ENGIN REV 1.0 PRE-LAUNCH —
WAITLIST — OPENING SOON

Describe your app in plain English.
Get real code, every single time.

ENGIN turns a conversation into a working web app, mobile app, backend, and database — built from a precise spec, not an AI's best guess. No broken re-prompts. No random regressions.

WHY IT'S DIFFERENT
01

Doesn't randomly break

The same spec produces the same code every time. Ask for one small change and the rest of your app stays exactly as it was.

02

Costs less to run

The AI writes a short spec, not full code files, on every request — so it uses a fraction of the compute the "AI writes your code" tools burn.

03

Real code, not a black box

What comes out is a normal Next.js, React Native, Node, and Postgres codebase — handoff-ready for any engineer, anytime.

Vibe coding vs. ENGIN

Vibe coding (Bolt, v0, Lovable)
ENGIN
AI writes the actual code directly from your prompt, every time.
AI only ever writes a structured spec — the Blueprint. It never touches code.
No permanent record of the app's structure — only chat history and whatever code exists now.
The Blueprint is a permanent, precise document. Nothing gets forgotten between changes.
Same prompt can produce different code. Small edits can touch unrelated parts.
A separate, non-AI compiler builds from the spec. Same input, same output, always.
Gets less reliable as the app grows — more for the AI to "remember" each time.
Reliability doesn't degrade with size — the compiler follows rules, it doesn't improvise.
Regenerates large chunks of code per prompt — expensive, thin margins.
Only ever generates a small spec patch — dramatically cheaper per change.

Capabilities

Self-healing

When something breaks, ENGIN traces the error back to the exact spot in the spec, proposes a fix, and re-checks it — automatically, with a limit so it never loops forever.

Quality gates

Every app is checked before it ships: no broken links, no unprotected pages, no unsecured data. Nothing compiles until it passes.

Live preview

Watch your actual app take shape in real time as you talk — not a mockup, the real thing running live.

Two modes

A simple, visual mode if you're non-technical. A full code + diff view if you're an engineer. Same app, either lens.
