Skatting — 2D Continuous Estimation for Agile Teams

A real-time, peer-to-peer estimation tool that replaces discrete planning poker with two-dimensional continuous input. Users position a log-normal "blob" on a plane where X = effort and Y = certainty — capturing both the estimate and confidence in a single gesture.

Fully serverless — peers connect directly via WebRTC, signaled through Nostr relays and MQTT. Deployed as a single static HTML file.

Why?

Traditional planning poker forces discrete values (1, 2, 3, 5, 8…) and ignores uncertainty. Skatting lets estimators express:

• How big they think the work is (horizontal position)
• How sure they are (vertical position — which controls the blob's spread)

The blob shape follows a log-normal distribution, reflecting how software estimates actually behave: bounded at zero, right-skewed, with a long tail.

Quick Start

npm install
npm run dev

Open the displayed URL, create a room, and share the link with your team.

Tech Stack

Development

npm run dev          # dev server
npm run build        # production build (single HTML file)
npm run check        # type checking (svelte-check + tsc)
npm run lint         # biome check
npm run test         # run tests

How It Works

1. One person creates a room and shares the link
2. Each participant drags their blob to express effort + certainty
3. When everyone is ready, estimates are revealed simultaneously
4. A combined distribution shows the team's consensus (or disagreement)

All communication is peer-to-peer — no estimation data touches a server.
