It doesn't have browser support yet because it's WASI-based, so there are a few more steps compared to Emscripten (two different ways to build for WebAssembly). But networking is supposed to work, did you have trouble with it?

With RISC‑V emulation we get the virtual hardware components we need to boot Linux like MMU, registers etc. So a GCC WASM backend could definitely help, but I'm not sure it could replace the whole emulation layer.

Show HN: Vpod – Tiny Linux sandbox running in WASM

mavdol04 — Wed, 17 Jun 2026 16:41:12 +0000

Hi HN,

I spent the last few months reading the RISC‑V specification to build the lightest possible sandboxes. The idea behind a vpod is to quickly spin up a Linux sandbox from snapshots (Alpine by default) without any setup or subsystem required.

The trade-off for portability and security is raw CPU speed. So we don't expect it to match native workloads with Python or pip, for example.

More info is in the README https://github.com/capsulerun/vpod

Happy to answer any questions!

It's a bit of a cheat, but you can hit 0.00% every time. Just measure the bar length, then cross-multiply. :)

Example: bar is 1250px, max is 2100, number is 376 → (1250 × 376) / 2100 ≈ 223.8px from the start, that's the 0.00%.

Working on a RISC-V emulator targeting Wasm. Is RVV 1.0 stable enough to be worth implementing, or would Zve32f/Zve64d already cover most use cases ?

Nice, what are you building exactly ?

Show HN: Capsule Bash – Sandboxed Bash for Agents

mavdol04 — Mon, 04 May 2026 14:49:16 +0000

I've always felt that existing Bash wasn't adapted for agents. It gives way too much freedom and not enough feedback to enrich the context after each command.

I ended up building this TypeScript-based sandboxed Bash. If we compare it to other alternatives, it is divided into two layers:

- The core, with all the Bash commands and the operator logic.

- The runtime, a pluggable part that manages code execution in the sandbox. There's a Wasm runtime available based on a Rust runtime I launched a few months ago. [1]

In practice, the core calls the runtime to execute code and get back structured information from the sandbox, including exact filesystem changes (what was created, modified or deleted) and direct feedback in stdout.

I added commonly used commands, including `python3 -c` and `node -e`, but if you find an edge case where the current commands aren't enough, let me know.

I am in the EU timezone and had some minor issues recently with GitHub as well, but it never lasts very long.

mavdol04 — Tue, 21 Apr 2026 19:06:54 +0000

The worst that could happen is having your credentials stolen. It’s an LLM architectural flaw, so it has to be at the tools level so the only way to prevent it is still sandboxing in my opinion. Or at least sandboxing the tools themselves

I think a shared array just avoids the copy, not the serialization which is the main problem as they showed with serde-wasm-bindgen test

That’s great, but it can’t be used in production because it’s not available for Linux (so no AWS, no GCP, etc.) and requires Docker Desktop. Still nice for experimenting, though.

I mean standardizing on an x86 subset would replace wasm's native portability with a kind of 'emulated' compatibility, and this is one of wasm's strengths. If we do that, non-x86 hardware(mobile etc.) will pay the translation tax. So, keeping Wasm agnostic makes more sense anyway.
