It supports both rosbag1 (the original format) and rosbag2 (the newer format), and includes an extensible type system for serializing and deserializing message data. The library was developed for MARV robotics and can be used standalone or alongside ROS1 or ROS2 installations.\n\nThe package provides high-level interfaces for common tasks like reading messages from a bag file and deserializing them into Python objects, as well as command-line tools for converting between rosbag formats. Its dependencies are minimal and well-established (numpy, lz4, zstandard for compression, ruamel.yaml for configuration, and apsw for database access), making it straightforward to integrate into robotics data pipelines or analysis workflows.","worth_installing":"Yes. Rosbags is actively maintained, has no known vulnerabilities, supports current Python versions (3.10\u20133.14), and solves a real problem for robotics engineers who need to work with bag files outside a ROS environment. The pure Python implementation and low dependency footprint make it easy to integrate. Install it if you work with ROS data and need portable, lightweight bag file access."},"id":"rosbags","links":{"html":"https://skillfed.io/packages/rosbags","md":"https://skillfed.io/packages/rosbags.md","pypi":"https://pypi.org/project/rosbags/"},"maintenance":{"status":"active"},"meta":{"latest_release":"2026-08-12","license_spdx":"Apache-2.0","license_treatment":"permissive","name":"rosbags","python_support":"supports_current","summary":"Pure Python library to read, modify, convert, and write rosbag files."},"popularity":{"monthly_downloads":732647,"position":5201,"tier":"top_15000"},"security":{"n_vulnerabilities":0},"version":"0.11.4"}
