## What it is
FLAME is an Elixir library that lets you auto-scale parts of an existing application by wrapping code blocks in a FLAME.call, which executes them on short-lived copies of the app. It handles elastic pool scaling up and down with pluggable backends such as Fly.io.

## Use cases
- run CPU-heavy tasks like ffmpeg thumbnail generation on temporary servers
- auto scale parts of my existing app with a single function call
- offload expensive background work without a separate worker service
- boot ephemeral copies of my app to run a block of code
- scale to zero for bursty workloads in Elixir
- run async jobs on short-lived infrastructure

## When to choose
- you have an existing Elixir/Phoenix app and want elastic scaling without extracting services
- you need to run the full application context (DB connections, deps) for a task
- you want scale-to-zero pools with automatic idle shutdown

## When to avoid
- your stack is not Elixir/Erlang
- you need a general-purpose job queue rather than ephemeral in-place execution
- you deploy on platforms without a supported FLAME backend
