Platform Overviews
Bolt
Bolt is an AI-powered website and application builder developed by StackBlitz, primarily used by developers and technical users who want to rapidly prototype and deploy full-stack web applications directly from natural language prompts. The platform generates production-ready code in the browser, making it a distinctive target for detection due to its tight integration with StackBlitz's runtime infrastructure. AIWebsiteDetector's detection engine identifies Bolt-built sites through a combination of 3 script patterns, 3 HTML patterns, and 2 meta tag patterns embedded in the page markup, alongside 2 CDN domains that consistently appear in asset delivery and 2 HTTP response headers that expose the underlying platform. These signals work in combination to produce reliable detections across a range of project types, from single-page applications to more complex full-stack deployments. Bolt sites are characteristically hosted within the bolt.new ecosystem or exported to connected deployment targets, and the platform's deep reliance on WebContainer technology leaves consistent, identifiable fingerprints across both the DOM structure and network layer that distinguish it cleanly from other AI website builders.
Gamma
Gamma is an AI-powered presentation and website builder aimed at professionals, educators, and teams who need to create polished decks, documents, and landing pages without traditional design overhead. Sites built with Gamma are hosted on Gamma's own infrastructure under the gamma.app domain, making the hosting environment itself a reliable primary signal for detection. AIWebsiteDetector.com's detection engine identifies Gamma-built sites using a combination of 3 script patterns, 3 CDN domains, 3 HTML patterns, 2 HTTP headers, and 2 meta tag patterns — giving the engine multiple redundant signals to confirm attribution with high confidence even when pages are customized or embedded. The HTML patterns typically surface in structural attributes and class conventions injected by Gamma's rendering pipeline, while the script patterns reflect the platform's bundled JavaScript assets loaded consistently across published sites. The reliance on Gamma's own CDN infrastructure and proprietary HTTP response headers makes this one of the more straightforward builder fingerprints in the detection database, with little ambiguity between Gamma and other AI site builders. Gamma operates on a freemium model with paid plans for advanced features, and because virtually all published Gamma sites resolve through gamma.app subdomains or custom domains with consistent header signatures, detection accuracy remains exceptionally high across site types.
Key Differences
- Both Bolt and Gamma are classified as AI Website Builder tools, making them the most direct competitors in this comparison.
- Bolt scores higher on AI involvement (90/100 vs 90/100 for Gamma), meaning it relies more heavily on AI for site generation and content creation.
- Our detection engine identifies Bolt using 12 fingerprint patterns and Gamma using 13 patterns — more signals generally means more reliable detection.
- Bolt serves assets from
/bolt\.host/iwhile Gamma uses/assets\.gamma\.app/i— making CDN domain analysis one of the most reliable ways to distinguish them.
Which Should You Choose?
