24 alternatives to Open Fire Serverless CI
Hello, HN community, I'm really excited to show you Open Fire a serverless CI, how does it work? relying on serverless technologies (firecracker) we can spin up a new VM in less than 200 ms running in a more powerful and newest CPU on the market, just change 1 line of code on your GitHub Actions Workflow and you're up and running! You can see our use case, where we implemented Open Fire in the NextJS repo taking down build time from 1 hour 17 minutes to 26 minutes which is a 66 % of improvement without any engineering effort! [1] The value of a CI/CD Pipeline is inversely proportional…
Open Fire Serverless CI is a continuous integration tool that uses Firecracker virtual machines to execute build jobs in less than 200 milliseconds on high-performance CPUs. Users integrate it into GitHub Actions… Below are 24 products that do a similar job, ranked by how close each is in meaning and then by launch-day votes. Prices are shown for the 1 we have checked on their own sites, 1 of them free or with a free tier. Open Fire Serverless CI launched in 2023; newer entries below may have overtaken it.

Hi HN! I'm Jean-Paul, the creator of Fire CI (https://fire.ci). I've been a dev for 10 years and building Fire CI for the past 6 months. Fire CI is a server that runs local builds in Docker on your own computer. It uses an installable agent to broker the builds with GitHub and also co-ordinates builds between your local server and other members of your team (optional). It's fast because there is no queueing and a tiny piece of your computer is more powerful than most hosted or rented cloud servers. It's scalable by design: each developer brings his own computing power. And IMHO the…

I wanted to see how fast an isolated code sandbox could start if I never had to boot a fresh VM. So instead of launching a new microVM per execution, I boot Firecracker once with Python and numpy already loaded, then snapshot the full VM state. Every execution after that creates a new KVM VM backed by a `MAP_PRIVATE` mapping of the snapshot memory, so Linux gives me copy-on-write pages automatically. That means each sandbox starts from an already-running Python process inside a real VM, runs the code, and exits. These are real KVM VMs, not containers: separate guest kernel, separate guest…

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.

Hi HN! Thanks for your attention to my post. It was a big challenge to run most of Node.js packages in browser, fast moreover. Virtual File system, resolve import/export. 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.

I'm building Kedge, a globally distributed platform for stateful serverless apps. Here's how you make a simple static site: `echo '# Hello world!' | ssh kedge.dev` I helped build Fly.io for 4 years and shared enthusiasm for the founders' vision of a 'global Heroku'. While there, I wrote "The Serverless Server" (https://fly.io/blog/the-serverless-server/) as a study of Lambda and a sketch of a modern serverless product built around lightweight VMs. That essay was the initial inspiration for Kedge. Kedge has a fast VM orchestrator that can create code sandboxes or…

Hi HN! Sina here. i wanted to share this open source project (apache 2.0) that i've been working on for the past month or so. it's called hotcell and it lets you create/pause/manage sandboxes on any device (your laptop, linux vm, bare metal). i've tested it against various benchmarks that i found on computesdk (https://www.computesdk.com/benchmarks/sandboxes/) as well as the one shared by dax (cofounder of open code) on twitter recently (link to his original thread and my reply https://x.com/sinasanm/status/2078158598996443346) and…

Hi HN! We’re Yann, Edouard, and Bastien from Koyeb (https://www.koyeb.com/). We’re building a platform to let you deploy full-stack apps on high-performance hardware around the world, with zero configuration. We provide a “global serverless feeling”, without the hassle of re-writing all your apps or managing k8s complexity [1]. We built Scaleway, a cloud service provider where we designed ARM servers and provided them as cloud servers. During our time there, we saw customers struggle with the same issues while trying to deploy full-stack applications and APIs resiliently. As…
