Epho▲156Hey folks, Burak here. Epho is an API that allows running Claude Code, Codex or Opencode in a sandbox in the cloud. It abstracts away sandboxes, and allows running coding agents with a single HTTP request. Epho came out of our own struggles with building our own AI analyst: - Sandboxes give you bare machines; you need to configure them for agentic workloads. - Each agent behaves differently, and you need to build integrations with each of them. - Sandbox providers are not very reliable, which means you need to figure out a multi-provider strategy to avoid failures. - Logging, artifacts,…

I don't always all-caps, but when I do, it's because every word is an acronym. The NASA HORIZONS[1] system is a telnet service that provides planetary data and ephemeris tables, which are basically coordinate-time plots for celestial bodies. It's pretty archaic and somewhat difficult to use, especially since it just dumps out text tables and you have to parse it to do anything with it. Some projects, e.g. KDE Marble, use it as a data source and typically just consume it with a little procedural code to get what they need. I wanted to provide a full-fledged library for it so that you can…

Hey HN, I'm Saai, one of the creators of Sylix. I made this open-minded version of Cursor where you can get all of the core features of Cursor but in a fully customizable IDE (Ctrl+K, @docs, parallel agents). We love Cursor so much, but there are so many other features we're building, including all things like multi-edit, parallel swaps, agent indexing (but not the traditional one), parallel LSP, or maybe... we might give agents a better understanding of the codebase via multi-semantic memory instead, alongside in-search grep for your system files or workspace. Sylix will be open source once…

Hey HN, I built browser-use, an open-source alternative to OpenAI’s Operator for browser-use systems, and here’s why I think it’s better: Flexibility: You can use any LLM with our tool – Gemini, Anthropic, Qwen, Llama, DeepSeek, and more. As new models improve, so does your agent. Open Source: No need to pay $200/month or endure long waitlists – it’s free and accessible to everyone today. Custom Automation: Our Python package allows you to build actual web automations. Your LLM can gain new tools, like file uploads. Cost: Our system is 30x cheaper than Operator, e.g., when used with…

Hello HN! My name is Rémy and I recently published an astronomy dashboard where everything is open source: the code of the website, the framework it is based on and the library that computes astronomical data. For the last few years, I have been developing the Ruby library Astronoby (https://github.com/rhannequin/astronoby) with as much dedication and perseverance I could while I don't have any scientific academic background. My end goal was to use this library and build a website that not only provides as much data as possible, but let anyone access and understand how it…
