# Introduction

> Orwel documentation: the SDK, Dev mode, integrations, the REST API and the MCP server.

## Welcome to Orwel

Orwel is an event analytics SDK for startups, developers and vibe coders that maps feature adoption and conversion funnels, and feeds the results back to AI agents through MCP. The SDK captures visits, events and conversions; Orwel shows how people move through your journeys and features, scores every lead and ties it to the campaign that brought it. To build on top of it, use the REST API or connect an AI agent through MCP.
