Features & Specs

  1. Cross-platform

    Wasmer enables running WebAssembly modules on various platforms like Linux, macOS, and Windows, enhancing portability and flexibility for developers.

  2. Performance

    Wasmer is capable of near-native execution speeds, allowing applications to run efficiently by leveraging just-in-time (JIT) or ahead-of-time (AOT) compilation.

  3. Language Agnostic

    Wasmer supports multiple programming languages, enabling developers to write in their preferred language and compile it to WebAssembly, enhancing inclusivity and ease of use.

  4. Sandboxing

    With Wasmer, applications can run in a secure sandboxed environment, reducing potential security risks often associated with executing untrusted code.

  5. Integration

    Wasmer can be embedded into different host languages like JavaScript, Rust, Python, etc., allowing seamless integration into existing projects and workflows.

  • Ask HN: Who is hiring? (April 2026)
    Wasmer (YC S19) | https://wasmer.io/ | Multiple Roles | Remote (EU) or Office (US) | Full-time We are building the next generation of infrastructure for AI without Docker containers, but with a better container technology based on WebAssembly! We are hiring for:
      * Rust Engineer.

  • IoT Architectures Under Pressure: hosting a portable firmware (Part 3)
    Several WASM runtimes are available to execute our code. In this example, we'll use Wasmer, though other options exist. If we compile AOT (Ahead-of-Time), we donโ€™t even need a runtime at all! - Source: dev.to / about 1 year ago
  • Hello world from a WASM module in a static binary
    I decided initially to use Wasmer and ended filing a question on their repository because their own native binary build command doesn't work as expected. - Source: dev.to / over 1 year ago
  • WebAssembly: A promising technology that is quietly being enshitified
    I applaud the author on how clear he made the argument. Note: I work at Wasmer (https://wasmer.io), a WebAssembly runtime. - Source: Hacker News / about 2 years ago
  • Bebop v3: a fast, modern replacement to Protocol Buffers
    This is awesome. I'd love to have upstream support in Wasmer ( https://wasmer.io ). - Source: Hacker News / over 2 years ago
  • Show HN: dockerc โ€“ Docker image to static executable "compiler"
    Unfortunately cosmopolitan wouldn't work for dockerc. Cosmopolitan works as long as you only use it but container runtimes require additional features. Also containers contain arbitrary executables so not sure how that would work either... As for WASM, this is already possible using container2wasm[0] and wasmer[1]'s ability to generate static binaries.

  • Howto: WASM runtimes in Docker / Colima
    I could not find any guide how to add WASM container capability to Docker running on Colima. This guide provides a few Colima templates for exactly this, which adds WasmEdge, Wasmtime and Wasmer runtime types. - Source: dev.to / over 2 years ago
  • Prettier $20k Bounty was Claimed
    The Biome team has been incredibly fast on solving the challenge and achieving 95% compatibility with Prettier [1] Just as a note, as it was not mentioned in the article, Wasmer [2] also participated with a $2,500 bounty to compile Biome to WASIX [3], and it has been awesome to see how their team has been working to achieve this as well... Hopefully we'll get Biome running in Wasmer soon! Keep up the great work!!... - Source: Hacker News / over 2 years ago
  • The Curse of Docker
    It's funny how WebAssembly can help overcome most of the issues mentioned on the blogpost (packaging, configuration, portability) if addressed properly. That's the main reason Wasmer [1] was created :) [1] https://wasmer.io. - Source: Hacker News / over 2 years ago
  • Bring garbage collected programming languages efficiently to WebAssembly
    Thanks for the mention to Wasmer. I'll put here a link in case is useful for future readers: https://wasmer.io/. - Source: Hacker News / almost 3 years ago

    It's great to see more use cases of Wasmer [1] out there. I'm excited for what's coming next on this front :) [1] https://wasmer.io/. - Source: Hacker News / about 3 years ago
  • Microsoft rewrote Q compiler in Rust
    I respect the hustle. Sorry for not mentioning https://wasmer.io. - Source: Hacker News / about 3 years ago
  • Dotnet wasmer
    What's the chance a version of dotnet could be compiled to work on https://wasmer.io/ straight up? No OS needed per say. Source: about 3 years ago
  • Terminal app built over WebGPU, WebAssembly and Rust
    I can't wait to have the terminal fully compiling to WebAssembly and runnable in Wasmer! [1] [2] [1]: https://wasmer.io/. - Source: Hacker News / about 3 years ago
  • Fast Matrix Math in JS 2: WASM
    To actually compile this we can use a tool called WABT (WebAssembly Binary Toolkit). It's basically a mess that requires CMake and I couldn't get it to run on WSL and I wasn't going to install MinGW. Instead there's a nice tool called WAPM from Wasmer which works like npm for webassembly packages and since it's been compiled down to webassembly we can run it in any environment. In fact we don't even need to add... - Source: dev.to / about 3 years ago
  • ROS2: Yocto vs. Docker
    See wasmtime or wasmer Https://wasmtime.dev/ Https://wasmer.io/ Wasmer even advertises its use on embedded platforms, but I have not tried this on embedded devices like STM f7 etc. Source: over 3 years ago
  • Ruby Adds Support for WebAssembly: What is WebAssembly and how it benefits Ruby devs?
    Running a Wasm application outside the browser requires an appropriate runtime that implements the WebAssembly VM and provides interfaces to the underlying system. There are a few competing solutions in this field, the most popular being wasmtime, wasmer, and WAMR. - Source: dev.to / over 3 years ago

  • Dozens of malicious PyPI packages discovered targeting developers
    That's the main reason we should start using WebAssembly for distributing and using packages. Shamless plug: Wasmer [1] and WAPM [2] could help a lot on this quest! [1]: https://wasmer.io/ [2]: https://wapm.io/. - Source: Hacker News / almost 4 years ago
