SpaceSpider vs Windows Terminal

SpaceSpider is a Tauri 2 desktop app that runs a full-screen grid of real PTY panes with one AI coding CLI per pane. On Windows it spawns each pane through ConPTY via portable-pty, so every AI CLI behaves exactly like it would in PowerShell or Windows Terminal. You pick a directory, pick a grid preset of 1 to 9 panes, and assign Claude Code, Codex, Qwen Code, Kimi CLI, or a shell to each cell.

Windows Terminal is Microsoft's modern terminal emulator for Windows 10 and 11. It runs any shell you like (PowerShell, WSL distros, cmd, Git Bash), supports tabs and splits, has a rich JSON settings file, and integrates with the Windows shell for right-click open-here and jump lists. It is the default answer for developers who want a capable terminal on Windows without leaving the Microsoft ecosystem.

TL;DR

• Windows Terminal wins on shell flexibility, deep Windows integration, and unlimited tabs and splits.
• SpaceSpider wins on a pre-built AI grid, per-space cwd, and a dedicated window sized for multi-agent reading.
• Both use ConPTY under the hood; compatibility with Windows CLIs is the same.
• Pick Windows Terminal as your general terminal; pick SpaceSpider for the AI-grid workflow.

Where Windows Terminal wins

• Shell flexibility. Windows Terminal runs PowerShell, pwsh, cmd, any WSL distro, Git Bash, or a custom profile pointing at any executable. Adding a new shell is a few lines of JSON. SpaceSpider panes run one of the catalog CLIs or a shell; anything beyond that is outside the wizard.
• Native Windows integration. Jump lists, Windows Terminal as the default, right-click open in Terminal from File Explorer, dynamic profiles for installed WSL distros, Azure Cloud Shell tab. SpaceSpider does not hook into any of that.
• Unlimited layout freedom. You can split any pane, close any split, resize splits with the mouse, and move panes between tabs. SpaceSpider's grid is fixed to the preset you picked when creating the space.
• wt.exe command line. You can launch Windows Terminal with a specific split layout from a shortcut or script. SpaceSpider has no equivalent external entry point.
• Active ecosystem. Themes, color schemes, oh-my-posh, Nerd Fonts, and fragment extensions are all well-supported. SpaceSpider is a young app with no plugin system.

Where SpaceSpider wins

• AI CLI catalog. SpaceSpider ships knowing which AI coding CLIs exist, detects which are installed on your PATH, and offers an install hint when one is missing. In Windows Terminal you paste commands in panes yourself and remember which profile corresponds to which AI CLI.
• Project-scoped spaces. SpaceSpider's spaces are directory plus grid. Every pane inherits the cwd, which matters when you run several AI agents against one repo. In Windows Terminal you set startingDirectory per profile or type cd in each pane.
• Grid sized for reading multiple agents. The presets of 2, 4, 6, and 9 are sized for reading many panes at once. Windows Terminal splits are flexible but you size them yourself.
• Restart a full workspace in one click. Opening a space respawns every configured pane with the right CLI and cwd. Windows Terminal can restore tabs but pane topology and per-pane commands take more work.
• Linux parity. SpaceSpider runs the same way on Linux. Windows Terminal does not.

When to pick Windows Terminal

• You want a general-purpose terminal for every shell you use, not just AI CLIs.
• You live in PowerShell, WSL, and cmd across many profiles.
• You value unlimited tabs and flexible splits over a fixed grid.
• You already have a finely tuned settings.json you do not want to abandon.
• You are happy to run AI CLIs in whichever pane you happen to have open.

When to pick SpaceSpider

• Your core workflow is running Claude Code, Codex, Qwen, or Kimi in parallel on one repo.
• You want to click a space card and have four AI agents on screen in seconds.
• You want a signed installer that auto-updates and does not depend on the Microsoft Store.
• You are on both Windows and Linux and want the same grid on both.
• You are tired of retyping cd repo && claude in every pane.

Can you use both?

Yes, and most Windows developers will. Windows Terminal stays the default for your daily shell, ssh sessions, and WSL. SpaceSpider is what you open when you specifically want a multi-agent grid. Because both use ConPTY under the hood, any CLI that works in one works in the other with identical behaviour.

You can even launch SpaceSpider from a Windows Terminal command or the Start menu and keep WT open for general shell work. There is no conflict between the two.

FAQ

Does SpaceSpider run on top of Windows Terminal?

No. SpaceSpider ships its own rendering (xterm.js inside a Tauri WebView) and spawns PTYs directly via ConPTY. It does not embed Windows Terminal and does not require it.

Do my PowerShell profile and aliases work in SpaceSpider panes?

Yes. When you put a shell in a pane or any CLI that runs inside a shell, it picks up your profile the same way PowerShell launched from Windows Terminal does. ConPTY is the same underlying surface.

Can I set a custom command in a SpaceSpider pane, not just catalog CLIs?

You can pick "Shell" for a pane and run any command inside it. The catalog tiles for Claude Code, Codex, Qwen Code, and Kimi CLI are convenience entries; shells are fully general.
