Tidemark

Tidemark is a browser-hosted RISC-V Linux userland environment.

It lets applications run command-line tools, language runtimes, package-backed file layers, and terminal-style workflows inside WebAssembly and browser worker infrastructure.

Repositories

kernelRISC-V execution, ELF loading, Linux userland syscalls, memory, filesystem, process, thread, signal, pipe, and socket behavior.
runtimeBrowser and Node worker orchestration around the kernel WebAssembly module, including process lifecycle, stdio, filesystem snapshots, and host bridge integration.
sdkApplication-facing API for creating runtimes, applying file layers, running commands, installing package layers, and attaching terminals.
docsPublic architecture and compatibility documentation.

Architecture

Tidemark is an application-embedded guest execution environment for browser and worker hosts. It is not just CPU emulation: it combines guest execution, filesystem state, process orchestration, stdio, network bridge hooks, and SDK-level provisioning.
