Products that do what Verani – Socket.io-like realtime SDK for Cloudflare does
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…

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…

Actor Kit is a library for running state machines in Cloudflare Workers, leveraging XState for robust state management. It provides a framework for managing the logic, lifecycle, persistence, synchronization, and access control of actors in a distributed environment. Key features include: - Persistent, distributed state management - Type-safe events and state with TypeScript and Zod - Real-time updates and seamless server-to-client state transfer - Access control and secure data management - Framework-agnostic with examples for Next.js and Remix integration - Actor lifecycle management in…

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.

I recently finished a round of tweaks on my barebones mud-server and thought HN might be interested. https://github.com/endgame/MudCore It sits somewhere between socketmud and a full mud like tbamud in that it handles all the socket work and telnet negotiation, but it makes no assumptions about anything else. The other interesting thing is that it can talk to other services using ZeroMQ. I'm interested in reactions, particularly in terms of coding style, documentation quality and so on. It's my main "presentation piece" so far, in that it's some of the first code I actually feel proud to…

I built a CLI tool that turns codebases and PRs into diagrams so you can quickly understand how things fit together. Originally made it because I couldn't follow my own AI-generated repos. Just shipped a big update: - Switched from D2 to Mermaid for rendering - Tree-sitter AST parsing + agentic flow instead of raw LLM calls. ~50x faster. - Works on any GitHub repo or PR, not just local - Dropped the web frontend, it's just a CLI now - Published as a pip package Still a ton to improve and I'm building fast. Feedback, issues, PRs all welcome.

Started this because configuring Fabric8 for EKS was driving me crazy. Building a client that auto-detects your environment (IAM roles, profiles, local configs) so you don't have to wire it all up manually. Still pretty early and building for EKS right now. Long way to go, but putting it out there early to see if others have hit the same problems or want to help shape where this goes.

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…

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…

Hi! Recently I've launched - mybfio.io - platform for software reviews with social network aspect. Prehistory Many great system are already in place that allow people to search and rate software products, including the site I am publishing this post on. However I have always felt that those systems are not specifically centered around product/software development lifecycle (releases, real users feedback over a product entire lifetime, so on) and often too broad or not designed specifically for that type of work, which is ok. Why? As an opensource author I would like to have constant…

I spent the past few weeks making an open source cloud code editing environment with an AI copilot and multiplayer collaboration! It's fully self-hostable in 5-10 minutes. There's a lot of minor improvements to be made, and some are already listed in the Github issues. Let me know what you think and feel free to try it out.

At Laminar (https://github.com/lmnr-ai/lmnr) we're building open source AI observability platform in Rust. We obsess over instrumentation DX for our Python and TS SDKs and in this new blog we outline how we made the most seamless way of instrumenting recently released claude agent sdk

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,…

We open-sourced catsu, a Python client for embedding APIs. The problem: every embedding provider has a different SDK with different bugs. OpenAI has undocumented token limits. VoyageAI's retry logic was broken until September. Cohere breaks downstream libraries every release. LiteLLM's embedding support is minimal. catsu provides: - One API for 11 providers (OpenAI, Voyage, Cohere, Jina, Mistral, Gemini, etc.) - Bundled database of 50+ models with pricing, dimensions, and benchmark scores - Built-in retry with exponential backoff - Automatic cost tracking per request - Full async support…

Hi HN, We're a new Bay Area startup aiming to connect all of your things visually - supporting multiple triggers (AND and OR), multiple actions, cascading flows, etc. We're already integrating with dozens of services, both physical and digital - SmartThings, LIFX, Hue, Jawbone, Withings, Misfit, Dropbox, Google Drive, and the list goes on. We're really hoping to get some additional beta testers. We're on iOS only for now - so if you have an iPhone and want to give it a shot, get on our invite list @ https://www.stringify.com and we'll send you a TestFlight invite in the next few…

We have built Tarit as a hypervisor built from ground up for running AI agent and RL environments. It is based on rust-vmm and can be used as a replacement for firecracker. Firecracker was built to serve a different need of primarily serverless compute and hence does not have primitives like live snapshots without pausing the VM operations. We also provide a basic orchestrator that handles placement of the microVMs, creating clusters with HA, maintaining a warm pool of VMs, and takes care of setting up networking and monitoring. Our benchmarks on a metal instance shows an acquire VM from…
