Filesystem-first editing
Open a file or folder through native dialogs and edit the original source directly. Save and Save As write Markdown or MDX rather than converting documents into an app-specific format.
Fulvid
Fulvid is an open-source Markdown and MDX editor for Linux, Windows, and macOS. Edit local files, preview inert HTML, and export HTML.
Local Markdown and MDX editing
Fulvid is an open-source desktop editor for people who keep Markdown and MDX documents on disk. It opens individual files or folders, edits the source in place, and saves back to the same path. The filesystem remains the source of truth: there is no account, cloud workspace, proprietary document format, or separate vault described by the project.
The app is designed for local, source-oriented workflows rather than document runtime features. Markdown and MDX can be previewed as readable, inert HTML, while MDX JSX remains text and is not executed. This makes Fulvid suited to notes, documentation trees, and MDX source that must remain usable by Git, other editors, or an external static-site toolchain.
Core capabilities
Markdown and MDX support
Work with .md, .markdown, and .mdx files in the same editor. MDX remains source text, including JSX, and is syntax-highlighted without being executed.
Folder navigation and search
Use local find, folder-wide Global Search, and Quick Open to locate documents by title, filename, or path. Explorer and the other folder views are optional.
Source-adjacent preview and HTML export
View the active buffer beside the editor as inert HTML, then export that representation to a .html file. The preview does not run MDX or fetch network content.
Document navigation and context
Follow links in Markdown or Wikilink mode, inspect heading outlines and document context, and view a graph of links resolved within the open folder.
Bounded local extensions
Install local extensions for bounded actions such as menu commands, note templates, and selection transforms. Extension packs are ordinary files and do not receive filesystem, network, or live-editor access.
Practical uses
Local notes and personal writing
Edit a folder of Markdown notes without importing them into a proprietary library or changing their location and format. Files remain available to Git and other editors.
Documentation repositories
Work through documentation trees that contain both Markdown and MDX. Folder search, Quick Open, outlines, link resolution, and the graph help navigate the existing files.
MDX source maintenance
Inspect and revise MDX source while keeping JSX visible as text. Use the editor for source changes, then rely on an external static-site or component toolchain for execution and rendering.
Portable drafting and handoff
Draft a file in an untitled tab, save it later, and use Preview or HTML export when a readable representation is needed without modifying the source format.
Pros and Cons
Pros
- Keeps Markdown and MDX as ordinary files at their existing paths.
- Supports Linux, Windows, and macOS as a standalone local desktop application.
- Combines source editing with folder search, link navigation, outline, context, graph, preview, and HTML export.
- Local extensions are deliberately bounded and do not receive filesystem, network, or live-editor access.
Cons
- MDX components are not compiled or executed, so rendered component previews require an external toolchain.
- Preview is intentionally limited: embedded HTML is escaped, images are placeholders, and it does not fetch network content.
- The product-specific documentation does not establish pricing or hosted collaboration features.
FAQ
What platforms does Fulvid support?
Fulvid is a standalone desktop application for Linux, Windows, and macOS. It runs locally and works with files on the computer rather than a cloud workspace.
How do I use Fulvid with my documents?
Open a Markdown or MDX file through the native file dialog, or open a folder for Explorer, Quick Open, Global Search, Graph, and Document Context. You can also work with untitled tabs before choosing a save location.
Which file formats does Fulvid support?
Fulvid opens and edits Markdown files with .md or .markdown extensions and MDX files with the .mdx extension. Existing Markdown files remain Markdown, while new documents default to MDX.
Does Fulvid render or execute MDX components?
No. Fulvid treats MDX as source code: it can syntax-highlight JSX, but it does not execute JSX, load components, compile MDX, or turn Preview into a React runtime.
What does Fulvid Preview do?
Preview displays the active buffer as inert HTML. Embedded HTML is escaped, MDX is not executed, images are shown as placeholders, and the preview does not fetch from the network. Export HTML writes the same representation to a .html file.
