Products that do what Vask – Pusher-compatible WebSockets on Cloudflare, no fan-out fees does
Howdy HN, Ashley here. Most of my projects use realtime, but the jump from 'free' to 'paid' on existing platforms stressed me out, and I didn’t want to self-host soketi or sockudo. So I built Vask, a websocket platform built on top of Cloudflare Workers, Durable Objects, KV storage, and analytics engine, so I can get sort-of infinitely scalable, low latency, and low-cost websockets. I noticed that ‘fan-out’ is pretty cheap with Cloudflare, so Vask can bill per message sent rather than message received (no fan-out cost), which is great for certain workloads, and quite different to existing…

Hi HN, I built Verani, an experimental realtime SDK for Cloudflare Actors (Durable Objects). The goal is to bring a familiar, event-based DX (rooms, emit, channels, lifecycle hooks) to Cloudflare Durable Objects, while handling hibernation correctly. It focuses on - Socket.io-like semantics on top of Durable Objects - Proper Actor hibernation handling (WebSockets survive, state is restored) - Typed API with explicit tradeoffs. It’s early and experimental, but functional. I built it mainly to explore DX and state management patterns on Cloudflare Actors, and I’d love feedback from people…

Hey guys and gals! I'm learning Go at the moment and LOVING it. I was hoping to get constructive feedback on a project I'm working on - goatee - which is a notification server that utilizes Redis pub/sub and WebSockets. It's fairly bare-bones at the moment but I'm hoping to add in a lot more features as time goes on such as queueing and WebSocket channel subscriptions (via Go Socketio possibly).

I always find myself frustrated by how many steps I have to take to video chat with someone online. There's always too much software to download and install, and too many accounts to remember. The high-end, high-price Cisco conferencing systems I've used are especially fragile. So I built Vidless in a weekend for myself, and I hope you find it useful too. Just create a room and share the link, and you'll be chatting in seconds. You can invite several people (I haven't really tested a max yet), and chats on Vidless are always private. Enjoy!

Hi hackers! I'm a self-taught solo teenage dev ever wanted to show what you're doing right now on the internet? well I've been wanting to for a while, so I built Lynk, a lightweight macOS app that tracks your active apps, window titles, and daily usage in real time, and broadcasts that data over WebSockets. Oh and it also updates whenever you switch apps to connected clients! No SDKs, no APIs — just local tracking + a websocket endpoint you can ping from any language.

Hey HN, I'm a longtime reader and this is my first Show HN (exciting!) It's a collaboration between me and two friends, and we're building this upon another app we made called EmailYak, an API to receive email. We're trying something new and releasing the documentation to an app while we're still building it. We'd love feedback. Do you belong to any of these categories? 1) You've built an app with two distinct groups of users (say, people with cars and those looking for a ride) and they were able to communicate with each other. Did you expose personal email addresses? Did you send…

You might have heard that scaling WebSocket infrastructure is not an easy task. It was true–until recently. We built the open source real-time server, AnyCable, that deploys to Fly.io in one command (and configures itself), and the SDK for serverless JS/TS that allows you to build real-time features without any 3d-party PaaS. We call it a real-time server, because it has WebSockets and more, and it’s easy to run and scale. Here’s all you need to add real-time to your Next.js/Vercel app: – Deploy AnyCable to Fly.io with one command (see the docs) – In your Vercel app add one…

Hello HN! I am Ashley, author of the book Serverless Apps on Cloudflare, and I'm excited to share it with you and hopefully spread the awareness of the powerful and developer-focussed platform that Cloudflare has built, that I believe is currently flying under the radar! For years, I've been building applications on Cloudflare - from websites, to APIs, to Discord bots and everything in-between. The platform has grown hugely in the past few years, to the point it has all the essential building blocks for modern applications. It's also built with engineers in mind, the developer experience…

Over the past few months, as we scaled our internal AI Agents, we hit a dead end: Running LLM-generated arbitrary code in Docker is basically running naked on security due to container escape risks. But using full traditional VMs takes minutes to boot and eats too much memory to support high-density concurrency. We loved the developer experience of SaaS sandboxes on the market, but they are closed-source, expensive, and have too high a barrier to entry for self-hosting. So, our team decided to build our own. After months of grinding, using RustVMM and KVM, we built a blazing-fast,…

I wanted to free my time for working out and my family, so I built a social media scheduler that doesn't break all the time. It has cross-posting across all major social media platforms. The platform is built with NestJS, Kafka, Redis for the backend, Nextjs for the landing, and React with Vite for the frontend private part. I'd love to get your thoughts on what more inside would save you time from going to all those different platforms one by one.

Hey HN: Kaveh here, the founder of https://www.usage.ai/ We launched a new free tool to help engineers understand their AWS spend. Why? Because the way it's done now is a pain. DevOps and Software Engineers end up end up becoming cloud accountants or end up forking over a big % of their AWS bill for a tool to understand costs rather than focusing on business problems. Previous to founding Usage, I worked on high-performance computing research at JP Morgan Chase and as a software engineer at a number of smaller startups. Here's how this new tool works: It's fully self-serve and…

the cloud is a walled garden built for profit [ not efficiency ]. you’re paying for idle, autoscaling is too slow, and serverless is a scam. locked in, overcharged, and out of options. lttle.cloud is different. decentralized, open-source, and built for real performance [ sub-10ms cold start ], true pay-for-what-you-use pricing, and zero vendor lock-in. deploy anything as "serverless" from any docker image, no rewrites, no bullshit. powered by the blockchain and built in public, it’s transparent, efficient, and free from vendor lock-in. run your own private cloud or join the decentralized…

Hi HN, I’m one of the devs behind StarDesk, a P2P-first remote desktop we’ve been building for ~1 year. We started this partly out of frustration: some popular RDP tools haven’t seen meaningful updates in a long time, and long-standing issues are often left unaddressed. As devs, we really dislike software that stagnates once it “works well enough”. StarDesk is our attempt to do it differently. What we focus on: -P2P by default (relay as fallback) -Low RTT + low jitter > chasing max bitrate -Encoder / input path tuned for real-time interaction -Modern E2EE (TLS/DTLS) UX-wise, setup…

Hey everyone! I’ve developed a few tools that I wanted to share with the community: https://clipush.deno.dev A simple way to send web push notifications using cURL, making the process much easier to integrate into your workflow. (An experiment for personal usage.) https://request-bin.deno.dev A tool that acts as a real-time HTTP request debugger with SSE logging to track and analyze requests efficiently. (Created after requestb.in introduced limits on free accounts. Personally used for testing webhooks.) https://lock-states.deno.dev A service to manage lock…

Hello HN, Lucas here. I’ve been working with BigQuery for ~5 years, mostly in large (petabyte-scale) environments. Over time we ended up spending a lot of money and engineering effort just trying to understand where costs were coming from, why and how to optimize them. At some point we decided to stop, leverage all our past experience and spend a full cycle building tooling focused on cost visibility and optimization. The main goal was to regain ownership of cost data and make it possible to understand our cost structure in under a minute, while aligning the views of engineering and FinOps…

Strava doesn't provide a way for getting webhooks from your activities, so I wrote up a little application to do just that. Using: - Tailwind - Sveltekit - Netlify - Firebase/Firestore Check it out and let me know what you think. I don't have any expectations that Strava won't break it or keep me at the 1000 requests/day quota, but hey it was fun to make!

Hi everyone, it’s Alex, Simon, Felipe and the team from Unikraft.io We have built kraft.cloud, a millisecond cloud platform, where apps and services cold start, scale to zero and autoscale in milliseconds, ensuring you never pay for idle, can efficiently cope with traffic peaks, and don’t have to deal with complex cold start issues. As of today we are now in open early access! The platform (and we) come from research in the area of lightweight virtualization — trying to ask the question of how efficient cloud platforms could (or should) be while still retaining strong, hardware-level…
