Dominik Biedebach @bdbch.com · 09/08/2026Is there an easy way to see blob size limits for PDSs? I'm currently building a prototype for a Curseforge alternative and would love to know if my release zips would hit the platform limits. 330
fry69 @fry69.dev · 09/08/2026Latest reference PDS should enable `describeServer`, which shows this limit. See -> atproto.com/blog/pds-cus... 072
![We’ve also enabled the PDS to advertise its maximum blob size via describeServer, so clients can split or reject uploads if desired:
curl -s https://maitake.us-west.host.bsky.network/xrpc/com.atproto.server.describeServer | jq
