FAQ
Is this the official Wasmtime download?
Yes. Every link points to an official source: github.com. AIMap does not host, repackage or modify any installer; we re-check the links on every data refresh (last 2026-10-23).
What is the latest version of Wasmtime?
v50.0.0, released 2026-10-20 (latest stable release on GitHub Releases, checked 2026-10-23).
Which Mac file should I pick?
Apple menu → About This Mac: “Apple M1/M2/M3/M4…” means Apple silicon (arm64 / aarch64); “Intel” means x64. A “universal” file runs on both.
Which Windows file should I pick?
Most PCs are x64 (Settings → System → About → “System type: 64-bit operating system, x64-based processor”). Pick ARM64 only on ARM laptops such as Snapdragon X machines. .exe/.msi are installers; .zip is a portable build you unzip and run.
How do I verify the download?
Compare the SHA-256 shown in the file table (published by GitHub for each release asset) with your file: macOS/Linux `shasum -a 256 <file>`, Windows PowerShell `Get-FileHash <file> -Algorithm SHA256`.
Is Wasmtime free?
Pricing model: Open source; licence Apache-2.0. Check the official site for current plans.
