OpenDrop is an open-source, self-hosted alternative to Cloudflare Drop for publishing static HTML previews and reviewing every version.

Upload a folder or ZIP from the browser or with the npx opendrop CLI, then share a public or private preview. Validation, immutable versioned URLs, point comments, text highlights, replies, and resolved threads keep feedback attached to the exact build and page under review.

Run OpenDrop on your own infrastructure with Bun, SQLite or PostgreSQL, and S3-compatible storage, or deploy the same server to Cloudflare Workers with D1 and R2.
