Detailed Breakdown

1. Claude Code (Recommended)

Free tier · claude.ai/code · Terminal-based

Largest context window of any tool (200K tokens — 500 pages of code at once)
Works in your existing terminal — no new IDE to learn
Best code quality for complex, multi-file refactors
Connects to Git, can run tests, execute commands
Free tier is genuinely useful (not a crippled trial)
No vendor lock-in — if Claude shuts down, you keep your workflow

Requires API key setup (minor friction vs. native IDE integration)
No native GUI — purely terminal
Cannot see your screen visually (unlike Cursor's Composer)

Verdict: Best overall. Free tier covers 80% of use cases. If you live in a terminal, this is the tool.

2. Cursor

$20/month · cursor.com · Built on VS Code

Best UX for developers switching from VS Code — zero learning curve
500K token context in Pro plan (largest of any IDE-based tool)
Composer feature for multi-file visual editing
Tab autocomplete is excellent for boilerplate
Good for beginners who find terminal intimidating

Only works inside Cursor IDE — lock-in to their fork of VS Code
$20/mo for features available elsewhere for less or free
Bug fixes and features lag behind VS Code base
Less powerful for CLI-focused workflows

Verdict: Good if you're new to coding or refuse to use the terminal. But you pay $20/mo for convenience and lock yourself into their IDE.

3. Windsurf

Free tier · codeium.com/windsurf · Codeium IDE

Actually free for individual use (not a trial)
Cascade AI agent built-in — good for autonomous file editing
Lightweight compared to Cursor
Fast, less resource-intensive than Cursor

Windsurf-only IDE — same lock-in problem as Cursor
Code quality is noticeably below Claude and Copilot for complex tasks
Still maturing — bugs and edge cases
Context window smaller than competitors (128K)

Verdict: Best free option if you refuse to pay and don't want the terminal. But Claude Code free is better.

4. GitHub Copilot

$10/month · github.com/features/copilot · All major IDEs

Works in VS Code, Neovim, JetBrains — no new IDE needed
Tightest IDE integration of any option
Fast autocomplete for simple completions
Trusted by enterprises — good for showing clients
Cheapest paid option at $10/mo

Small context window (18K tokens) — struggles with large files
Code quality for complex tasks is below Claude
Autocomplete-first, not agent-first — you have to drive it
Less capable for full refactors or large changes

Verdict: Fine for simple autocomplete. But at $10/mo vs Claude free, the value proposition is weak unless you need enterprise compliance features.

5. Aider

Free / $12/mo · aider.chat · Terminal-based

True offline mode — your code never leaves your machine
Works with any editor — you're not locked into an IDE
200K token context window
Git-aware — can commit, diff, and reason about changes
Best privacy option — critical for proprietary client work
Open source — transparency and community-driven

Steeper learning curve — terminal-only, no GUI
Requires API key setup (like Claude Code but more manual)
Less polished than Claude Code for large refactors
Smaller community, fewer tutorials

Verdict: Best for privacy-conscious developers or those who need offline capability. Otherwise Claude Code's superior quality wins.
