If you write code in 2026 and you've used GitHub Copilot for the last three years, you've probably already realized it's not enough. The interesting work has moved into the IDE — agents that read your repo, write across files, and run tests on their own. Three editors are fighting for that crown right now: Cursor, Zed, and Antigravity.
We've used all three daily for a month each. Here's the verdict.
The short version
Cursor wins as the daily driver for most developers. Zed wins on speed and is the right pick if your editor lag actively annoys you. Antigravity is the best free option and the most ambitious agent of the three — but you're betting on a Google preview.
If you live in the terminal, the answer is none of these. Claude Code or Codex CLI bundled with your existing AI subscription will eat your IDE budget alive.
Pricing snapshot (2026)
Approximate, in USD, before taxes. Pricing changes — these are accurate as of mid-2026.
- Cursor Pro — $20/mo. Includes AI requests across Claude, GPT, and Gemini.
- Cursor Business — $40/mo per seat. Adds team admin and SSO.
- Zed — Free with bring-your-own model API key. Zed Pro at ~$20/mo bundles Zed AI requests so you don't need a separate API key.
- Antigravity — Free during the public preview. Tied to Gemini.
Cursor — The mature default
Cursor is a fork of VS Code with AI fused into every interaction. Tab autocomplete that understands the rest of your file, an agent mode that can edit across multiple files, native Model Context Protocol (MCP) support, and the ability to route a single chat between Claude, GPT-5.4, and Gemini 3 depending on what you need.
The strengths are obvious: it's the most polished, has the deepest plugin and MCP ecosystem, and "just works" for almost any language. If you've used VS Code, you're at home in five minutes.
The weaknesses show up after a month. Memory usage climbs aggressively if you keep dozens of tabs open — Electron is doing what Electron does. Agent runs occasionally hit limits that feel undocumented, especially on Pro. And the $20/month is a real cost on top of whatever you're already paying for Claude or ChatGPT.
Zed — The speed pick
Zed is written in Rust, uses GPU-accelerated rendering, and feels like a native macOS app because it is one. It opens 10,000-line files instantly. Cmd+P fuzzy search across a large repo doesn't have the half-second pause Cursor sometimes gives you. You'll notice the difference within the first hour.
Zed AI is decent — chat in a side panel, an agentic edit mode that's improving fast, and the ability to bring your own API key for Claude, GPT, or any major model. The free tier with BYO key is the actual selling point: you can pay for one AI subscription instead of two.
The weaknesses are coverage and maturity. The plugin ecosystem is smaller than VS Code's; if your daily workflow depends on a specific extension that doesn't have a Zed equivalent yet, you'll feel it. Agent mode is genuinely getting better month over month, but Cursor is still ahead on multi-file edits and MCP integration depth.
Antigravity — The free wildcard
Antigravity is Google's agentic IDE built around Gemini. Launched late 2025, free during the public preview as of this writing. It's the youngest of the three and the most explicitly bet-the-farm on agents — the entire UI is designed around "give the agent a task and walk away" rather than the inline-pair-programming model Cursor uses.
For agentic tasks, it's surprisingly good. Hand it a multi-file refactor and the long-context Gemini 3 Pro model will plow through more aggressively than Cursor's agent will. The feedback loop — agent attempts, tests run, agent self-corrects — is tighter than what Cursor ships by default. And it's free.
The downsides: Gemini-only (no Claude, no GPT), the editor itself is less mature than Zed's, and "free during preview" is a clock counting down. Google could keep it free forever or pivot it to a $30/month tier next quarter. You're betting on a preview.
What about Claude Code?
Worth naming the elephant in the room. Claude Code is Anthropic's terminal-based coding agent, bundled with Claude Pro at no extra cost. Codex CLI does roughly the same thing for ChatGPT subscribers. Neither is an IDE — they're CLI agents you point at a directory.
If you're already paying $20 for Claude or ChatGPT and you're comfortable in a terminal, those tools are the highest-leverage AI coding subscription on the market. They eliminate the need for a separate IDE AI bill entirely. The tradeoff is the IDE-style "tab to accept" workflow Cursor and Zed offer — Claude Code doesn't have that. It's a different mental model.
If you mostly want an editor with AI in it, this article. If you mostly want an agent that does work for you, Claude Code or Codex.
The verdict
Pick Cursor if you want one tool to handle everything and don't want to think about it. It's the most mature, has the broadest ecosystem, and routes between AI models so you're never stuck on the wrong one for a task. $20/month, worth it if you're paid to write code.
Pick Zed if your editor speed actively annoys you, you live on macOS, and you're already paying for Claude or ChatGPT (so BYO key works). Free with your existing AI subscription, $20/month for Zed AI if you don't want to manage keys. Zed's the underdog pick that gets stronger every month.
Pick Antigravity if you want to play with the most aggressive agentic workflow on the market and you're fine with Gemini-only. It's free, it's good, and the worst case is you go back to Cursor in three months — at which point you'll have learned what agentic coding actually feels like.
FAQ
Which AI IDE is best in 2026?
Cursor is the best daily-driver AI IDE for most developers in 2026 because of its multi-model support, mature MCP ecosystem, and polished agent mode. Zed wins on speed and Mac-native feel. Antigravity is the best free option and excels at long-running agentic tasks. If you live in the terminal, Claude Code or Codex CLI may eliminate the need for any of these entirely.
Is Cursor worth $20/month if I already pay for Claude or ChatGPT?
It depends on whether you want a polished IDE shell or a CLI agent. Cursor Pro at $20/month bundles AI requests into the editor. If you already have Claude Pro or ChatGPT Plus, Claude Code and Codex CLI come included and run in the terminal — no extra subscription. Cursor is worth it if you specifically want the VS Code-style IDE experience with multi-model routing.
Is Antigravity actually free?
Yes — during the public preview. Google launched Antigravity in late 2025 as a free agentic IDE built around Gemini. Expect a paid tier when it leaves preview, similar to how Cursor and Zed Pro are priced today. Use the free window while it lasts.
Why is Zed faster than Cursor?
Zed is written in Rust and uses GPU-accelerated rendering. Cursor is a fork of VS Code, which is built on Electron — a Chromium browser running JavaScript. The difference is most noticeable on file open, large project search, and scrolling long files. On a fresh M-series Mac you'll feel the gap; on a fast desktop CPU it's less obvious.
Can I use Claude or GPT in Zed and Antigravity?
Zed yes, Antigravity no. Zed lets you bring your own API key for Claude, GPT, or other models. Antigravity is built around Gemini and does not currently support other models. Cursor is the most flexible — it routes between Claude, GPT, and Gemini natively and lets you pick per-request.
