Building bun-tastic: A Fast, High-Performance Static Site Server (OSS)

Static site hosting: speed, simplicity, and control with bun-tastic

Static websites are renowned for their speed, security, and ease of management. The JAMStack approach and builders like Hugo and Eleventy have boosted their popularity. Now, bun-tastic offers a compelling self-hosting solution for managing multiple static sites efficiently.

Traditional static site hosting options, such as AWS S3/CloudFront, Netlify, or GitHub Pages, are excellent, but they may not suit everyone's needs. For those managing numerous projects and seeking customization, bun-tastic provides a superior alternative.

What is bun-tastic?

bun-tastic is a high-performance static site server built on Bun, a fast JavaScript runtime, and leveraging an S3 API. It uses any S3-compatible object storage, ideally Tigris, for global caching, combining the benefits of AWS S3 and CloudFront without the extra setup or cost. For multi-region deployment and effortless scaling, Fly.io is recommended.

Key Features:

• Multi-site management from a single application.
• Intelligent path handling with automatic index.html resolution.
• Fast, automatic TLS certificates (with Fly.io).
• Simple JSON configuration.
• HTTP/3 support (via Fly.io).
• Brotli & zstd compression.
• Built-in monitoring (Grafana dashboard on Fly.io).
• Zero dependencies; runs on 256MB RAM.

Performance Benchmarks

bun-tastic's speed is a significant advantage. Load tests on a shared VM (256MB RAM, 1 vCPU) deployed to Fly.io in Stockholm show response times consistently under 100ms for 6KiB responses.

Technology Stack

bun-tastic leverages the power of:

• Bun's Native Capabilities: Utilizing Bun's built-in S3 client and web server for optimal performance and minimal overhead.
• HTTP/3 & Compression (with Fly.io): Ensuring modern web performance and efficient content delivery.
• Globally Distributed Object Storage (Tigris): Providing global caching for faster access times.

Why Choose bun-tastic?

For agencies, freelancers, or anyone managing multiple websites, bun-tastic offers:

1. Simplified Management: Consolidate multiple sites under a single server, each with its own domain.
2. Cost Effectiveness: Runs on minimal resources, scales to zero when idle, and benefits from Fly.io's volume-based pricing.
3. Complete Control: Customize redirects, middleware, and authentication per domain.

While potentially more expensive than some traditional solutions for single, low-traffic sites, bun-tastic's flexibility, performance, and control make it a cost-effective solution for managing multiple sites or handling higher traffic volumes. Fly.io's volume-based pricing and autoscaling capabilities can significantly reduce costs.

Frequently Asked Questions

• Is self-hosting more expensive? It depends on scale. For many sites or higher traffic, bun-tastic with Tigris and Fly.io can be more cost-effective.
• Can I use any S3-compatible storage? Yes.
