Helping Teams Ship 10x Faster

One of the most important extensions for any IDE out there - has been a game changer for how I work over the past few months. I'm extremely grateful to the Cline team for the work they're putting in to push out meaningful features.

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.
