Connect your data

Point Skeyenote at any JDBC source, Hive metastore, S3-compatible lake, or local files. No data movement required.

Write, run, iterate

Cells execute on your Spark cluster in real time. Inspect DataFrames, chart distributions, and refine logic cell by cell.

🔬

Share findings

Export annotated notebooks as live reports. Markdown cells let you embed context alongside your code and outputs.

What you get

Everything a data team
actually needs

Skeyenote keeps the full power of Spark within reach — without infrastructure headaches or context-switching between tools.

Massive Parallel Execution

Every cell dispatches jobs to your Spark cluster. Shuffle hundreds of millions of rows while you read the partial results streaming into the output pane.

🔗

JDBC Connectivity

Query Postgres, MySQL, Oracle, Hive, Trino, or any JDBC-compliant store without leaving the notebook. Schema introspection included.

📝

Markdown Cells

Narrate your analysis inline. Toggle between code and markdown to build self-documenting notebooks that communicate as well as they compute.

🐚

Shell Interpreter

Run sh cells for data downloads, file management, or CLI tools — all from the same interface, without switching terminals.

Variable Inspector

Inspect DataFrame schemas, row counts, and column statistics without extra code. The variable panel updates live as each cell completes.

🤝

Team Notebooks

Share notebooks with your data team, leave comments, and revisit checkpointed cell states — exploratory work that doesn't disappear after the session ends.

20 built-in interpreters

One notebook,
any data source.

Switch interpreter per cell. Query Spark, relational databases, NoSQL stores, search engines, statistical tools, and more — all within a single notebook session, without leaving the interface.

Apache Spark at the core

Scale from laptop
to data center

Skeyenote talks directly to your Spark cluster. As your data grows, add executors — your notebooks stay the same. No rewrites, no migration.
