Compare Gaffa vs. Verid

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.

Verid is an API designed for developers that focuses on monitoring webpage changes through structured data rather than relying on screenshots. It alerts users only when specific fields of interest change, such as price or stock status, by triggering a webhook based on customizable conditions. This approach emphasizes state monitoring over visual comparisons, offering features like structured data extraction, persistent state tracking, field-specific differences, and condition-based notifications all within a single workflow. Each monitoring instance operates according to a schedule defined via a comprehensive REST API that conforms to the OpenAPI 3.1 specification, allowing teams to manage configurations while Verid handles the backend infrastructure. The process comprises five distinct stages: fetching, extracting, differentiating, assessing predicates, and delivering results. Verid initially employs a static fetch method but can seamlessly switch to a headless browser when necessary, and if challenges arise, it can further adapt by using a residential proxy for enhanced access. This flexibility ensures that users can effectively monitor any webpage regardless of its complexity.
