BAD CLUSTER

0x0FFFFFF7  //  THE BAD_CLUSTER MARKER

We never grew out of taking things apart to see how they work.

Side projects that got out of hand, on purpose.

144 clusters scanned · 4 marked bad · the rest are fine

How we work.

01

Mark it, don't hide it

If something doesn't work, we say so - in the docs, in the UI, in the code comments. A known limitation beats a confident lie every time.

02

Built because we needed it

Everything here started as a real problem one of us actually had. Nothing is built speculatively for an audience that doesn't exist yet.

03

Open by default

Source, build process, and the reasoning behind decisions are public unless there's a specific reason they can't be.
