It looks like two companies that make technology are having a disagreement. One company, called Figma, sent a letter to another company, called Lovable, and told them to stop doing something.

The letter tells Lovable to stop using the name "Dev Mode" for a new part of their product. Figma has a feature with the same name, and they made the name official last year.

It's interesting that 'dev mode' is a common name in many products for people who write software. It's like an 'edit mode'. Big companies like Apple, Google, and Microsoft have features called 'developer mode' that people often call 'dev mode' in their information.

Many people use the words "dev mode." For example, a company used it in their products a long time ago. It is also a common name for a feature in many free computer programs.

Figma said that only the short name 'Dev Mode' is protected, not the full name 'developer mode'. It's like protecting the word 'bug' when you mean 'debugging'.

Figma wants to keep their word special. So, they must send letters to people who use it. If they don't protect the word, it might become a normal word that anyone can use. Then, Figma cannot stop others from using it.

Some people online think this word is too common and should not have been a registered name. They say Lovable should do something.

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

We will see if Figma takes legal action. Figma is also busy with other things. For example, Figma is planning to sell shares to the public soon. If Figma takes legal action against Lovable, it might cost a lot of money for the Swedish company. Lovable is a new company that recently got $15 million from investors.

Also, Lovable is getting known for something called 'vibe coding.' This is when you can write what you want, and the product makes it, even the code. They added a new part called 'dev mode' a few weeks ago so you can change the code.

Lovable says it is like Figma, and you can use it without hard work. Many new companies are using it.

So this is not just about a company's name. It is also a bigger 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 said they agree. They told TechCrunch that Figma did not send legal letters to companies like Microsoft because their products are different.

Osika from Lovable said that Figma should make their product better and not focus on marketing names. He also said that Lovable is getting customers from Figma and other old design tools.

Figma's boss, Dylan Field, said last month that he wasn't worried about these new design tools.

Field said people like vibe coding because it is fast. But you also need to help people start and finish their work. This is the problem for design and code.

Osika also looks ready to compete. When he showed the letter from Figma on X, he used the smiling face.
