We'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…

Hi, I'm Karl. Greg and I spent the last year building Nimbalyst, an open-source local desktop workspace for working with coding agents.

So we integrated: - Visual editors for markdown, diagrams, mockups, data models, CSV, code, and your own custom extensions - Red/green diff review with per-block accept/reject when an agent makes changes - Session manager with…

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…
