Share it. Gone in an hour.

Upload a file to your own Cloudflare R2 bucket and hand a coding agent a short link that stops working on its own. Need it again? Refresh the same link.

Built for handing files to coding agents.

Short + direct

Eight characters, served as the raw file with the right content type. No redirects, no login.

Self-expiring

One hour by default, set globally or per upload. Close a link early or cap its downloads.

Yours alone

One Worker, one Durable Object and a private bucket in your own Cloudflare account.

Already set up?

$ fl init --endpoint https://fl.example.com

$ fl revoke k3F9xQ2m

Run your own.

A personal, single-user tool, so there is nothing to sign up for here. Deploy it to your own Cloudflare account; the free plan is enough.

$ git clone https://github.com/crcatala/flashlink
$ cd flashlink && pnpm install
$ pnpm --filter @flashlink/worker exec wrangler login
$ pnpm setup:cloudflare
