Github

What is GitHub?

GitHub is a developer platform for hosting Git repositories, reviewing code, automating builds and deploying software, used by individual developers, open source projects and enterprises. It combines repositories, pull requests, issues, GitHub Actions CI/CD, security scanning and the Copilot AI coding assistant. Plans run from a free tier to Enterprise.

Key features of GitHub

• Repositories and pull requests: Git hosting with pull requests, stacked pull requests and protected branches.
• GitHub Actions: CI/CD with GitHub-hosted and self-hosted runners and workflow templates.
• Issues and Projects: planning boards and tables linked to code.
• Copilot: AI code completion, Copilot code review and a CLI.
• Security: Dependabot, code scanning, secret scanning and Copilot Autofix for supported alerts.
• Codespaces: cloud development environments, billed as an add-on.
• Marketplace and APIs: extend workflows with apps, webhooks and APIs.

How GitHub works

Developers push code to repositories and open pull requests, where teammates review changes and automated checks run in GitHub Actions. Merged code can be built, tested and deployed through workflows. Security scanning runs on the same repositories, and organizations manage access, rules and audit through the Team and Enterprise plans.

Who uses GitHub?

GitHub is used by developers, startups, nonprofits, enterprises and public sector teams, including in healthcare, financial services and manufacturing. Open source projects commonly host there on the free tier. Larger companies adopt Enterprise for SAML single sign-on, SCIM, audit logs and data residency.

GitHub pricing

GitHub Free is $0 with unlimited public and private repositories and 2,000 CI/CD minutes per month. Team is $4 per user per month and adds 3,000 minutes and repository rules. Enterprise is $21 per user per month and adds Copilot access, SAML single sign-on, SCIM, data residency, SOC 1 and SOC 2 Type 2 reports and 50,000 minutes. The vendor offers a 30-day trial that bundles Enterprise, Copilot and Advanced Security. Codespaces starts at $0.18 per hour.

GitHub integrations

GitHub Marketplace lists actions and apps that extend workflows, and GitHub provides APIs and webhooks for custom integrations. It also offers an MCP Registry, the GitHub CLI and GitHub Desktop.

GitHub alternatives

GitLab is an all-in-one DevOps platform that can be self-managed and bundles CI/CD and planning in one product. Bitbucket is Atlassian's Git host and fits teams already using Jira. The row's listed alternatives, such as CockroachDB and SigNoz, are databases and observability tools, not code hosts.
