## Google Antigravity limitations

- Pricing page gives no numeric rate limits or credit amounts, so quotas are hard to predict.
- Prices for Google AI Pro and Ultra are not shown on the Antigravity pricing page.
- Weekly and five-hour limits apply, with Gemini and Claude/GPT usage tracked separately.
- Product surfaces and release cadence are fast-moving, and some enterprise IDE features are still in Preview.

## Opera Neon strengths

- Combines chat, browser actions, research and content creation in one browser rather than a separate extension.
- Neon Do shows its plan and actions in real time and can be paused or taken over.
- Wide model choice across OpenAI, Anthropic, Google, xAI and open-weight models on the Standard plan.
- MCP connector and CLI let external agents such as Claude Code or n8n use a live browser session.
- Credentials, passwords and card details are stated to stay on the device, and Opera says it does not train on user data.
- Free VPN and ad blocker are included in the browser.

## Opera Neon limitations

- Full agentic features need the $19.90 per month Standard plan, higher than many AI add-ons.
- Windows and macOS only; no Linux, iOS or Android version yet.
- Neon Do uses cloud LLMs to plan, and page content is sent to Opera and OpenAI servers with 365-day retention.
- Opera itself calls Neon an experimental agentic browser, so behaviour and plan limits may change.
