Tabstack - Web Data and Browser Automation APIs
Managed Web API
Extract data and automate the web in one API call
Pass a URL, a schema, a question, or a task. No LLM, browser, or pipeline to manage; it all runs on Tabstack. You get structured data, cited answers, or completed browser tasks in minutes. Never sold, never trained on.
✓10,000 free credits✓Never trained on✓No credit card required
/research
Run a research agent with cited answers in a single API call.
Ask a question and get back a synthesized answer with every claim cited to its source. Source selection, reading, synthesis, and citation all happen inside the call, so you ship a research agent your users can trust instead of building the backend that makes one work.
Features
- ✓Streams results over SSE
- ✓Inline citations on every claim
- ✓Answers from the live web, not a pre-indexed cache
/automate
Automate the web without running browser infrastructure.
Describe a task in plain language and Tabstack carries it out on the live page: navigating, clicking, filling forms, and completing multi-step flows on sites you don't control. The browser, the model, and the orchestration all run on Tabstack, so your stack or agent can act on the web without provisioning a browser or wiring in an LLM.
Features
- ✓Pauses for human input with interactive mode
- ✓Navigates, clicks, and fills forms on JS-heavy pages
- ✓Powered by Pilo, our open-source browser engine that uses 60-80% fewer tokens than screenshots
What people build
From endpoint to product.
Real products, built on a handful of calls instead of a data pipeline.
Competitive Intelligence Dashboards
Track competitor pricing, packaging, and positioning on a schedule. One call returns schema-matched JSON, so a live dashboard stays current without anyone copy-pasting from a browser.
/extract/json/generate/json
Lead Enrichment Pipelines
Turn a raw domain into headcount, tech stack, funding, and ICP fit. Enrich every inbound lead inside your pipeline instead of wiring up a stack of data vendors.
/extract/json/generate/json
Research Agents
Ship an in-product research feature that answers from the live web with a citation on every claim. Source selection, reading, and synthesis all run inside the call.
/research/extract/markdown
Booking & Checkout Agents
Complete real bookings and checkouts end to end. Describe the task in plain language and it navigates, fills forms, and finishes the flow on sites you don't control, with no browser to run.
/automate
Workflow Automation
Replace the brittle scripts behind back-office busywork. Fill and submit forms across third-party sites with no API, and pause for a human when a step needs judgment.
/automate
Knowledge Base Ingestion
Turn any page into clean Markdown your models can actually read. Feed docs, articles, and product pages into a RAG pipeline without writing or maintaining a scraper.

From the developers
“I signed in with Google and had a working API key right away. Then I made my first call and got back exactly what I asked for in minutes.”

The model, the browser, and the orchestration all run on Tabstack. You just make the call.
