Google Antigravity emphasizes experimentation and autonomous task completion more. Its multi-agent control via the Manager view, agent-driven browser recording, and collaborative multi-file editing allow agents to execute tasks with minimal human intervention.
Technical foundations and code understanding
To evaluate an AI coding assistant, it’s crucial to see how it handles code and context. For instance, Cursor takes a refined and developer-friendly approach. Using proprietary composer models and smart indexing, it pulls only the most relevant files into content. This means that it maintains a strong understanding of code, dependencies, and intent. It excels at predictable edits, debugging, and refactoring, so you can use it for large projects where control and stability matter.
In comparison, Google Antigravity focuses on scale and flexibility. Built on Google’s Gemini models, it uses a massive context window to handle large parts of a codebase at once. This helps it understand complex architectures and cross-file dependencies, and its agent-driven workflow can make broad changes automatically. This makes it especially well suited for high-level reasoning and large, interconnected codebases.
Agent architecture and workflow automation
Looking at agent architecture and workflow, these tools take different approaches. Cursor is less independent and sticks to a guided, developer-in-the-loop model. Its AI acts as an assistant that suggests edits, completes code, and provides inline help, but you stay in full control – accepting, adjusting, or rejecting suggestions. This approach feels predictable and keeps you involved in every step, which many developers find comforting and reliable for real work. On the downside, it takes more of your time.
In contrast, Google Antigravity’s autonomous agents can plan, execute, and validate tasks across the editor, terminal, and browser without your constant input. These agents can run multi‑step workflows like feature generation, testing, or environment setup with minimal direction, potentially saving time and mental overhead on routine tasks.
Agent autonomy is most effective when you require quick prototyping or unattended task execution, particularly for repetitive or multi-stage work. However, that same autonomy introduces risks: unexpected actions, unpredictable edits, and challenges understanding why an agent made a given change. In environments where safety, auditability, and code correctness matter, this can be problematic.
Performance, speed, and large codebase handling
To evaluate Cursor vs Google AntiGravity performance, I collaborated with our in-house research team. Together, we discovered that both AI coding IDEs are fast and capable in day-to-day use, but they optimize for different things.
Cursor is built around a developer-centric workflow, prioritizing low latency, fast inline suggestions, and tight human oversight. In practice, this results in a responsive IDE that supports continuous coding, incremental edits, and long sessions without major slowdowns. Resource usage is predictable, and even during multi-file refactors, Cursor remains stable and easy to audit.
Google Antigravity takes a more ambitious approach. Its agent-first architecture assigns autonomous agents to handle larger tasks like multi-file refactoring, testing, or documentation generation. This enables parallel and asynchronous work, which pays off when dealing with large codebases or complex changes spanning many files. While individual interactions may feel slightly less immediate, Google Antigravity compensates by handling broader workloads at once and reducing manual effort.
From a usability standpoint, especially as a non-professional developer, the difference can feel subtle – both IDEs get the job done, and much depends on the underlying model and UI preference. However, architecturally, the key distinction is context ownership: Cursor tightly controls context for safety and determinism, while Google Antigravity allows the model more freedom, enabling deeper reasoning at scale.
Safety, privacy, and data security
Safety and data security are top priorities for developers, especially when an AI tool can touch your terminals, files, and source code. With Cursor, the AI acts as an assistant within the editor rather than a fully autonomous agent, meaning you can stay in control of every change. What’s more, the tool’s permission model and guardrails require explicit confirmation before making actions, limiting unintended edits or risk terminal commands. So, for teams and enterprises with strict audit and compliance requirements, Cursor is a safe choice.
On the security front, Google Antigravity isn’t so thorough. Its autonomous agents can execute tasks across terminals and files with minimal input, which speeds up workflows but can also mean missteps. While Antigravity includes permission prompts and user confirmations for more impactful actions, its looser guardrails increase the risk of accidental command execution or unintended changes, especially if an agent misinterprets a goal.
Overall, data handling and telemetry practices are similar between the tools. However, if you own an enterprise, you might want to lean toward predictability over fluid automation when safeguarding sensitive data.
Price and overall value
At the time I'm writing this review, Google Antigravity is on public preview. This means that the tool is free of charge, making it an obvious choice for anyone looking for an AI coding assistant. However, I'll still go through Cursor vs Google Antigravity plans and what they offer.
Cursor offers a variety of plans for both individual and business users, along with some add-ons. There's also a free plan, which allows you to test the Pro plan for one week, but with limited Agent requests and Tab completions. Paid plans start from $20.00/month, giving you extended limits on Agent requests, unlimited Tab completions, background Agents, and maximum context windows. With higher tiers, you can also get more usage on all OpenAI, Claude, and Gemini models.
Google Antigravity also has plans for both individuals and businesses. However, not all of them are available yet. For now, you can use it for free, with access to Gemini 3 Pro and Flash, Claude Sonnet and Opus 4.5, gpt-oss-120b, unlimited Tab completions and Command requests, and generous weekly rate limits. Just keep in mind that there's likely a zero chance that it will stay free forever, and nobody knows what the pricing might be.
Real-world usage scenarios
In real-world development, Cursor and Google Antigravity excel in different ways depending on your workflow and project needs. When choosing a tool, consider whether speed, experimentation, or reliability is your priority. I evaluated which tool performs best in the most common real-world scenarios:
