Lovable, Bolt, Cursor, v0: what is each one for, and when to switch tools?

Lovable, Bolt, Cursor and v0 do not replace one another: they are not all meant for the same job. Rather than looking for the "best" one, it is better to understand which type of tool fits your need, then decide on a few simple criteria.

A warning first. This field moves very fast: tools change how they work, their limits and their offers within months, and new ones appear. This article describes types of tools, not a snapshot of the market. Before choosing, always check their current state on their website and in their documentation, or ask someone who uses them.

The analogy: a toolbox, not a universal hammer

To fit out a room, you do not use the same tool to measure, drill or paint. None is "better": each is made for one gesture. AI building tools work the same way.

Three types of tools

• App generators from a description. You describe what you want in a conversation, the tool produces a whole application, usually hosted for you. It is often the simplest way to get something visible quickly. Lovable and Bolt are often placed in this family.
• Assistants inside the code editor. They help a person who reads and writes code: suggestions, changes across several files, explanations. They assume you can steer what they produce. Cursor belongs to this family.
• Interface generators. They mostly produce screens and visual components, to be integrated into a project. v0 is often mentioned here.

This classification is a simplification: the boundaries move, and each tool regularly adds features from the other families. Check what each one does today.

The criteria for deciding

1. Your technical level. If you do not read code, a tool that produces a complete application suits you better than an editor assistant, which assumes you can judge the result.
2. The goal. A demo, a prototype to test the idea, or a product that will serve real users: the requirements are not the same.
3. Who owns the code, and where it lives. Can you export it, host it elsewhere, hand it to a developer? Check before committing, not after.
4. Sensitive data. As soon as you handle accounts, payments or personal information, mistakes cost far more.
5. What comes next. Who will evolve the product in six months, and in which tool?

When to change tools, or method

Changing tools is not always the answer. A few signals deserve a pause:

• every fix brings up another problem, and you are going in circles;
• you ask the tool to fix what it produced itself, with no progress;
• you are nearing real users, real data, real payments;
• nobody understands how the product is built any more.

In those cases, another tool does not solve the underlying issue. A person who knows these topics needs to review what exists: security, data access, structure. Lovable, Bolt, Cursor: What Changes When AI Writes Code says the same. To see where the line lies, read Vibe coding: how far to go before calling a developer.

To decide: questions to ask yourself

• Is my goal to test an idea or to serve real users?
• Am I able to read and judge what the tool produces?
• Can I export my code and host it wherever I want?
• Will there be personal data or payments?
• Who will maintain this product in six months?
• Have I checked the tool's current state, and not only what was said about it a year ago?

Key takeaway

These tools are not ranked from best to worst: they are types of tools for different jobs. Choose according to your level, your goal and the sensitivity of the data, check their current state, and have the result reviewed before welcoming real users.

And for your product?

If your application was built with one of these tools and is nearing real users, a code audit tells you what holds, what is fragile and where to start. We can talk it through in a 30-minute conversation.
