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.

Kilo Code

Pros

  • MIT-licensed and open source, with a public GitHub repository of more than 27,000 stars.
  • Access to 500+ models across 60+ providers with no stated inference markup.
  • Works in VS Code, JetBrains and the terminal, plus cloud agents, Slack and mobile.
  • Supports bring-your-own-key and local models, which avoids lock-in to one provider.
  • Teams plan is $15 per user per month with shared agents and analytics.

Cons

  • Costs are usage-based, so spend is less predictable than a flat subscription.
  • A 5% processing fee applies to credit purchases.
  • Trustpilot reviewers report billing and refund disputes, including an unexpected renewal charge and a declined refund on purchased credits.
  • The desktop app is in beta, and some reviewers cite bugs and rate-limit issues.
