Pros and cons

Google Antigravity

Pros

  • Free Individual plan with unlimited Tab completions and Command requests.
  • Offers Gemini, Claude and GPT-OSS models in one tool.
  • Parallel agents and background subagents in isolated Git worktrees.
  • Artifacts (plans, diffs, browser recordings) make agent output reviewable.
  • Available as app, CLI, IDE extensions and Python SDK on macOS, Windows and Linux.
  • Enterprise controls include SSO, VPC Service Controls and regional data residency.

Cons

  • 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

Pros

  • 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.

Cons

  • 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.
