It's interesting that 'dev mode' is a name used in many computer programs for people who write software. It's like a way to change things. Big companies like Apple, Google, and Microsoft have features officially called 'developer mode'. People often call it 'dev mode' in books and guides.

The name "dev mode" is used a lot. For example, Atlassian used it in their products before Figma. It is also a common name in many free software projects.

Figma told TechCrunch that their special name 'Dev Mode' is only for the short version, not the full name 'developer mode'. It's like using the word 'bug' when you mean fixing problems.

Because Figma wants to keep the word for itself, it has to send letters telling people to stop using it. If Figma does not protect the word, it could become a normal word that anyone can use, and then its trademark will not work.

Some people online think this name is too common. They say it should not be a trademark and that Lovable should fight.

Anton Osika, the boss of Lovable, told TechCrunch that his company will not change the name of the feature. Figma wanted them to change it, but they said no.

We will see if Figma does more. Figma is also busy with other things. Last Tuesday, Figma said it wants to sell shares to people for the first time. But if Figma goes to court, fighting a legal case in another country could cost a lot of money for the new Swedish company, Lovable. Lovable got $15 million in February to start its business.

Lovable is becoming popular because of something called "vibe coding." This is when you write what you want, and the product makes it, even the computer code. A few weeks ago, they added a feature called "dev mode" so you can change the code.

Lovable says it is like Figma, and many new companies are starting to use it.

So this is not just a fight about a name. It's also a bigger company getting ready to fight a small, new company that is annoying. Figma was worth $12.5 billion about a year ago.

Someone from Figma seemed to agree. They told a website called TechCrunch that Figma has not sent letters to other companies like Microsoft to stop using the word because their products are very different.

Osika from Lovable said that Figma should make their product good and not just do marketing. He also said that Lovable is getting customers from Figma and other design tools made before new AI technology.

When the CEO of Figma, Dylan Field, talked to Garry Tan, he said he didn't think vibe coding products were a big danger.

Field said people like vibe coding because it is fast. But it should also help people finish their projects, not just start them quickly. This problem is not just for design, but also for code.

Osika also looks ready to compete. He put Figma's letter on X and used the smiling face emoji.
