We looked at S3 first — it's the obvious default and the DX is solid. But egress fees are a hidden tax that quietly compounds as your user base grows. Every file your users download costs you extra, and it adds up fast.
R2 gives you the exact same S3-compatible API, so there's no learning curve and no SDK migration. We literally just updated our config. Zero egress costs since day one, backed by Cloudflare's global network we were already using. It wasn't even a close call.
Hey Product Hunt 👋
I work with founders on launches every week. And every time a big CVE hits the news, someone in the chat asks "wait, are we affected?"
Most of us have no idea. CVE databases list everything and read like legal docs.
Zero Wire is Cloudflare's fix for that. It's a free vulnerability news wire inside Cloudflare Radar, and it only covers the critical stuff in Internet-facing software.
Every briefing tells you what happened, who should check, and what to do now. In plain English.
Sources are linked right there (CVE records, vendor advisories, CISA KEV), so you're not just trusting a summary.
My favorite part: each briefing comes with a prompt you paste into your AI agent. It runs a read-only check of your setup and tells you what's exposed and what to do next.
Copying it doesn't scan or change anything.
No signup, and you don't need to be on Cloudflare. Check out more https://blog.cloudflare.com/zero-wire/
@kate_ramakaieva Congrats on the launch Making CVE updates easier to understand and act on is a really useful idea.
