Hello Fastly Community! :waving_hand:

We’re thrilled to announce the Beta release of the official C++ SDK for Fastly Compute!

Why C++ at the Edge?

Our SDK combines the gold standard performance of C++ with Fastly’s WebAssembly (Wasm) runtime, offering:

  • Blazing-fast execution: Achieve microsecond cold-start times with low-level, efficient Wasm bytecode.

  • Memory-Safe C++: Leverage the isolation of Wasm’s sandbox for safer edge applications.

  • Lower operational costs: Use CPU resources efficiently while maintaining top-tier performance.

Cool Use Cases

Here’s how you can deploy C++ logic to the edge:
:video_game: Gaming: Build latency-critical features like matchmaking APIs and real-time player state synchronization.
:bar_chart: IoT & High-Tech: Process vast telemetry streams and run predictive maintenance calculations directly at the edge.
:movie_camera: Interactive Media: Implement advanced cryptography, real-time ad-stitching, or compression algorithms.

What Does the SDK Offer?

This SDK is designed to feel familiar to seasoned C++ engineers, with industry-standard bindings to Fastly’s powerful edge computing tools, such as KV Stores and Config Stores. It also supports polyglot development, allowing seamless integration of C++ with other languages like Rust or JavaScript.
