Best Practices & Pro Tips
Secure Your Keys
Never commit API keys in code. Always use environment variables. Rotate keys periodically. Enable 2FA on all accounts. Restrict Gemini keys to the Generative Language API only.
Version Control Wisely
Commit often with descriptive messages. Create branches for major changes. Tag production releases. Keep your commit history clean.
Mobile-First Design
Design for small screens first. Test on real devices, not just emulators. Touch targets must be at least 44×44 px.
Optimize Performance
Minimize large dependencies. Compress images before use. Use lazy loading for heavy components. Monitor Vercel bandwidth in your dashboard.
Accessibility
Use semantic HTML. Ensure sufficient color contrast. Add alt text to all images. Show loading states for AI responses.
Monitor & Maintain
Check the AI Studio API Keys page for usage and blocked-key notices. Set billing alerts if you attach a Cloud project. Review GitHub security alerts. Update dependencies regularly.
Free Tier Limits
| Service | Free Tier Includes |
|---|---|
| Google AI Studio / Gemini API | Free API access for development and testing at published rate limits — check ai.google.dev/pricing for the current per-model limits, since they vary by model and change over time. No billing setup required for basic use. |
| Vercel (Hobby plan) | Roughly 100 GB bandwidth/month · around 1 million function invocations · automatic HTTPS · unlimited deployments — for non-commercial personal projects only. Confirm current numbers at vercel.com/docs/limits before relying on them. |
| GitHub (Free plan) | Unlimited public repositories · 2,000 GitHub Actions minutes/month on private repos (public repos are unmetered) · private repos with a reduced feature set · GitHub Pages on public repos. |
Free tiers change often. Bandwidth caps, invocation limits, and commercial-use rules on platforms like Vercel and pricing on the Gemini API have shifted more than once in the past year. Treat the numbers above as a starting point and re-check each provider's own docs before you scale past a hobby project.
