Leaked screenshots reveal Anthropic's secret full-stack app builder inside Claude chatbot

Leaked screenshots reveal Anthropic's secret full-stack app builder

Screenshots leaked on X show Anthropic testing a full-stack app builder within its Claude chatbot. The interface promotes the tagline "Let's ship something great" and enables users to generate applications from simple text prompts, including AI chatbots and games. The new feature reportedly includes live previews, integrated databases, and authentication tools, alongside a one-click deployment button. This app builder is distinct from Claude Code, Anthropic's existing command-line coding assistant, and caters to no-code users looking to create software through conversational prompts. If confirmed, this tool would directly compete with Lovable, a leading player in the vibe-coding sector. Lovable raised $330 million in a Series B funding round in December 2025, achieving a valuation of $6.6 billion. The round was led by Alphabet's CapitalG and Menlo Ventures. Lovable reported $200 million in annual recurring revenue by November 2025, with over 100,000 new projects created daily on its platform. Lovable's head of growth, Elena Verna, expressed concerns regarding competition from larger AI companies, stating that they present a greater threat than smaller rivals. This leak follows a recent setback for Anthropic, which inadvertently leaked 512,000 lines of Claude Code source code in March 2023, revealing numerous unreleased features and prompting the company to issue over 8,000 copyright takedown notices. KeyBanc analyst Jackson Ader noted that Anthropic's move into vertical tools implies a broader platform strategy, potentially expanding into various industries, including legal, sales, marketing, and finance.

Anthropic May Be About to Drop a Vibe-Coding Feature. It Could Change Everything

A new feature may be coming to Claude, and it could be an existential threat to the fast-growing vibe-coding market. On April 12, X user @hysteresis_x posted a screenshot of what they claimed was a new feature coming to Claude. The screenshot depicted a typical chatbot interface, plus an animated version of Anthropic's mascot Claw'd, under a message that read "let's ship something great." Other leaked images depicted an analytics dashboard and a game that users can play while their app is being created (similar to Google Chrome's Dinosaur game). The X user said the screenshots came from a "lovable-like feature where you can build full-stack apps easily." Lovable is one of Europe's greatest AI success stories; the company sells access to a platform that enables anyone, at any skill level, to build websites and applications, a practice commonly called vibe coding. Lovable and fellow vibe-coding companies Replit and Bolt have exploded in popularity over the last year, largely by using Anthropic's Claude models to power their platforms. Software engineers have adopted Anthropic's own Claude Code product en masse, but it still hasn't fully broken through among non-coders. Up until now, these vibe coding companies have had a friendly, mutually beneficial relationship with Anthropic. Should this feature be released, though, Anthropic's relationships with these platforms could significantly change.
