-| [asv](https://asv.readthedocs.io/en/stable/) | A tool for benchmarking Python packages over their lifetime. Allows you to write benchmarks and then run them against every commit in the repository, to identify where performance increased or decreased. Comparative benchmarks can also be run, which can be useful for [running them in CI using GitHub runners](https://labs.quansight.org/blog/2021/08/github-actions-benchmarks). | <span class="label label-green">Best</span> |

+| [pytest-benchmark](https://pytest-benchmark.readthedocs.io/en/stable) | Provides a `benchmark` fixture with full `pytest` integration. A simple, light-weight alternative to `asv`, for cases that don't require tracking performance over many commits.                                                                                                                                                                                                          | <span class="label label-yellow">Good</span> |
