Two technology companies, Figma and Lovable, might be starting a disagreement. Figma sent a letter to Lovable telling them to stop doing something.

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

It's interesting that 'dev mode' is a name often used in products for people who write computer programs. It's like an edit mode. Big companies like Apple, Google, and Microsoft have features officially called 'developer mode' which are sometimes called 'dev mode' in their information.

Many people use the name "dev mode". For example, Atlassian used it a long time before Figma. It is a common name in many free software projects.

Figma told TechCrunch that their special name is just for the short name "Dev Mode." It is not for the full name "developer mode." This is like saying you own the word "bug" when you mean fixing computer problems.

Figma needs to send letters to people using the word because they want to keep it as their special word. If they don't protect it, the word could become a normal word that anyone can use, and they would lose their right to it.

Some people online think the name 'Lovable' is a common word. They say it should not have been allowed to be a trademark. They also say Lovable should fight.

Anton Osika, who is the boss of Lovable, told TechCrunch that his company will not change the name of the feature. He said this is because Figma asked them to change it, but they don't want to.

We will see what Figma does. Figma is also busy with other things. This week, Figma said it sent secret papers to become a public company. 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.

Another interesting thing is that Lovable is becoming popular for something called "vibe coding." This is when people write what they want, and the product makes it with code. A new part was added recently so people can change the code.

Lovable says it is like Figma. On its website, it says designers can use Lovable to create designs easily, without the hard work of making prototypes in programs like Figma. Many new companies are using it.

So this is not just a problem with a name. It is also a bigger company getting ready to fight a smaller, new company. Around a year ago, Figma was thought to be worth $12.5 billion.

Someone from Figma seemed to agree.

Lovable's Osika said he thinks Figma should make their product better and not spend time on marketing. He also said that Lovable is taking customers from Figma and similar tools that were made before new AI technology.

Last month, someone asked the head of Figma about the danger of "vibe coding" products. He said it was not a big problem.

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

Osika also looks ready to compete. He shared the letter on X and used a smiling face picture.
