What it does
Cloudflare Workers lets you run JavaScript on Cloudflare’s edge, deploying globally to over 120+ data centers around the world in less than 30 seconds. Your code can intercept and modify any request made to your website, make outbound requests to any URL on the Internet, and replace much of what you might need to configure your CDN to do today.
Build and deploy serverless applications across Cloudflare

I've been working on this for some time now, starting with vm2, then deno-core for 2 years, and recently rewrote it on rusty_v8 with Claude's help. OpenWorkers lets you run untrusted JS in V8 isolates on your own infrastructure. Same DX as Cloudflare Workers, no vendor lock-in. What works today: fetch, KV, Postgres bindings, S3/R2, cron scheduling, crypto.subtle. Self-hosting is a single docker-compose file + Postgres. Would love feedback on the architecture and what feature you'd want next.

I've been making JavaScript sandbox alone for 6 years2022 · playcode.io · ▲397Hi HN! Thanks for your attention to my post.

I got cold many times, depressions, burned out, yet still alive and finished it. Many guys helped me with an advice. Many users give a lot of positive feedback. There are 200,000 monthly unique users. I work full time now because of the freemium business model. To be honest - I am happy after many years of hard work.

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…
