ReasonateAI is an AI website and app builder: tell it what you want in plain words, no coding needed. It plans the app, writes the code, tests it and fixes what breaks, while you watch a live preview. Happy with it? Download it or put it online.

LinkedInTry it first. Then go live.
Every app gets two copies: a private test copy and the live one. Changes run in the test copy first. Only what passes goes live, so your users never see a broken build.
Test twin
A fresh, private copy of your app for every change. It gets run, tested and checked here, so nothing touches your live site.
A fresh private copy for every change. Tested here, so your live site stays safe.
Live twin
The version your users see. It only gets changes that already passed. If something goes wrong while it runs, it gets spotted and fixed.
What your users see. It only gets tested changes, and problems get fixed fast.

Test it in a sandbox
Your app runs in its own sealed-off container (React + Vite, FastAPI, Node or Vue) with its own preview link. You see it working before anyone else does.

How it works
Idea to live app in three steps
You describe it. The AI does the heavy lifting.
Describe your idea
Type what you want to build, in plain words, and attach any files that help. The AI works out the pages, the data and the setup for you.
AI builds and tests it
It writes the code and runs it in a private sandbox. Tests run on their own, and the AI fixes what breaks. You watch it all in a live preview.
Go live
Share the live preview link, download the code, or keep changing it by chatting. Every build is checked in a sandbox and its errors fixed before you see it.
STEP 01

Plain words, any language
STEP 02

It writes the code and runs it in a private sandbox. Tests run on their own, and the AI fixes what breaks. You watch it all in a live preview.
Private preview, nothing public yet
STEP 03
Go live
Share the live preview link, download the code, or keep changing it by chatting. Every build is checked in a sandbox and its errors fixed before you see it.
Share, download or keep editing
What you get
Everything you need to ship
From the first prompt to a live app, without writing a single config file.
Just chat
Build by chatting
Say what you want in plain words. No scripts, no setup files.
Safe preview
Test before it goes live
Every change runs in a private copy of your app first, never on your live site.
Auto testing
Tests run for you
Your code, services and settings get checked automatically before anything ships.
You stay in control
Approve what ships
Changes pass clear checks and approvals before they go out, and every step is logged.
Auto-fix
Fixes its own mistakes
When something fails, the AI finds the cause and fixes it for you.
Always on
Built for zero downtime
Updates roll out step by step and get checked along the way, so your app stays up.
Say what you want in plain words. No scripts, no setup files.
Coming in 2027
Your virtual CTO
Building is step one. Next, ReasonateAI will look after security, cloud costs and server setup too.
Security checks
Checks access rules, scans for leaked passwords and keys, and patches weak spots before you go live.
Lower cloud bills
Tracks what your servers use, shuts down idle ones and keeps spending inside your budget.
Server setup, done for you
Writes and updates your Docker, Kubernetes and Terraform files, so you never have to touch YAML.
Checks access rules, scans for leaked passwords and keys, and patches weak spots before you go live.
Built for people with ideas.
Founder, developer, freelancer or student: if you can describe it, you can build it.
Launch your product without hiring a tech team.
Go from idea to a working app, fast. ReasonateAI plans it, builds it and tests it, so you can focus on your customers.

No. Describe what you want in plain words and ReasonateAI writes the code. If you do code, you can read and edit everything it makes.
Websites, landing pages and web apps: portfolios, business and restaurant sites, dashboards, event and product pages. Pick HTML, React, Next.js, Vue, Svelte, Angular or Preact, or let it choose. It can also write backend API code in Express, FastAPI or Flask.
Yes. Everything generated for you is yours. Paid plans include viewing and downloading the full project; on the Free plan, downloading the code of a version takes 1,000 credits, and ₹7 adds 2,500 credits.
Yes. The Free plan needs no credit card and its starter credits build one complete app, which you can keep editing and preview. Downloading its code takes 1,000 credits (₹7 adds 2,500). Upgrade for monthly credits, code downloads included and priority support.
Yes. Keep chatting, for example "make the header blue" or "add a pricing section", and watch the change in the live preview.
A template gives you a fixed design to fill in. ReasonateAI builds around your idea, and you can change anything just by asking.
Yes. Describe your business, for example "a site for my bakery in Pune with a menu, prices and a contact form", and ReasonateAI builds it with your sections, text and colours. You can then change anything by chatting.
You can build one complete app free with no credit card. The Pro plan is ₹200 a month in India (16,300 credits, 20+ app builds) or $5 a month internationally (38,800 credits, 45+ builds), and the team plan is ₹700 or $22 a month. Indian prices include GST.
Each build runs in its own isolated sandbox, your data is encrypted, and we never sell it. Our Privacy Policy and Security page have the details.
