## What it is
FireDBG is a time travel visual debugger for Rust that records program execution and lets developers inspect call trees, variables, and timelines in VS Code. It consists of a CLI, a debugging engine built on LLDB, a source parser, and an indexer that stores breakpoint events in SQLite.

## Use cases
- debug a rust binary with time travel debugging
- visualize the call tree of a rust program
- trace variables and expressions during rust debugging
- debug rust unit tests and integration tests
- inspect multi-threaded rust program breakpoint events
- record rust program execution and query events via sqlite

## When to choose
- you need to understand complex control flow or data flow in a rust program
- you want to step backward through execution instead of rerunning repeatedly
- you debug multi-threaded rust code where traditional breakpoints are hard to coordinate
- you want to inspect variable values at any point in a recorded run

## When to avoid
- your project is not a cargo workspace
- you need debugging on native Windows (only WSL 2 is supported)
- you need a lightweight debugger without recording overhead
- you work primarily in languages other than rust

## Facets
- artifact type: cli-tool
- maturity: active
- function: testing, developer-tools, parser
- domain: developer-tools, programming-languages
