Cost-Saving Strategies

Maximize your budget with these techniques

Stack Tools Strategically

Use Antigravity (free) for infrastructure + Cursor Pro ($20) for UI work = $20/month for full coverage instead of $100+ on a single tool.

Batch Your Sessions

Claude Code's 5-hour usage windows reset automatically. Plan intensive sessions, then let it reset. Don't spread thin usage across the day.

Use Prompt Caching

Claude API users save up to 90% with prompt caching. Batch API saves 50%. Use --cache flags when available.

Prototype Locally First

Use Ollama for initial exploration and prototyping. Switch to paid tools only when you need their specific capabilities.

Right-Size Your Model

Use cheaper models (Haiku, GPT-4.1-mini) for simple tasks. Save Opus/GPT-4.1 for complex reasoning that actually needs it.

Monitor Usage Carefully

Copilot shows premium request usage. Cursor shows credit consumption. Check weekly to avoid surprise overages at $0.04/request.

Ready to Start?

Here's exactly where to begin based on your project type:

Micro SaaS

Start with Google Antigravity (free). It can handle your entire stack from landing page to Stripe integration.

Antigravity
iOS App

Install GitHub Copilot for Xcode ($10/mo). Native integration means you stay in Xcode the whole time.

Copilot
Containerized

Google Antigravity's 1M token context can hold your entire infra. Free tier handles most hobby projects.

Antigravity
Single Page App

Download Cursor ($20/mo). Cmd+K inline editing creates the fastest React/Vue iteration loop.
