GitHub

What it does

GitHub hosts Git repositories and gives every project a home with issues, pull requests and code review. On top of hosting it runs GitHub Actions, which automates builds, tests and deployments when something happens in a repository. It also stores release artefacts and packages, and offers AI tooling through Copilot.

Why you would need it

Without it, code lives on laptops, changes are untracked and nobody can say who changed what, or why. When something breaks you cannot roll back with confidence, and a second person cannot safely contribute.

A pull request fixes this. Every change becomes a reviewable unit with a discussion attached, checks run automatically, and merging is a deliberate step. You get a durable, searchable history of every decision that touched the code. That matters even more when AI agents write part of the code, because every edit has to be reviewable before it ships.

Where it fits

GitHub is the spine of a delivery pipeline: branch, pull request, review, automated checks, merge, deploy. Hosting platforms such as Vercel, CI providers and AI coding tools mostly assume you are on it. It is also a clean home for docs and infrastructure config that benefit from version history.

It replaces local folders and ad hoc backups. It does not replace a planning tool, and it does not run your product once it is deployed. Issues work, but Linear or Jira are better for a serious roadmap.

What stands out

• Pull requests and code review are the benchmark other tools copy.
• Actions covers most CI/CD needs without a second tool.
• The ecosystem is wide, so integrations usually already exist.
• It has an official MCP server and a public REST API.

My take

For anything that involves code, I would start on GitHub. Even a solo project benefits from a trail of reviewable changes. The gravity is the product: being where contributors, tools and hosting already are saves more time than any single feature.

What I would watch is Actions. Workflows grow into YAML you maintain forever, and they can get fiddly as usage grows. It is also owned by Microsoft, which is fine for most teams but worth a conscious thought if vendor concentration matters. If you never branch and only want a backup of one folder, it is overkill.

Verdict

Pick GitHub if you ship code with more than one contributor, human or agent. Skip it as your planning tool, or if all you need is a backup.
