Tumblr Hack Day, January 2026 Edition
Hack days are when our team gets to step away from the regular roadmap and work on whatever ideas they so desire. Here’s a taste of what came out of it:
Advanced Search
We added advanced search operators in a previous Hack Day. This time, @lesianlen added an exclusion operator to exclude posts that contain a specific word, phrase, or tag. @ex and @blowery helped out to add a spiffy modal that shows exactly how you can use all available advanced search operators.
Search in Communities
Speaking of search, @lesianlen also worked on adding search within individual Communities to find posts and conversations.
“Latest Comments” Community feed
@jubs and @lesianlen worked on creating a tab within individual communities that bumps a post to the top when someone adds a comment. Easily find posts where conversation is hot!
Nudge to Add Moderators
When your community is growing, you need more people to help run it. @jubs worked on a reminder that suggests just that.
iOS Home Screen Widgets
Ben worked on widgets with quick actions and Radar, making Tumblr even more accessible on your home screen.
iOS Shortcuts and Siri Support
@kostastsi4 explored making Tumblr play more nicely with your iPhone: showing quick links in Spotlight to jump straight to your Dashboard, Messages, Activity, or your blog. He also began adding support for Siri and Shortcuts to open specific tabs, start a new post, or search for exactly what you want.
Suggest Tags Based on Post Content
Tumblr runs on tags. However, picking the right tags for your post can be difficult unless you’re a Tumblr expert. Our current tag suggestions are a combination of tags you follow, tags you’ve used before, and some trending tags. @arandomblog31 worked on suggesting better tags based on the post you’re writing.
Reblog Explorer
Ever wondered how a post spread across Tumblr? @blowery built a full-screen version of the reblog graph view that lets you explore how a post traveled. Click through the graph to see the full reblog trail update in real-time explore different branches. There’s even keyboard navigation — press the up arrow repeatedly to follow the most popular reblog path through the entire graph, or walk backwards toward the original post to see what tags people added along the way.
Identities
@elt began exploring what it would take to eliminate the limitations of secondary blogs.
Some of these will be rolling out soon, others need a bit more time in the oven. Keep an eye on @changes to see when they arrive!
