Threads review
A familiar public microblogging app with Instagram sharing and optional ActivityPub support.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
Threads is a social networking app from Instagram for sharing text updates and joining public conversations. It suits people who want a mainstream microblogging experience on web or mobile, with familiar public posts and the option to connect with participating fediverse accounts. Users can share links, photos and videos, follow accounts, browse feeds, and manage who can mention or reply to them. The free app is available on web, iOS and Android.
Posts can contain up to 500 characters, while a separate text attachment can reach 10,000 characters. That distinction gives users a concise default format with room for longer text when needed. For discovery, Threads offers For You and Following feeds, plus search for keywords, topics and fediverse profiles. Reply controls and hidden-word filters provide ways to shape conversations. Sharing also extends beyond Threads: posts can be sent to Instagram Stories or shared through links.
Instagram is the clearest ecosystem fit, while optional ActivityPub sharing and interaction connect Threads with compatible fediverse servers. That federation is not required to use the app, though its availability may vary by region or account eligibility. Choose Threads if you want public text conversations, photo and video posts, and Instagram sharing in a free web and mobile app. It is a less suitable choice if your priority is a standard post longer than 500 characters without attaching separate text, or if fediverse access is essential and is not available for your account.
