Vibe coding isn’t just another buzzword on the internet — it seems to changing how programming is done in the real world.
Cursor co-founder Aman Sanger has said that the IDE was being used to write 1 billion lines of code a day. He implied that this was a sizable chunk of all the code that was being written globally on a daily basis.
“Cursor writes almost 1 billion lines of accepted code a day. To put it in perspective, the entire world produces just a few billion lines a day,” Sanger posted on X. He added that 40% of code committed by professional engineers using Cursor was AI-generated through Cursor.
Cursor was founded in 2022 by MIT graduates Michael Truell, Sualeh Asif, Arvid Lunnemark, and Aman Sanger. Cursor was launched in 2023 as an AI-powered integrated development environment (IDE) for Windows, macOS, and Linux and was forked from the open-source VS Code editor. Cursor uses third-party AI models, such as Claude Sonnet 3.7 and Google Gemini 2.5 Pro to help coders use AI to write code. Cursor was last valued at $2.5 billion.
Cursor has been the breakout star of the vibe coding phenomenon, in which programmers simply give instructions in English to an IDE like Cursor, which then writes the actual code. Programmers can give successive English commands to build their code without even looking at what the created code looks like. This allows developers to quickly build code and MVPs, and even work on existing codebases much faster than they’d traditionally been able to.
And Cursor has seen interest from some of the top tech companies out there. OpenAI had explored acquiring Cursor earlier this year, but is now seen to be looking to acquire Windsurf — a Cursor competitor — instead for an estimated $3 billion. And if the numbers are really what the company claims — 1 billion lines of code per day does seem to be massive — Cursor might have the opportunity of becoming a category-defining tech product in the years to come.
