24 alternatives to Verani – Socket.io-like realtime SDK for Cloudflare
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…

I've been obsessed for the past ~year with the possibilities of talking to LLMs. I built a bunch of one-off prototypes, shared code on X, started a Meetup group in SF, and co-hosted a big hackathon. It turns out that there are a few low-level problems that everybody building conversational/real-time AI needs to solve on the way to building/shipping something that works well: low-latency media transport, echo cancellation, voice activity detection, phrase endpointing, pipelining data between models/services, handling voice interruptions, swapping out different…

Hey HN! I’ve written a bunch of WebSocket servers over the years to do simple things like state synchronization, WebRTC signaling, and notifying a client when a backend job was run. I realized that if I had a simple way to create a private, temporary, mini-redis that the client could talk to directly, it would save a lot of time. So we created DriftDB. In addition to the open source server that you can run yourself, we also provide https://jamsocket.live where you can use an instance we host on Cloudflare’s edge (~13ms round trip latency from my home in NY). You may have seen my…

I've built this to make it easy to host your own infra for lightweight VMs at large scale. Intended for exec of AI-generated code, for CICD runners, or for off-chain AI DApps. Mainly to avoid Docker-in-Docker dangers and mess. Super easy to use with CLI / Python SDK, friendly to AI engs who usually don't like to mess with VM orchestration and networking too much. Defense-in-depth philosophy. Would love to get feedback (and contributors: clear & exciting roadmap!), thx

Hi HN, I built Ayder — a single-binary, HTTP-native durable event log written in C. The wedge is simple: curl is the client (no JVM, no ZooKeeper, no thick client libs). There’s a 2-minute demo that starts with an unclean SIGKILL, then restarts and verifies offsets + data are still there. Numbers (3-node Raft, real network, sync-majority writes, 64B payload): ~50K msg/s sustained (wrk2 @ 50K req/s), client P99 ~3.46ms. Crash recovery after SIGKILL is ~40–50s with ~8M offsets. Repo link has the video, benchmarks, and quick start. I’m looking for a few early design partners (any…

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…

Last week Cloudflare released Cap'n Web [1], a schema-free capability-based RPC protocol. I built capn-rs this week - a Rust implementation with full wire protocol compatibility. Links: GitHub: https://github.com/currentspace/capn-rs Crates: https://crates.io/crates/capnweb-server API docs: https://docs.rs/capnweb-server What's working: Wire compatibility verified via integration tests against TypeScript reference Multi-transport: HTTP batch, WebSocket, WebTransport (HTTP/3) Complete IL (intermediate language) expression evaluator…

Inspired by the recent justfuckingusetailwind.com, I built a similar "love letter" to the Cloudflare ecosystem. I find myself reaching for Workers, R2, D1, and KV for almost every project lately, so I wanted to capture that sentiment in a single, slightly over-the-top page. It’s a simple side project, but the stack is: - Vite + TypeScript - Biome + Ultracite - Deployed (obviously) on Cloudflare First draft in Claude, the copy was drafted with Grok to get that specific tone, then I used Google's AI Studio to accelerate the build with touch up's in Cursor. Link:…

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…

Hey HN, I'm so excited to finally share with you what I've been working on recently. One month ago I asked my audience what they wanted to learn about Websites, APIs and Servers security [0]. From the feedback, I've identified a few recurring pain points that I've started to address (and many more) in this new book. From theory to practice, you will learn how low-level network and security protocols work. How to configure Cloudflare to secure and scale your web applications. How to create serverless applications and which database to chose with serverless functions. How to optimize your…

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…

Hey folks, I am finally posting a Show HN post for a project I have been working on for several months now, and it's in a state where I already get a lot of value myself, so I am happy to share broadly. The pitch line is: "Skybear.NET is a managed platform automating Synthetic HTTP API testing." At the moment, the main source file format supported for your API tests are Hurl.dev files [1]. Hurl is a CLI tool wrapping `curl` and it's really awesome. At least check that out :) I am not affiliated directly with the Hurl CLI tool, and the platform I am building provides full Hurl compatibility.…
