💡 Serverless & 100% Free Forever EdgeEver uses a pure Serverless architecture. No server purchase or VPS rental is required, and there is no need to configure Docker or SSL certificates. By running within Cloudflare's free quotas, personal use is 100% free with zero maintenance.

⭐ 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: Exceptionally powerful and open, yet feels a bit heavy for quick, friction-free captures on the go. Official sync is subscription-based, while third-party sync setups demand significant effort.
• Memos & Stream Notes: Clean and simple, but their social-timeline layouts differ fundamentally from the structured productivity of a classic three-pane workflow.

EdgeEver fills this gap: It preserves the refined three-pane layout you know and love, while unlocking complete data ownership, native AI capabilities, and zero-cost self-hosted deployment.

💡 Recommended Workflow: Use EdgeEver as your central inbox to quickly capture ideas and notes on any device. When it's time to curate and publish, leverage MCP to let your AI assistant distill, tag, and sync them into Obsidian, Notion, or Feishu Bitable, or copy beautifully styled posts directly into Substack, Medium, or newsletters with a single click.

Deployment

EdgeEver uses a pure Serverless architecture that runs entirely within Cloudflare's free tiers. No VPS or server rental is required, and there is no need to configure Docker or SSL certificates.

You can deploy online using either of the following two options:

Option A: Deploy with an AI Agent (Recommended)

Copy this prompt into an AI Agent configured with GitHub and Cloudflare MCP servers, plugins, or other integrations (such as Codex, Claude, Cursor, Antigravity, OpenClaw, Hermes Agent, etc.):

Deploy EdgeEver online:
1. Fork https://github.com/tianma-if/edgeever.
2. Import the Fork into Cloudflare Workers & Pages.
3. Configure D1, R2, `EDGE_EVER_AUTH_USERNAME` (prefilled as `admin`, customizable), the `EDGE_EVER_AUTH_PASSWORD` Worker Secret, and the production `main` build.
4. Start the first build and verify `/api/health`, `/api/openapi.json`, and login.
5. Enable and run `Update deployed EdgeEver` once.

Detailed requirements: AI Agent Cloudflare Deployment.

Option B: Manual Online Deployment

Complete setup in 4 simple web steps:

1. Fork the Repository: Click Fork at the top right of GitHub to fork EdgeEver into your personal account.
2. Import into Cloudflare: Log into the Cloudflare Dashboard, navigate to Workers & Pages, and choose to import your Fork repository.
3. Bind Resources & Credentials: Bind the D1 database (DB), R2 bucket (RESOURCES), set EDGE_EVER_AUTH_USERNAME (default admin, customizable), and set the Worker Secret EDGE_EVER_AUTH_PASSWORD as your admin password.
4. Build & Verify: Start the first build with default settings. Once complete, visit /api/health to verify a 200 response before logging in.

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

💡 Deployment Tip (Cloudflare R2 Billing): Although Cloudflare R2 offers a generous free tier that note-taking workloads are unlikely to ever exceed, it requires binding a payment method (such as a dual-currency credit card) to activate. Based on personal experience, for users in mainland China, VISA cards from China Merchants Bank (CMB) or Shanghai Pudong Development Bank (SPDB) are typically the fastest to get verified (and most of these cards have no annual fees or easily waivable ones, so there are no extra holding costs).

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.

PWA Installation

EdgeEver can be installed as a PWA on desktop or mobile home screens. On desktop, open the site in Chrome or Edge and use the install icon in the address bar. On Android, open it in Chrome, use the three-dot menu, and choose Add to Home screen or Install. Avoid installing from embedded browsers such as WeChat.

Common pitfall: When installing the PWA on mobile, Chrome or Edge is recommended. Other mobile browsers may encounter compatibility issues or unexpected errors during installation.

Browser Web Clipper

The Chrome/Edge web clipper is officially published. You can install it directly from the link below (Microsoft Edge users can also install directly from the Chrome Web Store):

• Chrome Web Store Link

The same clipper code also supports Firefox. Until the Firefox Add-ons listing is published, see the extension development guide to build and temporarily load the Firefox package from source.

Native Clients

The Android app is now available on Google Play, with signed APKs also available from GitHub Releases. The iOS app has been submitted and is currently under App Store review.

The macOS app is available from GitHub Releases for both Apple Silicon and Intel Macs. The Windows version will be released once the code-signing certificate issue is resolved.

Tech Stack

• Bun workspace monorepo with Web, API, official site, and shared type package.

Quick Start

Install dependencies:

bun install

Apply local D1 migrations:

bun run db:migrate:local

Start the default development environment. It applies pending local migrations and initializes local D1/R2 stores once with the repository's fixed demo seed. Existing local changes are preserved on later restarts, and no remote instance is contacted.

bun run dev

To intentionally develop against a configured remote instance, select it explicitly:

EDGE_EVER_INSTANCE=<name> bun run dev:remote

Checks:

bun run typecheck
bun run build

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.

API

OpenAPI schema:

https://your-domain/api/openapi.json

Repository file: docs/openapi.json.

MCP

Create an API token in Profile -> MCP settings, then give the token or full MCP configuration to your AI Agent. Once connected, the Agent can securely read, organize, and import notes within your account permissions. Repeating the same import will not create duplicate notes.

With MCP, EdgeEver can also connect to tools such as Notion databases and Feishu Bitable, turning scattered ideas, information, and materials from everyday notes into structured data that is easier to organize, search, and manage.

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.

Migration

If you want to migrate notes from other platforms to EdgeEver, please refer to the following simple migration guides:

• Evernote Migration: Please refer to docs/evernote-migration-guide.md
• Memos Migration: Please refer to docs/memos-migration-guide.md
• Notion Migration: Please refer to docs/notion-migration-guide.md

Docker Deployment Roadmap

🐳 Docker-based self-hosting for VPS, NAS, and home servers is planned but is not yet a supported release. An experimental Bun runtime is already available for adapter development, with SQLite + local files or S3-compatible storage; PostgreSQL remains reserved at the contract level. See Self-hosting and Docker architecture.
