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 mermaid diagrams, text, tables, mockups, and images in standard markdown for human/AI context

- Iterate on html mockups with Claude Code, annotating the mockups, and then use them as context for people and Claude Code coding

- Tie sessions to documents to sessions, find and resume sessions, treat sessions as context, run parallel sessions

- Code with Claude Code with all of this context, use / commands, see git status

Nimbalyst is in Beta, local, and free. We would love your feedback.
