opendoc vs wordcraft
Rust-based document editors compared
opendoc and wordcraft are open-source Rust projects for working with Word documents, and both run on desktop and in browsers through WebAssembly. opendoc focuses on an embeddable document engine and local-first editing, while wordcraft is a ribbon-style word processor with desktop, CLI, and agent-driven workflows.
opendoc: Edit Word Documents with a Rust Engine
OpenDoc is an Apache-2.0 local-first Word document editor built on a deterministic Rust engine. It runs natively, headless, or in the browser through WebAssembly, and reads and writes DOCX and ODT.
wordcraft: Create Word Documents with Rust and egui
WordCraft is a Rust word processor built with emilk’s egui, offering a familiar ribbon workflow for creating and editing documents. It supports macOS, Windows, Linux, BSD and the web through WebAssembly.

Key differences
- opendoc reads and writes DOCX and ODT, while wordcraft reads and writes DOCX and imports legacy DOC files alongside a wider range of formats.
- opendoc provides an embeddable custom element, an in-process API, and a host-controlled bridge; wordcraft provides a CLI, MCP server, and JSON control channel.
- opendoc emphasizes loss-aware DOCX handling and reports content that exports cannot preserve; wordcraft emphasizes a familiar ribbon interface and desktop word-processing tasks.
- Both are Apache-2.0 licensed, while wordcraft is also available under MIT; its branding has separate terms for forks and modified versions.
- opendoc is pre-release, with unstable SDK surfaces and imperfect Word rendering; wordcraft describes itself as alpha and calls out pagination fidelity and real-world DOCX testing as remaining work.
- opendoc supports headless use and Rust document-engine workflows; wordcraft targets desktop writers and scripted or agent-driven document work. Both also offer browser builds through WebAssembly.
Choose opendoc if you…
- need an embeddable, local-first editor that opens and saves documents in the browser without a document server.
- want Rust crates for importing, editing, laying out, rendering, or exporting documents.
- need headless document preview or conversion, and can accept pre-release status and imperfect Word rendering.
Choose wordcraft if you…
- want a desktop word processor with a ribbon workflow across macOS, Windows, Linux, or BSD.
- need CLI, scripting, or MCP tools for creating, converting, inspecting, or editing documents.
- want review tools such as comments and tracked changes, and can test important DOCX files for compatibility.
