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.
FreemiumCodeium launched with a genuinely free tier for individual developers — unlimited code completions, chat, and search across 70+ languages and 40+ IDEs with no time limit or credit cap. Enterprise plans (custom pricing) added on-premises deployment, SOC 2 compliance, SSO, and zero code retention. After launching the Windsurf Editor in November 2024, the company introduced paid tiers: Free ($0) with unlimited Tab autocomplete and a light agent quota; Pro ($15/month, later raised to $20/month in March 2026) with full model access, standard refreshing agent quota, and Cascade; Teams ($30/user/month); and Enterprise ($60/user/month) with SSO, 1,000 prompt credits, and enhanced security. Following Cognition AI's acquisition and the June 2026 rebrand to Devin Desktop, pricing is now managed under Cognition's Devin plan structure: Free ($0), Pro ($20/month), Max ($200/month), Teams ($80/month + $40/seat), and Enterprise (custom). The codeium.com/pricing URL now redirects to devin.ai/pricing.

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

Codeium Pros & Cons

Pros

  • Genuinely unlimited free tier for individual developers — no credit limits or trial expiry
  • Broadest IDE coverage of any AI coding tool with 40+ editor integrations at launch
  • Rapid iteration: went from plugin to agentic IDE and $100M ARR in under 3 years
  • Enterprise-grade security with on-prem/VPC deployment, SOC 2, and zero code retention options
  • Cascade/Windsurf Editor introduced flow-aware multi-file agentic coding before competitors
  • Backed by top-tier investors and reached $1.25B unicorn valuation in just 2 years

Cons

  • Rebranded twice (Codeium → Windsurf → Devin Desktop) creating confusion and instability for users
  • Original Codeium extension identity sunset — codeium.com now redirects to Devin/Cognition
  • Pro pricing rose from $15 to $20/month in March 2026, removing its budget pricing edge over Cursor
  • Cascade agent fully retired July 1, 2026 — replaced by Devin Local under new ownership
  • Heavy agentic workflows require Pro plan; free tier agent quota is limited
  • Brand owned by Cognition AI (Devin), not the original Codeium/Windsurf founding team
