    Why this exists

    The work shouldn't take
    a license and a Tuesday.

    A small editorial argument for free, browser-based civic tooling.

    Urban planning runs on public notice: the legal obligation to tell every neighbor within 300, 500, sometimes a thousand feet that something is changing on their block. The public notice mailing workflow turns that requirement into a deduplicated owner list and a sheet of Avery 5160 labels.

    The work to do it correctly lives behind enterprise GIS licenses, Tuesday-afternoon trainings, and PDFs that haven't been updated since 2014. UrbanKit Studio replaces that with nine browser tools. Free, no signup. Bulk and API volume are the paid part.
