~ the obit ~

Kiwi6 was a free audio host. You uploaded an MP3, you got a direct link and an embeddable player, and that was the entire proposition. Around that core it grew the things an audio host grows if it lasts: artist profiles, podcast feeds, albums with cover art, playlists, listen statistics, comments, private messages. Peter Cai built it in 2009 and kept building it for thirteen years, which is longer than most of the venture-funded services it outlived.

The use case it served best was the one that does not photograph well. If you had a podcast and no budget, or a track you wanted playable inside somebody else's page, you needed a host that gave you a hotlink and did not charge for it. Kiwi6 gave you one. Almost two thirds of a million accounts were opened over its life, and the files behind them add up to 6,880,357 uploads.

At its busiest the service was pushing roughly three gigabits a second of audio out of physical servers in more than one city, holding 46 terabytes, with 1,257,572,226 streams served by the end. Cai put the running cost at "easily thousands of dollars a month depending on load", on top of hardware that cost many thousands more. None of that is remarkable for a company. It is remarkable for one person's side project.

The postmortem is specific about what actually ran out, and it was not enthusiasm. A free audio host in the 2010s accumulates copyright enforcement, abuse prevention, content moderation, privacy compliance after GDPR, customer support, and the software maintenance underneath, all of which arrive as other people's deadlines. Cai also describes being personally harassed over moderation decisions, which is the part of running a public upload service nobody budgets for.

Hosting other people's audio means every takedown is addressed to you by name. Every uploaded file is a bet that it is what it claims to be. A company absorbs that into a team and a legal retainer; one person absorbs it into their evenings.

~ what got deleted ~

The sunset was announced ahead of time and the deletion was total. The notice is still up and lists what went: artist profiles, podcast feeds, embed widgets, hotlinks, albums and album art, listen statistics, comments and private messages, favorites, playlists, private files. "All user data was permanently deleted and can no longer be recovered."

That list is a description of a platform rather than a file dump, and it explains why a Kiwi6 link dying is worse than a dead download. The embed widgets are the real casualty: every forum post and band page that had a Kiwi6 player in it now has a hole where the song was, and the page around the hole usually still works, which keeps the gap visible for years.

~ the honest distance ~

By 2009 I was finishing university and had been on broadband for three years, so the era when I needed somebody else's free host to put an MP3 on a page was already behind me. The habit it served is one I recognize from earlier, from the Turkish forum years when a hardware list in your signature and a file on a free host were how you existed online. Kiwi6 kept that arrangement available for thirteen years after the rest of the web monetized it.

What it left behind is better documented than most dead services manage: a shutdown notice that is still up, and a postmortem with the real numbers in it. Both exist because the person who switched the service off was the person who had written it.
