# Totallytics > Website analytics at https://totallytics.com. Register a site, install the tracking script, and query statistics. Private reports, site management, and historical imports require a signed-in user's Firebase ID token. Public-site metadata/statistics and collection do not. There are no static Totallytics API keys. Import history only when requested, following the import and migration guides. Collector HTTP 200 does not prove persistence. Read the setup guide before changing a site. ## Documentation - [Quickstart](https://totallytics.com/docs/quickstart.md): Register your website, add one script, and verify your first pageview. - [Installation](https://totallytics.com/docs/installation.md): HTML, React, Next.js, single-page apps, script settings, and CSP. - [Custom events](https://totallytics.com/docs/events.md): Track the actions that matter, in the browser or on your server. - [Authentication](https://totallytics.com/docs/authentication.md): Get an account token and understand which requests need one. - [Sites](https://totallytics.com/docs/sites.md): Register, list, update, and remove your websites. - [Statistics](https://totallytics.com/docs/stats.md): Query overviews, time series, live visitors, and breakdowns. - [Historical imports](https://totallytics.com/docs/imports.md): Discover sources, start background imports, and inspect their progress. - [Collector](https://totallytics.com/docs/collector.md): Send pageviews, events, and engagement data over HTTP. - [AI agent setup](https://totallytics.com/docs/agents.md): Give your coding agent a complete, verifiable setup plan. - [Migrate from Simple Analytics](https://totallytics.com/docs/migrate-simple-analytics.md): Switch your tracking script and plan your historical data import. - [Troubleshooting](https://totallytics.com/docs/troubleshooting.md): Find missing pageviews, fix authentication, and interpret errors. ## Machine-readable reference - [Complete documentation](https://totallytics.com/llms-full.txt) - [OpenAPI 3.1](https://totallytics.com/openapi.json)
