GrackerAI, the AEO and GEO platform built for B2B SaaS and cybersecurity companies, announced that its VS Code extension is live on the Visual Studio Marketplace. The free extension validates llms.txt, robots.txt, and AI visibility signals directly inside the editor, allowing developers to catch technical issues that can strip a website of citations in ChatGPT, Claude, Perplexity, and Google AI before code reaches production. "AI engines decide which brands to cite based on what they can crawl and read, and most teams discover a problem only after the citations are already gone," said Deepak Gupta, Co-founder and CEO of GrackerAI. "We moved that check left, into the editor, where developers can fix it in seconds instead of debugging it in a dashboard weeks later." The launch reflects a broader shift GrackerAI has tracked since its founding, as AI engines serve answers and cite sources rather than traditional blue links. "Every developer can now see AI visibility issues the moment they write the code," added Govind Kumar, Co-founder and CPO of GrackerAI. The VS Code extension is available now, free, on the Visual Studio Marketplace. GrackerAI was founded in 2025 in San Francisco.
