From Cursor to a Terminal Grid: A Migration Story

I used Cursor for roughly a year. I liked it. I recommended it to colleagues. Then I migrated to a terminal grid with Claude Code, Codex, and Qwen running in parallel panes, and I've been there for most of 2026. This is the honest write-up of why, what I miss, and what I don't.

This isn't a dunk on Cursor — it's a legitimate tool and a lot of people will stick with it happily. But if you're Cursor-curious-about-leaving, this is the migration I'd describe to a colleague over coffee.

What Cursor is good at

Credit where it's due. Cursor's core strengths, as I experienced them:

• Zero-friction editor-integrated AI. The suggestions are right there, no context switch. For a year that was enough.
• Excellent multi-file edits in the editor UI. Diff review in-place was genuinely great.
• Tab-completion and ghost-text style suggestions. The flow state of fast-typing with AI suggestions is real.
• Reasonable defaults. Out of the box it works well enough that you don't have to think about it.

For developers who want an IDE with AI baked in and don't want to tune a workflow, Cursor is a strong choice. Full stop.

Why I started looking

Two things pushed me:

Parallel work. My solo flow was getting bottlenecked on "one agent, one conversation, one file at a time." I wanted to run two or three agents in parallel — one implementing, one reviewing, one doing cleanup. Cursor wasn't built around that; every attempt felt like stretching the tool.

Model flexibility. I wanted Claude for architecture, Codex for fast implementation, Qwen for cheap backfill. Cursor supports multiple models but the mental model is "pick one at a time." I wanted three at once, in visible panes, always on.

Neither is a Cursor flaw. Cursor is built around a different workflow. But the workflow I wanted didn't fit inside the editor.

The switching cost

Real. I'll be honest about it. The first two weeks felt slow.

• My muscle memory was "Cmd+K for AI." In a grid I had to think about which pane.
• I didn't have my Cursor rules carried over as skills; I had to rewrite them.
• Diff review in a terminal pane felt primitive after Cursor's inline diffs.
• I missed the tab-completion for small edits — genuinely.

By week three, most of this faded. By week six, the old workflow felt slow. But the first two weeks were real friction.

What the grid setup looks like

My current setup: SpaceSpider with a 2x2 grid per project, configured as a "space":

• Pane 1: Claude Code (Opus or Sonnet, depending on task). This is where I plan.
• Pane 2: Codex CLI or a second Claude. This is where things get implemented.
• Pane 3: Qwen. This is where tests and boring migrations go.
• Pane 4: Shell. Git, curl, kubectl, whatever.

Each pane has its own cwd, often a git worktree. I can see all four at once. See the grid layouts docs and the getting-started guide for the setup specifics.

For the pattern that made the whole thing worthwhile, see the parallel AI coding workflow.

What I gained

Concrete gains, six months in:

• Actual parallelism. Two or three agents working simultaneously, visible, supervisable.
• Model freedom. Three different CLIs, three different strengths, running side by side.
• Cost control. Sonnet and Qwen carrying the mechanical load means my bill dropped even as I did more work. See cutting your AI coding bill in half.
• Workflow portability. My skills and context files live in the repo, not the editor. They work for anyone on the team with any CLI.
• Environment consistency. My terminal is my terminal; my editor is my editor. They don't fight over who owns the AI.

The parallelism alone justified the switch for me. Roughly doubled shipping speed on implementation-heavy weeks.

What I miss

Honest list:

• Inline diff review. Cursor's in-editor diff was nicer than terminal-based diff. I use git diff in the shell pane, which works but doesn't feel as good.
• Tab completion for small edits. Terminal CLIs don't offer the "type, see suggestion, tab" flow. I sometimes drop back to my editor for small surgical edits.
• Onboarding simplicity. Cursor is "install and go." A grid setup is more involved.
• The convenience of one thing. A grid is several tools. That's more to update, more to configure, more to think about.

None of these are dealbreakers. All are real.

What I didn't expect

Two things surprised me:

My editor got faster and lighter. Freed from carrying the AI, my Neovim setup simplified. No more AI plugin contention; no more extensions fighting for keystrokes. I went back to a near-vanilla config and I'm happier for it.

I'm more thoughtful about prompts. In Cursor, the AI is a keystroke away, so I'd throw half-formed prompts at it. In a grid with CLI-based agents, the prompt lives in the pane as a chat message — more deliberate, and I compose prompts better because I can see the conversation shape.

Neither was a goal of the migration; both were nice side effects.

The mental shift

The biggest change wasn't tooling. It was the mental model.

Cursor thinks: "the editor is the center; AI is a feature." Grid thinks: "the agents are the workflow; the editor is for review and manual edits." These are different workflows and which one fits you depends on how much of your code you want AI writing.

If AI is writing 30% of your code, Cursor's model is right. If AI is writing 70-80%, the editor-centric model becomes the bottleneck and the grid makes more sense.

I did not understand this when I started. It emerged over the migration.

Comparison

A concrete comparison of what the two setups are good at:

The grid wins on parallelism and flexibility. Cursor wins on single-file ergonomics and onboarding.

Who should stay on Cursor

If any of these apply, stay where you are:

• AI writes less than half your code and you want IDE-native convenience.
• You rarely run multiple agents in parallel.
• You value onboarding simplicity for your team.
• You like the inline-diff flow for review.

There's no shame in staying. The grid isn't universally better; it's better for a specific workflow.

Who should migrate

If any of these apply, consider it:

• You want to run multiple agents in parallel, routinely.
• You're juggling two or three CLIs already and wishing they were in one place.
• Your AI bill is creeping and you want model-per-pane cost control.
• You want workflow portability independent of editor.
• You're comfortable in terminals and don't need IDE-native AI features.

That's me, and that's most of the senior devs I've talked to who've made the switch.

The migration plan I'd give a friend

If you're moving, the least-painful path:

1. Install Claude Code, Codex, and your third CLI. Get each working alone first.
2. Install a grid terminal (SpaceSpider, or whatever you prefer).
3. Set up one project as a 2x2 space.
4. Port your Cursor rules to CLAUDE.md and a few starter skills. See the Claude Skills workflow.
5. Use the grid for one project for a week. Keep Cursor open for the others.
6. Decide if it's working. If yes, migrate the other projects. If no, roll back cleanly.

Don't migrate everything at once. The "parallel comparison" phase is useful, and the rollback is cheap if the grid doesn't click.

For getting the first space up, see getting started and the parallel AI agents use case.

Key takeaways

Migrating from Cursor to a terminal grid is a real workflow change, not a tool swap. The gains are parallelism, model flexibility, and cost control. The costs are inline-diff ergonomics, onboarding simplicity, and a couple weeks of muscle-memory rewiring.

For senior devs running multiple agents daily, the grid wins. For devs who want IDE-native AI with minimum friction, Cursor is still a reasonable home. Pick based on your workflow, not your tool loyalty. Try both for a week and your hands will tell you which one fits.
