Time to clone — the amount of time it takes for someone to copy exactly what you have — is shorter than ever before.

AI coding tools like Cursor and Windsurf currently lack defensibility because there is neither data lock-in nor social lock-in — a user can switch with nothing lost

Lock-in comes either from accumulated data that makes the tool better or from collaboration that makes switching painful, and neither applies yet to these tools

Scope: as of today; may change

Vibe coding is widely considered a business with no moats, evidenced by how easily major founders have spun up their own Base44 equivalents in three months

Founders of Salesforce, Atlassian, Cloudflare, Figma and Nothing have each built their own equivalent products quickly

Scope: presented as the criticism others make of the category

Building a vibe coding tool is easy, but building a platform that produces functional, complex, real-world software is very hard — and that difficulty is the category's moat
