EdgeEver is a modern, open-source notes and knowledge base workspace. It revives the beloved Evernote-style three-pane layout 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 long-time Evernote users simply want a reliable, open, and fast personal knowledge base. However, existing mainstream solutions all present tradeoffs:
- Evernote: It has grown increasingly bloated with commercial ads and unnecessary features, degrading performance. Data export is cumbersome, free tiers are heavily restricted, and AI/MCP features require costly subscriptions.
- 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.
- 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, including sync and self-hosting. 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.
💡 Recommended Workflow:
Capture inspiration seamlessly across all devices and organize deeply in the classic three-pane view. Powered by native MCP and ACP, external agents can retrieve and organize your notes seamlessly, while the desktop app lets you collaborate deeply with local AI agents on your machine. Publish anywhere with one-click formatting—100% self-hosted at zero cost, building an open and truly owned second brain.

- Everywhere You Need It: Available on the Web, Android, macOS, Windows, Linux, and iOS; the Web Clipper supports Chrome, Edge, and Firefox.
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, create a Worker named `edgeever` from the Fork's `main` branch.
Use the repository root, keep Cloudflare's default Workers Builds deploy command,
and ensure its API token can read and edit D1. Select Save and Deploy.
4. After the Worker is created, add the user's chosen password as the runtime Secret
`EDGE_EVER_AUTH_PASSWORD` (preferably at least 32 characters).
The username defaults to `admin`.
If the user specifies another, set `EDGE_EVER_AUTH_USERNAME` as a Workers Builds
variable before the next build.
5. Run the build again, verify `/api/health` and `/api/openapi.json`, then log in
with that administrator username and password.
6. Enable and manually run the GitHub Actions workflow named `Update deployed EdgeEver`
once so the Fork can automatically receive future stable releases and fixes.
Detailed requirements: AI Agent Cloudflare Deployment.
Option B: Manual Online Deployment
Complete setup in 6 web steps:
- Fork the Repository: Click Fork at the top right of GitHub to fork EdgeEver into your personal account.
- Create Cloudflare Resources: Create D1
edgeever and R2 edgeever-resources.
- Import & Configure the Project: Create a Worker named
edgeever from the Fork's main branch in Cloudflare Workers & Pages. Use the repository root and keep Cloudflare's default Workers Builds deploy command, which runs in Cloudflare. Ensure its API token can read and edit D1. The deploy command creates the bindings; do not edit Fork files.
- Choose the Administrator Password: Choose an administrator password, preferably at least 32 characters. Once the Worker is created, save it as the runtime Secret
EDGE_EVER_AUTH_PASSWORD.
- Build & Verify: Save and Deploy creates the Worker and starts a build. If it fails because the administrator Secret is missing, add the runtime Secret from step 4 and retry. The username defaults to
admin; to use another, set the EDGE_EVER_AUTH_USERNAME Workers Builds variable before retrying. Once deployed, confirm /api/health returns 200, then log in with the configured username and password.
- Enable Automatic Updates: Open the Fork's Actions tab, click I understand my workflows, go ahead and enable them, then manually run Update deployed EdgeEver once so the Fork can automatically receive 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
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.
Multi-Account Login
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.
Browser Web Clipper
- Smart Article Extraction: Automatically extracts article content and converts it into clean Markdown, preserving the source URL and clipping timestamp.
- Selection & Context Menu Clipping: Save selected text or right-clicked images directly as notes without capturing the entire page.
- X (Twitter) Post Clipping: Right-click any post to automatically expand full text and archive the author, timestamp, and attached images together.
- Private Self-Hosted Direct Connection: Sends clipped content directly to your personal EdgeEver instance without third-party relays.
Community and Feedback
- Bugs, feature requests, and deployment issues: GitHub Issues
- Code contributions: read the Contribution Guide. If your Fork is also used to deploy EdgeEver, keep its

Content Formats
EdgeEver stores note content in three forms:
content_json TipTap/ProseMirror document, the editor source of truth
content_markdown API, Agent, import, and export format
content_text Search, summary, and indexing text
Open Profile -> Import and export to export or import an EdgeEver ZIP. Its notes/ directory is directly readable and portable as Markdown, while its structured data supports complete recovery between EdgeEver instances. Import preserves unrelated target data and overwrites records with matching EdgeEver IDs.
MCP
Create an API token in Profile -> MCP settings and give it to your AI Agent. The Agent can then securely manage your knowledge base within your account permissions. It supports both text notes and diagram notes (including mind maps, flowcharts, and architecture diagrams) with full CRUD capabilities. The Agent can create a structured table note from a field plan, edit its fields, and read, add, update, or delete its records. The Agent can also manage note templates and AI instructions.
💡 Inspiration:
Make AI your true knowledge orchestrator and creative co-pilot—instantly turn concepts into interactive mind maps and architecture diagrams, 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.
Image Compression
Image compression happens in the Web client before upload and is controlled by the Compress note images setting. When enabled, PNG, JPEG, WebP, and AVIF files are converted to WebP when beneficial, with the longest edge limited to 2560px. If compression does not reduce size, the original file is kept.
EdgeEver avoids Worker-side image processing to reduce compute and image-processing quota usage. REST API and MCP upload paths store the file content provided by the client without additional server-side compression.
Advanced 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.
Migration
If you want to migrate notes from other platforms to EdgeEver, please refer to the following simple migration guides:
Docker Deployment
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.
Sync Timing
Web, PWA, and desktop upload memo edits after 30 seconds of inactivity and check for remote changes every 5 minutes while visible; focus and manual refresh remain immediate. Adjust DEFERRED_MEMO_SYNC_DELAY_MS and BACKGROUND_WORKSPACE_REFRESH_INTERVAL_MS in apps/web/src/lib/workspace-refresh.ts.
