Frisk

Frisk is a lightweight file upload and sharing service in the same vein as uguu.se and catbox.moe. The main page works with no signup: pick a file, drag it in, or paste it straight from the clipboard with Ctrl+V, and you get back a direct share link. Files can also be pulled in from a remote URL instead of uploaded from your device.

Accounts are optional. Registering (behind a simple text captcha) adds a dashboard listing your uploads with their links and expiry times, so you can keep track of what you've shared and how long it will stay up.

Uploads are capped at 2 GB per file, with a rolling 4 GB allowance per 24 hours. Retention is tied to how much a file is actually used rather than a fixed clock: files are kept 14 days by default, extended to 40 days if they pass 30 visits within the first two weeks, while files that are never downloaded are removed after 24 hours. Expired uploads are cleaned up automatically, and everything is stored losslessly compressed, so files come back down exactly as they went up.
