Periwinkle Simplifies Self-Hosted Social Media on AT Protocol
Berlin startup Periwinkle has launched a managed service that lets individuals and organizations run social media accounts on their own domains using the AT Protocol (the open standard behind Bluesky). The company offers hosted personal data servers (PDS) and domain provisioning, handling updates, backups and monitoring so non-technical users can own their posts, follows and profiles without self-managing servers. Plans include a free tier (500MB) and paid tiers starting at $4/month, with EU or U.S. hosting options and enterprise plans available. Founder Charles Blumenthal is currently solo and self-funded; the product positions Periwinkle as a first-to-market fully managed PDS provider, with competitors such as Blacksky and Eurosky focused on community tooling.
Introduces a managed, self-hosted social infrastructure that gives users and organizations control over social data; relevant to platform competition, data ownership and identity strategies but currently a niche startup release.

W Social launches as European X alternative
W Social, a new Europe-hosted social network operated by W Social AB (a subsidiary of We Don’t Have Time AB), has begun invite-only public beta testing as an alternative to major US platforms. The service names Prof. Dr. Anna Zeiter as CEO and emphasizes mandatory one-time identity verification (ID document + selfie) while allowing pseudonymous display names; submitted personal data are reportedly deleted after verification and only an encrypted token is retained to prevent multiple accounts. Technically the platform uses the AT-protocol (used by Bluesky) to enable interoperable profiles and content. Financing currently comes from roughly 80 private European investors with no EU subsidies; the company’s bylaws reportedly bar takeover by US corporations. Advertising is planned no earlier than 2028 and a micropayment model for unlocking individual content is proposed. The article was published on 2026-06-18.
Acorn launches decentralized community platform for creators
Acorn, a new community platform from Blacksky, launched on May 4, 2026 as an alternative to centralized social networks such as X, Instagram and Threads. Built on the AT Protocol (the tech behind Bluesky), Acorn lets organizations and creators host self‑controlled communities with customizable homepages, starter packs for new members, feed customization, moderation tooling, reputation badges, bot/troll policing, and built‑in analytics. Communities can deploy Acorn on their own domains and optionally run their own Personal Data Server (PDS). Pricing averages about $100–$150 per month today, with plans to transition to a tiered SaaS model. Early adopters include AT Protocol communities Latinsky and Medsky and a filmmaker group called The Invite. Blacksky positions Acorn as a way for groups displaced by platform changes (e.g., X shutting Communities) to retain control over moderation, membership and experience.
Bluesky Adds Long-Form Article Support via Standard.site
Bluesky rolled out a new app version that integrates with Standard.site to surface long-form content across the AT Protocol-powered "Atmosphere." The integration lets Bluesky users discover articles, blogs and newsletters from other AT Protocol apps such as Leaflet, pckt and Offprint; initial presentation will be dynamic link cards with richer previews. The update (Bluesky v1.122) also includes UI improvements (GIF picker, photo viewer), expanded account-level moderation labels and a fix for an iOS video upload bug. The move follows WordPress releasing a plugin to publish to the Atmosphere, further enabling cross-client distribution of blog content. The article contrasts Bluesky’s open-data approach with X’s Articles feature, which is restricted to paid subscribers and businesses and sits inside X’s closed ecosystem.
