# 0. Capture OS

#### 0.1 What is Capture OS (ex-SpreadNet)?

**Capture OS** is a Solana arbitrage operating system.

At its core, it does one thing extremely well:

> **Continuously scan Solana DEXs for price inefficiencies and surface them in a clean, machine- and human-readable way — without ever touching your funds.**

The stack is split in layers:

* **Capture Engine**\
  The open-source detection core (the `capture` repo). It fetches quotes from multiple Solana DEXs/aggregators, normalizes them, calculates net spreads, filters noise, and outputs ranked opportunities in real time.
* **Capture Terminal**\
  The interface layer. This includes:
  * The **CLI terminal** you run locally.
  * The **hosted live feed** (web UI) that shows a real-time stream of opportunities and system stats.
* **Capture Bot** (optional product layer)\
  An automated execution engine that sits on top of Capture Engine, adds risk management and MEV-aware routing, and actually sends transactions. This is **not** part of the open-source repo; it’s the “automation on top”.

So the mental model:

* **Capture Engine** → finds edges
* **Capture Terminal** → shows edges
* **Capture Bot** → acts on edges

You can use any subset of these depending on who you are and what risk you want to take.
