Lovable vs Bolt vs Greta: Which AI App Builder Should You Actually Use?

You want to build an app fast using AI. You found three tools: Lovable, Bolt, and Greta.

They all do the same thing but differently. Which should you pick?

This guide compares them head-to-head so you can decide.

The Quick Answer

Speed matters most: Bolt

Design matters most: Lovable

Production matters most: Greta

Still not sure: Bolt (it's free and fast)

The Comparison

Speed

Bolt: 1-2 hours

Lovable: 4-8 hours

Greta: 3-5 days

Bolt wins. It's the fastest.

If you want something working in the next 2 hours, use Bolt.

Code Quality

Bolt: Fair (works but sometimes messy)

Lovable: Good (clean, well-structured)

Greta: Excellent (production-ready, audited)

Greta wins. The code is actually production-ready.

Design Quality

Bolt: Basic (functional but plain)

Lovable: Beautiful (looks professional)

Greta: Good (functional and nice)

Lovable wins. Your app will look great.

Security

Bolt: Adequate (standard security)

Lovable: Good (standard security)

Greta: Excellent (audited for security)

Greta wins. They audit for vulnerabilities.

Learning Curve

Bolt: Easiest

Lovable: Easy

Greta: Medium (takes a little longer)

Bolt is easiest to get started with.

Cost

Bolt: Free

Lovable: Free to $99/month

Greta: Free to $300/month

Bolt is free. Lovable and Greta are cheaper initially but cost more for production.

Three Real Scenarios

Scenario 1: You have an idea and want to test it THIS WEEK

You don't have time to wait. You want to show something to potential users in 2 days.

Use Bolt.

Reasons:

• —Fastest (1-2 hours)
• —Free
• —Gets something working NOW
• —Good enough to test with users
• —If it's trash, you didn't waste money

Build with Bolt in 2 hours. Show to 10 people. Get feedback. Decide if it's worth building properly.

If yes: Build a better version with Lovable or Greta.

If no: You lost 2 hours, not 2 weeks.

Scenario 2: You're building something you want to be proud of

You're launching a side project. You want it to look good. You want to show investors or users something polished.

Use Lovable.

Reasons:

• —Beautiful design (not basic)
• —Still reasonably fast (4-8 hours)
• —Good code quality
• —Investors will be impressed
• —Users will enjoy using it
• —Cost is reasonable ($20-50)

You'll have something that looks professional. Not cookie-cutter.

Scenario 3: You're starting a business

You've validated the idea. People want it. You need to build something production-ready that will actually make money.

Use Greta.

Reasons:

• —Production-ready code (not prototype code)
• —Secure (audited for vulnerabilities)
• —Scales (can handle growth)
• —Clean code (easier to hire developers later)
• —Support (they help with issues)
• —Long-term reliability

Yes, it costs more. Yes, it takes longer. But you're building something real.

The Features Comparison

| Feature | Bolt | Lovable | Greta | |---------|------|---------|-------| | Speed | 1-2h | 4-8h | 3-5d | | Code quality | Fair | Good | Excellent | | Design | Basic | Beautiful | Good | | Security | Good | Good | Excellent | | Support | Community | Email | Direct | | Ideal for | MVP | Side projects | Businesses | | Cost | Free | Free-$99 | Free-$300 |

How They Actually Work

All three use the same basic process:

1. You describe your idea

"An app where remote teams share daily updates"

2. AI builds it

The tool generates the app.

3. You refine it

"Make the button blue" "Add timestamps"

4. It updates automatically

The AI changes things.

5. You ship it

Deploy to the internet.

The difference is HOW WELL the AI understands you in step 2 and 4.

All three are pretty good. All three will build something that works.

The Real Differences

Bolt philosophy: Fast and free. Good enough. Let users test it.

Lovable philosophy: Beautiful. Professional. People enjoy using it.

Greta philosophy: Production-ready. Secure. Built to last.

Real Workflow Example

Step 1: Use Bolt to validate

Idea: "An app where Airbnb guests rate their hosts"

Build with Bolt: 2 hours

Show to 20 Airbnb users: Get feedback

"Yeah, this is useful" vs "Nah, don't care"

If nah: You spent 2 hours and $0. You learned.

If yeah: Build v2.

Step 2: Use Lovable to build v1 for real

Now you know people want it. Build something nice.

Use Lovable: 6 hours

Show to more users: "Would you pay for this?"

Get feedback on pricing, features, design.

Step 3: Use Greta for production

People love it. You want to turn it into a real business.

Use Greta: 2 weeks

Now you have production-ready code. You can:

• —Run a business on it
• —Hire developers to extend it
• —Scale to 10,000 users
• —Add payment processing

Can You Switch Between Them?

Yes. You can:

• —Start with Bolt
• —Export the code
• —Import to Lovable
• —They'll improve it
• —Export again
• —Use Greta to make it production-ready

The tools aren't locked-in. Your code is yours.

Which One Should You Actually Start With?

If you have any doubt: Bolt.

It's free. It's fast. Worst case, you lose 2 hours.

Best case, you have something working you can show people.

If you have money: Lovable.

Better design. Better code. Still fast.

If you're serious about business: Greta.

Production-ready from the start. Audited security. Peace of mind.

The Honest Comparison

Bolt: Good for students, experimentation, MVPs, learning.

Lovable: Good for side projects, portfolios, startup launches, design-focused apps.

Greta: Good for real businesses, security-conscious projects, long-term products.

None are "better." They're better for different things.

Common Questions Answered

Can these replace developers?

Not forever. They replace developers for MVPs. For growing businesses, you'll hire developers. But you'll start with less code to maintain. That's a win.

Is the code actually good enough for production?

Bolt: No. Lovable: Mostly. Greta: Yes.

Can I hire a real developer to improve what I build?

Yes. You have the code. A developer can take it from there.

What if I need custom features?

All three can handle most features. For extremely custom stuff, hire a developer.

How long does each take to learn?

Bolt: 5 minutes. Lovable: 15 minutes. Greta: 30 minutes. None need learning.

Which one is cheapest?

Bolt. It's free. But Lovable free tier is good too.

Which one gives the best results?

Lovable for design. Greta for code. Bolt for speed.

Can non-technical people use these?

Yes. All three are designed for non-technical people.

What's the failure rate?

Most people who start finish. The question is quality of result. Bolt results are basic. Lovable results are good. Greta results are great.

Can I build a business on these?

Yes. Many people have. Bolt for MVP validation. Lovable or Greta for actual business.

Should I use all three?

Some people do. Start with Bolt. If it's worth building, move to Lovable. If scaling, move to Greta.

What if I'm already a developer?

You probably want to use Cursor (AI-powered code editor) instead. These are for non-developers.

Can I use these for large projects?

Greta: Yes. Lovable: Maybe (gets slow). Bolt: No (not designed for it).

Which one has the best community?

All three have communities. Discord servers, Twitter, Reddit. All active.

Which one updates most frequently?

All update monthly. Features improve constantly.

Can teams use these?

Yes. All have collaboration features.
