Without a doubt the single greatest boost to my coding productivty, ever. Being able to explore new ideas and test innovative solutions in a fraction of the time has been invaluable to every project that has used Cline. I could not reccomend Cline any more than I do.

Cline has completely transformed the way I work as a developer. It's like having a highly skilled coding assistant available 24/7 right within my IDE. From generating and editing files to executing terminal commands and even debugging with headless browser capabilities, it handles everything with precision and ease.

Andrin FosterApril 18, 2025

AI companies are operating in arguably the most hotly contested market in human history. Earth shattering venture rounds incenting and empowering the brightest minds in the world in a winner take most (if not all!) race to the singularity.

Colonel John Boyd. If you've never heard of him, you're not alone. Today
