A developer reverse-engineered the runtime environment of Anthropic's Claude Code web interface and discovered an unreleased, undocumented application hosting platform called 'Antspace' built on Firecracker microVMs. The investigation, conducted using standard Linux tools, reveals a potential AI-native PaaS competitor to platforms like Vercel, suggesting Anthropic's broader infrastructure ambitions beyond just AI models. The findings highlight the technical architecture choices (like Firecracker) common among new coding agent platforms.
Background
Anthropic is a leading AI company known for its Claude models, while Vercel is a popular platform for frontend deployment and serverless functions. Firecracker is an open-source virtualization technology from AWS, widely used for secure and fast microVM creation in serverless and container environments.
