Moz Domain Authority 44/100 vs category average 35 / leader 99 - a strong backlink profile, so AI systems frequently encounter mentions of the brand.
esbuild appears on Wikipedia but without a dedicated company entity, so AI models can confuse it with similarly named subjects.
The homepage meta description reads "To provide web developers with an extremely fast JavaScript and CSS bundler that dramatically speeds up build times." (No meta description) - this is the summary AI engines are most likely to quote.
Structured data on the homepage: og:title, og:type. Adding Organization and FAQ schema would further help AI crawlers parse the brand's identity.
AI-crawler access: No robots.txt found (default: all bots allowed, but explicit file preferred) - robots.txt controls whether engines like GPTBot and ClaudeBot can read the site at all.
Social footprint: verified profiles on GitHub, Facebook, Instagram; no detected presence on X (Twitter), LinkedIn, YouTube - consistent profiles reinforce the brand's identity across the web.
0 Reddit mentions - community discussion signals real-world reputation to AI models.
esbuild scores 31/100 for AI visibility - how well ChatGPT, Claude, Perplexity and Google AI Overviews can discover, identify and cite the brand.
esbuild has a weak AI-visibility profile at 31/100 - a proxy for how readily ChatGPT, Perplexity and Google's AI Overviews can recognise and cite it. Its strongest area is recommendation likelihood (35/100) and its weakest is trust (26/100). It benefits from a Wikidata knowledge-graph entry, a Moz Domain Authority of 44/100 and open access for AI crawlers (GPTBot, ClaudeBot, etc.). The main gaps holding it back: no clear Wikipedia entity to anchor it in LLM training data, thin schema.org structured data and no llms.txt to steer AI to its best pages. In a live check, Claude could already identify esbuild from memory (August 2026) - a sign these signals are paying off.
Live results from asking a general-purpose AI assistant about the brand, checked August 2026.
When asked "What is Reason?", Claude could identify the brand as of August 2026. Reason is a syntax and toolchain for OCaml built by Facebook, letting developers write type-safe functional code that compiles to JavaScript via BuckleScript or to native code, often used with ReasonReact for building UIs. Best known for Bringing OCaml's type safety and functional programming style to JavaScript developers through a familiar syntax.
When asked "Best brands similar to Reason?", Claude would recommend esbuild as of August 2026. It's a notable option for developers wanting strong typing and functional programming in web development, especially those interested in alternatives to TypeScript or plain JavaScript.
