Why We Use Cursor for Refactors, Windsurf for Cascade, and Claude Code for Architecture — The 3-Tool Rotation That Replaced Loyalty
Cursor Composer loses context at 90 minutes. Windsurf Cascade holds it longer but lacks LSP. Claude Code Routines are infrastructure. We rotate all three — here's the decision matrix we use daily.

Why We Use Cursor for Refactors, Windsurf for Cascade, and Claude Code for Architecture — The 3-Tool Rotation That Replaced Loyalty
TL;DR: No single AI editor wins every workflow. Cursor wins <90-min TypeScript refactors (LSP), Windsurf Cascade wins multi-hour agentic sessions, Claude Code wins greenfield architecture + verification loops. We rotate daily — here’s the exact decision matrix. Full comparison →
The Context
Two-dev team, 6–8 hrs/day AI-assisted coding. January–May 2026: Cursor Pro daily driver. June 2026: Context loss incidents (Cursor 90-min ceiling), Copilot pricing pivot,Claude Code credit pool launch forced re-evaluation. Tested all three side-by-side on identical tasks: 14-file Stripe migration, new API endpoint, Supabase schema change.
What We Tested
| Tool | Use Case | Verdict | Why |
|---|---|---|---|
| Cursor Composer | 14-file Stripe migration (2.5 hrs) | ❌ | Lost stripe listen tunnel + Supabase 2×; 45 min recovery |
| Cursor Composer | <90-min TypeScript refactor | ✅ | LSP catches type errors mid-edit; fastest for type-heavy work |
| Windsurf Cascade | Same 14-file migration (2.5 hrs) | ✅ | Persisted terminal state entire session; zero context loss |
| Windsurf Cascade | Multi-hour agentic debugging | ✅ | Cascade agents maintain context 4+ hrs; good for exploratory work |
| Claude Code | Greenfield API + test loop | ✅ | Terminal-native; cc --allowedTools runs autonomous verify-fix |
| Claude Code | Long refactor needing IDE context | ⚠️ | No LSP; misses type errors until test run |
The Pivot Point
May 15, 2026 (Cursor context loss during Stripe migration) → May 20 (tested Windsurf Cascade on same task, zero loss) → June 8 (Claude Code greenfield autonomy). Three different tools won three different workflows. Loyalty to one editor became the anti-pattern.
What We Use Now
Daily Decision Matrix (pinned in team Notion):
| If the task is… | Use… | Because… |
|---|---|---|
| TypeScript refactor, <90 min, LSP-critical | Cursor | Catches type Error mid-keystroke; Composer fast |
| Multi-hour migration/debugging, terminal state critical | Windsurf | Cascade persists PIDs, DB connections, server state 4+ hrs |
| Greenfield feature, needs test-fix loop, verification | Claude Code | cc --allowedTools runs autonomous; Routines reusable |
| Inline completions only | Copilot | Fastest tab-completion; $19/mo predictable |
| Privacy-sensitive / offline | Ollama (qwen2.5-coder:7b) | Zero cost; local only |
Team Aliases (shared dotfiles):
alias cur='cursor-timer' # 90-min hard limit
alias ws='windsurf'
alias cc='claude-code'
alias cx='codex' # backup for 5+ hr sessionsWhen You’d Choose Differently
- Solo dev, one tool max: Windsurf ($15) balances persistence + IDE integration best.
- Enterprise SSO/SAML required: Cursor Business ($40) has admin controls; Windsurf/Anthropic lag.
- Git-native workflow: Aider (terminal, BYOK) or Claude Code with git hooks.
Tool Crucible Rating
| Dimension | Cursor | Windsurf | Claude Code |
|---|---|---|---|
| Overall | 3.5 | 4 | 4.5 |
| Ease of Use | 4 | 3.5 | 3 |
| Context Persistence | 2 (90-min cap) | 5 (4+ hrs) | 3 (session only) |
| Verification Loops | 2 | 3 | 5 |
| Value | 3 ($20 + 2nd tool needed) | 4 ($15 flat) | 5 ($100 pool = heavy usage) |
