A CLI tool for pinpointing which package version introduced a bug or regression in your project.

Python's binary search library for JavaScript

Delta debugging over git change regions — which hunks of your dirty diff broke the test? These, isolated, at commit-below granularity where git bisect cannot reach.

Utility for searching and inserting elements in a sorted array using a binary algorithm

It's like the npm-check-updates "doctor" mode made for the pnpm update command, only faster

Code coverage for OCaml and Reason

git bisect for the inside of a lockfile diff. When a batch dependency update breaks CI, isolate the exact culprit package@version in O(log n) installs.

Sorted containers: SortedList (with duplicates), SortedSet, SortedMap. O(log n) bisect, rank, floor/ceiling, range queries. Port of Python sortedcontainers. Zero dependencies, TypeScript.

git bisect, but for dependency updates — find the minimal set of dependency changes (npm, pnpm, yarn, Cargo, Go, uv, Composer, pip) between two commits that breaks your build, and prove it's minimal.

find release that introduces a bug

Automatically find the exact commit, author, and lines that broke your tests. No more git bisect by hand.
