## What it is
Timesketch is an open-source web application for collaborative forensic timeline analysis, developed by Google. It lets DFIR investigators organize, search, and annotate event timelines together in shared sketches.

## Use cases
- analyze forensic timelines from multiple data sources
- collaborate with a team on incident response investigations
- tag and annotate events in security timelines
- search large event datasets during DFIR investigations
- share investigation timelines with collaborators

## When to choose
- you need a collaborative tool for digital forensics and incident response timeline analysis
- you want to organize, search, and annotate large event timelines with a team
- you need a self-hosted, open-source alternative for forensic timeline review

## When to avoid
- you need a simple single-user log viewer without collaboration features
- you are not doing forensic or security timeline analysis
- you cannot run a self-hosted server with a search backend

## Facets
- artifact type: application
- maturity: active
- function: search-engine, analytics, data-visualization, security
- domain: security, developer-tools, analytics
- platform: self-hosted, python
- tags: dfir, forensics, timeline-analysis, incident-response, collaboration, linux, docker, web-server
