Efficiency through tooling.

How Semami is built

What our tools have in common

  1. Native

    Mac apps written for the Mac, not a web page in a window.

  2. Text first

    Your work is plain text, in files you can read, diff and keep in version control.

  3. On your Mac

    Everything runs locally and works offline. No account and no analytics; the only thing sent is a crash report.

  4. Paid once

    One purchase on the Mac App Store. No subscription and no in‑app purchases.

Company

Where the company comes from

Webzakimbo’s capability comes from years of consultancy: designing systems, delivering software, building cloud platforms and writing native Mac apps alongside client engineering teams. That work shapes the tools we make.

We are not taking on new consulting clients at the moment.
