Screencasting.comDelivering 15TB of 4K video with Cloudflare R2 for $2.18 - Screencasting.comGrounded web search### Cloudflare R2's free egress ... When Cloudflare's R2 Object Storage launched in 2022, it made a splash due to their claim of completely free egress bandwidth. It sounds too good to be true, but basically Cloudflare R2 offers free egress (data out) because they already pay for a set amount of data to move in and out of their network. Since they mostly use data coming in for services that protect websites, they can afford to let data go out (egress) without charging for it. R2's free tier offe

  • Cloudflare R2: Does it work? - Indie Hackers — ## So far, so good All of the images I uploaded loaded fast (as you can see from this post). So far, I haven't encountered any "surprising" pricing. So I can safely say that Cloudflare R2 works as advertised.
  • Comparing AWS S3 with Cloudflare R2: Price, Performance and User Experience / Hacker News — Reading around online, it seems egress is free until Cloudflare asks for big bucks or threatens to terminate your service. It's probably fine for hobbyists or small web sites. But as a business, I would never trust something that is "free". There has to be a catch somewhere. A business contact of mine asked Cloudflare for a quote for setting up a CDN for 7B requests per month. They dragged him through five sales calls to eventually deliver an offer with request costs 30% above CloudFront's publi
  • Ask HN: Have you used Cloudflare R2? / Hacker News — yes. I use it for my image storage on a small Mastodon instance (https://s.o2l.ie). No issues with it so far, and all is good. Bucket is around 18Gb (was around the 70Gb last month) and bill for last month was 60c for an average of 49.3Gb stored over the
  • Delivering 15TB of 4K video with Cloudflare R2 for $2.18 / Hacker News — Cloudflare R2 has been huge for my open source project Argos Translate. Two years ago I was getting swamped with $250/mo+ bandwidth bills for a project with minimal revenue. Now I distribute 10TB+ per month of model weights for $0. I'm still on the free plan
