Comparison and usage of Poetry and Rye: Python project management options

Poetry has long been a popular tool for dependency management and package publishing in Python projects. However, recently, a new tool called Rye has been attracting attention because it enables faster and simpler operations.

In this article, we will compare Poetry and Rye, organize Rye’s unique functions and design philosophy, and summarize in what situations you should consider migrating.

Correspondence between basic functions of Poetry and Rye

Below is a correspondence table of Poetry and Rye commands for the main functions.

Main function correspondence between Poetry and Rye

function	Poetry	Rye	remarks
Project initialization	poetry init	rye init	Rye has a more concise dialogue format.
Add dependency	poetry add requests	rye add requests	--dev option is also supported.
Dependency deletion	poetry remove requests	rye remove requests
Create/update lock file	poetry lock	rye sync	Rye is faster with uv
package installation	poetry install	rye sync
script execution	poetry run python	rye run python
Virtual environment shell startup	poetry shell	rye shell
Python version specification	poetry env use 3.11	rye pin 3.11	Rye does not require pyenv and can be downloaded independently
Package release	poetry publish	rye publish	twine is not required and can be easily published

Rye-specific features and benefits

Rye has the following unique features compared to Poetry.

• Manage your own Python version:

  You don’t need pyenv or asdf because you can directly download and use that version with rye pin 3.12.

• Fast dependency resolution:

  It uses uv and is orders of magnitude faster than Poetry.

• Simple design and integrated CLI:

  Contains all the basic functions used in development, such as rye fmt (format), rye lint (static analysis), and rye test (test execution).

• Self-update command:

  rye self update allows you to always keep rye up to date.

Guidelines for deciding whether to introduce

You may want to consider migrating to Rye from the following points of view.

Cases in which you should consider migration

Judgment criteria	explanation
Need fast dependency resolution	Aim to reduce waiting time in large-scale projects and CI
Switching Python versions frequently	Flexible management possible with Rye’s pin
I want to start a new project simply.	Simple configuration files and configuration

On the other hand, it is practical to continue using Poetry in the following cases:

Cases in which you should avoid migration

Judgment criteria	explanation
Currently in stable operation with Poetry	No need to force the switch
The team and CI are designed with Poetry in mind.	Prioritize smooth operations

summary

Poetry and Rye are similar and different tools. Both are excellent options to support modern Python development, but it’s important to understand the characteristics of each and use one depending on the needs of your project.

Although Rye is still a new tool, its lightness and sense of unity are appealing, and it has the potential to become mainstream in the future. A good approach is to try it out with a small new project first.
