What is Teardown?

A tool that takes any live website URL plus a plain-English question and returns a deep engineering architecture spec as a published HTML artifact — routes, frameworks, backend surface, data model, infra — built by AI agents.

Who is it for?

Engineers evaluating or onboarding onto unfamiliar codebases-by-example, tech scouts doing due diligence, consultants scoping rebuilds, and AI agents that need structured knowledge of how a production site is put together.

Is crawling other people's sites allowed?

Teardown performs authorized recon only: it fetches exactly the public surface a normal browser receives (HTML, JS, CSS). No credential guessing, no exploitation, no private data.

How much does it cost?

Credits at $0.01 each. A quick single-lens read costs ~5–15 credits; a full teardown of a mid-size site ~20–60 credits. Every account gets a free 100-credit bucket at signup. Details on the pricing page.

How long does a run take?

Usually a few minutes depending on site size. Progress is streamed per stage (recon → plan → dissect → synthesize → build) and runs are resumable.

Do I need to sign up?

You need an email magic link to run teardowns (no passwords), but estimates are free and require no account. New accounts include the free 100-credit bucket.

Can AI agents use Teardown programmatically?

Yes. The JSON API is documented at docs with an OpenAPI description at /openapi.json. This site also serves markdown twins of every page (/docs.md, /pricing.md, /faq.md, or Accept: text/markdown) plus /llms.txt for machine ingestion.

What do I get at the end?

A stable URL pointing at a self-contained, mobile-first HTML spec: executive summary, per-topic sections, and a "how to clone this" breakdown. It stays in your history forever.
