BlockNote

BlockNote is an open-source editor foundation for developers building rich-text features into web applications. It suits teams that want a ready-made block editor they can customize, with real-time collaboration and offline-storage options. Its main trade-offs are lossy conversions to standard HTML and Markdown, and a commercial license for closed-source use of XL features.

Overview

BlockNote is designed to power knowledge bases, note-taking apps, document editors, and internal tools—not to serve as a standalone writing app. Its animated interface and block-based document structure give developers a working editor experience without requiring them to assemble every interaction from scratch. Teams can also replace that interface or extend it with custom blocks and menus.

Key features

The editor is built on ProseMirror and TipTap, with structured content, table editing, and image, video, audio, and file blocks. File uploads are configurable, which gives applications control over how media is handled. React, Next.js, vanilla JavaScript, Mantine, Shadcn, and Ariakit support make it relevant across several web stacks.

Collaboration uses Yjs, with providers including Liveblocks, PartyKit, Y-Sweet, Hocuspocus, y-websocket, and y-webrtc. The range gives developers choices for connecting collaborative editing to their application architecture. The documentation also lists y-indexeddb for offline storage, useful when an editor needs to retain data locally.

BlockNote imports and exports its own JSON format and HTML. Conversions to standard HTML and Markdown are lossy, so applications that depend on portable, faithful round-tripping should treat that as a significant limitation. XL packages add AI integration, multi-column layouts, and exports to PDF, DOCX, ODT, and email; closed-source use of those packages requires a commercial license.

Pricing

Community: free. It includes all blocks and UI components, drag-and-drop editing, and real-time collaboration. XL packages are free for open-source software under GPL-3.0, making this the natural starting point for qualifying open-source projects. The pricing FAQ says there are no limits on documents or users, and both remain on the customer's own infrastructure.

Business: $195 a month, with $2,340 billed yearly; the page also shows “$390/mo now -50%”. It includes a commercial license for XL packages, one application per license, and standard support. This is the paid fit for closed-source applications that need XL features; the one-application term matters for teams deploying the editor in multiple products.

Enterprise: custom pricing, with custom licensing, dedicated support, feature development, and onboarding and integration guidance. It is aimed at organizations that need tailored licensing or closer implementation support. Priority Support includes a 48-hour first-response time and access through GitHub, email, and a dedicated Slack channel.

Platforms

BlockNote is available for web applications and self-hosted deployment. Its developer-oriented framework support and customer-owned document and user infrastructure suit teams that want to keep the editor within their own application environment.

Who it's for

BlockNote is strongest for developers who want a customizable block editor with collaboration but do not want to build the basic editing UI themselves. It is a good fit for web products with structured documents, media blocks, and a need to choose a Yjs provider. It is less suitable when standard Markdown or HTML must preserve content exactly, or when a closed-source product needs XL features without the Business license.

Pros and cons

• Pros: Ready-made animated UI, block structure, and drag-and-drop editing reduce the work of creating a bespoke editor foundation.
• Pros: Custom blocks, menus, or a fully custom UI give teams room to fit the editor to their product.
• Pros: Real-time collaboration and listed offline storage options support collaborative editing architectures.
• Pros: The Community plan has no document or user caps, with content and users on the customer's infrastructure.
• Cons: Standard HTML and Markdown conversions are lossy, limiting dependable interchange with those formats.
• Cons: Closed-source use of XL packages requires a paid commercial license, and Business covers one application per license.

Alternatives

Rich Text Editor Software is the broader category for comparing editors. Consider AiEditor if Android or iOS support is a priority. CKEditor 5 is another freemium option, with a free trial and a published Essential plan priced at $160 a month monthly, or $144 per month annual, for 5,000 editor loads per month before overage charges. Editor.js is a free option from the non-profit team CodeX.

Jodit offers a free MIT-licensed core editor with built-in plugins, plus custom-priced enterprise licensing. MDXEditor is a free web-based React component for authoring Markdown, with features enabled through plugins. Milkdown is a fully free, MIT-licensed open-source editor framework. Plate has a free plan with all plugins and a Personal plan for €299, paid once. ProseMirror is a free, commercially usable open-source library for teams that want to build on that foundation directly.

Verdict

Choose BlockNote if you are building a web application and want a customizable, collaborative block editor with a ready-made UI and no document or user caps. Its strongest case is the combination of a practical starting interface and developer control over structure and integrations. Look elsewhere if faithful standard-format conversion is essential, or if you need XL features in a closed-source product but cannot accept the Business license and its one-application term.
