Baton is a native desktop orchestration tool for running multiple AI coding agents in parallel — each in its own isolated git worktree. Built for developers who want to run Claude Code, Gemini CLI, or OpenAI Codex CLI simultaneously without agents overwriting each other's work. The key insight is elegant: git worktrees let you check out the same repo to multiple directories, each on its own branch. Baton makes this trivial — auto-generating branch names and workspace titles with AI, surfacing notification badges when agents finish or hit errors, and letting you toggle "Accept Edits" mode per workspace independently. At $49 one-time with no subscription, Baton is aimed squarely at developers who find single-agent coding frustrating and want to run multiple tasks concurrently. The free tier caps at 4 concurrent workspaces. It's available for Mac, Windows, and Linux.

Pretty Fish is a free, open-source Mermaid diagram editor with live preview, 5 built-in themes, multi-page workspaces, and one-click SVG/PNG export. It works offline as a Progressive Web App (PWA) and requires no account, no login, and no installation. It supports all 14+ Mermaid diagram types including flowcharts, sequence diagrams, Gantt charts, entity-relationship diagrams, and Git graphs. The editor includes syntax highlighting, auto-completion, instant error feedback, and a clean split-pane layout. The multi-page workspace lets you manage entire diagram projects in a single session. Export quality is excellent — SVG output is clean and scaling-ready for use in presentations, docs, or design systems. Pretty Fish hit Hacker News front page today with 128 points and has the makings of the go-to Mermaid editor for developers who generate diagrams from AI-assisted documentation workflows. With LLMs increasingly generating Mermaid syntax in their outputs, having a polished renderer and editor matters more than ever.
Reviewer scorecard
“This is the workflow tool I didn't know I needed. Running three Claude Code instances on different features simultaneously, each in isolation, feels like having a real team. The worktree isolation means no constant merge conflicts — and getting notified when agents finish is genuinely delightful.”
“The official Mermaid live editor is clunky and slow. Pretty Fish loads instantly, works offline, and the multi-page workspace means I can manage all my architecture diagrams in one place. Bookmarking this immediately as my default Mermaid editor.”
“It's a GUI wrapper around git worktrees and process management — most of what Baton does can be scripted in bash in an afternoon. The $49 price is reasonable but the moat is thin. Expect this to become a built-in feature of Cursor or Windsurf within a release cycle.”
“It's a genuinely nice editor but it's solving a niche problem — most devs who need Mermaid diagrams already use VS Code extensions or embed them in Notion. And with no backend, there's no collaboration or sharing story, which limits its use in team workflows.”
“Parallel agent orchestration at the desktop level is the first step toward autonomous software teams. Baton is primitive, but the pattern it establishes — isolated worktrees, parallel execution, async notification — is exactly how future dev environments will work. Get comfortable with the paradigm now.”
“As AI tools increasingly output Mermaid syntax to explain architectures and flows, the need for a great rendering environment grows. Pretty Fish positions itself at the intersection of AI-generated diagrams and human editing — that's a well-timed niche.”
“For non-developers using AI coding tools, Baton removes a lot of the confusion about why agents interfere with each other. The UX is clean enough that even designers who occasionally vibe-code can manage multiple tasks at once without losing their minds.”
“Five beautiful themes and clean SVG exports mean I can finally use Mermaid diagrams in client-facing presentations without them looking like developer scratch notes. This is the Mermaid editor I've always wanted and the zero-friction setup seals it.”
