## What it is
TimeCat is an open-source web page recording library that captures browser interactions (DOM, canvas, audio, mouse, scroll) and replays them losslessly like a video player, without generating actual video files. It ships as npm packages (recorder and player modules) plus a Chrome extension for one-click record and export.

## Use cases
- record browser sessions and replay them like video
- capture user interactions on a web page losslessly
- export a web recording as a self-contained HTML file
- record canvas and WebGL activity in the browser
- add session replay to a web app
- record a webpage with audio narration
- replay recorded web sessions with fast-forward and seeking

## When to choose
- you need lossless, DOM-based web session recording instead of screen-capture video
- you want small storage footprint for ultra-long recordings
- you need a player with seeking, speed control, and heat points
- you want a Chrome extension for quick one-click recording

## When to avoid
- you need actual video files (mp4/webm) as output
- you need a stable, production-hardened API - the docs warn the API may change
- you need cross-browser support beyond modern Chromium/Firefox/Safari versions
- you need active maintenance - the last release was early 2023
