Google Antigravity 2.0 shipped with the loudest pitch of the agentic-IDE wave: drop a goal, the agent plans, edits across files, runs commands in a sandboxed terminal, opens a browser to verify, and reports back with screenshots. The first time it works on a non-trivial feature it is genuinely impressive. The XDA review captured the catch most working developers have run into: it works beautifully on the demo path and falls over the moment you point it at a real codebase with conventions it does not share. People who paid for the Pro tier started asking the obvious question on r/programming and Hacker News: what else is out there?
We tested seven Antigravity alternatives across Windows, macOS, and Linux. The list spans full editor replacements, agents that live inside VS Code, and CLI tools that drop into any workflow. Each pick is judged on plan quality, edit reliability, and how well it cooperates with the rest of a working developer’s stack.
Quick comparison

Why people leave Antigravity
The complaints clustered in three buckets across the first weeks of 2.0.
The pricing model is opaque. Antigravity sells a tier with “agentic credits” that get consumed at unpredictable rates depending on which Gemini model the agent decides to call. Users on r/Antigravity report bills that varied by an order of magnitude on weeks with comparable work.
Plan quality drifts on long-running tasks. The agent’s planner is strong out of the gate, but multi-hour sessions accumulate context that derails the next plan. Resetting context loses progress; carrying it forward makes the agent slower and less accurate.
The browser-verification flow is sandboxed in a way that misses most real apps. Authenticated SaaS, anything behind a corporate VPN, and most internal tools are invisible to Antigravity’s verifier. The screenshots are pretty when the demo works, and useless when it does not.
Conventions get ignored. Antigravity tends to write code in Google’s idiomatic style regardless of what your repo’s .editorconfig, ruff config, ESLint setup, or prevailing patterns suggest. Repos with strong house style produce review comments shaped like “good edit, wrong style” on every PR.
The 7 best Antigravity alternatives
Cursor — best full editor replacement with a mature agent
Cursor is the fork of VS Code that put agentic coding in front of mainstream developers first, and it still has the most polished take. The Composer agent plans multi-file changes, shows a unified diff before applying, runs your test command, and reports back. The keymap, extensions, settings.json, and most muscle memory move over from VS Code on day one. Anthropic’s Claude models are the default driver, with model switching available per request.
Where it falls short: The tier with full agent access is one of the more expensive in the category. The fork lags VS Code releases by a few weeks. Very large monorepos still have indexing rough edges.
Pricing:
- Free: Limited usage tier with reduced model access
- Pro: Around $20/mo for the full agent flow
- vs Antigravity: Comparable price, more predictable billing, less ambitious “verify in a browser” loop
Switching from Antigravity: Cursor’s Composer fills the same role as Antigravity’s planner. The mental model carries over; the difference is that Cursor leans on the developer to verify changes rather than promising a browser-based check.
Download: Cursor for Windows / macOS / Linux
Bottom line: Pick Cursor when you want one tool that does most of the agentic work, with billing you can model in advance.
Claude Code — best terminal-native agent across any editor
Claude Code is the agent that does not care which editor you use. It runs in a terminal, reads and edits files in the current directory, runs commands, and reports back. Pair it with VS Code, JetBrains, Neovim, or no editor at all — the working contract is the same. The agent is unusually disciplined about asking before destructive operations and reading enough context to make non-trivial changes correctly the first time.
The XDA piece that wrote off Antigravity ended on Claude Code for exactly this reason: the agent is doing what the agent should do, and your editor is doing what the editor should do, and the two stop fighting each other.
Where it falls short: No in-editor diff UI by default — you read the changes after the fact in your editor’s git view. API token cost adds up on large refactors and is not capped by a flat subscription on the API plan.
Pricing:
- Free: Trial included with Claude.ai accounts
- Claude Pro / Max plans: Flat monthly fee bundles Claude Code usage
- Pay-as-you-go: API tokens at standard Anthropic pricing
- vs Antigravity: More predictable on the flat-fee plans, more honest about what it cannot do
Switching from Antigravity: Install Claude Code, run it in the repo root, the agent picks up the context. Antigravity’s planner UI has no exact equivalent — Claude Code shows its plan as text in the terminal and asks before each major step.
Download: Claude Code install guide
Bottom line: Pick Claude Code when you already have an editor you love and you want the agent to live alongside it, not replace it.
Windsurf — best VS Code fork with Cascade flow
Windsurf (from Codeium, now part of OpenAI) is the other major VS Code fork with agents at the centre. The Cascade feature plans, edits, and verifies in a single flow, and the model-routing behind the scenes picks faster models for quick edits and stronger ones for planning. The free tier is more generous than Cursor’s, and the upgrade path is cheaper.
For Antigravity refugees who liked the planner-first feel but wanted predictable billing, Windsurf is the cleanest swap.
Where it falls short: The fork has churned through pricing models several times in the past year. Some power features remain better in Cursor.
Pricing:
- Free: Useful free tier with monthly credits
- Pro: Around $15/mo
- vs Antigravity: Cheaper, simpler billing, less ambitious browser verification
Switching from Antigravity: Windsurf imports VS Code settings on first launch. The Cascade flow is the closest mental analogue to Antigravity’s planner.
Download: Windsurf for Windows / macOS / Linux
Bottom line: Pick Windsurf when you want a Cursor-class flow on a smaller budget.
Cline — best open-source agent inside VS Code
Cline is the open-source VS Code extension that gives the rest of the ecosystem a credible agent without leaving the editor. Bring your own API key — Claude, OpenAI, OpenRouter, or any OpenAI-compatible local endpoint like Ollama — and Cline takes over the agentic workflow inside VS Code. The MCP server support lets it pull in browsers, databases, and ticket systems as tools.
Where it falls short: Performance depends entirely on the underlying model and your API budget. The UX has improved through 2025 but still feels like an extension panel rather than a first-class editor flow.
Pricing:
- Free: Apache 2.0 extension; you pay only for API tokens
- vs Antigravity: Free at the tool layer, fully transparent token billing
Switching from Antigravity: Install Cline in VS Code, point it at your preferred API. The agent’s pattern (plan, edit, ask) is similar; the main difference is the UI lives in a VS Code side panel rather than a separate Antigravity window.
Download: Cline on the VS Code marketplace
Bottom line: Pick Cline when you want an agent inside the original VS Code without committing to a closed-source product.
Aider — best CLI agent with git integration
Aider is the CLI agent built around git. Every edit becomes a git commit with an attributed message, which makes the agent’s work reviewable through normal git log and git diff. The pair-programming flow — describe the change, see the diff, accept or revise — is the cleanest of the CLI tools.
Where it falls short: No interactive editor. The workflow assumes you have your code in an editor and switch to Aider in a terminal to make changes. Large repositories need configuration to avoid context bloat.
Pricing:
- Free: Apache 2.0; you pay only for API tokens
- vs Antigravity: Free at the tool layer, more disciplined audit trail per change
Switching from Antigravity: Aider has no in-editor UI. The audit trail is the upside — every change is a commit, code review tools like GitHub PRs handle the diff.
Download: Aider installation
Bottom line: Pick Aider when you want every agent edit to land as a reviewable git commit by default.
Zed — best native editor with built-in agents
Zed is the rare modern editor that is not a VS Code fork. The Rust-based core is fast, the collaborative editing actually works, and the agent panel ships in the editor itself. Through 2025 it added the planning and multi-file editing patterns that Cursor and Windsurf made standard. Bring your own API key or use Zed’s hosted tier.
Where it falls short: The extension ecosystem is younger than VS Code’s. Language servers and debug adapters cover the major languages but not every niche. Coming from a heavily customised VS Code setup means rebuilding configuration.
Pricing:
- Free: Open-source editor; agent panel has a generous free tier
- Zed Pro: Around $20/mo for hosted models
- vs Antigravity: Comparable price, dramatically faster editor performance
Switching from Antigravity: Plan an editor migration first — Zed is its own editor, not a VS Code fork. Bring your API key for Claude or OpenAI and the agent panel is configured.
Download: Zed for macOS / Linux / Windows
Bottom line: Pick Zed when editor performance matters and you accept rebuilding your editor configuration from scratch.
GitHub Copilot — best agent integrated with pull requests
GitHub Copilot has caught up with the agentic-IDE wave. Copilot Workspace handles plan-edit-verify inside a draft pull request, Copilot Chat lives in VS Code and JetBrains, and the Copilot Coding Agent can take an issue and turn it into a PR autonomously. For teams whose code review already centres on GitHub PRs, the integration is the closest the ecosystem has to a default.
Where it falls short: Tied to GitHub. No GitLab or Bitbucket version. Outside the PR flow the editor experience is the older Copilot autocomplete, not a Cursor-class agent.
Pricing:
- Free: Limited tier with monthly chat and completion caps
- Pro: Around $10/mo
- Business / Enterprise: Per-seat with policy controls
- vs Antigravity: Cheaper, tighter integration with code review
Switching from Antigravity: Enable Copilot in VS Code or the JetBrains IDE. For agent-style work, use Copilot Workspace from a GitHub issue rather than from the editor.
Download: Copilot signup
Bottom line: Pick Copilot when your team’s workflow already centres on GitHub PRs and you want the agent to live where the review happens.
How to pick the right one
If you want one tool that replaces Antigravity end-to-end with predictable billing, install Cursor. If you already have an editor you love, install Claude Code in a terminal and keep your editor.
If “open-source inside VS Code” is the constraint, install Cline and bring your own API key. If every edit needs to land as a git commit, use Aider. If you want the Cursor flow on a smaller budget, install Windsurf.
If editor performance matters more than extension catalogue, try Zed. If your team already lives in GitHub PRs, Copilot is the easiest add-on with the deepest review integration.
Stay on Antigravity when the browser verification flow happens to fit your stack (mostly internal apps with no auth wall) and the credit-based billing is acceptable. That is a narrow band.
FAQ
What is the best free Antigravity alternative?
Cline plus your own API key is the freest credible agent inside the original VS Code. Aider is the freest CLI agent. Windsurf’s free tier is the most generous “real editor” option.
Is Claude Code better than Antigravity?
For developers who already have an editor they like, yes — Claude Code stays out of the editor’s way and is unusually disciplined about asking before destructive operations. For developers who want one tool that does everything in one window, Cursor or Windsurf is a closer swap.
Can I run Antigravity-style agents on a local LLM?
Cline and Aider both support OpenAI-compatible local endpoints, which means Ollama, LM Studio, or vLLM can drive the agent. Quality drops with smaller models. A 70B-class model running locally is the practical floor for non-trivial multi-file edits.
Does Cursor still use Claude or did the model situation change?
Cursor defaults to Claude for the Composer agent and lets you switch models per request. Anthropic, OpenAI, and Google models are all available depending on the plan tier.
What is the cheapest Antigravity alternative for a small team?
GitHub Copilot Business is the lowest per-seat cost for a small team that already uses GitHub. Windsurf Pro and Cursor Pro Teams come in next. Bring-your-own-key tools (Cline, Aider, Continue) cost only the API tokens, which can be cheaper still depending on usage.
