Tweakstreet supports JSON-like data trees as first-class data types. Other tools often operate at the level of flat records, making work on lists and nested data difficult. With Tweakstreet it's just natural to work with these data types.
You can design, preview, and run the all jobs through the GUI.
Tweakflow jobs can be scheduled and run unattended through the command line interface even on headless servers.
In other data processing tools, developers often have to hard-code the details of each processing step. In tweakstreet every configuration detail can be a context-sensitive expression.
As a consequence, you can much easier process data that is self-describing, or for which you maintain a config file or meta-data repository that describes how the data should be handled.
Move your mouse over the image to see the step configured with a layer of indirection that makes meta data driven solutions easy to create.
