About Wasmer
Wasmer runs programs compiled to WebAssembly inside small, fast sandboxes. You can run them on your own machine or deploy them to its cloud edge.
What it does
Wasmer provides a command line tool and a registry of ready-to-run packages, such as Python, Node.js, SQLite and FFmpeg. You can run a package with a single command, or deploy an app to Wasmer Edge. The company states that its sandboxes start faster and use less memory than typical virtual machines.
Key features
- Run a package with one command
- Browse a registry of ready-to-run software
- Use the CLI, Node.js, Python or a browser
- Deploy web apps and templates to the edge
- Small sandboxes for apps and AI agents
Who it's for
Wasmer suits backend developers who want lightweight, isolated runtimes for apps or scripts. It also fits platform teams who run AI agents and need quick, low-cost sandboxes. Developers who only want to try WebAssembly can start with the browser runner.
Pricing and good to know
The site invites visitors to deploy for free and lists a pricing page with paid options. The CLI installs with a shell script, so it runs on Linux and macOS terminals. Check the registry for the packages your project needs before you move it over.
