Aaron Vegh and Ben Rice McCarthy (of Obscura renown) have teamed up to create Croissant, a new app — currently iPhone-only — for cross-posting to Mastodon, Threads, and Bluesky. 15 years ago I wrote “Twitter Clients Are a UI Design Playground” and that piece stands up, but it’s not Twitter/X in particular (certainly not anymore — X support is conspicuously omitted from Croissant’s current lineup up supported platforms), but tweet-like platforms in general. Croissant proves that this domain remains a UI playground. It’s both visually distinctive and intuitively familiar, with a fun and fluid UI. It’s the sort of app that I want to find reasons to use.

Free to download and try with a single account; $3/month, $20/year, or $60 as a one-time purchase for multi-account support, which is where Croissant really shines.
