# Tabstack

> Web browsing infrastructure for AI systems. Tabstack gives agents finished output from every web interaction: structured data, cited research answers, and completed browser tasks, each from a single API call. Backed by Mozilla. Nothing you send is sold or used to train models.

## Products

- [Structured Data Extraction](https://tabstack.ai/structured-extraction): Define a schema, pass a URL, and get back JSON that matches. No parsing code, no downstream LLM call, no extraction layer to maintain. Endpoints: /extract and /generate.
- [Autonomous Research](https://tabstack.ai/web-research): Run a research agent with cited answers in a single API call. Live-web sourcing, multi-source synthesis, and SSE streaming, without building or maintaining a research pipeline. Endpoint: /research.
- [Browser Automation](https://tabstack.ai/browser-automation): Automate the web without running browser infrastructure. Navigation, clicks, forms, and multi-step flows on JS-heavy pages, in one API call. Endpoint: /automate.
