gv web viewer

gv web viewer is a sandboxed page renderer designed for SEO analysts, QA engineers, and web developers. It loads a given URL in a contained environment and returns structured render data that aids auditing and debugging.
Conceptually, rendering involves fetching the page, executing allowed scripts, and recording the DOM state, resource timing, and metadata without exposing the browser UI. Results include an HTML snapshot, a DOM model, and performance signals such as render_time_ms. This helps identify render-blocking resources, missing meta tags, and layout shifts across domains.
Unique value lies in its safe sandbox, deterministic inputs, and exportable data formats that fit into audit workflows. Core features include configurable viewport, timeout, script handling, HTML snapshot, screenshots, and a structured DOM representation. Use cases cover SEO audits, accessibility checks, QA verification, and performance benchmarking for agencies and product teams.
The tool focuses on domain logic rather than UI; it is designed for automated pipelines and AI agents to consume render data, compare pages, and generate reports.
