# git bisect

44 Hacker News commenters recommended git bisect and 5 criticized it, November 2025 to November 2026. It was recommended in 5 of 13 months. It meets the Hacker Approved badge rule.

**Verdict:** Recommended for pinning down the commit that introduced a bug, often faster than reading history. Main caveat: it needs a reliable good/bad test.

## Why people recommend it

- Pinpoints the commit that caused a bug (6 comments): "I once root-caused a revenue-losing bug that had the entire rest of my team stumped with ten minutes of git-bisect." ([source](https://news.ycombinator.com/item?id=48902960)) "Rather quickly, it'll point you to the commit that caused the regression." ([source](https://news.ycombinator.com/item?id=46602539)) "In the two cases I used it, it identified the individual commit." ([source](https://news.ycombinator.com/item?id=46603749))
- Faster than reading logs or code (4 comments): "with time to write a bisect script and half an hour to run the bisect session I was able to find the commit" ([source](https://news.ycombinator.com/item?id=45803828)) "It's often a lot faster to bisect than to read the log over the month or two since I touched something." ([source](https://news.ycombinator.com/item?id=45792274)) "Even if you can reason through a code base a bisect can still be much quicker." ([source](https://news.ycombinator.com/item?id=45792322))
- Runs unattended with a pass/fail script (3 comments): "Git bisect is a wonder, especially combined with its ability to potentially do the success/fail testing on its own" ([source](https://news.ycombinator.com/item?id=46603990)) "connected to a script that outputs good/bad, is one of computing's crowning achievements" ([source](https://news.ycombinator.com/item?id=48904250)) "The fact that it's noninteractive means that you can do other work in the meantime." ([source](https://news.ycombinator.com/item?id=45795774))
- Handles messy, tangled codebases (3 comments): "Git bisect was an extremely powerful tool when I worked in a big-ball-of-mud codebase" ([source](https://news.ycombinator.com/item?id=45792292)) "bisect is really handy because often a bug will have been introduced as a side-effect" ([source](https://news.ycombinator.com/item?id=45792828)) "--first-parent with bisect really helps when the history is messy." ([source](https://news.ycombinator.com/item?id=46602879))

## What people warn about

- Slow to set up or run (3 comments): "with time to write a bisect script and half an hour to run the bisect session I was able to find the commit" ([source](https://news.ycombinator.com/item?id=45803828)) "the search for bad commit is more lengthy and less informative than doing the normal experimental process" ([source](https://news.ycombinator.com/item?id=46608096)) "IMHO git bisect is slower, especially depending on the reload/hot-reload/compile/whatever process" ([source](https://news.ycombinator.com/item?id=46904582))
