Ardan Labs announces they have secured the acquisition of Caddy Server with Apilayer. Caddy is a leading open-source extensible web server platform (written in the Go programming language) that has secured trillions of network connections around the globe. Apilayer a leading provider of cloud-based API and Software-as-a-Service (SaaS) brands.

Matt Holt started building Caddy in 2014 as a way to provide automatic and default HTTPS support for websites. Since then, Matt and the open-source community has built Caddy to provide easy, powerful, and dynamic configuration, with an extensible framework that provides high levels of resilience. “I’m pleased to look back now and see that over 300 people have collaborated to make privacy the default for the web,” Matt explained. “We’ve raised the bar for similar products and made TLS more accessible and reliable than ever. Working with Ardan Labs and now Apilayer to continue the project has been a great boon to the open-source community.”

Bill Kennedy, the Managing Partner at Ardan Labs had this to say: “I am very happy for Matt, Caddy, and the Go community. I feel blessed that Ardan Labs was able to support Matt and the project at a time when it was needed most. We at Ardan always believed in Matt and the full potential of the product, and this acquisition by Apilayer shows that supporting free open-source software can result in positive outcomes. I am most thankful to Apilayer because now Caddy’s future is secure and companies can feel confident that the product will be available for many years to come.”

“As a developer-centric company, our leading API solutions and products are used to power automation processes for hundreds of thousands of customers, ranging from small websites, SMBs, all the way to Fortune 500 enterprises. The acquisition of Caddy brings us one step closer to the developer community, and gives us the opportunity to continue building on the innovative platform that the Caddy team has developed," said Julian Zehetmayr, Founder & CEO of Apilayer.

Julian also said, “Caddy’s innovative technology and thriving open-source community were one of the most attractive elements in this partnership. Caddy will remain a separate and independent open-source brand and will continue to be directed by its original author, Matt Holt. Apilayer is committed to continued innovation, increased investment, and support for the project over the years to come.”
