EdgeEver: An open-source, AI-native Evernote alternative that runs zero-cost on Cloudflare or Docker (with native MCP & full cross-platform apps)

Hi /r/selfhosted! Like many long-time Evernote users, I was frustrated when it grew increasingly bloated, aggressive with paywalls, and slow. I tried Obsidian, but managing sync across devices, dealing with bulky attachment vaults, and missing a classic structured three-pane layout for quick capture left me wishing for a simpler, modern self-hosted setup. So I built EdgeEver (https://github.com/tianma-if/edgeever) — a modern, fully open-source (AGPLv3) knowledge base workspace that combines the classic Evernote-style workflow with zero server costs, open SQLite data ownership, and native AI Agent integration. Key Highlights for Self-Hosters: • Zero-Cost Serverless or Docker: • Cloudflare Free Tier: Runs entirely on Cloudflare Workers + D1 (SQLite) + R2 storage + Pages. With Cloudflare's free tier, a personal instance can easily hold ~150k notes and 50k images with $0 hosting bill. • Docker Compose: For those who prefer running on a home server, NAS, or VPS, a standard Docker container backed by SQLite is fully supported out of the box. • Complete Client Matrix (Not just a web wrapper): • Mobile: Native iOS app (App Store (https://apps.apple.com/us/app/edgeever/id6792625631)) and Android app (Google Play (https://play.google.com/store/apps/details?id=org.edgeever.mobile)). • Desktop: macOS (Apple Silicon & Intel), Windows, and Linux AppImage (GitHub Releases (https://github.com/tianma-if/edgeever/releases/latest)). • Web Clipper: Extensions available for Chrome, Edge, and Firefox. • Native Model Context Protocol (MCP): • Ships with a native MCP server implementation. You can directly connect AI tools (Claude Code, Cursor, Antigravity, etc.) to your self-hosted knowledge base to read, search, and synthesize notes as external memory. • Bring-Your-Own-Key (BYOK) for OpenAI, Anthropic, or Gemini-compatible APIs for in-editor proofreading, continuation, and summarization. • Classic 3-Pane Productivity: • Notebook tree, note list, and dual-view editor (seamless rich text & Markdown source). • Visual diagram canvas for mind maps, flowcharts, and architecture diagrams. • Lossless file attachments up to 1GB with chunked streaming. • Open Data & Complete Portability: • Built on standard SQLite with a full REST API. • One-click lossless ZIP export with standard Markdown, Front Matter, nested folders, relative attachment links, and version histories. No vendor lock-in. Quick Links: • GitHub: https://github.com/tianma-if/edgeever • Live Demo: https://demo.edgeever.org (resets daily) • Tech Stack: Bun, React, Tailwind, Cloudflare Workers/D1/R2, Docker, SQLite. I’d love to hear your feedback, thoughts on the architecture, and feature requests!
