Short answer: Claude Code is a terminal-first CLI agent, while Cursor and Antigravity are agents embedded inside an IDE; as of August 2026, Claude Opus 5 leads code-repair benchmarking (SWE-bench Verified) by a clear margin, GPT-5.6 Sol leads terminal-task benchmarking (Terminal-Bench 2.1), and Antigravity is still in free public preview. Which one fits depends on whether you spend more time in a codebase or in a terminal.
All three get called "AI coding agents," but they answer a different question: Claude Code answers "do this task and report back," while Cursor and Antigravity answer "stay beside me while I edit."
What Category Does Each Agent Fall Into?
The three agents fall into three different categories: Claude Code is a terminal-first CLI tool, Cursor is a VS Code fork, and Antigravity is Google's agent-first development platform, shipped as its own separate desktop app. OpenAI's Codex is a fourth player in this same category, but this piece focuses on the three leading contenders.
That category difference plays out concretely: you can leave Claude Code running in a terminal tab, tell it "make these tests pass, then summarize," and switch to something else; with Cursor and Antigravity, you generally stay in the IDE window and approve suggestions line by line. Antigravity 2.0 shipped as a standalone desktop app on May 19, 2026, and its model picker offers Gemini 3 Pro/Flash, Claude Sonnet/Opus, and the open-weight GPT-OSS-120B side by side.
How Should You Read Benchmark Leadership?
The rule for reading benchmark leadership: check which task the number actually measures, not the "best model" label attached to it. On SWE-bench Verified as of August 27, 2026, Claude Opus 5 leads at 96% — a score that measures solving real GitHub issues against a human-verified subset. Terminal-Bench 2.1 tells a different story: GPT-5.6 Sol leads at 89.5%, with Claude Opus 5 — Claude Code's default model since July 24, 2026 — trailing by less than half a point at 89.1%.
One caution when comparing these numbers: different versions of Terminal-Bench (2.0, 2.1, 3.0) aren't directly comparable, because each new version is harder than the last. Checking which version a claim like "model X leads Terminal-Bench" actually refers to makes a real difference.
Category | Claude Code | Cursor | Antigravity |
|---|---|---|---|
Interface | Terminal / CLI | VS Code-based IDE | Standalone desktop app |
Default model | Claude Opus 5 | Variable (model picker) | Model picker (Gemini, Claude, GPT-OSS) |
SWE-bench Verified leader? | Yes (96%, Opus 5) | No, depends on model picked | No, depends on model picked |
Terminal-Bench 2.1 | 89.1% (Opus 5, second) | Not directly measured | Not directly measured |
Entry pricing | ~$17/mo (annual Pro) | $20/mo (Pro) | Free during preview |
Top-tier pricing | $200/mo (Max 20x) | $200/mo (Ultra) | Not announced post-preview |
How Do Parallel Sub-Agents and Overnight Runs Differ?
Parallel sub-agent support and background execution is where the three tools diverge the most. Claude Code natively supports subagent and background-agent workflows — a main session can fan work out to multiple sub-tasks in parallel, and background agents show status only by default, not every tool call. Cursor and Antigravity both have background/agent modes too, but their core design still orbits the IDE window — leaving a task entirely in the terminal and walking away isn't as native as it is in Claude Code.
That gap shows up most clearly on long, overnight runs: wiring a task into a CI pipeline or a scheduled job integrates with less friction when the tool was built terminal-first.
How Do the Pricing Tiers Compare?
Comparing pricing tiers, entry-level pricing sits close together: Claude Code Pro starts around $17/month on an annual plan, while Cursor Pro runs $20/month (up from a previous $15 price point). At the top end, both hit $200/month — Claude Code Max 20x and Cursor Ultra. Antigravity remains in free public preview with what Google calls "generous" Gemini usage limits; pricing after the preview ends hasn't been announced.
Anthropic prices Claude Code not as a standalone product but as part of whichever Claude subscription you already pay for — so the real comparison isn't Claude Code's own price, it's which Claude plan you actually need. Cursor's Team plan also moved from $30 to $40 per seat, which tracks a broader 2026 trend of IDE agents raising prices.
Which Workflow Calls for Which Tool?
If you want to hand off a task entirely and read the report later, Claude Code wins; if you want to see every suggested change line by line while staying inside your IDE, Cursor or Antigravity wins. A common combination has emerged: a CLI agent (Claude Code) for large, multi-file tasks, an IDE agent (Cursor or Antigravity) for fast edits, and a PR-review bot running on the same "trust, but verify" principle as a final check.
My honest take: treating these three as rivals is the wrong frame — the real question is which one stays open by default. I keep Claude Code running in a terminal tab for large refactors and reach for the IDE only for small, visually-tracked changes. Hosting Claude Code's skills on GitHub is also part of making that terminal-first workflow repeatable across a team, rather than something one developer does alone.
Frequently Asked Questions
Does Claude Code or Cursor write better code?
Both can run on the same underlying models, so the real difference is interface philosophy, not code quality: Claude Code defaults to Claude Opus 5 and inherits that model's 96% lead on SWE-bench Verified, while Cursor offers a model picker, so performance depends on which model you select. There's no single answer to "better code" — it depends on which model you're actually running.
Will Antigravity stay free?
As of August 2026, Antigravity is still in free public preview with what Google describes as generous Gemini usage limits, but no permanent pricing has been announced for after the preview ends — so there's no guarantee it stays free.
Can I compare a Terminal-Bench 2.1 score directly to a Terminal-Bench 2.0 score?
No. Difficulty changes between Terminal-Bench versions — 2.1 is harder than 2.0 — so comparing one model's 2.0 score directly against another model's 2.1 score is misleading. Always check that you're comparing scores from the same version number.
Is it common to use all three tools together?
Yes — the combination that's emerged pairs a CLI agent (Claude Code) for large, multi-file tasks with an IDE agent (Cursor or Antigravity) for fast edits, plus a separate PR-review bot as a final check. They don't do the same job, so they don't compete for the same slot in your workflow.
