Gatsby
React-based static site generator for blazing fast websites
Strengths
- +Completely free and open source framework

Feature Comparison
| Feature | ||
|---|---|---|
| Primary Use Case | Static site generation framework | Cloud application hosting platform |
| Pricing Model | Free (open source) | $5-$250+/month per dyno |
| Hosting Included | No - requires separate hosting | Yes - full hosting platform |
| Backend Support | No - static sites only | Yes - full backend support |
| Database Support | Build-time only via GraphQL | Yes - Postgres, Redis, MySQL add-ons |
| Deployment Method | Build locally or CI/CD, deploy to CDN | Git push to Heroku remote |
| Performance | Excellent - pre-rendered static files | Good - depends on dyno tier |
| Scaling | Automatic via CDN | Manual dyno scaling |
| Build Time | Required for every content change | Only on code deployment |
| Dynamic Content | Limited - requires client-side JS or rebuilds | Full support for dynamic applications |

The Verdict
Gatsby and Heroku serve fundamentally different purposes and aren't direct competitors. Gatsby is a free static site generator ideal for content-focused sites that prioritize performance and SEO, while Heroku is a paid platform-as-a-service for hosting dynamic applications with backends and databases. Choose Gatsby for static content sites where you'll handle hosting separately, or Heroku when you need a complete hosting solution for full-stack applications with server-side logic.
