EdgeEver: An open-source, AI-native knowledge base & portable Evernote alternative.
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: 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
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 online:
1. Fork https://github.com/tianma-if/edgeever.
2. Create D1 `edgeever` and R2 `edgeever-resources` in Cloudflare.
3. Import the Fork into Cloudflare Workers & Pages and use `main` as the production
branch.
4. Add a Worker Secret named `EDGE_EVER_AUTH_PASSWORD`, using a password chosen by the
user as its value. Prefer a strong password of at least 32 characters that is unique
to this instance.
5. Start the first build, verify `/api/health` and `/api/openapi.json`, then verify login
with username `admin` and the configured password.
6. Enable and manually run the GitHub Actions workflow named `Update deployed EdgeEver`
once so the Fork can automatically receive the latest EdgeEver features and fixes.
