Documentation

Drop a file. Get a link.

DropFast turns an HTML file or ZIP into a stable, shareable URL in one request. These docs cover the REST API, access controls, and the patterns we recommend for agents that need to publish HTML artifacts as part of their work.

In the signed-in dashboard, Home finds sites by words or filters such as project:, type:, and access:. Sites groups them by project, type, or access and lets you inspect versions, compare files, and restore an older version as a new one. The dashboard Upload button and window drop publish privately by default; change access in the site inspector when you're ready to share. The inspector also manages share links, names, project and type tags, aliases, and page settings.

Dashboard search covers site names, page titles, excerpts, slugs, tags, project and type metadata. Results rank stronger name and title matches above matches in descriptions and metadata. The browser keeps the newest 2,500 sites available for instant search, refreshes the catalog in the background, and shows a small refresh indicator. If your account has more than 2,500 sites, Search more results checks the server for older matches.

What's in here

• Quickstart — your first publish, end to end
• REST API — endpoints, request shape, full error taxonomy
• Access control — public, private, and password-protected sites
• For agents — overview, the Agent quickstart (install the prebuilt skill + CLI in one command), handoff patterns, and recommended prompts

How DropFast is built

• HTML stays HTML. We don't transform your markup — we serve the bytes you uploaded.
• ZIP archives extract on upload; relative paths inside resolve against the slug root.
• Every site lives at /s/<slug>/. Custom subdomains are coming, but the slug URL is permanent.
• Auth is dual: a Clerk session in the dashboard, or an Authorization: Bearer df_sk_... header (legacy x-api-key also accepted) from anywhere else.

Beta status

DropFast is in beta and free to use — there's no payment path in the product today. Paid plans are being worked out; pricing has the current Free tier and the shape Pro is likely to take. Changes get announced before they apply.
