Cursor and Windsurf are AI-powered code editors (VS Code forks) with built-in agents. Pane is not an IDE — it's an agent manager that runs any CLI agent in parallel and leaves your editor alone. They solve different problems. Starting June 15, 2026, there's a new cost difference too: Cursor and Windsurf route Claude through Anthropic's API, so BYOK keys draw from a new programmatic credit pool ($20/mo on Pro). Pane spawns the local claude CLI - interactive usage, your sub keeps working.
| pane | cursor | windsurf | |
|---|---|---|---|
| category | agent manager | AI IDE | AI IDE |
| claude subscription | uses your existing pro/max sub | no - API-based, hits new $20/mo programmatic cap | no - API-based, hits new $20/mo programmatic cap |
| agents | any CLI agent (claude code, codex, aider, goose, anything) | cursor's built-in agent only | windsurf's cascade agent only |
| parallel agents | yes — unlimited panes, each isolated | no | no |
| git worktrees | automatic per pane | manual | manual |
| code editor | none — use your own (VS Code, Neovim, JetBrains, etc.) | built-in (VS Code fork) | built-in (VS Code fork) |
| lock-in | none — any agent, any editor, any OS | cursor's editor + agent | windsurf's editor + agent |
| open source | yes (AGPL-3.0) | no | no |
| pricing | free | $20/mo+ | $15/mo+ |
pane is not an IDE
Cursor and Windsurf replace your code editor. Pane doesn't. Pane sits alongside your editor — it manages the agents that write code while you review diffs and manage git. You keep using VS Code, Neovim, JetBrains, or whatever you prefer.
pane doesn't lock you into one agent
You can't run Claude Code inside Cursor. You can't run Aider inside Windsurf. These IDEs lock you into their built-in agent. Pane runs any CLI agent — Claude Code, Codex, Aider, Goose, or whatever ships tomorrow. No lock-in.
pane runs agents in parallel
Cursor and Windsurf run one agent session at a time. Pane runs unlimited agents in parallel, each in its own git worktree, each fully isolated. Work on five features simultaneously. Agents never step on each other.
you can use pane with cursor or windsurf
Pane and agentic IDEs aren't mutually exclusive. Many developers use Pane to orchestrate CLI agents (Claude Code, Codex) while keeping their IDE open for editing. Pane manages the parallel workflows. Your editor is for reading and writing code.
scenario: a typical heavy day of agent-driven coding - around 2M Claude Sonnet tokens at a 70/30 input/output mix.
At Anthropic's list rates ($3/MTok input, $15/MTok output), that's roughly $13/day in API spend.
cursor pro + BYOK claude key: $20/mo for Cursor, plus API spend through your key. After June 15, the BYOK key draws from the new programmatic credit pool ($20 on Pro, $100 on Max5x, $200 on Max20x). At $13/day, the Pro pool lasts ~1.5 days. After that: pay-as-you-go API rates on top of the Cursor sub.
pane + claude pro/max: $0 on top of your existing sub. Pane runs the local claude CLI in a terminal pane - that's interactive usage, unaffected by the June 15 split. Your Pro/Max sub keeps working the way it did yesterday.
Token estimate is illustrative - your real usage varies. The structural point holds: API-routed tools hit the new cap, terminal-spawned ones don't. full breakdown by tool →
use cursor or windsurf if you want AI built into your editor for autocomplete, inline suggestions, and single-session agent chat while you code.
use pane if you want to run multiple AI agents in parallel on different tasks, review their work, and manage git — without being locked into one agent or one editor.
use both if you want the best of both worlds — an IDE for writing code and Pane for orchestrating agents.
