GitHub Copilot

GitHub Copilot is an AI-powered code completion and assistance tool developed by GitHub and OpenAI, primarily used by software developers and engineering teams to accelerate coding workflows directly within editors like Visual Studio Code. On the web, GitHub Copilot's presence is typically identified through its integration within GitHub's own infrastructure, and AIWebsiteDetector's detection engine relies on 2 distinct HTML patterns to confirm its deployment on a given page. These patterns include specific markup signatures embedded within GitHub's feature pages and product surfaces, allowing the detector to distinguish Copilot-related content from other GitHub properties with reasonable precision. Because Copilot is a first-party GitHub product rather than a third-party embed, it does not distribute external CDN scripts or inject independent tracking headers — its detection footprint is tightly coupled to GitHub's own domain and HTML structure at its official home, github.com/features/copilot. This native integration makes GitHub Copilot a relatively contained detection target, where confidence depends almost entirely on structural HTML fingerprinting rather than network-level signals like script sources or HTTP headers.

Astro

Astro is a modern static site generator and web framework designed for content-focused websites, widely adopted by developers building blogs, documentation platforms, marketing sites, and portfolios who prioritize performance through minimal JavaScript delivery. AIWebsiteDetector.com identifies Astro-powered sites using a combination of 2 distinct script patterns, 3 HTML patterns, and 1 HTTP header signal — a precise fingerprint that reflects how Astro renders its component island architecture into the DOM. The HTML patterns typically surface in the markup structure and custom attributes Astro injects during its build process, while the script patterns correspond to Astro's client-side hydration modules that accompany interactive components on the page. The HTTP header signal further corroborates detection, often appearing in server or CDN response metadata associated with Astro's deployment targets such as Netlify, Vercel, and Cloudflare Pages. Astro is open-source and free to use, with hosting costs determined entirely by the chosen deployment platform, making it a common choice across a wide spectrum of project scales — from personal sites to enterprise documentation. This multi-signal detection approach gives AIWebsiteDetector.com high confidence when classifying Astro sites, as the combination of build-output HTML markers and runtime script patterns is difficult to mask without fundamentally altering Astro's default output behavior.

Key Differences

Both GitHub Copilot and Astro are classified as AI Coding Tool tools, making them the most direct competitors in this comparison.
GitHub Copilot scores higher on AI involvement (65/100 vs 65/100 for Astro), meaning it relies more heavily on AI for site generation and content creation.
Our detection engine identifies GitHub Copilot using 2 fingerprint patterns and Astro using 6 patterns — more signals generally means more reliable detection.
