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.
| Tool | Best at | Where it stops | Free tier | Based in |
|---|---|---|---|---|
| Lovable | A full app that already looks designed | Heavier backend logic outgrows it faster than the interface does | Daily message quota, resets | Sweden |
| Bolt | Getting to a running full-stack app in one sitting | Visual polish is yours to fix afterwards | Daily token allowance, resets | United States |
| Replit | Building and hosting in the same tab, then editing the real code | Prompt-to-app output needs more correction than Lovable's | Free workspaces, always-on hosting is paid | United States |
| v0 | One component or one screen, at a high standard | It is not trying to be a whole app, and it does not host one | Monthly credit pool | United States |
| Emergent | Agentic builds, with Indian support hours and Indian payment rails | Youngest of the five, so the smallest body of public failure reports | Trial credits, then paid | India |
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.
- Lovable vs BoltWhich one to open first, and what each is bad at.
- Replit vs LovableOne hosts and one designs. Which matters for your build.
- Bolt vs v0Full app against a component. Where each stops.
- Best AI app builder in IndiaPriced in ₹, tested on Indian cards and Indian connections.
- Free AI app buildersWhat the free tier actually gives you before it stops.
- Emergent AI reviewAn Indian builder at a $25M ARR run rate. Worth using or not.
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.
