Felix Zeller

Felix Zeller is an independent developer whose open-source work centers on tools that quietly extend the capabilities of plain-text workflows. His flagship project, Markdown-Oxide, re-imagines a personal knowledge base as a standards-compliant Language Server: the same protocol that powers IDE autocompletion is repurposed so that any LSP-aware editor—Neovim, Zed, Helix, VS Code—gains instantaneous backlinks, tag indexing, workspace-wide search, and graph navigation inside ordinary Markdown folders. No proprietary database or web service is required; the entire system lives as a lightweight background process that watches files and answers queries in milliseconds. Because it speaks LSP, users keep their preferred keybindings, themes, and plug-ins while adding modern PKM features such as hover previews, diagnostics for broken links, and fuzzy finding across note titles. Typical use cases range from academic research clusters, software design wikis, and Zettelkasten note collections to developer playbooks and static-site documentation. The codebase is written in Rust, so a single binary runs on Windows, macOS, and Linux without further dependencies, making it easy to sync a knowledge graph through Git or cloud drives. Markdown-Oxide is offered for free on get.nero.com, where the package is pulled from the publisher’s official GitHub releases, delivered through the trusted winget channel, always updated to the newest build, and ready for unattended batch installation alongside other Windows utilities.
