Field notes from building kOS

Engineering, decisions and measurements from the platform our use cases run on, and the vertical products on top of it.

• DONNAJAMES and KlusAI: one platform for Dutch legal professionals

  One platform, built for more than 200 Dutch legal professionals. Powered by Claude, built on kOS, and production-ready in about twelve weeks from kickoff.

• Four sites, one tracker id, and three dashboards that said Setup pending

  One Django app serves four public sites. All four shipped the same analytics tracker id, so three products filed their traffic under a fourth, and the fix was less interesting than the reason we could not see it.
