WebAssembly in 2025: Beyond the Browser

🎯 What Is WebAssembly?

WebAssembly (WASM) is a binary format that runs code at near-native speed. It started in browsers but is moving everywhere.

✅ Where It's Showing Up

1. Server-Side

WASM is fast and secure. Perfect for serverless functions, plugins, and sandboxed code execution.

2. Edge Computing

Run code at the edge with WASM. Faster than containers, more secure than native code.

3. Plugins and Extensions

Many apps use WASM for plugins. Fast, safe, and portable across platforms.

4. IoT and Embedded

WASM is showing up in IoT devices. Small, fast, and secure.

💡 Why It Matters

WASM gives you:

• Performance: Near-native speed
• Security: Sandboxed execution
• Portability: Run anywhere WASM runs
• Size: Smaller than containers

⚠️ Limitations

WASM isn't perfect:

• Still evolving (WASI, threading, etc.)
• Tooling is improving but not mature
• Not everything needs WASM

💭 My Take

WASM is finding its place beyond browsers. For serverless, edge computing, and plugins, it's a great fit.

Watch this space. WASM is going to be big.
