What changed, version by version

• Screenshots in a terminal. A screenshot on the clipboard (⌃⇧⌘4) pastes with ⌘V, and the screenshot tool's floating thumbnail, or an image dragged out of another app, can be dropped on a terminal. Suijin saves the image as a PNG in its caches folder and pastes the file's path, as it does for a file dropped from Finder, so Claude Code and Codex attach it. Saved images are removed after a week.
• Tabs by number. ⌘1 to ⌘8 select the tab at that position in the tab bar and ⌘9 selects the last tab, also while a terminal has the keyboard. Settings › Shortcuts lists them.
• Copy a code block. Every code block in the Markdown viewer has a copy button at its top corner; one click copies the whole block, including the part scrolled out of view.

The first release of Suijin: a native macOS app that runs Claude Code, Codex and any other command-line AI coding agent side by side, each in a git worktree of its own.

• Workspaces and worktrees. Add a git repository or a plain folder as a workspace. Each agent gets a worktree on a branch of its own, so parallel changes never collide, and the sidebar shows every worktree with the status of the sessions running in it.
• Tabs and split panes. Start Claude Code, Codex or a shell in a tab, and run any other command-line agent in the shell. A tab splits into as many as ten panes; drag a pane by its header to rearrange it, or zoom the one you are reading.
• Sessions that keep running. Sessions run in a background helper, so quitting or updating Suijin does not stop your agents. When an agent exits, its tab shows a Session Ended view with Resume Session and Start Again.
• Changes and pull requests. Review what an agent changed in a native diff viewer, leave notes on a file or a line and send them back to the agent, then commit, push and open the pull request from the same tab.
• Files and media. Code, rendered Markdown, images, video and audio open in a tab next to your sessions.
• Permission modes. Every Claude Code and Codex session starts in a permission mode: Ask, Auto-Accept Edits, Plan or Skip All Permissions for Claude Code; Ask, Auto, Read-Only or Skip All Permissions for Codex. Settings sets the default for each agent, and a session that skips permission checks is confirmed first and marked with a badge.
• Multiple accounts. Add several managed Claude and Codex accounts without touching your own logins, and see each plan's usage in the status bar. Continue With Another Account carries a conversation to another account when one runs out. Two options, off by default, move sessions for you when the default account changes or when an account hits a usage limit. Settings › Accounts notes that using several accounts this way may be against the provider's terms.
• Agent orchestration. Ask an agent for "Suijin workers" and it starts other Claude Code or Codex agents with the bundled suijin command, each in a tab of its own, answers their questions and collects their results. Ask it to stop a worker and it does (suijin worker stop): the worker's terminal ends and its tab closes by itself. Worker rows in the sidebar have a menu with Show Worker and Close Worker.
• Stats and usage. Settings › Stats & Usage shows tokens, estimated cost and activity per day from the local Claude Code and Codex logs, and the Resource Manager shows the memory and CPU of running sessions.
• Welcome tour. The first launch opens a short tour of workspaces, sessions, changes and accounts, with whole-window captures, hand-written notes and four water sprites that follow the pointer and answer a click. Help › Welcome to Suijin opens it again.
• Settings. Light, dark or automatic appearance, 15 terminal themes, a searchable list of every keyboard shortcut (⌘/), and a Permissions section that shows whether macOS allows notifications, the background helper and Full Disk Access, with a button to allow each and a Repair button when the background helper is not working. Settings › About links to the website, the source code, the community and the sponsor page.
• Updates. Suijin checks for a new version about once a day and installs it in place; Settings › General turns the automatic check off. suijin.app counts those checks per day and app version, and keeps nothing else.
• Private by design. No account, no telemetry and no crash reports. Your code and your agents stay on your Mac.
• Requirements. macOS 15 or later; the Liquid Glass interface needs macOS 26 or later. Suijin is signed with a Developer ID, notarized by Apple and open source under the Apache License 2.0.
