Hub by Pivotal Labs
Free applets that never see your data.
37 small applets for the jobs that get in the way of the work. Every one of them runs inside your browser, so whatever you paste or drop in stays on your machine. No account, no upload, no catch. They are built by Pivotal Labs, mostly because we needed them ourselves.
Data you have to clean before you can use it
Exports that disagree with each other, lists nobody owns, and the tidying that always lands the week before a migration.
