Comparison
Nimbalyst vs Vibe Kanban
Nimbalyst is an open-source visual workspace that runs Claude Code and OpenAI Codex side by side, with pluggable agent harnesses. Vibe Kanban is a focused CLI and local web kanban for parallel coding agents, originally built by Bloop and now community-maintained under Apache 2.0. Both help teams manage many agents at once. Vibe Kanban is the better fit when you only want a focused board. Nimbalyst is the better fit when the board needs to sit inside a broader workspace for planning, visual artifacts, code review, and mobile follow-up.
Why People Switch
Why people switch from Vibe Kanban
We want the board plus the workspace
Vibe Kanban is strong when the board is the product. Once work includes docs, mockups, diagrams, schemas, and code review in the same project, a larger workspace becomes more useful.
We want richer planning artifacts
Vibe Kanban plans around issues, sub-issues, and board state. Nimbalyst also supports plan documents and tracker items that stay attached to the execution flow.
We want active commercial development
Vibe Kanban continued as a community-maintained Apache 2.0 project after Bloop's April 10, 2026 shutdown announcement. Nimbalyst has a full-time team shipping the product commercially.
We want mobile review
Nimbalyst has a native iOS app for checking sessions, reading transcripts, and approving changes. Vibe Kanban does not have a native mobile companion.
We want heterogeneous agents by default
Both tools support multiple agent harnesses. Nimbalyst makes the Claude Code plus Codex workflow central to the product instead of a secondary setup choice.
Overview
Two tools, different approaches
Nimbalyst
Nimbalyst is an open-source visual workspace that runs Claude Code and OpenAI Codex side by side, with pluggable agent harnesses. It includes a session kanban, planning and task tracking, visual editors for markdown, mockups, diagrams, and data models, a Monaco-based code editor, git worktree integration, and an iOS companion app. The desktop and iOS apps are MIT licensed.
Vibe Kanban
Vibe Kanban is a focused open-source kanban and review workflow for coding agents. Bloop launched it in June 2025 as a CLI plus local web UI for planning issues, assigning agent work, watching transcripts, and reviewing diffs. After Bloop's April 10, 2026 shutdown announcement, the project continued as an Apache 2.0 community-maintained, local-first tool.

Side-by-side breakdown
Nimbalyst Advantages
Where Nimbalyst shines
A multi-agent workspace, not only a board
Claude Code and Codex sessions appear on the same Nimbalyst board, but the board is only one layer. Plans, files, diffs, and artifacts live in the same workspace.
Visual artifacts agents can create and we can review
Mockups, diagrams, and data models live next to code in the project tree. Agents can generate them, and we can review them without leaving the product.
Planning that reaches into execution
Plan documents and tracker items feed the kanban directly. Specs, tasks, and execution stay in one system instead of splitting across a planning tool and an agent board.
Mobile session review
The Nimbalyst iOS app shows live agent transcripts, file changes, and approval prompts, so we can review work from a phone when the laptop is closed.
Honest Assessment
Where Vibe Kanban is stronger
Focused and lightweight
Vibe Kanban stays close to one job: planning and reviewing parallel coding-agent work on a board.
CLI-first workflow
A CLI plus local web UI fits teams that live in the terminal and do not want a larger desktop workspace.
Strong issue-board loop
Issues, sub-issues, transcript watching, and diff review form a coherent flow for agent task management.
Community-maintained Apache 2.0 project
Teams that prioritize permissive licensing and are comfortable with community maintenance may prefer that shape.
Recommendation
Who should use which
Choose Nimbalyst if…
We want the agent kanban as one part of a larger multi-agent workspace, with planning, visual editors, code review, and mobile access in the same product. We want Claude Code and Codex side by side by default, and we want a heterogeneous harness model to be a core part of the product.
Choose Vibe Kanban if…
We want a focused CLI and web kanban for parallel agents, and most of our planning can stay at the issue-and-board level. We already like the rest of our tooling and are comfortable depending on a community-maintained project.
