One person built this. On purpose.

Larssoni is made by Oscar Wirén, an independent maker in London. It does one job: it gives the dashboard you already made a home.

For years I made dashboards for other people, then watched them die the moment I sent them: a login wall, a blank page, or a PDF that was wrong by Tuesday. The work was good. Getting it in front of someone was the part that kept breaking.

So I built Larssoni to fix exactly that. The hard part was never making the dashboard — you already did that, and it’s good. The hard part is giving it a home: a link that always opens, for exactly the people you choose, with numbers that keep themselves up to date from your spreadsheet. That’s the whole product, and I kept it that focused on purpose.

I try to be honest about the edges. Some dashboards can’t update themselves, and you’ll know before you pay. If you stop paying, here is exactly what happens. Links anyone can open keep working. Links you locked to chosen people pause until you pay again. You can export or delete everything in one click — no email to support, no dark patterns. I’d rather under-promise than have you feel misled.

What got built this week.

This is a real Larssoni dashboard about building Larssoni. It reads a Google Sheet every morning; I only ever edit the sheet.

Larssoni — built week by week: a live dashboard reading commits, tickets opened and tickets closed from a connected Google Sheet, refreshed every morning.
