## What it is
Mainframer is a CLI tool that executes a command on a remote machine while syncing project files back and forth over SSH. It offloads heavy operations like compilation from a local computer to a more powerful dedicated machine.

## Use cases
- run builds on a faster remote machine instead of my laptop
- offload compilation to a dedicated build server
- execute gradle builds remotely and sync results back
- run heavy batch processing or media encoding on another machine
- keep my laptop cool while builds run elsewhere

## When to choose
- you have access to a powerful remote machine and a slow local one
- your builds or batch jobs cause freezes or fan noise on your workstation
- you want a simple SSH/rsync-based remote execution tool without complex infrastructure

## When to avoid
- you need distributed CI/CD rather than a single remote machine
- your project files are too large for frequent rsync round-trips
- you need active development support - the 3.x Rust rewrite is still in progress and the project sees limited activity
