Products that do what Newzly-phantom – Asynchronous type-safe Scala DSL for Cassandra does
At newzly we use Cassandra for a variety of services. We loved Foursquare Rogue for MongoDB and we created a similar tool for Cassandra. Phantom is still in its early stages, but we look forward to your feedback and contributions!

I’ve been experimenting with building a Node.js HTTP framework using Rust + Hyper with N-Api. The project started as a fully synchronous server, but I recently patched it to support async (Tokio/Hyper). That change alone nearly doubled throughput in benchmarks. What’s different: * Built directly on Hyper, no heavy abstraction * napi glue for Node.js bindings * Minimal core (sync and async engines side-by-side) * Focused on raw performance, not plugins (yet) This is still experimental and not production-ready. I’d like feedback on: * Async API design — does it feel ergonomic? *…

Show HN: SerenDB – Neon PostgreSQL fork optimized for AI agent workloads We forked Neon to make database operations faster and safer for AI agents. The goal is to enable instant experimentation with production data and catch prompt injection attacks before they hit your DB. The open-source repo is at https://github.com/serenorg/serendb The coolest current features are: 1. Time-travel queries: Query your database as it existed at any timestamp. SELECT * FROM orders AS OF TIMESTAMP '2024-01-15 14:30:00'. Essential for debugging agent decisions and auditing what data an…

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, everyone. Three months ago, I started building my first GoLang package, VarMQ. In this short period, I gained a significant amount of traction from the community, and it resulted in over 140 stars on GitHub. A week ago, to check how it performs, I ran benchmarks with a similar package, Pond, which has been managed for years. Pond is not a message queue, though; however, it can be compared to VarmQ since it shares some similarities, except for its storage system. From the benchmarks, I got surprising results, which are that Varmq is taking 50%+ less memory than Pond and also has good…

I built GoSMig for my own projects and open-sourced it in case it helps others. It’s a tiny generic library (no external deps except golang.org/x/term) for writing SQL migrations in Go with compile-time checks. It supports transactional and non-transactional migrations, rollback, status, version, and a small CLI handler so you can ship your own migration binary. Why another migrator? - Minimal API, no DSL or file layout to learn - Type-safe via Go generics - Works with database/sql and sqlx out of the box - Should work with any db library (or wrapper) that implements some…

Hi HN, I've built `goliteql`, a fast and lightweight GraphQL executor and code generator written in pure Go. It parses GraphQL schema and queries, validates them, and executes resolvers without using reflection. It also supports introspection and generates Go code from a GraphQL schema. Why I built it: - I wanted a fast, minimal alternative to gqlgen - Easy to embed in WASM or microservices - Focused on simplicity and performance (4x faster in benchmarks)

We open-sourced the TLA+ and Fizzbee verified spec behind Ursa's storage engine. Verification across ~200K states caught a design bug that years of production missed. We then handed the spec to Claude Code — it produced a working Rust implementation (concurrent producers, compaction, fencing) without back-and-forth. We think verified specs are the best harness for coding agents: open-source the spec, let anyone implement it.

If we want better web3 experiences, developers need better tools. RPC nodes are really good at executing transactions, however they are notoriously cumbersome to set up, and reading large chunks of data is not very efficient: To show a list of transactions and receipts, nodes have to re-execute smart contract code on entire blocks. For every read call. Not great at scale. Which is why everyone is building ETLs to move data from the chain into their own database. This GraphQL API is our first step in allowing developers to spend more time on building product, rather than ETL infrastructure.

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…

Hi HN, we’re Jessie and Eric. We’ve been baking away at Cakework (https://www.cakework.com/), which is a way to build async backends without needing to manage cloud infrastructure. Cakework is for operations that take time or more compute, like file processing, report generation, or machine learning. Devs write backends as Python functions and deploy them with our CLI. They use our client SDKs to make requests, get status, and get processing results. Each request runs with its own CPU and memory parameters in its own microVM, with no timeouts. Devs can query for failures and…
