Nimbalyst Beta
Hello Hacker News. The four of us have been getting the best results with Claude Code when we iterate with it to build full context and then use and update that context as we work. So, we built Nimbalyst to maximize our (and your) ability to iterate and build context with and for AI. Nimbalyst is the local WYSIWYG editor and session manager where you iterate with Claude Code on docs, diagrams, mockups, and code. Nimbalyst lets you: - Use all the power of Claude Code in a UI - Work with Claude Code to write and edit WYSIWYG markdown, see AI changes as red/green, approve them - Integrate…

What it does
You get the best results with Claude Code when you iterate with it to build full context. Nimbalyst is the local editor and session manager where you iterate with Claude Code on WYSIWYG markdown docs, mockups, diagrams, and code. This is the launch of Nimbalyst's Beta.
Nimbalyst is the visual editor and full-context workspace for Claude Code and Codex. Run parallel sessions, edit tasks, docs, diagrams, mockups, and code, and review every AI change. Free, open source.
Free for individuals. Works with your existing Claude Code or Codex subscription or API key. Use all your context without switching applications. Review AI changes. Approve, reject, edit, iterate. Edit Markdown files while Claude Code and Codex understands the full project structure, related files, and intent. Work directly in your markdown while interacting with Claude Code and Codex in parallel — no context switching. See which files the agent reads or edits, review changes instantly, and stay in full control of every update. Edit CSV data in a familiar spreadsheet view while Claude Code and Codex understands the structure and context of your data. Ask Claude Code and Codex to filter,…from nimbalyst.com

Nimbalyst open-source visual workspace for ClaudeCode, Codex, OpenCodeApr 2026 · github.com · ▲8We're open sourcing Nimbalyst, a multi-agent, visual workspace for building with Claude Code, Codex, and Opencode (alpha). It pairs parallel session management with WYSIWYG editors so you and your agents can work on the same files at the same time. The core idea: agents edit files, you edit files, and Nimbalyst makes that collaboration legible. Built-in WYSIWYG editors cover markdown, mockups, Excalidraw diagrams, data models, spreadsheets, and code (Monaco). Every edit is tracked back to the session that made it, with red/green WYSIWYG markdown diffs for review and approval. A session…
1CodeJan 2026 · github.com · ▲569Just to clarify the background a bit. This project wasn’t planned as a big standalone release at first. On January 16, Ollama added support for an Anthropic-compatible API, and I was curious how far this could be pushed in practice. I decided to try plugging local Ollama models directly into a Claude Code-style workflow and see if it would actually work end to end. Here is the release note from Ollama that made this possible: https://ollama.com/blog/claude Technically, what I do is pretty straightforward: - Detect which local models are available in Ollama. - When…
NimbusMay 2026 · usenimbus.app · ▲89Hi HN, I'm Anil. Nimbus is a desktop browser with an AI agent built into it. The UX is shamelessly inspired by Claude Code: a chat bar at the bottom, an agent log above it, and the webpage itself when its needed. This is mainly a UX experiment for me. And also the reason it isn't a Chrome extension: once you have a chat bar that understands intent, the URL field is redundant. You shouldn't have two places to tell the browser what you want. I didn't want to bolt an agent onto an existing browser's chrome and end up with duplicated controls everywhere — I wanted full freedom to redesign the…

Talanoa▲340Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…

Community, All the HN belong to you. This is an archive of hacker news that fits in your browser. When I made HN Made of Primes I realized I could probably do this offline sqlite/wasm thing with the whole GBs of archive. The whole dataset. So I tried it, and this is it. Have Hacker News on your device. Go to this repo (https://github.com/DOSAYGO-STUDIO/HackerBook): you can download it. Big Query -> ETL -> npx serve docs - that's it. 20 years of HN arguments and beauty, can be yours forever. So they'll never die. Ever. It's the unkillable static archive of HN and it's…
