pse — Python Search Engine

Find Python packages across PyPI, Conda channels, and other compatible indexes.

pse is a cross-source command-line Python package search tool. It searches Python packages without installing packages or using a package manager at runtime.

Features

  • Search PyPI and conda-forge from one command.
  • Add extra PyPI Simple indexes and Conda channels.
  • Produce human-readable tables or structured JSON.

Usage

Using pse on-the-fly

You can run pse directly with uvx, pipx or pixi exec for a quick search without installing anything.

uvx pse pkg
pipx 
pipx run pse pkg
pixi exec 
pixi exec pse pkg

Installing pse for repeated use

You can install pse as global command with uv tool install for repeated use:

uv tool install pse
pse pkg

Use-cases

Search for a package on PyPI and Conda:

pse pkg

Search an additional PyPI index:

pse pkg --pypi-index https://download.pytorch.org/whl/cu126

Search an additional Conda channel:

pse pkg --conda-channel bioconda

Use multiple extra sources:

pse pkg --pypi-index https://download.pytorch.org/whl/cu126 --conda-channel bioconda

Sources

PyPI

pse searches the PyPI Simple API. Additional PyPI indexes must expose a compatible Simple index, such as the PyTorch wheel index.

Conda

pse searches current_repodata.json.bz2 for the selected Conda channel and platform. It also searches noarch unless the requested platform is already noarch.

Channel names are resolved through conda.anaconda.org. Full channel URLs are also accepted.

The reduced current_repodata metadata is fast, but it may not contain every historical Conda package version.

JSON output

pse can produce structured JSON output for programmatic consumption and agent friendly use. The JSON output contains a results array with one entry per source. Each entry contains the source name, package name, and an array of available versions.:

{
  "query": "torch",
  "platform": "win-64",
  "results": [
    {
      "source": "pypi",
      "name": "torch",
      "versions": [
        {
          "version": "2.13.0",
          "build": null,
          "platform": null
        }
      ]
    }
  ]
}

If a source fails, an errors array is added to the document.
