Dillinger
Dillinger is a free web-based Markdown editor for writing and previewing documents, with no signup requirement.
What Dillinger is
Dillinger is a free web-based Markdown editor for writing and previewing documents, with no signup requirement. Its Monaco editor includes syntax highlighting, multiple cursors, find and replace, and autocompletion. A side-by-side preview renders as you type and keeps its scrolling aligned with the editor. You can drag and drop files to import them, then export Markdown, styled HTML, or PDF. Dillinger can also import and save files through GitHub, Dropbox, Google Drive, OneDrive, and Bitbucket; GitHub support includes public and private repositories and saving edits back. After its initial load, the editor works offline and keeps drafts in local storage, while cloud sync requires connectivity. The editor offers dark mode, fullscreen Zen mode, and Vim and Emacs keybindings. Its site describes use by developers, technical writers, and AI builders for READMEs, documentation, blog posts, and LLM prompts. Documents save automatically in the browser, and Dillinger says they are not stored on its servers.

The full review of Dillinger
Dillinger is a free, browser-based Markdown editor aimed at developers, technical writers, and AI builders. It suits people who want a capable drafting workspace without an account, especially when files need to move between local storage and cloud repositories. Its strongest case is focused Markdown work with immediate rendered feedback; readers seeking a full note-taking system or a dedicated desktop app should look elsewhere.
Overview
Dillinger puts editing and rendered output side by side, updating the preview as you type and keeping scrolling aligned between panes. That arrangement makes document structure visible while you draft, reducing the need to switch modes when checking headings, lists, links, or other Markdown formatting.
The service requires no signup and automatically saves documents in the browser. Dillinger says documents are not stored on its servers, which makes the browser-local workflow attractive for drafts that should remain under the writer's control. After the first page load, the editor continues working offline and retains drafts in local storage. Offline work does not extend to cloud synchronization, so online services still require a connection before changes can be imported or saved.
Key features
Editor and preview
The Monaco-based editor provides syntax highlighting, multiple cursors, find and replace, and autocompletion. These are meaningful advantages for technical documentation, README files, and long drafts with repeated terminology or structural changes. They make Dillinger more capable than a plain browser text box, while the product remains deliberately centered on Markdown rather than a broad writing suite.
Live rendering and synchronized scrolling help catch formatting problems during composition instead of at the end. Dark mode and fullscreen Zen mode offer alternate visual environments, while Vim and Emacs keybindings accommodate writers who already rely on those editing conventions.
Files and integrations
Drag-and-drop import handles existing files, and documents can be exported as Markdown, styled HTML, or PDF. That range covers source-file handoff, browser-ready pages, and a shareable document format without requiring another conversion tool.
Dillinger connects with GitHub, Dropbox, Google Drive, OneDrive, and Bitbucket for importing and saving files. GitHub support includes Markdown files in both public and private repositories, with edits saved back to GitHub. These integrations make the editor a practical bridge for documentation stored across services, though they do not remove the need for connectivity when syncing.
AI-oriented writing
Dillinger positions its Markdown workflow for prompts, AI-generated content, technical documentation, and knowledge bases used with large language models. That focus is useful for builders who want clean, portable Markdown around AI projects, but it does not turn the editor into an AI generation or management platform.
Pricing
Dillinger has one plan:
| Plan | Price | What it includes |
|---|---|---|
| Free | free | No signup, no paywall, and no usage limits |
There is no free trial because the product is free outright. The absence of seats, quotas, or a subscription makes it suitable for solo writers, occasional contributors, and teams evaluating a browser Markdown workflow without procurement overhead. Users who need paid support, expanded collaboration controls, or an offline cloud replica will not find a higher tier to provide them.
Platforms
Dillinger runs on the web. The browser format makes it available across supported devices without installation, while offline drafting begins only after the initial load and keeps work in local storage.
Who it's for
Developers can edit and return README files through GitHub, technical writers can maintain documentation with a live structural check, and AI builders can keep prompts and knowledge-base material in portable Markdown. It also fits anyone who wants unlimited, no-account drafting and export to HTML or PDF.
It is a weaker fit for readers who prefer a native desktop application, need a broader note-taking environment, or depend on cloud access while disconnected. Local drafts remain usable offline, but synchronized copies cannot be updated until the network returns.
Pros and cons
Pros
- Unlimited free access: the 0.00 USD plan has no signup, paywall, or usage limit.
- Strong Markdown workflow: Monaco editing tools, aligned live preview, and keyboard modes support technical and repetitive writing.
- Flexible file movement: drag-and-drop import plus Markdown, styled HTML, and PDF export cover common handoff needs.
- Broad storage connections: GitHub, Dropbox, Google Drive, OneDrive, and Bitbucket reduce manual downloading and uploading.
- Offline local drafts: writing can continue after the initial load without a network connection.
Cons
- Web-only: readers wanting a dedicated Linux, macOS, or Windows application need another editor.
- Sync depends on connectivity: offline local storage cannot update cloud repositories until the connection is restored.
- Focused scope: it is a Markdown editor, not a full note-taking or general writing suite.
Alternatives
StackEdit is the closest free web alternative for readers who also value open-source software and no stated usage limits.
HackMD is the better choice when collaboration matters and a free workspace for up to three teammates is sufficient, though its free plan has stated limits such as GitHub pushes, invitees, templates, and image size.
MarkText, Ghostwriter, and Zettlr are preferable when you want free, open-source desktop software for Linux, macOS, or Windows.
HedgeDoc fits readers seeking a self-hosted or web deployment under the AGPL 3.0 license.
Markra is an option for users who want cross-platform access and are comfortable configuring a provider for its AI features.
Muesli suits readers looking for a free, open-source service spanning web, desktop, API, and self-hosted deployments.

Verdict
Choose Dillinger if you want an unrestricted, no-account Markdown editor with a genuinely useful live preview, practical cloud connectors, and offline local drafting. Its focused browser design is the main reason to choose it; the same web-only, Markdown-first scope is the main reason to look elsewhere for a native app, richer notes, or collaboration beyond file synchronization.
