Hey everyone,

I wanted to drop a quick update on Building Serverless Applications with WebAssembly & Spin.

Honestly, I’m really happy with how the book is shaping up right now. I’ve been sinking a lot of late-evening and early-morning hours into refining chapters, restructuring sections, and proofreading the code examples to ensure it’s as hands-on and practical as possible. It’s a labor of love, but seeing it come together makes every late night worth it.

Because of the sheer amount of work, testing, and care going into this content, I want to price the book in a way that reflects its true value. Under Leanpub’s flexible pricing model, I’m planning to set the suggested range somewhere between $17.99 and $24.99, letting you choose what you want to pay at checkout. I feel good about this range for the value it delivers.

However, there’s one challenge I’m actively trying to solve before launching: global accessibility.

The WebAssembly, Spin, and Rust communities are truly global. But a $18 price tag carries vastly different weight depending on where you live. In some regions, $18 is a casual lunch; in others, it’s enough to feed a family for days or weeks. I don’t want this book to be exclusive to developers in high-income economies.

Since Leanpub doesn’t natively support automatic PPP (Purchasing Power Parity) or regional pricing, I’m looking at setting up a simple, honor-system request process. The idea is simple: If you’re based in an eligible region, you fill out a short form (maybe linking your LinkedIn or GitHub profile to verify your location), and I’ll send you a custom Leanpub discount code to make the book genuinely affordable for your local economy.

Before I wrapping this up, I’d like to share the tiers I’m currently aiming for:

  • Tier 1: High Purchasing Power (Full Price / $17.99–$24.99)
    • Regions: North America, Western/Northern Europe, Australia, New Zealand, Japan, Singapore, UAE, Qatar.
  • Tier 2: Moderate PPP Discount (~50% Off / ~$8.99)
    • Regions: Eastern Europe (Poland, Romania, Hungary), Latin America (Brazil, Mexico, Chile, Argentina), Parts of South East Asia (Malaysia, Thailand).
  • Tier 3: Maximum PPP Discount (~70–80% Off / ~$4.99–$6.99)
    • Regions: South Asia (India, Pakistan, Bangladesh), Sub-Saharan Africa (Nigeria, Kenya, Ghana), Southeast Asia (Indonesia, Vietnam, Philippines), Central America.

What do you think of this approach? If you live in or work with developers in Tier 2 or Tier 3 regions, do these discounted tiers feel fair and accessible for your local market? Drop your thoughts in the comments—I’d love to fine-tune this before launch!
