Structured JSON extraction
Pass a URL and a JSON schema to receive output that matches the structure you asked for, such as product names, prices, sizes, or job listings.
Tabstack
Tabstack is a web data and browser automation API for extracting structured data, running live-web research, and completing browser tasks from a single call. It helps developers ship extraction, research, and automation features without building browser infrastructure or orchestration themselves.
Overview
Tabstack is a web data and browser automation API platform for extracting structured data, running live-web research, and completing browser tasks from a single call. It is positioned as a managed web API that removes the need to build and maintain your own LLM orchestration, browser infrastructure, or scraping pipeline.
The site presents three main workflows: extracting schema-matched JSON or Markdown from a URL, running a research agent that returns cited answers, and automating multi-step browser tasks on live pages. The common pattern is to provide a URL, a schema, a question, or a task, and receive a structured result back from Tabstack.
Features
Markdown extraction
Request clean Markdown from a page so articles, docs, and product pages can be reused in downstream workflows without maintaining a scraper.
Cited web research
Ask a question and get back a synthesized answer with inline citations and source URLs for each claim.
Browser automation
Describe a web task in plain language and Tabstack navigates, clicks, fills forms, and completes multi-step flows on live sites.
Streaming delivery
Results can stream over SSE for research flows, which lets users watch the answer come together instead of waiting for a single final response.
Developer access options
The site shows TypeScript SDK examples and also references Python SDK, MCP, and CLI support for using the APIs from agent or application code.
Use Cases
Structured data capture
Build a pipeline that turns a URL into structured records, such as product attributes, job listings, or competitor data, without writing your own scraper logic.
Customer-facing research assistant
Ship an in-product research feature that answers customer questions with sourced claims, citations, and source URLs instead of a plain summary.
End-to-end browser tasks
Automate bookings, checkouts, and other multi-step site workflows where a browser is required and no API is available.
Knowledge base ingestion
Convert articles, docs, and product pages into clean Markdown for knowledge bases or RAG systems that need readable source text.
Web operations tooling
Use one managed service for extraction and research jobs that otherwise would require separate crawling, parsing, orchestration, and browser automation layers.
