Overview
CloudPaste is a serverless, self-hosted file manager and text-sharing tool built on Cloudflare. It combines a pastebin-style Markdown editor with a multi-storage file drive and a WebDAV server, so you can share notes and files and mount many storage backends as one network drive — all without running a server.
Key Features
Cloudflare-native architecture
- Runs on Workers, Workflows, and D1, served from Cloudflare’s global network
- Single-Worker deployment with frontend and backend together, or split them if you prefer
- No servers to maintain, with automatic scaling
Multi-storage support
- S3-compatible storage: Cloudflare R2, Backblaze B2, AWS S3, Alibaba Cloud OSS, Tencent COS, MinIO, and more
- Other backends: WebDAV, OneDrive, Google Drive, Telegram, Discord, Hugging Face, and GitHub (read-only)
- Smart uploads: presigned direct uploads, streaming, and resumable chunked uploads with live progress
- Previews for 30+ formats, including images, video, audio, PDF, Office documents, code, and e-books
Markdown editor and sharing
- Rich Markdown editing with math, flowcharts, and mind maps
- Export to PDF, HTML, PNG, or Word
- Shares protected by password, expiry time, and view limits
- Raw links for hosting config files, similar to GitHub Raw
WebDAV and permissions
- Mount everything as a WebDAV network drive in any client
- API keys scoped to specific storage paths with read/write permissions and expiry
- Admin authentication with JWT, plus an installable PWA
Getting Started
You need a Cloudflare account; if you use R2, enable it and create a bucket first.
- GitHub Actions (recommended): fork the repository, add your Cloudflare account ID and API token as repository secrets, and run the deploy workflow — it creates the D1 database and deploys the Worker.
- Manual: deploy with the Wrangler CLI.
- Docker: frontend and backend images with a Docker Compose file, including local-disk storage.
After deployment, sign in as the administrator and add your storage configurations from the dashboard.
Use Cases
- A personal or team pastebin with expiring, password-protected links
- One web and WebDAV front end for several cloud storage accounts
- Lightweight file sharing without paying for a VPS
