Vaex

Out-of-core DataFrames for exploring large datasets

About Vaex

A Python library for lazy out-of-core dataframes, visualising and exploring big tabular datasets with memory mapping, efficient filtering and fast aggregations without loading everything into RAM. It is free and open source, so teams can self-host it, inspect the code and adapt it to their own infrastructure without licence fees or vendor lock-in. Typical users run it alongside existing workflows to cut manual effort, improve visibility and keep full control over data, configuration and upgrades over time.
