Lines where the two differ have a tinted background and bold values. Where the data itself says which value is better (more marketplaces, a larger figure of the same marketplace, a fresher release, a verified mark on a marketplace that lists both), the better one is also marked green with ▲ and the worse one red with ▼. Where it runs, the transport, the tools, the settings, hooks, the bundle's parts, the licence and the week's changes are marked only as different: more or fewer is not better in itself.
What each says it does
vibelearn
VibeLearn silently watches your Claude Code sessions, extracts the concepts you encounter while building, and turns them into personalized quiz questions — so you actually retain what you learn. After each session, run `vl quiz` to review with adaptive spaced repetition across 7 question formats (multiple choice, spot the bug, code reading, fill in the blank, open-ended, true/false, ordering). Difficulty adjusts automatically: 3 correct answers in a row promotes you to the next level, one wrong answer drops you back. Senior-level open-ended answers are evaluated by a 5-dimension AI rubric.
witness
Distills your sessions or any text corpus into a dated history of how its subject changed.
