 - **Native Browser Primitives**: When full single-page application (SPA) rendering or visual screenshotting is required, Antigravity delegates directly to Antigravity's native browser subsystem—completely eliminating the need to maintain a headless browser daemon in the CLI engine.
 
 #### 3. Native Search Grounding vs. Third-Party Paid MCP Sprawl
-- **Zero-Config Google Grounding**: Traditional agent SEO toolsets require users to sign up, configure, and pay for third-party search APIs (Brave Search, Serper, Firecrawl, or DataForSEO) just to inspect competitive SERPs and People Also Ask (PAA) queries.
-- **Built-in Grounding**: Antigravity provides native `search_web` (direct live Google search results) and `read_url_content` (high-speed markdown conversion without browser overhead). You get real-time SERP rankings, intent clustering, and competitor page analysis right out of the box with zero subscription keys.
+- **Zero-Config Google Grounding**: While `claude-seo` relies on optional paid third-party MCP extensions (DataForSEO, Firecrawl, Ahrefs, SE Ranking, Profound) for live Google SERP positions, large-scale site crawling, and backlink graphs, Antigravity SEO provides native `search_web` (live Google search grounding) and `read_url_content` (high-speed markdown conversion without browser overhead) right out of the box with zero external subscriptions.
 
 #### 4. Native Google Search Console (JWT RSA) & Public Backlinks
 - **Enterprise GSC Integration**: `seo-engine` includes a zero-dependency Google Service Account client (`internal/api/gsc.go`). It mints RS256/PKCS8 JWTs and exchanges them for OAuth2 bearer tokens directly, unlocking Search Analytics (`seo-engine gsc query`) and URL Inspection (`seo-engine gsc inspect`) without client secrets or web redirects.
