Tabstack is a managed web API that helps developers extract data, generate structured outputs, run live-web research, and automate browser tasks through simple API calls. The platform lets users pass a URL, schema, question, or task and receive schema-matched JSON, clean Markdown, cited answers, or completed browser actions without managing an LLM, browser, scraper, or orchestration pipeline. Its endpoints support structured extraction, Markdown extraction, JSON generation, live research with citations, and web automation across JavaScript-heavy pages. Developers can use Tabstack for competitive intelligence dashboards, lead enrichment, research agents, booking and checkout agents, workflow automation, and knowledge base ingestion. The platform includes SDKs for TypeScript and Python, MCP support, CLI tools, streaming research results, human-in-the-loop automation, and privacy-focused data handling.
