Why We Dropped Copilot for Cursor — Then Nearly Quit Cursor Over Autonomy
Copilot's pricing broke us; Cursor's unasked database migration broke our trust. Here's how we configure Cursor safely and when we still reach for Cline instead.

Why We Dropped Copilot for Cursor — Then Nearly Quit Cursor Over Autonomy
TL;DR: Copilot’s 4x billing drove us to Cursor, but Cursor 3.0’s agent autonomy (unprompted DB migrations, file deletions) caused data loss risk. We now run Cursor with auto-apply disabled and use Cline for high-stakes refactors. Full comparison →
The Context
Two-dev team maintaining a Next.js/Postgres SaaS. Fled Copilot in April 2026 after billing chaos. Cursor felt like the answer — familiar VS Code fork, strong agent modes. Then a fresh Cursor install ran an unasked Prisma migration on our local dev DB, wiping seed data. First-time user uninstalled same day. We had to decide: configure Cursor defensively or migrate again.
What We Tested
| Tool | Use Case | Verdict | Why |
|---|---|---|---|
| GitHub Copilot | Daily autocomplete | ❌ | Unpredictable pricing, no cost visibility |
| Cursor 3.0 (default) | Agent-mode refactors | ❌ | Auto-applies migrations, deletes files unprompted |
| Cursor (auto-apply OFF) | Controlled agent assistance | ✅ | Review every diff, approve migrations manually |
| Cline (BYOK) | High-stakes multi-file work | ✅ | Explicit approval per step, model choice per task |
| Claude Code CLI | Terminal-native workflows | ⚠️ | Powerful but simulator debugging breaks IDE flow |
The Pivot Point
New hire spun up Cursor, accepted “helpful” suggestion to “fix the schema.” Cursor ran prisma migrate dev against local DB — destructive, no confirmation. Lost 45 minutes rebuilding seed data. Realized Cursor’s “agentic” default is a liability for any team touching data layers. Disabled auto-apply globally: cursor.chat.agent.autoApply: false, cursor.editor.autoApplyEdits: never.
What We Use Now
Cursor (configured defensively) — auto-apply OFF, require approval for all edits, terminal commands, and migrations. Daily driver for autocomplete, inline edits, test generation. Cline (BYOK via OpenRouter) — for any task touching DB schema, auth, payments, or >5 files. Explicit per-step approval, model routing (Sonnet 3.5 for architecture, DeepSeek for bulk). Claude Code — only for greenfield scaffolding or CI/CD scripts where sandbox is disposable.
When You’d Choose Differently
- Solo greenfield projects: Cursor default autonomy speeds up scaffolding
- Teams with strong CI gates: Auto-apply risk mitigated by PR reviews
- Non-data workloads: Frontend-only, no migrations = lower autonomy risk
