Render your Mermaid or D2 diagram to a self-contained HTML file, then drop diagram.html for a branded, private link on your domain.
How it works with drop
Perfect for circulating a system design for review without posting it to a public service.
1
Drop it
drop file.html — or a PDF, markdown, image, or any file — from your terminal or any AI agent.
2
Branded & encrypted
Your logo, OG card, and badge are baked in, then it's AES-256 encrypted client-side behind your unlock gate.
3
Live on your domain
Uploaded to your Vercel Blob and served at yourdomain.com/slug. URL + password on your clipboard.
FAQ
Is it really open-source and self-hosted?
Yes — MIT licensed, and it runs on your own Vercel Blob + domain. No third party ever holds your content (it's encrypted client-side) or controls your URL.
Is it zero-knowledge?
Locked drops are AES-256 encrypted in the browser via StatiCrypt before upload. The server stores only ciphertext — never your content or password.
Does it work with any AI agent?
Yes. It's a CLI plus a SKILL.md and an MCP server, so Claude Code, Codex, Cursor, OpenCode, Gemini CLI — anything that runs a shell or speaks MCP — can use it.
