Which tool

You have the idea. Now there are five tabs open and every one of them says it builds apps from a prompt. They are not interchangeable. Lovable makes it look designed. Bolt gets it running tonight. Replit hosts it and lets you edit the code. v0 stops at one screen. Emergent is the Indian one.

Open this one

Nobody comparing these is asking what they do. You have already decided to build something and you want permission to open one tab. Here is the permission.

Lovable
You want the thing to look right the first time, and it is mostly screens and a database.
Bolt
You want it running tonight and you will fix how it looks tomorrow.
Replit
You want to open the code the model wrote, change it, and host it in the same place.
v0
You already have an app and one screen in it is bad.
Emergent
You are paying in ₹, and you want support in your own working hours.

The table

Read the third column first. Every vendor on earth publishes what their tool is best at. Not one of them publishes the row that says where it stops.

Head to head

Six matchups, each settling one argument people are already having in comment sections. They arrive with a build made in each tool attached, which is the part a vendor blog cannot fake.

On prices

This page prints no prices. Every one of these five has changed its pricing at least once in the last year, and a page carrying a stale figure is worse than a page carrying none: it is checkable, it is wrong, and it is the fastest way to lose a ranking the page earned. Open the pricing page. It takes eleven seconds and it is correct.

What a first build costs in rupees is a different question, and it has its own answer: how much it costs to build an app with AI in India.

Where next

Pick one. Then stop reading about tools.

Comparing is the comfortable part and it does not produce a URL. Every build published here names the tool it used and the exact point that tool ran out, and each one is announced on Instagram first.
