Flux, Modern API Client
Native API client. AI built in, no key, no account.
What it does
0.2.0 makes the AI free to try: 100 actions a month, no API key and no setup. Before this you had to bring your own Anthropic key before you could see what it did, and most people never got that far. The CLI now embeds a JS engine and the same pm shim as the app, so collections that authenticate through a pre-request script finally run in CI instead of being skipped with a warning. Three assertion engines that had drifted apart are now one. Still Tauri, not Electron. Still open source.
Modern desktop API client. Local-first, AI-powered, cloud-synced. Under 30 MB RAM, no Electron. Free account required, sign up with email or GitHub.
Built with Rust. Under 30 MB RAM. No Electron. Free account, sign up with email or GitHub. Most API clients are Electron wrappers consuming hundreds of MB of RAM. Flux is different and the difference is obvious from the first request. Most API clients bundle a full Chromium engine and Node.js runtime. Flux is built with Tauri and Rust, a true native binary with no web runtime overhead. Other tools need third-party integrations for load testing and mocking. With Flux, both are native features , no extra installs, no Docker, no config files. Many API clients route your data through their cloud by default. Flux stores everything locally. A free account is required (email or GitHub), cloud sync…from fluxapi.dev

- NONous – Open-Source Agent Framework with Autonomous, SWE Agents, WebUI2024 · github.com · ▲155
Hello HN! The day has finally come to stop adding features and start sharing what I've been building the last 5-6 months. It's a bit of CrewAI, OpenDevon, LangFuse/Cloud all in one, providing devs who prefer TypeScript an integrated framework thats provides a lot out of the box to start experimenting and building agents with. It started after peeking at the LangChain docs a few times and never liking the example code. I began experimenting with automating a simple Jira request from the engineering team to add an index to one of our Google Spanner databases (for context I'm the…
- ASA self-hosted OAuth 2.0 server for authenticating AI agents and machineFeb 2026 · github.com · ▲6
MachineAuth is a self-hosted OAuth 2.0 server for authenticating AI agents and machines. What is an AI agent in this context? A software bot (like OpenCLAW, Claude Code, etc.) that makes API calls to access protected resources. Instead of sharing long-lived API keys, your agents can authenticate using OAuth 2.0 Client Credentials and receive short-lived JWT tokens. Why? No more sharing API keys Short-lived tokens (configurable) Easy credential rotation Industry-standard security

Hi HN, I’m the creator of Cordum. I’ve been working in DevOps and infrastructure for years (currently in the fintech/security space), and as I started playing with AI agents, I noticed a scary pattern. Most "safety" mechanisms rely on system prompts ("Please don't do X") or flimsy Python logic inside the agent itself. If we treat agents as autonomous employees, giving them root access and hoping they listen to instructions felt insane to me. I wanted a way to enforce hard constraints that the LLM cannot override, no matter how "jailbroken" it gets. So I built Cordum. It’s an open-source…

Hi HN. I'm the founder of Phoenix Labs (ex TikTok, Applied AI) and we're open sourcing our internal tooling today which is like a toolchain / meta-harness for CLI agents useful for really scaling eng and creative work. We are a very small team who's building a very ambitious product so we had to find ways to squeeze every ounce of efficiency that we could get our hands on. Harness strengths of different models (Claude, GPTs) and CLI-harnesses (Claude Code, Codex), safe/robust browser integration to speed up UX/QA testing, teams cli to speed up security reviews and parallelize…

Hello HN! I found that picking out plausible but diverse skin tones for my digital art and game development projects was kind of difficult, and I got curious about if there was a way to define a color space that made it easy. I've built a color picker and procedural generation algorithm based on the space as well as a bunch of other fun js features and demos throughout the page that use the equations. If you find it interesting, I have lots of explanations of how I built it and what properties the space has. The methodology might be a bit shaky, but hopefully the result is as helpful for…

I trained a 125M-parameter transformer to autocomplete piano performances in real time (~108 notes/sec on an iPhone 15). The idea is basically GitHub Copilot or Tabnine, except instead of prompting it with code, you prompt it by playing a few notes on a MIDI piano. The model then continues what you played, entirely on-device. The app is free if anyone wants to try it. Happy to answer questions about the model, training, Core ML, or the many things that didn't work.
