The tool, available at markups.dev with source on GitHub, offers a split live-preview workflow along with Mermaid diagrams, KaTeX equations, code blocks, linting, templates, and export to .md, HTML, and PDF, built on Microsoft's Monaco Editor. The project emphasizes a local-first, frictionless approach to editing Markdown files.", "body_md": "Markdown is one of those formats developers end up using almost everywhere.\n\nREADME files. Documentation. Architecture notes. API docs. Project specifications. AI-generated content. Blog drafts. Changelogs. Notes written during debugging sessions.\n\nThe format itself is simple.\n\nThe workflow around it isn't always.\n\nSometimes you just want to open a Markdown editor, write something, see the rendered result, and export it.\n\nInstead, many tools push you toward an account, a cloud workspace, or a larger platform before you can even start writing.\n\nThat was the problem I was trying to solve when I built **Markups**.\n\n**Open it. Write Markdown. See the result. Keep control of your document.**\n\n**Live:** [markups.dev](https://markups.dev/)\n\n**Source:** [github.com/Nir-Bhay/markups](https://github.com/Nir-Bhay/markups)\n\n**Markups is an open-source, browser-based Markdown editor designed to make Markdown work feel simple again.**\n\nYou can open [markups.dev](https://markups.dev/) and start writing without downloading a desktop application or creating an account. The editor provides a split Markdown and live-preview workflow, along with features that become useful when a document stops being \"just text\" — diagrams, equations, code blocks, navigation, linting, templates, and export options.\n\nThe current project combines a developer-oriented editor experience with a local-first approach to document handling.\n\n```\n                 ┌──────────────────────┐\n                 │      Markdown        │\n                 │   file / document    │\n                 └──────────┬───────────┘\n                            │\n                            ▼\n                 ┌──────────────────────┐\n                 │       Markups         │\n                 │  Edit + Preview      │\n                 └───────┬─────┬────────┘\n                         │     │\n              ┌──────────┘     └──────────┐\n              ▼                           ▼\n       ┌─────────────┐             ┌─────────────┐\n       │   Preview   │             │   Tools     │\n       │   Render    │             │ Mermaid     │\n       └──────┬──────┘             │ KaTeX       │\n              │                    │ Code blocks │\n              │                    └──────┬──────┘\n              ▼                           │\n       ┌──────────────────────────────────┘\n       │\n       ▼\n ┌────────┬────────┬─────────┐\n │  .md   │  HTML  │   PDF   │\n └────────┴────────┴─────────┘\n```\n\nThe goal isn't to replace every development tool you already use.\n\nIt's to make the **Markdown layer between those tools** easier to work with.\n\nThe more Markdown I worked with, the more obvious the friction became.\n\nA `.md` file is portable by design. You can open it in an editor, commit it to Git, send it to someone, put it in a repository, or publish it somewhere else.\n\nSo I kept asking myself:\n\n**Why should editing that file require a full cloud workflow?**\n\nI wanted a tool where the first step is simply:\n\n```\nOpen the editor\n      ↓\nStart writing\n      ↓\nPreview the document\n      ↓\nExport / save\n```\n\nNo onboarding flow.\n\nNo mandatory workspace setup.\n\nNo need to turn a simple Markdown file into a hosted account just to edit it.\n\nThat became one of the design principles behind Markups.\n\nOne of the most important decisions in Markups is also one of the easiest to explain:\n\n**You don't need to create an account just to edit Markdown.**\n\nOpen [markups.dev](https://markups.dev/), and the editor is there.\n\nThat changes the interaction from:\n\n```\nOpen editor\n   ↓\nCreate account\n   ↓\nVerify / sign in\n   ↓\nCreate workspace\n   ↓\nCreate document\n   ↓\nStart writing\n```\n\ninto:\n\n```\nOpen markups.dev\n      ↓\nStart writing\n```\n\nFor a lot of small documentation tasks, that's exactly what I want from a tool.\n\nUnder the hood, Markups uses **Microsoft's Monaco Editor**, the same editor technology used by VS Code. That gives the editing surface a much more familiar developer feel than a basic browser text box.\n\nThe editor supports things like:\n\nIf you already spend your day in an IDE, the editor doesn't feel completely foreign when you move over to Markdown.\n\nWriting Markdown and reading rendered Markdown are two different activities.\n\nYou need both.\n\nMarkups provides a live preview so you can edit the source and immediately see how the document is going to look.\n\n```\n┌─────────────────────────┬─────────────────────────┐\n│     Markdown Source     │     Rendered Preview    │\n│                         │                         │\n│ # API Documentation     │ API Documentation      │\n│                         │ =================      │\n│ ## Authentication       │ Authentication         │\n│                         │                         │\n│ - Bearer token          │ • Bearer token         │\n│ - Expiration            │ • Expiration           │\n│                         │                         │\n└─────────────────────────┴─────────────────────────┘\n```\n\nThe current editor supports split view as well as a single-pane workflow, synchronized scrolling, and a document mode for a more rendered-document-oriented editing experience.\n\nA Markdown editor becomes much more useful when it can handle the things developers actually put into their documents.\n\nMarkups supports common GitHub-flavored Markdown patterns such as:\n\nIt also extends the document with:\n\n**KaTeX for math**\n\n``` bash\n$$\nE = mc^2\n$$\n```\n\n**Mermaid for diagrams**\n\n``` php\nflowchart TD\n    A[Developer] --> B[Markdown]\n    B --> C[Markups]\n    C --> D[Live Preview]\n    C --> E[Export]\n    D --> F[Review]\n```\n\n**Syntax-highlighted code blocks**\n\n``` js\nasync function getUsers() {\n  const response = await fetch(\"/api/users\");\n  return response.json();\n}\n```\n\nThis matters because modern technical documents are rarely just paragraphs.\n\nThey contain code, architecture diagrams, tables, equations, checklists, examples, and structured notes.\n\nOne thing I like about Markdown-based diagrams is that the diagram can live **with the documentation**.\n\nFor example:\n\n``` php\nflowchart LR\n    Client --> API\n    API --> Auth\n    Auth --> Service\n    Service --> Database\n```\n\nInstead of maintaining a paragraph explaining the architecture and then keeping a completely separate image somewhere else, the diagram can be part of the document's source.\n\nChange the architecture?\n\nChange the Markdown.\n\nThat is a very natural workflow for developers.\n\nThere are documents where plain Markdown isn't enough.\n\nResearch notes, educational content, engineering documentation, data explanations, and technical articles can all need equations.\n\nWith KaTeX support, you can write mathematical expressions directly in the document:\n\n```\n$$\n\\frac{d}{dx}x^n = nx^{n-1}\n$$\n```\n\nThe point isn't to turn Markups into a mathematics product.\n\nIt's simply to avoid having technical content break when the document needs one more layer of structure.\n\nAnother practical part of the workflow is export.\n\nFrom the same document, Markups can produce:\n\n```\n                  ┌─────────────┐\n                  │   Markups   │\n                  └──────┬──────┘\n                         │\n           ┌─────────────┼─────────────┐\n           ▼             ▼             ▼\n        Markdown        HTML          PDF\n           │             │             │\n           ▼             ▼             ▼\n        .md file     Web-ready     Shareable\n                      document      document\n```\n\nThe current project supports downloading Markdown, exporting to HTML, and exporting to PDF. Existing Markdown files can also be imported so you can continue working on a document you already have.\n\nThat makes the workflow useful when Markdown is the **source of truth**, but the final output needs to be something else.\n\nMarkups isn't limited to editing and previewing.\n\nThe current project also includes features aimed at longer or more repetitive documents:\n\n| Feature | Why it is useful | \n|---|---|\n| Multi-tab documents | Work on more than one document without constantly replacing the current file | \n| Templates | Start common document types faster | \n| Text snippets | Reuse Markdown boilerplate | \n| Focus mode | Remove distractions while writing | \n| Typewriter mode | Keep the active writing position visually centered | \n| Word / character count | Useful for articles and documentation with size constraints | \n| Reading time | Quick estimate for longer documents | \n| Table of contents | Navigate large documents quickly | \n| Markdown linter | Catch formatting and style issues while writing | \n\nThese are small things individually.\n\nTogether, they make Markdown feel more like a real writing environment instead of a box where you paste syntax.\n\nThis is where I think the project gets more interesting.\n\nYou don't have to use Markups for everything.\n\nIt works well as a layer around workflows you already have.\n\nYou can draft or clean up a README in Markups, review the rendered result, then save the Markdown file back into your repository.\n\n```\nRepository\n   │\n   └── README.md\n          │\n          ▼\n       Markups\n          │\n     ┌────┴────┐\n     ▼         ▼\n  Edit      Preview\n     │         │\n     └────┬────┘\n          ▼\n      Save .md\n          │\n          ▼\n       Git commit\n```\n\nAPI docs, installation guides, contributor docs, deployment notes, internal specifications, and architecture documents are all natural Markdown use cases.\n\nMermaid makes it easy to keep architecture diagrams close to the documentation itself.\n\nThis is becoming a particularly interesting workflow.\n\nAI coding assistants can generate:\n\nBut generated Markdown often still needs human review.\n\nMarkups can be used as that review layer:\n\n```\nAI assistant\n     ↓\nGenerated Markdown\n     ↓\n   Markups\n     ↓\nReview + edit + preview\n     ↓\nFinal Markdown\n     ↓\nGit / Docs / Publish\n```\n\nThe idea is simple: let AI produce a first draft, then use a human-friendly editor to make it actually yours.\n\nMarkdown is also a natural format for writing developer articles.\n\nWith live preview, a table of contents, word count, reading-time information, and export options, Markups can work as a focused writing environment before content is published elsewhere.\n\nBecause the application is built as a Progressive Web App and uses browser caching, the project is designed to continue working after the initial application load. The repository includes a PWA manifest and service worker for this behavior.\n\nThat means a weak connection does not have to be the thing that stops you from writing.\n\nA big part of Markups is not a flashy feature.\n\nIt is the architecture choice behind the workflow.\n\nThe project is designed around **browser-based, local-first document handling** rather than making a hosted account the center of the product.\n\nA simplified view looks like this:\n\n``` php\nflowchart TD\n    U[Developer] --> B[Browser]\n    B --> E[Markups Editor]\n\n    E --> R[Markdown Renderer]\n    E --> S[(Browser Storage)]\n    E --> P[Live Preview]\n\n    R --> P\n\n    E --> M[Mermaid]\n    E --> K[KaTeX]\n    E --> H[Syntax Highlighting]\n\n    E --> X[Export]\n    X --> MD[.md]\n    X --> HTML[HTML]\n    X --> PDF[PDF]\n```\n\nThe important part is the direction of the workflow:\n\n**you start with the document, not with an account.**\n\nI wanted Markups to be useful for documents that people may not want to put into a hosted workspace simply to edit them.\n\nThe current project is built around client-side document handling and does not require an account for the core editing workflow. The project also uses browser storage for local persistence and export/save operations happen from the browser.\n\nThat gives the workflow a different feel from cloud-first editors:\n\n```\nYour document\n     │\n     ▼\n   Browser\n     │\n     ▼\n   Markups\n     │\n     ├── Edit\n     ├── Preview\n     ├── Persist locally\n     └── Export\n```\n\nThere is no mandatory hosted workspace sitting between you and the first edit.\n\nFor developers, that can be useful when working on unfinished ideas, private documentation, internal notes, or project material that simply doesn't need to live in another service.\n\n**The goal is not \"your files are magically private because the app says so.\" The goal is to keep the architecture simple enough that the user remains close to the document.**\n\nMarkups is implemented as a Progressive Web App.\n\nThe project includes a web app manifest and service worker so the application can cache the resources required to run after the initial load.\n\nIn practical terms, the intended workflow is:\n\n```\nFirst visit\n    ↓\nApplication loads\n    ↓\nBrowser caches app resources\n    ↓\nYou can install/bookmark it\n    ↓\nConnection disappears\n    ↓\nThe app can continue working from its cached resources\n```\n\nThis is particularly useful for the kind of editor that does not need a server round-trip just to render Markdown.\n\nOne important distinction: **offline application availability is not the same thing as cloud synchronization.**\n\nMarkups is not trying to become a cloud document collaboration platform. The project is deliberately much more focused than that.\n\nThere are plenty of excellent Markdown editors already.\n\nTools such as StackEdit and HackMD are useful for different workflows, especially when cloud synchronization and collaboration are part of the requirement.\n\nMarkups takes a different position.\n\n| Workflow need | Markups approach | \n|---|---|\n| Start editing immediately | No mandatory account for the core editor workflow | \n| Markdown source | First-class editing surface | \n| Live rendered output | Yes | \n| Mermaid diagrams | Built in | \n| Math | KaTeX support | \n| Code blocks | Syntax highlighting | \n| Local/browser workflow | Core design direction | \n| Offline-oriented use | PWA + browser caching | \n| Export | Markdown, HTML, PDF | \n| Open source | Yes | \n| Cloud collaboration | Not the primary goal | \n\nThe comparison isn't about declaring one product universally better than another.\n\nIt is about choosing the right workflow.\n\nIf you need a collaborative cloud workspace, use a tool designed for that.\n\nIf you want a focused Markdown editor that you can open and start using, Markups is built around that experience.\n\nImagine you're building an API and want to document it.\n\nYou might start with:\n\n```\n# User API\n\n## GET /users\n\nReturns a list of users.\n\n## Authentication\n\nUse a bearer token.\n```\n\nhttp\n\nAuthorization: Bearer \n\n```\n## Architecture\n```\n\nmermaid\n\nflowchart LR\n\n    Client --> API\n\n    API --> Auth\n\n    Auth --> UsersService\n\n    UsersService --> Database\n\nplaintext\n\nThen you can immediately see:\n\nAnd when you're done, you can keep the `.md` source or export the document to HTML/PDF.\n\nThat's the workflow I care about most.\n\nNot \"write Markdown because Markdown is cool.\"\n\n**Write Markdown because it is useful — and make the editor around it useful too.**\n\nYou don't need a complicated setup.\n\nGo to:\n\nOpen the editor and begin with Markdown on the source side.\n\nUse the live preview to check the rendered document while you write.\n\nAlready have a `.md` file? Import it and continue from there.\n\nTry:\n\nSave the Markdown source or export the document as HTML/PDF.\n\n| Shortcut | Action | \n|---|---|\n| `Ctrl + S` | Save Markdown | \n| `Ctrl + P` | Export / print to PDF | \n| `Ctrl + O` | Import Markdown | \n\nAnother important part of Markups is that it is open source and released under the MIT license.\n\nThat matters to me because a developer tool should be inspectable.\n\nYou can read the code.\n\nYou can understand how the application works.\n\nYou can contribute.\n\nYou can fork it.\n\nYou can adapt it for your own workflow.\n\nRepository:\n\n👉 [https://github.com/Nir-Bhay/markups](https://github.com/Nir-Bhay/markups)\n\nMarkups is a **focused Markdown workspace**.\n\nIt is not trying to replace:\n\nInstead, it sits in a much smaller space:\n\n```\nWrite\n  ↓\nPreview\n  ↓\nImprove\n  ↓\nExport / Save\n```\n\nThat simplicity is intentional.\n\nThere are still plenty of areas where a Markdown editor can get better.\n\nSome ideas I'm exploring include:\n\nThese are ideas, not promises about the current release.\n\nOne of the nice things about keeping the project open source is that the roadmap doesn't have to come entirely from one person.\n\nThe interesting part of Markups isn't really Markdown syntax.\n\nMarkdown already works.\n\nThe interesting part is the workflow around it.\n\nDoes writing a README need an account?\n\nDoes editing a `.md` file need a cloud workspace?\n\nDoes documentation always need to live inside another platform?\n\nI don't think it has to.\n\nSometimes a tool should simply:\n\n```\nOpen\n ↓\nWrite\n ↓\nPreview\n ↓\nExport\n ↓\nDone.\n```\n\nThat's the idea behind Markups.\n\nA free, open-source Markdown editor that you can open in your browser and start using without a mandatory account.\n\nIf that matches the way you work, give it a try.\n\n**Live App:** [https://markups.dev/](https://markups.dev/)\n\n**GitHub:** [https://github.com/Nir-Bhay/markups](https://github.com/Nir-Bhay/markups)\n\nAnd because the project is open source, feedback, issues, and contributions are always welcome.\n\nBuilt for people who just want to work with Markdown.", "url": "https://wpnews.pro/news/i-built-markups-a-free-open-source-markdown-editor-that-doesn-t-need-an-account", "canonical_source": "https://dev.to/nirbhay_hiwse/i-built-markups-a-free-open-source-markdown-editor-that-doesnt-need-an-account-5bb6", "published_at": "2026-09-13 06:47:12+00:00", "updated_at": "2026-09-13 06:56:19.763973+00:00", "lang": "en", "topics": ["developer-tools", "ai-tools"], "entities": ["Markups", "Microsoft", "Monaco Editor", "VS Code", "GitHub", "markups.dev"], "alternates": {"html": "https://wpnews.pro/news/i-built-markups-a-free-open-source-markdown-editor-that-doesn-t-need-an-account", "markdown": "https://wpnews.pro/news/i-built-markups-a-free-open-source-markdown-editor-that-doesn-t-need-an-account.md", "text": "https://wpnews.pro/news/i-built-markups-a-free-open-source-markdown-editor-that-doesn-t-need-an-account.txt", "jsonld": "https://wpnews.pro/news/i-built-markups-a-free-open-source-markdown-editor-that-doesn-t-need-an-account.jsonld"}}
