24 alternatives to Coze – cryptographic JSON messaging specification
Coze is open source under the BSD 3 license, and the reference implementation is written in Go. You can play with Coze using the online tool (https://cyphr.me/coze). There is also the simple tool (https://cyphr.me/coze_verifier_simple/coze.html). This is an example coze: { "pay": { "msg": "Coze Rocks", "alg": "ES256", "iat": 1623132000, "tmb": "cLj8vsYtMBwYkzoFVZHBZo6SNL8wSdCIjCKAwXNuhOk", "typ": "cyphr.me/msg" }, "sig": "Jl8Kt4nznAf0LGgO5yn_9HkGdY3ulvjg-NyRGzlmJzhncbTkFFn9jrwIwGoRAQYhjc88wmwFNH5u_rO56USo_w" } Coze also defines a key format allowing…

Hi HN, Nick here. We’re launching OpenKnowledge (https://openknowledge.ai/), a “what you see is what you get” markdown editor that has direct integrations with Claude, Codex, and other agents. Available as MacOS app or Web UI+CLI. Fully free/local and OSS. We built this because we wanted a Notion-like experience for writing and sharing markdown files across our team. Obsidian is the best alternative we tried, but found it doesn’t have a true WYSWIG UI and it didn’t integrate well with Claude/Codex outside of community plugins. So we built OpenKnowledge. It takes…

I usually build web games in C++, but using Emscripten always felt like overkill for what I was doing. I don't need full POSIX emulation or a massive standard library just to render some stuff to a canvas and handle basic UI. The main thing I wanted to solve was the JS/WASM interop bottleneck. Instead of using the standard glue code for every call, I moved everything to a Shared Memory architecture using Command and Event buffers. The way it works is that I batch all the instructions in WASM and then just send a single "flush" signal to JS. The JS side then reads everything directly out…

Nango (https://github.com/NangoHQ/nango) provides pre-built OAuth flows, secure token storage and automatic refreshes for 40+ APIs and counting. Why we built Nango: We built Nango to solve the pain of accessing OAuth APIs. Despite OAuth being a standard protocol in theory, it remains a major burden to implement it, even with the help of a library. You still need to add endpoints and logic to your app for the server-side dance, implement token refreshes, build & secure your token storage, deal with redirects on the frontend etc. But the worst part is that (almost) every…

Hey everyone, I had posted about my project https://adzejs.com a couple of years ago and it was met with a lot of interest, so I'm writing about the major v2 update that's just been released to see if anyone is interested. What makes Adze interesting compared to other logging libraries like pino, bunyan, winston, etc? Adze is universal. This means that Adze will "just work" in all of your environments. This is especially handy when working with SSR projects like sveltekit, nuxt, next, etc. You can also use Adze with Bun or Deno without any special adaptations or considerations.…

Hey HN, we’re building an open specification that lets agents discover and invoke APIs with natural language, built on the OpenAPI standard. agents.json clearly defines the contract between LLMs and API as a standard that's open, observable, and replicable. Here’s a walkthrough of how it works: https://youtu.be/kby2Wdt2Dtk?si=59xGCDy48Zzwr7ND. There’s 2 parts to this: 1. An agents.json file describes how to link API calls together into outcome-based tools for LLMs. This file sits alongside an OpenAPI file. 2. The agents.json SDK loads agents.json files as tools for an LLM that…

Hey HN, I find myself reaching for tools like it-tools.tech or other random sites every now and then during development or debugging. So, I built a toolkit with a sane and simple CLI interface for most of those tools. For the curious and lazy, at the moment, ut has tools for, - Encoding: base64 (encode, decode), url (encode, decode) - Hashing: md5, sha1, sha224, sha256, sha384, sha512 - Data Generation: uuid (v1, v3, v4, v5), token, lorem, random - Text Processing: case (lower, upper, camel, title, constant, header, sentence, snake), pretty-print, diff - Development Tools: calc, json…

We've been building Crust (https://crustjs.com/), a TypeScript-first, Bun-native CLI framework with zero dependencies. It's been powering our core product internally for a while, and we're now open-sourcing it. The problem we kept running into: existing CLI frameworks in the JS ecosystem are either minimal arg parsers where you wire everything yourself, or heavyweight frameworks with large dependency trees and Node-era assumptions. We wanted something in between. What Crust does differently: - Full type inference from definitions — args and flags are inferred automatically. No…
