Hello Product Hunt! We are Karl, Greg, Jordan, and Q, the founders and some of the key team behind Evergage which Salesforce bought in 2020.
Nimbalyst is in Beta, local, free, but not open source. We would love to discuss it here with you and have you try it and give us feedback.
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 maximize our (and your) ability to iterate and build context:
Work with Claude Code to write/edit WYSIWYG markdown. Approve AI changes
Annotate the mockups, iterate on html mockups with Claude Code,
Tie sessions to documents, resume sessions, run in parallel
Code with Claude Code
We love this product and are proud of it. We use Nimbalyst to build Nimbalyst, one of us as Product Manager/Marketer/Biz person and the others as developers.
We are excited to show it to the Product Hunt community and, again, we would love your feedback and ideas.
