One runtime, many features
More than a runtime, Wasmer equips you with features for cool runnings so you win the race.
Metering
Add a limit to the instructions that you want to run, so you can always stop the program after certain consumption, deterministically.
Platform agnostic
Wasmer runs in any platform. From iOS to Android, from Windows to macOS or Linux. From the server to the browser.
Headless mode
Wasmer can run in completely headless mode. Just use the slimmest Wasmer and get things rolling!
Chipset support
Wasmer can run programs in almost any chipset out there: from the typical Intel x86_64 to the new M1 or even RISC-V.
We got your back-end
From development, to production to Blockchains and even the browser, Wasmer has you covered.
