How to not go broke on Vercel

Why is Vercel bandwidth expensive?

Vercel's bandwidth costs are notably high due to the premium infrastructure they offer.

• CDN Usage: Vercel uses a Content Delivery Network to distribute files. This ensures rapid delivery to users, but the cost is significantly higher compared to other providers.

• Quality Service: By using high-quality CDNs, Vercel provides a fast experience for small assets, like favicons. However, for larger files, this can become an expensive proposition.

• Comparisons: Many compare Vercel's pricing to providers like Hetzner. However, it's crucial to understand that Vercel's CDN includes features that justify the cost for certain use cases.

To reduce costs:

• Host Large Files Elsewhere: Incorporate external services like AWS S3 or Cloudflare's R2 for storing large assets.

• Use UploadThing: This is a new service that allows you to store assets without incurring egress fees.

• Leverage Vercel's Blob: Another option is Vercel's own product which allows for a similar solution to embrace lower costs.

Optimize your setup wisely and potentially eliminate high bandwidth fees. Such strategies align with Vercel's innovative approaches as noted in insights on Vercel's serverless technology.

How can image optimization impact your Vercel bill?

Vercel's image optimization can drastically affect expenses.

Poor practices can lead to unexpected costs.

Consider these aspects:

• Optimization Costs: On a free plan, 1,000 image optimizations are included. Beyond that, each set costs $5 per 1,000. Using the pro tier, you get 5,000 free. Proper management is crucial due to costs.

• Best Practices for Savings:

  • Use the Next Image component wisely to compress images.

  • Host images externally on services like S3 or R2.

  • Use restricted URL paths to prevent abuse.

Implementing these practices can significantly reduce costs and maintain a more budget-friendly approach.

What are the common pitfalls in serverless function usage?

Serverless functions can lead to high costs if not used wisely.

Common mistakes include unnecessary database calls. For instance, if each call takes 50 milliseconds and you block sequentially, this accumulates to lengthy processing times. Multiple blocking calls increase both time and costs.

To optimize queries:

• Run Database Queries Concurrently: Use promises to execute non-dependent tasks simultaneously.

• Use Efficient Data Models: Consolidate related queries into one database call to reduce interaction time.

To reduce serverless compute time, consider caching. By storing results of expensive computations, future requests can retrieve data quickly without repetitive processing, lowering costs significantly. When data becomes outdated, ensure caches are invalidated efficiently to maintain accuracy.

For more insights on avoiding various pitfalls, including those in coding, ensure your approach integrates best practices outlined in resources like how to avoid common coding pitfalls.

How can caching reduce Vercel costs?

Caching plays a crucial role in minimizing compute costs by decreasing redundant server requests. It stores the outcomes of costly computations, allowing future requests to access precomputed data without extra processing.

Implement caching effectively:

• Utilize unstable cache functions to wrap expensive database queries. This ensures computations are only carried out once per data change, not per user request.

const cachedPostFetcher = unstable_cache(() => {
  // database query
}, ['tag']);

• When the data changes, invalidate caches to maintain accuracy. Use revalidateTag to refresh data, preventing stale content.

async function leaveComment() {
  // code to add a comment
  revalidateTag('post');
}

By reducing repeat computation, caching significantly lowers expenses and boosts performance. Ultimately, caching complements strategies to reduce overall Vercel cost optimization and should be carefully planned in development workflows. For a broader understanding of caching dynamics, explore how 'Use Cache' is changing the game in Next.js advancements.

When should you use static vs dynamic pages?

Static pages shine when content remains consistent and doesn't require server-side computation. They reduce hosting costs by serving pre-rendered HTML, providing faster load times and enhancing user experience. A prime example includes terms of service or blog entries, where content rarely changes.

In contrast, dynamic pages efficiently handle real-time interactions and personalized content. They are ideal for user dashboards, e-commerce sites, or news feeds where content updates frequently. However, these pages incur higher costs due to server-side computing needs.

To optimize performance and cost, evaluate web content's nature before deciding. Static pages excel at speed and cost-effectiveness. Dynamic ones offer interactivity at a price.

What are alternative image optimization solutions?

When seeking image optimization solutions outside Vercel, several options exist with varying benefits and limitations:

• Cloudflare: Known for its reliability, Cloudflare offers image optimization services. It provides cost-effective solutions, though some users report complexities in setting up.

• AWS S3: A popular choice for hosting and optimizing images. AWS S3 integrates well with other services but may result in higher costs if not managed properly.

• Cloudinary: Offers comprehensive image management with a range of optimization features. It delivers a user-friendly interface but sometimes can be on the pricier side.

• ImageEngine: This service enhances image delivery speeds and reduces sizes. It emphasizes speed but could be overkill for smaller projects.

Choosing the right tool depends on specific needs and budget constraints. Always assess the scalability and integration potential with existing workflows before committing. For additional strategies on improving website speed and performance, explore key insights on Next.js optimizations.

How to manage your Vercel spending?

Managing spending on Vercel requires careful monitoring and proactive measures.

To prevent unexpected bills, follow these steps:

1. Set a Spend Limit
   Navigate to the Billing section in your Vercel dashboard. Set a specific monthly spend limit. This cap ensures your expenses don't exceed your budget.

2. Enable Notifications
   Opt into notifications to stay informed as spending approaches budget limits. This way, you’re alerted well before approaching your set limit.

3. Monitor Usage Regularly
   Regularly review the analytics and billing details to track your usage patterns. Identify any unexpected spikes or consistent high usage that may need addressing.

4. Optimize Usage
   Implement the best practices for serverless function use, caching, and image optimization covered earlier in the article. Reducing compute time and bandwidth usage directly impacts costs.

5. Review and Adjust
   Evaluate usage and make necessary adjustments to your applications or infrastructure to remain cost-effective.

By following these practices, you can ensure more predictable and manageable expenses, aligning with the broader goal of reduce Vercel expenses.
