — Structured review workflow with inline comments, required reviewers, and draft PRs. Team plan adds protected branches and code owners.
- GitHub Actions (CI/CD) — Event-driven automation that builds, tests, and deploys on push, PR creation, or any custom trigger. Free for public repos; private repos get a monthly minute quota depending on plan.
- GitHub Projects — Built-in project boards and tables for tracking issues and pull requests. Works like a lightweight Kanban board — no external tool needed for basic sprint tracking.
- GitHub Copilot — AI code assistant available as an add-on. Free tier includes 2,000 completions and 50 chat requests per month. Paid tiers start at $10/user/month.
- Security scanning — Dependabot automatically opens PRs for vulnerable dependencies. Code scanning with CodeQL available on all plans for public repos; GitHub Advanced Security is an enterprise add-on.
- GitHub Marketplace — Thousands of third-party integrations including Slack, Jira, VS Code, and most major CI/CD and cloud deployment tools.
How Remote Teams Use GitHub
GitHub is purpose-built for async work. A developer in Kuala Lumpur pushes a branch at 11pm. A reviewer in Singapore picks it up at 9am the next morning, leaves comments, and requests changes — all without a single meeting. The pull request thread is the conversation. The commit history is the audit trail. Remote engineering teams use GitHub Issues to track bugs and feature requests, GitHub Projects to run sprints, and GitHub Actions to automate everything from linting to production deploys. Teams that also use Slack or Microsoft Teams can connect GitHub notifications directly into their channels.
Who Gets the Most Out of GitHub?
Software engineering teams of any size — from a solo developer building in public to a 10,000-person enterprise with compliance requirements. Open source maintainers get the full feature set free. Startups on the Team plan at $4/user/month get protected branches, required reviewers, and 3,000 CI/CD minutes per month, which covers most small team needs. GitHub is not the right tool for non-technical teams who need project management without code — use Linear, Jira, or Notion instead.
