What hackers pick instead
- Size of LifeA free interactive site comparing the scale of living things, praised for its art, music and polish. Critics mention the metric-to-inches switch and a consent window with many partners.30recommend
- PGSimCityPeople praise it as an engaging 3D visual tour of how PostgreSQL works internally. The most common complaint is that the screen is too busy and crowded with popups to follow.27recommend
- IthihāsasPeople like the relationship graph that maps how characters in the Hindu epics connect, and the polished UI. The most common caveat is low contrast and dense text that is hard to read.18recommend
- Now I Get ItTurns papers into interactive web pages that help visual learners get into new fields. Output quality varies, and daily limits are a common complaint.17recommend
- Transformer ExplainerPeople recommend it as a clear, interactive visualization for understanding how transformers and GPT-2 work.12recommend
