GitHub

GitHub crossed 180 million developers by late 2025 — adding 36 million in a single year, its fastest absolute growth rate. The platform hosts 630 million total repositories with 121 million new repos created in 2025. GitHub Copilot has 4.7 million paid subscribers as of January 2026, adopted by 90% of Fortune 100 companies.

GitHub Copilot is an AI coding assistant that generates 46% of the code written by developers who use it. It provides inline code completion, chat in the IDE and github.com, pull request summaries, and autonomous agent mode. Agent mode researches a repository, creates an implementation plan, makes code changes on a branch, and opens a pull request — completing straightforward GitHub Issues without a developer writing code. Copilot Business ($19/user/month) covers individual developers; Copilot Enterprise ($39/user/month) adds codebase-aware suggestions tuned to your internal code.

GitHub Actions is GitHub's CI/CD platform with 20,000+ marketplace Actions and YAML-defined workflows triggered by repository events. OIDC (OpenID Connect) federation allows GitHub Actions to authenticate directly to AWS, GCP, and Azure without storing cloud credentials as GitHub secrets. The cloud provider trusts GitHub's identity tokens; the Actions workflow requests a short-lived token at runtime. This eliminates long-lived IAM access keys or service principal secrets — a significant security improvement over stored credentials.

GHAS is a security toolset available on GitHub Enterprise and GitHub Teams plans. It includes: CodeQL SAST scanning that finds vulnerabilities in JavaScript, Python, Java, Go, C/C++, C#, and Ruby; secret scanning with push protection that blocks API keys and tokens before they're committed; dependency review showing vulnerable dependencies introduced in PRs; and Dependabot security update PRs for known CVEs. GHAS is licensed per unique committer (not per seat) making it cost-effective when applied to active repositories.

GitHub Free covers unlimited public and private repositories for individuals. GitHub Teams is $4/user/month (required status checks, branch protection, CODEOWNERS, protected branches). GitHub Enterprise Cloud is $21/user/month (SSO, SAML, audit log streaming, Enterprise Managed Users). GitHub Copilot Business is $19/user/month; Copilot Enterprise is $39/user/month. GHAS is licensed separately per-committer for Enterprise plans. Share your team size and requirements and we'll help you identify the right tier combination.

Key security practices: use OIDC authentication to cloud providers instead of stored secrets, pin Actions versions to commit SHAs (not tags) to prevent supply chain attacks, configure Dependabot for Actions version updates, use GitHub's secret scanning to detect exposed credentials, apply least-privilege permissions to the GITHUB_TOKEN, enable required code review for Actions workflow changes, and use environment protection rules to gate production deployments behind manual approval.

Codespaces are cloud-hosted development environments based on dev containers (.devcontainer.json). They provision in VS Code or browser with your full toolchain, extensions, and service containers. Use them for: eliminating 'works on my machine' issues across teams, enabling contributors and reviewers to test changes without local setup, providing consistent environments for contractors and new hires, and running development on machines that can't install local tooling. Codespaces are billed per core-hour of usage — typically less than $10/developer/month for active users.

Free: unlimited public/private repos, basic Actions minutes, basic branch protection. Teams ($4/user): required status checks, CODEOWNERS, draft PRs, protected environments, 3,000 Actions minutes/month. Enterprise ($21/user): SAML SSO, SCIM provisioning, audit log streaming, Enterprise Managed Users, IP allow lists, enterprise policies, 50,000 Actions minutes/month. Advanced Security and Copilot are add-ons at both tiers. Most commercial development teams benefit from Teams at minimum for protected branch enforcement.

We audit existing Jenkins pipelines, map them to GitHub Actions equivalents, and migrate in stages — starting with simpler CI pipelines and working toward complex deployment workflows. We configure OIDC authentication to replace Jenkins cloud credentials, implement reusable workflows for shared stages, and set up self-hosted runners for any workloads that need private network access. Jenkins-specific features (Groovy Shared Libraries, dynamic Kubernetes agents) have GitHub Actions equivalents that we design as part of the migration.

We offer GitHub managed support covering Actions workflow optimization, Copilot Enterprise configuration and policy management, GHAS remediation guidance, repository governance reviews, branch protection policy updates, and security incident response for exposed secrets. We also provide team training on GitHub Actions, Copilot best practices, and security hygiene.
