Clace – Application Server with support for scaling down to zero
I have been building the open source project https://github.com/claceio/clace. Clace is an application server that builds and deploys containers, allowing it to manage webapps in any language/framework. Compared to application servers like Nginx Unit, Clace has the advantage of being able to work with any application, without requiring any dependency or packaging changes. Clace provides a blue-green staged deployment model for apps. Not just code changes, even configuration changes are staged and can be verified before being made live. Clace is not a PaaS solution,…
Clace – Application Server with support for scaling down to zero launched on September 11, 2024 with 72 votes, #548 of 5,281 launches that month and more than 90% of that year's launches. The site was still online in September 2026, 2 years on.
In plain words
Clace is an open-source application server that builds and deploys containers to manage web applications written in any language or framework. It supports blue-green staged deployments where code and configuration changes can be verified before going live. Unlike similar tools, Clace requires no dependency or packaging changes to applications. It includes a built-in reverse proxy and can scale down to zero, but focuses solely on application deployment rather than managing databases or auxiliary services.

Talanoa▲346Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…
