Pricing
FreemiumGoogle Antigravity is free during its preview period for any user with a Google account. A unified AI credit system applies: credits are drawn down at API-equivalent ratios across Gemini Flash and Pro models (e.g., if Flash is 8x cheaper than Pro, you can use 8x more Flash tokens for the same credit spend).
Google AI Pro at $20/month provides additional AI Premium credits suitable for regular development use. Google AI Ultra was reduced from $250/month to $100/month for a lighter high-frequency tier, with a separate $200/month tier for the highest capacity. Add-on credits can be purchased at any time via the CLI or IDE credits panel.
For GovCloud environments, a paid Gemini Code Assist Standard ($19/user/month) or Enterprise ($45/user/month) license is required — no free tier in GovCloud. Enterprise customers access Antigravity through the Gemini Enterprise Agent Platform under Google Cloud terms with centralized admin controls and compliance features.
FreeCline itself is free and open source — there are no seat fees or subscriptions for the core agent. You pay AI inference costs directly to your chosen LLM provider (Anthropic, OpenAI, Google, etc.) with a full per-request cost breakdown shown in the UI. Cline shows every token used and every dollar spent transparently.
ClinePass ($9.99/month) is an optional managed billing subscription that provides 2–5x more usage on popular open coding models compared to standard API rates, with one-click sign-in and no need to manage API keys yourself. It is not required — BYOK (bring your own key) is always available at zero markup.
Enterprise pricing is custom and adds JetBrains extension, SSO/OIDC/SCIM, SLA, centralized billing, RBAC, team management dashboard, authentication logs, limit inference providers, dedicated support, VPC deployments, OpenTelemetry, and advanced config management.

Summary
Google's agentic AI IDE and CLI — Gemini 3, scheduled tasks, free during preview
Open-source AI coding agent — any model, your keys, full control
Google Antigravity Pros & Cons
Pros
- Built by Google with Gemini 3.1 Pro — the deepest integration with Google's most capable model and GCP ecosystem
- Free during preview with no credit card required — full feature access including agent manager and scheduled tasks
- Scheduled Tasks (cron) enable truly autonomous agents that work without any human trigger — unique among major IDE platforms
- Live voice transcription via Gemini Audio — describe complex tasks faster than typing
- IDE extensions (Aug 2026) let enterprise developers use Antigravity from VS Code and JetBrains without switching editors
- Full platform: IDE + CLI + SDK + Enterprise Agent Platform — the most complete Google developer toolchain ever shipped
Cons
- Proprietary closed-source — unlike Gemini CLI (Apache 2.0), Antigravity's source code is not publicly available
- Gemini-centric — while Claude and GPT-OSS are supported, Gemini models are prioritized; less model flexibility than Kiro or Cline
- Still in preview as of August 2026 — some enterprise and GovCloud features are new and less battle-tested than Cursor or Windsurf
- Credit-based pricing can be unpredictable for heavy users with complex agent tasks
- Requires Google account and GCP setup for enterprise access; additional procurement overhead for non-GCP organizations
- Free preview status subject to change — pricing structure may shift as product exits preview
Cline Pros & Cons
Pros
- Completely free and open source (Apache 2.0) — no seat fees, no subscriptions, no proprietary lock-in ever
- 67K+ GitHub stars and 8M+ developers — largest open-source coding agent community by any measure
- Full cost transparency at zero markup — the only major coding agent that shows exactly what you pay per request with no hidden pricing
- Model-agnostic with 12+ provider integrations — switch any time without changing workflow or losing your setup
- Plan/Act mode gives full human-in-the-loop control — approve every action or flip to autopilot when confidence is high
- Trusted by engineers at Salesforce, Oracle, Amazon, Microsoft, eBay, Visa, IBM, and LG
Cons
- BYOK means you manage your own LLM API keys and billing — can be confusing for non-technical users used to flat subscriptions
- No built-in inline autocomplete (Tab completions) — Cline is an agent, not a code-completion tool like Copilot or Tabnine
- JetBrains support is still Early Access — not as polished as the VS Code extension
- Some engineers joining OpenAI's Codex team in January 2026 raised community concerns about long-term momentum (Cline confirmed no acquisition and remains independent)
- Enterprise features (SSO, RBAC, JetBrains, SLA) require a custom sales contract — no self-serve team plan available
