It looks like there is a problem starting between two tech companies. Figma sent a letter to a new company called Lovable, which uses AI. Figma told Lovable to stop doing something.

The letter says Lovable must stop using the name "Dev Mode" for a new part of their product. Another company, Figma, has a feature with the same name. Figma got the legal right to use that name last year, according to the U.S. Patent and Trademark office.

It's interesting because 'dev mode' is a common name in many products for people who write software. It's like a way to change things. Big companies like Apple (iOS), Google (Chrome), and Microsoft (Xbox) have features officially called 'developer mode' that people then call 'dev mode'.

Many companies and projects use the name "dev mode". For example, Atlassian used it before Figma. Also, many free software projects call it this.

Figma told TechCrunch that their special name 'Dev Mode' is only for the shortcut. It's not for the full name 'developer mode.' It's a bit like trying to own the word 'bug' when you mean 'debugging.'

Figma has to send letters to stop people from using the word. If they don't protect the word, it could become a common word that anyone can use, and they would lose their special right to use it.

Some people online think this word is too common. They think it should not be a trademark. They also think Lovable should fight.

Anton Osika, who is the boss of Lovable, told TechCrunch that his company will not change the name of the feature, even though Figma asked them to.

We will see if Figma takes this further. Figma is also thinking about other things. On Tuesday, Figma said it secretly gave papers to sell parts of the company to people. But if Figma starts a legal fight, it could cost a lot of money for the new company from Sweden, Lovable. Lovable got 15 million dollars in February.

Also, Lovable is becoming popular because of something called "vibe coding." This means you can write what you want, and the program will create it, including the code. A few weeks ago, they added a "dev mode" so people can change the code.

Lovable says it is like Figma. It says designers can use it without the boring work they do in tools like Figma. Many new companies are using it.

This is not only a fight about a name. It is also a big company getting ready to fight a small, new company that is causing problems. Figma was worth $12.5 billion about a year ago.

Someone from Figma seemed to agree.

And Osika from Lovable says that Figma should make their product good, not just advertise. He also says that Lovable is taking customers from Figma and other design programs.

Figma's CEO, Dylan Field, said it was not a big problem when he talked to Garry Tan from Y Combinator last month.

Field said people like vibe coding because it is fast. But he also said people need help to finish their work, not just start fast. He thinks this is a problem for design and code.

Osika also looks ready to compete. He shared Figma's letter on X and used a smiling face.
