edgeever

EdgeEver is a modern, open-source notes and knowledge base workspace. It preserves the classic, high-efficiency three-pane productivity workflow (Tree View · Note List · Editor) while offering an open data architecture and seamless AI Agent integration for complete ownership and smart productivity.

💡 Serverless & 100% Free Forever EdgeEver can run within Cloudflare's free quotas with no server purchase or VPS maintenance. Users who prefer a VPS, NAS, or home server can deploy the same application with Docker.

⭐ If EdgeEver is useful to you, consider giving it a Star. Your support helps more people discover the project.

Why EdgeEver

Many users of note-taking apps and personal knowledge bases simply want a reliable, open, and fast personal knowledge base. However, existing mainstream solutions all present tradeoffs:

• Evernote: Offers the smoothest, most seamless multi-device cloud sync experience. Yet as it evolved into a full-featured commercial suite, ads and add-ons multiplied while system overhead climbed. Meanwhile, free-tier quotas tightened, premium AI subscriptions grew expensive, and it remains difficult to integrate into modern self-hosted and private AI workflows.
• Obsidian: Open files, closed-source core. Official Sync is paid and third-party sync is tedious; relying entirely on flat local file scanning causes noticeable cold-start and search lag once notes reach thousands or heavy plugins are loaded; storing images and attachments alongside notes quickly bloats vaults, making mobile sync sluggish and leaving orphaned files behind; and it is overly heavy for lightweight, capture-anywhere use.
• Joplin: A veteran open-source three-pane note app, yet its UI design and editing experience feel stuck more than a decade in the past, lacking modern polish and fluidity. Fast official sync (Joplin Cloud) requires a paid subscription; free sync via WebDAV or cloud drives relies on file-by-file polling that becomes sluggish on mobile as notes and attachments grow, while self-hosting Joplin Server requires maintaining your own server with no zero-cost serverless option. It also lacks a full browser-based web workspace and native AI Agent capabilities (MCP/ACP).
• Memos & Stream Notes: Clean and simple, but their social-timeline layouts differ fundamentally from the structured productivity of a classic three-pane workflow.
• SiYuan & Block-based PKMs: Powerful with self-hosting support, but their granular "block-level" architecture imposes noticeable cognitive overhead for quick daily capture and continuous prose writing. Furthermore, they lack a true zero-cost serverless deployment tier, and multi-device sync relies on paid official subscriptions or paying extra to unlock S3/WebDAV sync features with your own storage.

EdgeEver fills this gap: The entire stack is open source, delivering truly seamless, low-latency, instant multi-device cloud sync with full self-hosting freedom. It keeps the three-pane layout you know, stays silky-smooth and lightweight even with 10,000+ notes, and ships native AI agents with zero-cost deployment.

Deployment

Cloudflare is the recommended zero-server deployment. Docker is available for users who prefer a VPS, NAS, or home server.

For Cloudflare, choose either of the following online deployment options:

Option A: Deploy with an AI Agent (Recommended)

Copy the prompt below directly into an AI Agent (such as Codex, Claude, Cursor, WorkBuddy, Antigravity, OpenClaw, Hermes Agent, etc.). During execution, if access to GitHub or Cloudflare is required, review the requested permissions and follow the prompts to authorize access.

Deploy EdgeEver entirely through GitHub and Cloudflare:
1. Fork https://github.com/tianma-if/edgeever.
2. Create D1 `edgeever` and R2 `edgeever-resources` in Cloudflare.
3. In Workers & Pages, select "Start with Hello World!" and create a Worker named `edgeever`.
4. Add the user's chosen password as the runtime Secret `EDGE_EVER_AUTH_PASSWORD`
   under Settings → Variables and Secrets, and deploy the Secret (preferably at least
   32 characters). The username defaults to `admin`.
5. Only after the Secret is deployed, open this Worker's Settings → Builds → Connect
   and connect the Fork's `main` branch.
6. In this Worker's Settings → Builds → API token, select or create the Cloudflare API token used for deployment, with D1 read/edit permission for the target account.
7. In the Fork's GitHub repository, open Actions → Update deployed EdgeEver, enable the workflow if prompted, and select Run workflow on `main`. After confirming in Cloudflare that the corresponding build succeeded and deployment completed, verify `/api/health` and `/api/openapi.json`, then log in with the administrator
   username and password.
   This workflow will automatically sync future stable releases and fixes.

Detailed requirements: AI Agent Cloudflare Deployment.

Option B: Manual Online Deployment

Complete the following 7 web steps strictly in order:

1. Fork the Repository: Click Fork at the top right of GitHub to fork EdgeEver into your personal account.
2. Create Cloudflare Resources: Create D1 edgeever and R2 edgeever-resources.
3. Create the Worker: In Cloudflare Workers & Pages, select Create application → Start with Hello World!, name the Worker edgeever, and deploy it. This creates a placeholder; EdgeEver is deployed in Step 7.
4. Set the Administrator Password: Under the Worker’s Settings → Variables and Secrets, add EDGE_EVER_AUTH_PASSWORD as type Secret and click Deploy. Its value is your chosen login password, preferably at least 32 characters. Complete this before connecting the Fork.
5. Connect the Fork: In the existing Worker’s Settings → Builds → Connect, select the Fork and production branch main.
6. Configure Deployment Permissions: In this Worker's Settings → Builds → API token, select or create the Cloudflare API token used for deployment, with D1 read/edit permission for the target account.
7. Build & Verify: In the Fork's GitHub repository, open Actions → Update deployed EdgeEver, enable the workflow if prompted, and select Run workflow on main. After confirming in Cloudflare that the corresponding build succeeded and deployment completed, confirm /api/health returns 200 and verify login. This workflow will automatically sync future stable releases and fixes.

📖 For full step-by-step instructions and configuration details, see the Online Deployment Guide.

Custom Domain & Access: After deployment, you can directly use the default *.workers.dev domain assigned by Cloudflare, or attach your own custom domain in the Worker settings under Settings → Domains & Routes.

Cloudflare R2 Activation: Although Cloudflare R2 offers a generous free storage allowance that note-taking workloads remain completely within, you must first activate an R2 subscription and add a payment method. Cloudflare officially supports UnionPay, Visa, Mastercard, and other cards, as well as PayPal, Apple Pay, Google Pay, and other payment methods.

Option C: Docker on a VPS or NAS

Docker runs the same frontend, API routes, services, authentication, MCP implementation, and migrations as Cloudflare. The container uses SQLite with local files or S3-compatible attachment storage and supports amd64 and arm64. See Deploy EdgeEver with Docker and Self-hosting and Docker architecture.

Use the GitHub-hosted installer and the official GHCR image:

curl -fsSL https://edgeever.org/install.sh | bash

The command pulls the latest image, generates an administrator password, and starts EdgeEver with Docker Compose.

See the Docker deployment guide for manual deployment and configuration.

After installation, updates run automatically each day by default. To update manually, run ~/edgeever/update.sh on the deployment server.

Advanced Configuration & Management

Data Backup, Export & Migration

Whether for routine data backups, seamless cross-instance migration, or switching from existing note platforms, EdgeEver provides reliable, complete data mobility:

• EdgeEver Native Backup & Restore: In the app, go to Profile -> Import and export to export or import an EdgeEver ZIP archive at any time. The extracted notes/ directory keeps clean plaintext Markdown files and attachments for local archival or direct reading, while internal structured metadata enables lossless full restoration across different EdgeEver instances. Importing preserves existing unrelated data on the target instance and automatically overwrites records with matching IDs.
• Smooth Migration from Third-Party Apps: Whether importing via the native one-click GUI (supporting complete notes, hierarchies, and attachments from Evernote, Obsidian, and Joplin) or migrating from Notion, flomo, Memos, and other platforms via AI Agent & MCP, EdgeEver provides seamless, verified data mobility. See the Third-Party Notes Migration Guide.

AI & MCP Protocol Integration

Create an API token in Profile -> API / MCP and copy the Remote MCP configuration in one click to let AI Agents such as Claude Code, Cursor, Antigravity, and OpenClaw securely manage your knowledge base within account permissions. EdgeEver supports full CRUD for text notes, visual diagram notes (mind maps, flowcharts, and architecture diagrams), structured table notes, and native poster notes. Agents can also manage notebook hierarchies, tags, attachments, revision history, note templates, and AI instructions.

For client setup, token access levels, troubleshooting and suggested rules for agents, see Using EdgeEver with MCP clients.

💡 Inspiration: Make AI your true knowledge orchestrator and creative co-pilot—instantly turn concepts into interactive mind maps, flowcharts, architecture diagrams, and structured tables, while supplying private context to your AI Agents. Paired with EdgeEver’s powerful rich-text editing and elegant typography, AI-assisted content becomes beautifully structured, polished, and publication-ready knowledge assets.

Multi-Account Login & Storage Management

Once deployed, a single instance supports multi-account login.

The instance administrator can create, disable, or reset member accounts in Profile -> User accounts. Each member gets a fully isolated personal workspace, including notebooks, notes, attachments, Trash, import/export, and MCP tokens. An intuitive storage usage dashboard provides real-time visibility into attachment storage consumed across the whole instance as well as per account.

Storage Extension & Third-Party Image Hosting

• OSS Object Storage: The instance owner can configure S3-compatible object storage under Settings → Advanced → OSS object storage. Changing storage does not migrate or affect existing attachments.
• Desktop PicGo integration: The desktop app can hand inserted images to a PicGo or PicList server on this computer or on another machine you trust, such as a NAS. That server uploads them to GitHub, SM.MS, Upyun, Qiniu, or a custom image host. The address only needs to end with /upload, so a PicList behind a reverse proxy works too.
• Desktop CloudFlare ImgBed: The desktop app can also upload inserted images straight to your self-hosted CloudFlare ImgBed with an API token. The upload folder accepts PicList-style placeholders such as {Y}/{m}/{d} and {memoId}.

Plugins and Themes

Web and desktop apps support functional plugins and custom themes, installable from the official marketplace, GitHub, or a Manifest URL, with seamless sync across your workspace. Developers can extend capabilities using @edgeever/plugin-api; see the plugin development guide and marketplace submission policy.

Data Storage Model

EdgeEver persists note content simultaneously across three formats to balance editing performance, open portability, and full-text search speed:

content_json      TipTap/ProseMirror document, the editor source of truth
content_markdown  API, Agent, export, and external ecosystem interoperability
content_text      Full-text search, summary generation, and indexing

Core Mechanisms & Design Decisions

• Client-Side Silent Compression: To avoid consuming compute quota on serverless runtimes like Cloudflare Workers, image compression occurs in the Web client before upload (converting PNG/JPEG/WebP/AVIF to WebP when beneficial, max edge 2560px; original retained if compression does not reduce size). REST API and MCP endpoints store client-supplied binaries directly without additional server-side transcoding.
• Offline-First & Sync Timing: Web, PWA, and desktop clients automatically upload memo edits after 30 seconds of typing inactivity, and poll for remote changes every 5 minutes while visible; window refocus and manual refresh remain immediate. Configurable via DEFERRED_MEMO_SYNC_DELAY_MS and BACKGROUND_WORKSPACE_REFRESH_INTERVAL_MS in apps/web/src/lib/workspace-refresh.ts.

Contributing Code

Community contributions are warmly welcome! Please keep the following guidelines in mind:

• Please review the Contribution Guide before submitting code.
• Deployment Isolation: If your GitHub Fork is also used to deploy EdgeEver, keep its main branch clean and deployment-only. Create a dedicated branch from official upstream/main for features/fixes and pull requests; do not develop on or run Sync fork directly on the deployment main.
