The branch was dead. No commits in weeks. But your proof of concept lived there, locked away like an unfinished thought. You needed it now. You needed git checkout poc.
When you run git checkout poc, Git moves your working directory to the poc branch. Every file, every line of code becomes exactly what it was on that branch. It’s the fastest way to switch back to an early experiment or revive a project idea you parked months ago.
A proof of concept branch is where ideas breathe without slowing down production. You can isolate changes, push prototypes, and test them against real conditions. When a POC pays off, you can merge it into the main branch. When it fails, you can abandon it without damage.
Sometimes, the branch doesn’t exist locally. In that case:
git fetch
git checkout poc
This fetches the latest references from origin and switches you there. If the branch is remote-only, you create it locally with:
git checkout -b poc origin/poc
Clean checkouts matter. Before you switch, commit or stash your current work. Uncommitted changes can block you from checking out the POC branch, or they can pollute it with unrelated edits.
Once you’re in, test fast. Run your scripts. Break what needs breaking. Measure what you need to measure. A POC is a decision-making tool, not a long-term codebase.
Version control was built for this rhythm. Git flows best when branches are short-lived and focused. The moment a proof of concept is done, decide its fate. Merge and deploy, or delete and move on. This keeps repositories light, histories clean, and teams fast.
If you want to see how quick testing and iteration can be, push your POC live in minutes. Connect it to a real environment without drowning in setup or infrastructure. Try it on hoop.dev—your git checkout poc can be live before the coffee cools.
