# Why you'd want a third-party UI for Polymarket

**Polymarket's official interface is fine. So why does a separate terminal exist? Same reason a Bloomberg Terminal existed for stocks that already had a broker UI.**

Every major exchange in every asset class has a native web UI aimed at first-time users, plus a separate ecosystem of trading terminals aimed at people who trade it professionally. Prediction markets are no different.

## The tension inside every native UI

An exchange's official interface has to serve everyone: the total newcomer who just heard about prediction markets, the semi-serious weekly trader, the pro. That means it has to explain concepts, hide power features behind dropdowns, and default to safety over speed. All good decisions — but they add friction for anyone past step one.

## What a terminal is optimized for

  - **Density.** More live info per pixel. Bloomberg-style, not consumer-app.
  - **Speed.** Keyboard-first, one-tap actions, latency measured in milliseconds.
  - **Composability.** Custom agents, BYO API keys, webhook exports, programmable rules.
  - **Risk plumbing.** Loss limits, position sanity checks, TP/SL that the exchange itself doesn't offer.
  - **Cross-market lens.** Whale leaderboards, correlation views, event clusters — things that need external context on top of exchange data.

## Non-custodial is the point

A terminal is trust-minimized. You keep your money on the exchange. We only add UX on top. If Polyterminus disappeared tonight, your Polymarket balance and positions would be exactly where you left them — because they never left Polymarket in the first place.

## We use Polymarket's public APIs

Everything the terminal shows — markets, prices, order book, whale positions, resolution outcomes — comes from Polymarket's public Gamma, CLOB, and data-api endpoints. Our own backend adds enrichment (technical indicators, trader-type classification, AI briefs), but the source-of-truth data is always Polymarket's.
