# Replay And Inspect WARC Web Archives Before Investigation Or Migration With Pywb

Replay WARC-backed web archives locally so an agent can inspect historical pages, validate captures, and review preserved site behavior before migration or investigation work.

## Prerequisites

Python 3, pip

## Installation

Use the upstream install or setup path that matches your environment:
- pip install pywb
- git clone https://github.com/webrecorder/pywb
- To install from a locally cloned copy, install with pip install -e . or python setup.py install.

Requirements and caveats from upstream:
- **pywb** is a Python 3 web archiving toolkit for replaying web archives large and small as accurately as possible.
- Note: depending on your Python installation, you may have to use pip3 instead of pip.
- To run tests, we recommend installing pip install tox tox-current-env and then running tox --current-env to test in your current Python environment.

Basic usage or getting-started notes:
- ---------------------------
- On Linux-based systems, first verify that python3-dev is installed. If it is not, install it with your package manager. E.g. on a Debian-based system, use:
- sudo apt install python3-dev
