Tumblr Hack Day, March 2026 Edition

Once again, it was Hack Day at Tumblr, our favorite excuse to pause the roadmap for a moment and build something weird, useful, or ideally both. Here is a sneak peek of what the team built.

Unified Inbox

@ex, @kostastsi4 and @alexjf worked on making Asks and Submissions easier to find in the apps, moving your Inbox (currently buried in blog settings) to a tab in the Activity screen, where all your other incoming communication lives.

Gifs in replies

In @elt’s opinion, replies could use some spicing up. So he spent Hack Day adding GIF support to replies. Neat! 

Fun fact: reply threads themselves actually started as a Hack Day project over two years ago. The circle of hack life continues. 

Scaling the Reblog Graph Explorer

@blowery improved the implementation of reblog graph to handle massive viral posts gracefully. Instead of struggling with very large reblog chains, this hack rethinks how the graph is laid out so it can handle posts with massive numbers of reblogs more smoothly, making it easier to explore how posts spread across Tumblr.

In-Blog Search Filters

Web had the most complete set of in-blog search filters. Android and iOS? Not so much. @lesianlen worked on bringing parity across all three platforms: Android got Top/Recent sorting, an original posts filter, and Ask and Chat post type filters. iOS went from zero filters to a brand-new bottom sheet with the full filter set. Now everyone gets to search their blog properly, regardless of platform. 

Separating in-blog search from "Exclude from Tumblr Search and Recommendations"

Did you know that selecting the “Exclude from Tumblr search and recommendations” setting would also disable your in-blog search? Well, thanks to @lesianlen, now it doesn’t. This one’s already live.

Communities: Granular Moderator Permissions and Promotion Flow 

Promoting a member to admin in a Community is a big deal (and currently irreversible). 

@straku ironed out the promotion flow, adding a simple step to alert, confirm, and prevent promotions that could be to moderation.

Another request is having more control over what moderators can do. A way to give moderators more power, without them overtaking the community admin.

@jubs built a permissions system that lets admins choose what their moderators can do, without compromising their own ownership. In addition to existing moderator permissions, such as removing posts, and comments, you'd be able to allow mods to edit the community appearance (title, description, etc), the community settings (auto-moderation, tags, etc), and even manage other moderators.

Memories in Profile Page & Archive Page

Inspired by Google Photos’ “Memories” feature, Sowmia proposed building a “Memories” experience for the blog to surface nostalgic posts from its history.

The idea was to create a dedicated Memories feature and link it to archive pages, enabling users to rediscover past content in a more engaging way. As part of the hackday, she implemented the archive page portion of this idea, laying the foundation for integrating the full Memories experience in the future.

Post launcher with shortcuts to Drafts and Queue

@ex tried a new version of the post launcher at the top of the dashboard on web: switch blogs before opening the editor, or jump straight to your Drafts or Queue (takes 3-4 clicks to get there now). The buttons also show how many posts you have in your Drafts and Queue.

Reblogs with Videos

After all, why not? Why shouldn’t we have videos in reblogs? @andriibuilds dared to ask. And build it.

Like Sorting

People with thousands of Tumblr likes have been asking for the ability to sort and organize them for years. To start, @andriibuilds prototyped sorting options for the Likes page.

RemindMe

Inspired by Reddit's RemindMe bot, @data-science-from-the-trenches built a native reminder system: reply to any post or thread with "RemindMe! 2 days" and you'll get an activity notification linking back to it when that time has passed.

The Mysterious Cat Asks

As a preparation for April Fools, @jubs introduced asks sent by the Mysterious Cat, when you eat an "ask" food in the Snek game. Each question was represented by an item, with its own rarity.

And that’s a wrap on Tumblr Hack Day, March 2026 Edition. Huge shout-out to everyone who spent this time building cool things, sharing demos, and reminding us how much fun it is to make Tumblr weirder, better, and more delightful. 

Keep an eye on @changes to see if any of these hacks make it out to you.

Tumblr Advisor Board

I think it could be cool to put together a board of the top Tumblristas in the world, that could see previews of what's coming up and advise on strategic direction. Who should be on it?

Okay, look. We're gonna do it like this, Matt. I used to work in market research. This one is free, next time I expect a month of free premium and if there's a third time I expect a job.

TO EVERYONE ELSE:

A series of ten reblogs is about to follow, since you can only have one poll per reblog. Please answer all ten polls. If you don't see them all, check the notes (this shouldn't take me long so if it's more than like, fifteen minutes since I posted this one they should all be there.)

In the following question, "pre-social media" refers to platforms like LiveJournal, forums, alt.net boards, early MySpace, and similar spaces.

Reblogs in a chain now get their own notes

The reblog chain is one of the things that makes Tumblr unlike anywhere else. All the notes on reblogs are attributed to the original post, no matter which branch people actually liked or reblogged. We want to keep encouraging conversations, and give contributors the recognition they deserve. 

Soon, you'll be able to like, reblog, or reply to any part of a reblog chain, and that note will go to that reblog's author. Each reblog will have its own counts, instead of one aggregated number from every version of the post. And yes, you’ll be able to like multiple posts in one chain.

If a reblog doesn't add anything, the love flows up to the last person in the chain who did. Your post doesn't lose notes just because people spread it quietly.

Past notes will stay on the original post — we're only changing what happens from here on out. Retroactively re-attributing all of them would be... a lot.

This is just the beginning. More changes are coming as we keep building this out – stay tuned!

It’s very clear that you all have strong feelings about Tumblr and about this change. We hear you. The passion people have for how Tumblr works is one of the things that makes this place special.

As this rolls out over the next few days and you explore it, we’ll keep reading your replies and reblogs, so please keep sharing your questions, concerns, and ideas.

Your creativity has always been the heart of Tumblr, whether you’re the original poster or adding something brilliant in the reblogs, and nothing about this change is meant to limit that.

If you’d like to talk directly beyond the comments, leave a reply and we’ll follow up with as many of you as we can. We want to work with you to make Tumblr better.
