 ✨ **Simplicity**: the logic for agents fits in ~1,000 lines of code (see [agents.py](https://github.com/huggingface/smolagents/blob/main/src/smolagents/agents.py)). We kept abstractions to their minimal shape above raw code!
 
-🧑‍💻 **First-class support for Code Agents**. Our [`CodeAgent`](https://huggingface.co/docs/smolagents/reference/agents#smolagents.CodeAgent) writes its actions in code (as opposed to "agents being used to write code"). To make it secure, we support executing in sandboxed environments via [Blaxel](https://blaxel.ai), [E2B](https://e2b.dev/), [Modal](https://modal.com/), Docker, or Pyodide+Deno WebAssembly sandbox.

 Since code execution can be a serious security concern (arbitrary code execution!), **you should run agent code in a sandbox**. We support several options:
   - [E2B](https://e2b.dev/), [Blaxel](https://blaxel.ai), [Modal](https://modal.com/) — managed cloud sandboxes, simplest to set up
   - [Docker](https://www.docker.com/) — self-hosted container isolation
-  - Pyodide+Deno WebAssembly — lightweight sandbox for browser or edge environments
 
 The built-in `LocalPythonExecutor` is **not a security sandbox**. It applies some restrictions but can be bypassed and must not be used as a security boundary.

-### WebAssembly setup
-
-WebAssembly (Wasm) is a binary instruction format that allows code to be run in a safe, sandboxed environment.
-It is designed to be fast, efficient, and secure, making it an excellent choice for executing potentially untrusted code.
-
-The `WasmExecutor` uses [Pyodide](https://pyodide.org/) and [Deno](https://docs.deno.com/).
-
-#### Installation
-
-1. [Install Deno on your system](https://docs.deno.com/runtime/getting_started/installation/)
-
-#### Running your agent in WebAssembly: quick start
-
-Simply pass `executor_type="wasm"` to the agent initialization, like:
-```py
-from smolagents import InferenceClientModel, CodeAgent
-
-agent = CodeAgent(model=InferenceClientModel(), tools=[], executor_type="wasm")
-
-agent.run("Can you give me the 100th Fibonacci number?")
-```

 ### Best practices for sandboxes
 
 These key practices apply to Blaxel, E2B, and Docker sandboxes:
