4. Team Use: Consider Cursor's collaboration features

AI coding assistants are powerful tools for improving development efficiency. Choose based on your work habits and needs.

Selection Decision Matrix

Use-case comparison across the four tools:

Scenario	Aider	Continue	Cursor	Claude Code
Heavy CLI users	✅ first choice	❌	❌	✅ alt
Don't want to switch IDE	⚠️ need terminal	✅ first choice	❌	⚠️ need terminal
Complex refactoring	⚠️ medium	⚠️ basic	✅ first choice	✅ strong
Large monorepo	⚠️ medium	⚠️ medium	✅ first choice	⚠️ depends on config
Team collaboration	⚠️ config Git	❌	✅ strong	⚠️ workflow-dependent
Local / privacy model	⚠️ supported	✅ first choice	❌	❌
Multi-model switching	✅ strong	✅ strong	⚠️ Claude/GPT only	⚠️ mainly Anthropic
Cost	free (API)	free (API)	$20/month	API cost

True Cost Structure for Team Rollout

Most people only count "tool subscription", but real costs are far higher:

• Aider: $0 subscription, but each developer needs API key; with many users, token cost scales linearly
• Continue: $0 subscription, same as above; if using local models, hardware cost rises
• Cursor: $20/month per user, 10-person team $2400/year; looks expensive but time saved often exceeds the subscription
• Claude Code: API-billed (per token), large projects can run $50-200/month per user

Rule of thumb:

• Under 5 people: Cursor has best price-performance
• 5-20 people: Aider/Continue with a centralized API account
• 20+ people: evaluate unified subscription vs BYO model

Workflow Integration with IDEs

Integration depth directly affects daily use:

• Aider: detached from IDE; developer writes code in IDE + runs AI commands in terminal. High context-switching cost
• Continue: as VS Code / JetBrains plugin, best integration; no need to leave the editor
• Cursor: replaces IDE, completely new workflow; highest learning cost but deepest integration
• Claude Code: terminal-first, fits CLI-comfortable developers; can plug into VS Code extension

"Controllability" of Code Generation

Four tools differ in control granularity over generated code:

• Aider: every generation auto-commits to Git, easy to roll back one by one; best for "trial-and-error" development
• Continue: supports inline edit and panel mode, but auto-commit requires manual action
• Cursor: Composer mode generates large blocks at once; undo requires Ctrl+Z
• Claude Code: finer-grained auto-commit, suits scenarios needing frequent save points

Selection Decision Table

Your situation	Recommended tool
CLI + Git flow native	Aider
Don't want to leave VS Code	Continue
Team refactors large projects	Cursor
Primarily Anthropic models	Claude Code
Privacy sensitive / must local	Continue + local model
$0 budget	Aider or Continue

Common Misconceptions

• "Cursor is always best" — it's friendly to VS Code users, but Vim / JetBrains users may not adapt
• "Aider is outdated" — in Git-centric workflows it's still the most stable
• "Continue only installs in VS Code" — JetBrains series all have plugins
• "Claude Code is only for Anthropic models" — can plug into other models via config

Mixed Usage in Real Workflows

Many teams ultimately don't pick one but combine:

• Aider for large refactors (Git-diff friendly)
• Continue for daily inline completion (stay in IDE)
• Cursor for monorepo exploration (Composer is strong)
• Claude Code for cross-file understanding (long context)

This "tool combination" is most common in 5-20 person teams. The prerequisite is that team members are willing to configure different accounts and workflows for different tools.
