Compare Gaffa vs. Tabstack

Gaffa is a REST API built for web scraping and browser automation, allowing developers to run real, full browsers at scale with a single API call. It removes the difficulty of managing headless browser frameworks, rotating proxies, CAPTCHA solving, and scaling infrastructure, all of which are handled automatically. JavaScript-heavy and dynamic websites render exactly as they would for a human visitor by default. Beyond standard scraping, Gaffa supports AI-driven structured data extraction (extract data into a defined schema without writing CSS selectors), screenshot and PDF capture, infinite-scroll and form-filling automation, and clean Markdown conversion for feeding webpages directly into LLM and RAG pipelines. A rotating residential proxy network keeps access reliable across regions, and a credit-based pricing model means teams pay only for the browser time and bandwidth they actually use. Gaffa is designed for AI engineers, data teams, and developers who want production-grade web data extraction without having to build and maintain their own infrastructure.

Tabstack is a managed web extraction, research, and automation API designed to help developers build live-web features without maintaining browser infrastructure or scraping pipelines. Users can send a URL, structured schema, research question, or plain-language task and receive clean data, cited research, or completed web actions from a single API call. The platform includes endpoints for extracting schema-matched JSON, converting pages into clean Markdown, generating structured outputs, running cited research agents, and automating browser tasks. Tabstack handles the reasoning, rendering, schema enforcement, browser execution, and orchestration behind the scenes so teams can focus on building products instead of managing extraction systems. Its research endpoint reads the live web, selects sources, synthesizes answers, and returns citations on claims, making it useful for trustworthy research agents. Its automation endpoint can navigate, click, fill forms, and complete multi-step workflows on third-party sites, with interactive pauses when human input is needed. Tabstack also supports TypeScript and Python SDKs, MCP integration, CLI access, and streaming responses over SSE. Developers can use it for lead enrichment, competitive monitoring, knowledge base ingestion, workflow automation, booking flows, product data extraction, and in-app research. With privacy controls, no model training on user data, and plans ranging from free credits to enterprise quotas, Tabstack gives teams a practical backend for AI agents that need to understand and act on the web.
