Feed-Id in User Agents

At Superfeedr, we’re selfdogfooding. When we started looking at the User-Agents of services polling our feeds, we found numerous interesting things. One of them is that several feed reader do include a feed-id in the User-Agent strings. This is quite convenient for debugging purposes and we also believe it should...  

How to implement PubSubHubbub

PubSubHubbub is a free, open and decentralized protocol. It relies on webhooks to push feed updates in real-time from publishers to subscribers (feed readers). Most importantly, PubSubHubbub builds on existing infrastructure: implementing it won’t change or break your current polling infrastructure, and if for some reason something fails, you can...  

Who fetches our blog feed

A couple weeks ago, we moved this static blog from github pages to Amazon S3. The move itself was uneventful, as both plaforms handle CNAME’s pretty well. However, S3 provides a feature that we needed: redirects. We wanted to redirect our feed address to an app which we could use...

Podcast is RSS

2014 was the biggest year for Podcasts to date. Of course, this came from massively popular shows: This American Life and Serial come to mind, but more importantly, it came from the incredibly long tail of smaller or even niche podcasts thousands of indie people create out there. Platforms like...  

New Year, new hires

Happy new year! 2014 has been a fantastic year for Superfeedr with a lot of new customers consuming our feed APIs, a complete redesign, as well as a lot of great backend changes to help us scale further and further every month. We’re incredibly excited about 2015 and we can’t...  

Replaying Notifications

Debugging webhook patterns is tricky because they’re mostly asynchronous: the subscribing (which listens to the webhook) side usually does not control the publishing side (which triggers the webhook). To help with that, we usually recommend our customers to check this very simple publishing application and its feed. They provide a...  

More Feed Metadata

All RSS/Atom feeds aren’t born equal. As we process more and more we start to have a better understanding of them and one of our goals is to share more of the knowledge with our customers. We’ve been working on extracting more meta-information from these feeds and today, we want...
