How to read a GitHub repo as a non-technical founder.
An agency shows you their GitHub portfolio. You nod politely. You have no idea what you are looking at. This guide fixes that — no coding required.
Why GitHub is the best due diligence you can do.
A portfolio website is marketing. A GitHub repository is evidence. Every commit is timestamped and immutable. The history cannot be faked. When a developer or agency gives you a GitHub link, they are handing you a forensic record of how they actually work.
Most non-technical founders skip this step because they think it requires coding knowledge. It does not. What you are looking for are patterns — and patterns are readable by anyone.
The five things to look at immediately.
Click the "commits" number near the top of any repo. A healthy project has commits that are small, frequent, and have descriptive messages like "fix: handle null user on login" — not "wip" or "asdfgh" or 47 commits all pushed in one 3 AM burst. Sporadic huge pushes mean work happened somewhere else and was dumped in. That is not how professionals ship.
A README is the front door of a project. It should explain what the project does, how to set it up, and how to run it. Missing README or a README that just says "TODO" means the developer does not document their work. On a client project, that means you will have no handover, no explanation of decisions, and no way to onboard a second developer without starting from scratch.
The date of the most recent commit tells you whether the portfolio is maintained or abandoned. A repo last touched in 2019 that is being shown to you in 2026 is not evidence of capability — it is evidence of a developer who has not worked on a public project in seven years. Healthy developers stay active. Look for repos updated in the last 12 months.
Click the "Issues" and "Pull requests" tabs. Open issues with no comments or responses signal a developer who ignores problems. Closed pull requests show how they collaborate — do they review each other's code? Do they leave explanatory comments? A solo developer with zero PRs is not using best practices. For an agency, no PRs means no code review culture.
You do not need to read the code. Look at how it is organised. Are files named clearly? Is there a logical folder structure (src, tests, docs)? Or is everything dumped in the root folder with names like "final_v3_REAL.js"? Organisation signals professionalism. A messy repo is a messy developer.
Red flags in plain language.
Work happened elsewhere and was bulk-dumped. They are hiding the actual process.
No discipline. On your project, bugs will be unfindable in history.
Nothing is tested. Works on their machine. Breaks in production.
Basic hygiene missing. Secrets may have been accidentally committed.
Either fake portfolio or one person doing everything. Neither is good.
Cannot verify anything they claim. Acceptable if they show you private repos directly.
What good looks like.
A GitHub profile worth trusting has: regular commits spread over weeks and months, descriptive commit messages that read like a changelog, a README on every project, open-source contributions to other projects (a sign they engage with the broader community), and clear evidence of collaboration through pull requests and code reviews.
You are not trying to understand the code. You are trying to understand the habits. Habits do not change project-to-project. A developer who writes sloppy commits in their open-source work will write sloppy commits on your codebase.
“Can you walk me through a recent commit in this repo and explain why you made that decision?” A strong developer will light up. A developer who copied from Stack Overflow will not know what to say.
