Local WYSIWYG Markdown, mockup, data model editor powered by Claude Code

We 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 be the local WYSIWYG editor and session manager where you iterate with Claude Code on markdown docs, diagrams, mockups, data-models, sessions, and code. Nimbalyst lets you:

- Work in one integrated tool leveraging all your context.

- 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

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

- Build your data models based on your docs/code, iterate on them with Claude Code, export them in standard formats.

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

- 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.

Really cool! Switched out my default terminal to this and am using it for the last half an hour. Posted a few feedback comments. Looking forward to it developing more :)

Thank you! I am reviewing your comments in app and will get back to you soon by email. Please keep them coming!

I like that I can see the changes in rendered markdown instead of having to view them plaintext

Thanks. We built a first class WYSIWYG markdown editor integrated with Claude Code.
