pluto is a compute cloud for exploratory financial data analysis. Jupyter notebooks created on pluto.studio are processed, uploaded to the creator's github account as plutons for sharing and versioning.
See pluto/presentation for the motivation behind it.
plutoPy provides the data-model for accessing financial data-sets cached in the compute cloud. For examples, see the Using articles on pluto/rtd and sample notebooks on pluto/docs-py.
