In plain words
CodeSandbox is a cloud development platform that lets developers write, test, and deploy code from any device. It provides isolated development environments called sandboxes that can run any type of code safely without affecting the system, and supports millions of concurrent virtual machines. The platform features fast VM provisioning, cloning, and snapshot restoration in under 2 seconds, allowing developers to resume work after inactivity without losing progress. It's designed for teams collaborating on projects of any size.

From the sources
Use our APIs to create isolated development environments (sandboxes) that can run any type of code you need. Every environment runs in isolation, so you can safely run untrusted code without it affecting your system. We can handle millions of concurrent VMs and make it easy to provision, manage and decommission VMs. Resume development within the same sandbox after periods of inactivity. With no loss thanks to our snapshots. Our microVM infrastructure allows us to spin up entire VMs, clone them and restore snapshots within 2 seconds. Gain total control over periods of inactivity before auto hibernation kicks in. Give agents a sandbox to resolve user prompts, or create autonomous agents…from codesandbox.io

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…
