Rybbit for developers

Analytics that behaves like good software.

One script tag, or one npm package. A REST API for everything the dashboard shows, an MCP server your agents can operate, and a codebase you can read, audit, and run on your own server.

Install

One tag. Or one package.

Drop the script on any site, or install @rybbit/js and initialize it in two lines. Autocapture starts immediately; custom events are there when you want them.

Script docs
index.html
<script
  src="https://app.rybbit.io/api/script.js"
  data-site-id="YOUR_SITE_ID"
  async
></script>
app.ts
npm install @rybbit/js

import rybbit from "@rybbit/js";

await rybbit.init({
  analyticsHost: "https://app.rybbit.io/api",
  siteId: "YOUR_SITE_ID",
});

Stats API

Everything in the dashboard, over HTTP.

Every metric Rybbit shows is available from the REST API with a bearer key — pull traffic into your own tools, build a live feed, or export events to a warehouse. An API playground in the dashboard generates ready-to-use snippets.

API reference
terminal
curl "https://app.rybbit.io/api/sites/123/metric?parameter=country&start_date=2026-06-01&end_date=2026-06-30" \
  -H "Authorization: Bearer YOUR_API_KEY"
response.json
{
  "data": {
    "data": [
      { "value": "US", "count": 8420, "percentage": 54.63 },
      { "value": "GB", "count": 2150, "percentage": 13.95 }
    ],
    "totalCount": 87
  }
}

Organization keys or personal keys, rate-limited per plan. Sessions, metrics, funnels, goals, errors, and events are all endpoints — see the reference for the full surface.

MCP

Your agent already knows how to use it.

A hosted MCP server sits on top of the full REST API. Your agent reads live traffic, debugs errors, and manages goals — with the same permissions as a teammate.

Set up MCP
terminal
claude mcp add --transport http rybbit \
  https://app.rybbit.io/api/mcp
