Type	Terminal-based agent (CLI)	Full IDE (VS Code fork)	Editor plugin (VS Code, JetBrains & more)	Full IDE (VS Code fork)
Autonomy level	High — plans, edits multi-file changes, runs commands, coordinates multi-agent teams	Ranges from Tab autocomplete up to full multi-file Agent mode	Started as autocomplete; now has an Agent mode for multi-file edits and PR review	High — its Cascade agent plans and executes multi-file changes
Free tier	No standalone free tier — bundled into Claude's own plans	Yes — Hobby tier	Yes — 2,000 completions + 50 chat requests/month	Yes — unlimited Tab autocomplete plus a light agent quota
Entry paid price	From $20/mo (Claude Pro includes Claude Code access)	$20/mo (Pro) — higher tiers exist, worth checking current pricing	$10/mo (Pro) — cheapest entry point of the four	$20/mo (Pro)
Underlying models	Anthropic only — Sonnet 5, Opus 5, Haiku 4.5, Fable 5	Multi-model — Claude, GPT, Gemini, Grok, plus its own Composer model	Multi-model via a shared credit pool — GPT, Claude, and Gemini variants	Primarily its own SWE-1.5 model, with some third-party model access
Standout feature	Deepest whole-codebase agentic reasoning, terminal-native workflow	Best model flexibility inside a single IDE	Tightest GitHub/PR/Actions integration, cheapest entry price	Fast in-house model (SWE-1.5) with simple, predictable pricing
Best for	Developers wanting maximum autonomy on complex, multi-file work	Developers who want to pick the best model per task without switching tools	Teams already living in GitHub/VS Code; a low-cost on-ramp for beginners	Solo developers or freelancers wanting a fast, affordably-priced full IDE

A Quick Note on Windsurf

Windsurf was acquired and rebranded under Cognition's Devin AI name in mid-2026 — if you're researching it, you may see it referred to under either name depending on how recently a source was written. The product itself (the Cascade-powered IDE) is the same; only the branding has shifted.

The Short Version

These four solve overlapping but distinct problems. Claude Code is the most "agentic" — it's built to be handed a real task and left to work through it across many files and terminal commands. Cursor and Windsurf are both full IDEs with strong built-in agents, differing mainly in model choice (Cursor lets you pick from several providers; Windsurf leans on its own fast in-house model). GitHub Copilot is the odd one out structurally — a plugin that lives inside your existing editor rather than replacing it, which makes it the easiest to adopt without changing your workflow.

Best for Solo Developers & Freelancers

If cost and simplicity matter most, GitHub Copilot's $10/month entry tier is hard to beat, especially if you're already using VS Code or JetBrains. If you want a more autonomous agent without leaving a familiar-feeling IDE, Windsurf's fast in-house model and straightforward pricing make it a strong pick for freelancers who bill by the project rather than the hour.

Best for Teams & Complex Codebases

Claude Code's ability to coordinate multiple agents and work autonomously across an entire codebase makes it the strongest choice once a task genuinely spans many files and steps — refactors, migrations, or building a feature end-to-end. Cursor is a strong team choice too, particularly if different engineers prefer different underlying models for different kinds of work.

Pricing at a Glance

GitHub Copilot has the lowest entry price at $10/month. Claude Code, Cursor, and Windsurf all cluster around $20/month for their standard paid tier, with higher usage tiers above that (Cursor and Windsurf both offer higher tiers reported in the $100–200/month range for heavy use — pricing structures for these two shift fairly often, so check their current pricing pages directly before committing).

Our Verdict

There isn't a single winner — it genuinely depends on how autonomous you want the tool to be and how much you value model choice versus simplicity. For serious, multi-file agentic work: Claude Code. For flexibility across models inside one IDE: Cursor. For the cheapest, lowest-friction entry point inside an editor you already use: GitHub Copilot. For a fast, simply-priced full IDE: Windsurf.
