There's no config or setup required, just pipe input to splash and it auto detects common log formats and adds color to make them easier to scan. You can mix and match multiple log formats in a single stream.

Regexp and string search is also built in.

I built Splash as I found it frustrating to scan and find a particular test/line while developing locally - I would often add "ASDF" or "####" to make lines stand out.

Splash's color scheme makes it easy to scan and find the zone you're interested in. Use string or regexp search to highlight individual log lines.
