Getting clean data out of a webpage is still where a lot of agent pipelines break — you write a scraper, a site changes, and it quietly stops working. Tabstack, built at Mozilla, replaces that with an API: pass a URL and a schema, and get back JSON that matches every time, no scraper to maintain.

## What Tabstack does

Tabstack is browser-and-data infrastructure aimed at AI agents, with three endpoints doing the work. /extract turns a page into Markdown or structured JSON; /generate transforms content on the fly; and /automate lets an agent actually click, scroll, and fill out forms. The structured-extraction piece is the headline: instead of hand-built selectors, you describe the shape you want and Tabstack returns it. Pricing is usage-based — roughly $1 per 1,000 Markdown extractions, $5 for JSON — with a free tier of 50,000 credits a month, and the pages you extract aren’t used to train models.

## Why it matters

Agents are only as useful as the data they can reliably read and the actions they can take on the open web. A schema-in, JSON-out API that doesn’t break when a site’s HTML shifts removes one of the most fragile steps in building an agent — and coming from Mozilla, it lands with some credibility on the privacy side.
