The lay of the land
- **Cursor** — chat-first IDE, VSCode fork, best at multi-file edits and quick refactors.
- **Claude Code** — CLI-first agent, best at long-horizon tasks and headless CI use.
- **Warp** — agentic terminal, best at debugging failing builds and shell one-liners.
Most senior developers I know run at least two of them.
When to reach for each
Cursor shines when you're editing. Cmd-K to inline-refactor a function, tab-complete for boilerplate, the composer for cross-file changes. Its indexing understands your monorepo. The Auto model routing keeps costs sane.
Claude Code shines when you're delegating. Long-horizon tasks like "add MFA to this app" work in a way they don't in Cursor — you can walk away for 10 minutes. Extended-thinking mode plans multi-step changes rigorously. Runs headless in CI as claude -p "...".
Warp shines in the shell. Debugging test failures, reading logs, guessing at broken deploys. Its agent has full shell + file context and asks before running destructive commands.
Combining them
The strongest pattern is: 1. Warp for shell + debug — always running in a terminal pane. 2. Cursor for editing — active window during a coding session. 3. Claude Code for delegated tasks — spawned from Warp for the big ones, catches in CI.
You'll pay for three subscriptions but get 10x back in time.
What each one gets wrong
- Cursor sometimes over-eagerly rewrites code you didn't ask it to touch. Turn off "auto-edit on save" if it burns you.
- Claude Code can loop on flaky tests — pin a max-turns flag.
- Warp's agent has occasional shell-safety false-positives — the "requires approval" prompt fires on genuinely safe commands.
