• Browser Skill Toolbar — Quick-access menu in the browser toolbar to install and use the browser automation skill.

• Default Browser Setting — Choose to open all URLs in the built-in browser, your system default, or any installed browser like Chrome or Firefox. Built-in is now the default, so links from terminals, markdown, and menus open right inside the editor.

• Reduced editor and terminal stability issues with additional safety hardening across crash-prone paths.

Requirements

• macOS 14.0 (Sonoma) or later

Agentastic.dev v0.5.18

Made a lot of improvements to make the app more stable and smoother. If the app is crashing on your mac please ping me or make some noise 💜

Highlights

• Kanban Board — A brand-new Kanban view organizes your worktrees into columns by label. Drag and drop cards between columns to reassign labels, reorder columns, and click any card to jump straight to that worktree. Access it from the View menu (⇧⌘J) or the Command Palette.

• PR & MR Status Badges — See pull request and merge request status directly in the worktree navigator. Supports GitHub, GitLab, and Bitbucket with clickable badges, CI status indicators, and color-coded review states. No more switching to your browser to check PR status.

• New App Icon — Agentastic has a fresh new look with the mechanical ghost blueprint logo across all build variants.

Improvements

• Quick Setup option: You can globally set which files get copied to your worktree during setup (Settings > Worktree).
• Side-by-side diff view is now the default for new users, with diagonal hatching on empty columns for a cleaner visual distinction between additions and deletions.
• Full-width diffs for new and deleted files — when viewing a newly added or fully removed file in split mode, the content now expands to use the full width instead of showing an empty column.
• Per-file collapse controls in the diff viewer — quickly collapse or expand individual files in a diff with a single click on the chevron in each file header.
• Zen Mode overlay navigator — hovering near the left edge now reveals the navigator as an overlay, keeping your terminal and editor layout stable instead of resizing them.
• Label selector in Agent Home — pick a label when creating new worktrees so they're organized from the start.
• Quick Setup for new worktrees — configure global quick-setup paths (files or directories) that are automatically copied into every new worktree during creation.
• Termination diagnostics — detailed process-safe logging helps diagnose unexpected shutdowns, with automatic log rotation to keep things tidy.

Bug Fixes

• Stability and performance improvements across the board.
• Fixed a crash caused by SwiftUI layout recursion when creating a new agent from the context menu in multi-repo workspaces.
• Fixed a silent exit(1) crash triggered by nil Picker selections and state mutation cascades in Agent Home.
• Fixed syntax highlighting briefly disappearing when switching focus between the editor and terminal.
• Session recovery now persists open workspaces every 30 seconds, so your session is restored even after an unexpected crash.

Requirements

• macOS 14.0 (Sonoma) or later
• Apple Silicon or Intel processor

Agentastic.dev v0.5

Dev 0.5 is available today. This version brings a slew of new features and usability improvements.

Features

• Containers - This was the most-requested feature since our beta launch. Docker containers are now supported, so you can use them in addition to the worktrees for full isolation. (requires Docker Desktop)
• Multiple Git Repos in the same workspace - The 2nd most requested feature. You can now open multiple git repos in the same workspace and seamlessly work/switch between them.
• Pinned agents - You can pin a running agent, and it will keep it up at the top. You can pick accent colors for the repo as well.
• Notifications - Agents now show an orange badge when they are waiting for something. Under the hood this is coded as when any terminal emits echo -e "\n", or creates a .agentastic/waiting signal, we show the badge. You can also include that in your build scripts to know when a build is finished (e.g., trap ...)
• Zen mode - This turns to a pure terminal experience. You can still hover over the left edge to open the agent panel.
• Open In... - We get that you might want to open your agent's workspace in other editors or IDEs. I'm not saying you should, but if you really want that, now you can. Ok, enough. Come back... Come back to me!
• Various bugfixes and quality of life improvements
