Nimbalyst is an open source workspace for product people who work with coding agents. Write the plan, hand it to Claude Code or Codex, and read the changes that come back, all in one app.
Markdown docs, mockups, diagrams, and a tracker, in one workspace rather than four tools.
Point an agent at the plan and watch it work. Several can run at once, each isolated in its own branch.
Every edit shows up as a visual diff you can accept or reject. No terminal required to follow along.
Nimbalyst sends its outbound email from usenimbalyst.com so that support and account mail on nimbalyst.com stays separate. Mail from here is written by Karl Wirth, who builds Nimbalyst.
Reply to that email to opt out and you will not hear from us again. You can also mail karl@usenimbalyst.com at any time.
