Tabstack

Overview Tabstack is a managed web API that extracts structured data, runs web research, and automates browser tasks in a single API call. Developers pass a URL, schema, question, or task and receive structured JSON, cited answers, or completed browser actions — without managing LLM orchestration, browser infrastructure, or extraction pipelines. Unlike building custom scrapers or wiring together LLM agents with browser automation tools, Tabstack handles the browser, the model, and the orchestration on its own platform. It is Mozilla-backed, private by default, and never trains on user data. Key Benefits Returns schema-matched JSON inside a single API call without maintaining extraction pipelines. Automates browser tasks — navigating, clicking, filling forms on JS-heavy pages — without provisioning browser infrastructure. Runs research agents that synthesize answers from the live web with inline citations on every claim. Powered by Pilo, an open-source browser engine that uses 60-80% fewer tokens than screenshot-based approaches. All requests and retrieved pages are purged after use and never sold or used to train models. New accounts start with 10,000 free credits with no credit card required. How It Works You sign up, get an API key, and call one of five endpoints — /extract/json, /extract/markdown, /generate/json, /research, or /automate. You pass a URL plus a schema, question, or task description in plain language, and Tabstack handles the reasoning, rendering, browser execution, and schema enforcement inside the call. Results return as structured JSON, clean Markdown, a synthesized report with citations, or a completed browser task. Use Cases Competitive intelligence analysts — track competitor pricing, packaging, and positioning on a schedule with schema-matched JSON returned in one call. Lead enrichment engineers — turn a raw domain into headcount, tech stack, funding, and ICP fit data without wiring up multiple data vendors. Product developers building in-product research features — ship a research agent that answers from the live web with a citation on every claim. Booking and checkout automation teams — complete real bookings and checkouts end to end by describing the task in plain language. Back-office automation engineers — replace brittle scripts behind form filling and submission across third-party sites with no API, pausing for human judgment when needed. RAG pipeline builders — convert any page into clean Markdown for feeding docs, articles, and product pages into a knowledge base without maintaining a scraper. Why Choose This Product Tabstack suits developers and teams who want to extract data, run research, or automate browser tasks without managing browser infrastructure, LLM orchestration, or extraction pipelines. It is best for those who value privacy — the platform is Mozilla-backed, never trains on user data, and purges requests after use. No explicit limitations are mentioned in the provided content.
