“Daniel Stenberg shared his open source story for the book maintaine.rs, recounting the remarkable journey that began with a simple tool in 1996 and grew into the widely-used cURL project. As its founder, Daniel helped pioneer the open source movement from its early days, building a tool that remains essential to the internet’s infrastructure. Grateful for his contribution to the book and for his lasting impact on open source.”

Polhem Prize
The Swedish Association of Graduate Engineers
Everything that is connected needs to exchange information. Twenty years ago, Daniel Stenberg started working on what we now call cURL. Since then he has spent late evenings and weekends, doing unpaid work to refine his digital tool. It consists of open source code and allows you to retrieve data from home page URLs. The English letter c, see, makes it "see URL".
