Google Antigravity vs Kilo Code (2026)

Google Antigravity

by Google

Kilo Code

by Anaconda

Pros

• ✓Runs several agents in parallel and reports through Artifacts such as plans, walkthroughs, screenshots and browser recordings, which developers can comment on while the agent keeps working.
• ✓Works from a desktop agent manager, a standalone IDE, a CLI, a Python SDK, and extensions for Visual Studio Code, Visual Studio, JetBrains IDEs, Zed and Xcode, plus Eclipse in preview.
• ✓Google Antigravity's free individual tier includes Gemini 3.8 Flash, Claude Sonnet 4.6, Claude Opus 4.6 and GPT-OSS 120B, with unlimited Tab completions.
• ✓Connects to MCP servers through an MCP Store listing more than 70, and runs terminal commands in a sandbox under a configurable permission system.

Limitations

• –Paid tiers are Google AI subscriptions, Pro at $19.99 per month and Ultra from $99.99, with usage set by quota refreshes and weekly limits rather than a published request count.
• –Google Antigravity does not support bring-your-own API keys, Gemini 4 Argon is not on the free plan, and GPT-OSS 120B is not available on the Enterprise plan.
• –On individual plans Google may use interactions to improve its products and models, and human reviewers may see them, unless the user opts out in settings.
• –Available to personal Google accounts for people aged 18 or over in approved countries, and enterprise sign-in for JetBrains, Zed, Xcode and Eclipse is in preview.

Pros

• ✓Open-source MIT-licensed and model-agnostic with 500+ models: connect any provider through BYOK with no markup, or use Kilo Pass managed inference from $19 per month. 27.8k GitHub stars and 5M+ users validate broad developer adoption.
• ✓Multi-mode architecture with parallel agents across 6+ surfaces: Architect, Code, Debug, Ask, and Orchestrator modes handle planning and execution as separate concerns with subagent delegation across concurrent git worktrees. Cloud Agents, Slack, and Code Reviewer extend beyond IDE-only workflows.
• ✓Trusted by developers at Meta, Amazon, Airbnb, PayPal, Square, and Red Hat with $8M seed funding and Product Hunt #1 Open Source Product of the Month award. More than 10 trillion tokens are processed across the platform every month.
• ✓EU data residency and provider control: the EU page documents EU-hosted inference routing, an approved-provider list, and admin restriction of unsupported routes. Kilo Mobile for iOS and Android extends agent sessions beyond the desktop, and an MCP marketplace collects community-contributed servers.

Limitations

• –SSO, SCIM, audit logs and SLAs come with the custom-priced Enterprise plan, while Teams at $15 per user per month covers usage analytics, shared agents and centralized billing.
• –Advanced features such as Memory Bank, custom modes and MCP tool configuration take setup and tuning beyond the default install.
• –Local model performance depends heavily on available hardware: expect uneven results without sufficient GPU compute for larger open-source LLMs, which limits local-first deployments on standard developer machines.
• –Code sent through Kilo Gateway can reach model providers that use prompts for training: an organization-level code training opt-out and a provider data-policy filter are available, but the setting that hides prompt-training models is disabled by default.
• –Review sentiment splits sharply by corpus: its rating on the VS Code Marketplace, by far the largest independent review base, sits well below its G2 and Product Hunt scores, which rest on much smaller samples.
