Ship fast, iterate effortlessly

Not a mockup generator. Cogsynth builds the whole app, then verifies it, syntax, broken assets, missing content, and runtime errors are caught before you ever see the preview.

Builds on Any Device

Designed to work on your phone as well as your desktop. No local setup, no terminal.

Verifies Its Own Work

Every build is checked for undefined references, broken images, empty pages, and runtime errors, then repaired before you look at it.

Guided Suggestions

Don't know what to type next? Contextual suggestions move you from idea to finished app.

One-Prompt Workflow

Describe everything at once. No wizards, no 20-step forms, including long PRDs.

120+ Production Templates

SaaS, stores, dashboards, blockchain dApps, portfolios, start polished, customize fast.

Drop-In Modules

Auth, Postgres, Stripe checkout, and more, wired into the app instead of stubbed out.

"That was much easier than I thought it would be." - Tyler · "It was really cool to use, and it looked surprisingly good on mobile." - Carol · "I love how it wires in custom templates to speed up app creation. It's like a genie." - Bill · "I was able to turn a 20 page PRD into a working MVP in a single prompt." - Daniel · "This works so much better than the other builders I have tried out." - Andy ·

How It Works

Three steps. No coding required.

1

Describe

Brain-dump your idea in one prompt. Use as much or as little detail as you want.

2

Iterate

Watch the app come to life right in the Cogsynth dashboard. Click suggestion chips to iterate. Cogsynth's suggestions are tailored to your project, so you can just approve what you like, and watch it build.

3

Ship

Export clean code as a ZIP, publish to a live share link, or keep building out your project.

What it does

Not a chat wrapper. A purpose-built system for turning intent into working software.

Custom multi-agent harness

A native tool-calling loop built for code, not a generic chatbot. The agent plans, writes, verifies its own output, and repairs what it breaks.

Suggestion engine

Contextual next steps drawn from your actual project, so you are never staring at an empty prompt box.

Template library

120+ production scaffolds across SaaS, commerce, events, games, and Web3. A starting point, not a cage.

Drop-in modules

Auth, payments, database, and pipelines wired into the app automatically. Cogsynth builds with these additions in mind.

Project planner and annotator

Your request becomes an explicit build plan and PRD you can read and edit, so you always have full control over the direction.

Passive researcher

Canvas reads docs and notes and searches for complementary sources while it writes, so new code fits what is already there.

Precise documentation

Generated apps come with real docs describing structure and behaviour, not a README placeholder. Cogsynth references and maintains them to reduce scope drift.

Autopilot

Self-improving suggestions that keep proposing the next step, so a project can grow without you driving every turn.

Flagship and open source

Works with frontier hosted models or fully open-weight ones. Bring your own keys, or start from a repo you already own.
