Vizier is a notebook that puts your data front-and-center.
Whether you prefer to use spreadsheets, notebook scripting, or databases, Vizier makes it easy to to explore the data to find out what you have, validate that the data makes sense, and transform it to fix bugs and mold it into a form your tools can use.
There is a lot of hate for some popular notebooks. Unlike most popular notebooks, Vizier is multi-lingual and multi-modal, letting you edit your data through the best interface for what you're trying to do. On top of that, it tracks provenance of your data and automatically versions your workflows. Vizier also uses dependency analysis to make sure you're never looking at stale outputs.
