Key capabilities

Parallel Claude Code and Codex sessions organized on a kanban board

One-click git worktree isolation per session; inline diff review of file changes

Visual editors (markdown, CSV, code, Excalidraw, Mermaid) plus an iOS monitoring app

Desktop apps for macOS / Windows / Linux; MIT licensed, free for individuals

Practical fit

Nimbalyst fits people who want a visual kanban-and-worktree environment for parallel Codex and Claude Code sessions, with file review and editors in the same workspace. It is the active successor named by Crystal, making it the relevant starting point for a new comparison.

Its breadth can be helpful for mixed work, but alpha agent integrations and one-click workflows still need a deliberate trial. The adoption question is whether visibility and review improve enough to justify another desktop layer.

How to evaluate it

Which supported agents are stable enough for the team's normal work?

Can reviewers follow changes across sessions without losing repository context?

How are worktrees, local data, and the monitoring app secured and cleaned up?

Example decision

Create a small kanban board for two independent tasks, compare Codex and Claude Code sessions in separate worktrees, and review every changed file before manually merging either branch.

Verify before you adopt it

Check the current desktop releases, supported platforms, and alpha integration notes.

Review the MIT license and local-data behavior.

Test worktree cleanup and editor compatibility on a disposable project.

Best for

Parallel Claude Code and Codex sessions

Kanban + worktree workflow

Risk notes

Keep a human review gate before merge.

OpenCode and Copilot support are in alpha.

This is a community project. Verify maturity, licensing, permissions, and safety behavior before relying on it in production.
