Pricing Claude Code vs Kiro vs Antigravity
In 2026, the cost of these tools for a senior developer depends heavily on the "credits" or "tokens" consumed. Professional usage for a 40-hour week typically exceeds basic free tiers, requiring Pro or Power/Max subscriptions to avoid throttling.
Claude Code (Anthropic)
A high-speed, terminal-centric "agentic coding tool" that acts as a thin wrapper around Claude models. It excels at deep codebase comprehension, navigating complex monorepos, and automating Git/GitHub workflows directly from the command line.
Known for its massive 200,000-token context window, making it the "Codebase Whisperer" for large-scale enterprise projects.
Monthly Cost:
- Pro Tier: $20/month. Sufficient for light feature work (~10-40 prompts per 5 hours), but a full-time senior dev on a large codebase will likely hit limits.
- Max Tier: $100 – $200/month. This is the realistic choice for full-time work, providing 5x to 20x higher usage limits and priority access to the top-tier Claude 4.5 Opus model.
Project Fit:
- Adding Features: Highly efficient; its large context window excels at understanding existing complex codebases.
- New App: Excellent for logic and backend, but since it lacks a GUI, you may still need to pay for a separate IDE like Cursor or Windsurf for visual UI work.
Kiro (AWS)
A "spec-driven development" (SDD) IDE and CLI. It focuses on turning natural language prompts into detailed technical specifications, system designs, and documentation before writing any code.
It is highly opinionated about structure; it enforces discipline by requiring a design plan, making it a "force multiplier" for engineering rigor.
Kiro uses a unique "credit" system that distinguishes between "vibe requests" (general chat) and "spec requests" (heavy architectural planning).
Monthly Cost:
- Pro/Pro+ Tier: $20 – $40/month. Includes 1,000 to 2,000 credits.
- Power Tier: $200/month (10,000 credits).
- The "Full-Time" Reality: For 40 hours/week, heavy users have reported costs reaching $550 – $1,950/month due to overages ($0.04 per credit) if they don't use the high-tier "Power" plan.
Project Fit:
- Adding Features: Good for ensuring new features follow existing documentation and specs.
- New App: The best choice for starting from scratch because of its "Spec-Driven Development" (SDD) focus, which forces high-quality architecture design before coding.
Antigravity (Google)
Antigravity is Google's agent-first platform that manages multiple AI agents in parallel.
An "agent-first" development platform and "Mission Control" for managing multiple autonomous agents simultaneously. It can operate across the editor, terminal, and a native browser, allowing agents to self-verify UI changes and record video proof of their work.
Its Agent Manager allows for "multitasking on steroids," where a user can dispatch multiple agents to work on separate bugs or features in parallel across different workspaces.
Monthly Cost:
- Individual/Preview Tier: $0/month (currently free in public preview for 2026).
- Predicted/Future Tiers: Expect $20 – $40/month for professional team plans once it exits preview.
Project Fit:
- Adding Features: Its "Agent Manager" allows a senior dev to fix multiple bugs or add small features simultaneously across different branches.
- New App: Excellent for rapid prototyping; its native browser integration allows agents to self-verify UI changes in real-time.
Cost Summary for 40-Hour/Week Development
| Tool | Monthly Cost (Pro Level) | Best Use Case |
|---|---|---|
| Claude Code | $100 – $200 (Max Tier) | Deep feature work on massive, existing codebases |
| Kiro | $200+ (Power Tier + Overages) | New builds requiring strict architectural specs |
| Antigravity | $0 (Preview) / $40 (Est. Pro) | High-speed prototyping and multi-tasking |
