Beyond Bluesky: These are the apps building social experiences on the AT Protocol

A year ago, Bluesky was opening up to the public and was known as one of the many X competitors that emerged after Elon Musk acquired the network formerly known as Twitter. Today, Bluesky’s social network has grown to over 33 million users, while the technology it’s built upon — the AT Protocol (or ATProto for short) — is being used to develop dozens more applications designed to work together as part of an open social web.

The developers behind many of these apps attended the first conference dedicated to the AT Protocol, ATmosphere, held in Seattle last weekend. There, they learned what’s ahead for ATProto, what challenges still need to be overcome, and what other things they’ll need to think about as they build for this new social app ecosystem. Others attended online, watched the talks and presentations remotely, and participated in a growing Discord chat for community members.

The ATProto community is working to rebuild Web 2.0, an earlier version of the social web that included social media websites, blogs, wikis, video- and photo-sharing sites, and other collaborative and hosted services. Except this time around, the apps are being built on open technology, not siloed into centralized services that tend to be operated by tech giants.

Bluesky was the first of these services to emerge, but if the open social web movement has any staying power, it won’t be the last.

Below is a list of AT Protocol-based, consumer-facing apps that are either built on top of Bluesky or its underlying protocol, allowing users to take back control over their social networking experiences and personal data. Many of these are still in early development but showcase the potential for what’s ahead in this expanding ecosystem.

This is a work in progress! Apps are still being added. Feeling left out? Email [email protected]. (Note that this list is focused on consumer-facing apps people can use now, not small projects or dev tools.)

Flashes

Flashes is an Instagram alternative based on Berlin developer Sebastian Vogelsang’s earlier app, Skeets, a Bluesky client. Launched publicly at the end of February, Flashes grabbed 30,000 downloads in its first 24 hours for offering a classic Instagram experience. Users can upload up to four photos or videos of up to 3 minutes in length, up from 1 minute previously, thanks to an update Bluesky released. The app offers photo filters, curated feeds from artists, custom feeds, and a Portfolio Mode where photographers can showcase their work.

Spark

Spark (originally called Reelo) is a video-first app that is built on top of the AT Protocol, not just Bluesky. That allows the app to differentiate itself with a broader feature set that will include support for longer videos, filters, effects, a music library, and, eventually, livestreaming.

Built by Seattle-based co-founders Victoria (“Tori”) White and Reed Harmeyer, Skylight is built on top of Bluesky, offering features such as likes, follows, comments, and profile pages. Users can follow the app’s active development on its co-founder’s TikTok page as the team adds more features, including video support.

The app is in testing on iOS and Android.

Pinksky

Pinksky is another one of many apps trying to build an alternative to Instagram using ATProto. Built by developer Ramon Souza, the app is available on both iOS and Android and will focus mainly on photo-sharing, like classic Instagram did. The app offers similar features to Instagram, including user profiles, a feed of photos and videos, and a Stories section where posts remain visible for 24 hours.

Bluescreen (TikTok alternative)

Bluescreen, also built by Vogelsang, is an upcoming app that will focus on videos posted to the Bluesky social network.

Videos for Bluesky

The generically named Videos for Bluesky is another app built on top of Bluesky from “MszPro,” aka Hoshida Takiyoshi, an indie Japanese developer. Like others, Videos for Bluesky lets you browse videos posted to the Bluesky social network by vertically scrolling in a TikTok-like user interface with familiar Like, Repost, and Reply buttons.

Livestreaming

Streamplace

Streamplace is the first livestreaming video service built on top of the AT Protocol. The service, which was recently used to livestream the ATmosphere conference in Seattle, offers a familiar streaming experience with support for high-quality videos, livestreaming, clips, and uploads. All the video content is also cryptographically signed by creators and respects their consent preferences. It is built on the same public key infrastructure as decentralized social networks.

Founded by Eli Mallon, Streamplace was initially backed by his previous employer, Livepeer (another decentralized video platform), which operated a crypto treasury where funds are invested into other projects. That allowed him to get Streamplace off the ground. Now he sees potential in building out a technology that could appeal to creators like Twitch streamers, who would rather connect directly with fans through their own app or website instead of having to split their revenue with Twitch owner Amazon.

Feed builders

Graze

Graze is a startup that lets you easily build, customize, publish, and manage Bluesky feeds and, eventually, monetize them with ads, sponsored posts, and subscriptions. The service is working with the Bluesky firehose, aka the Jetstream, which includes all the public posts on the social network.

Surf

Flipboard app — **Image Credits:**Flipboard/Surf

Flipboard’s newest app, Surf, lets you build your own custom feeds from across the open web, including not only Bluesky but also Mastodon, RSS, and more. That means you can mix in news articles, blog posts, podcasts, and YouTube feeds into the custom feeds you build in Surf, alongside social posts. You can then use Surf to browse your feeds and others from the community across a range of topics and interests. Surf is still in private beta testing, but a signup list is available.

SkyFeed

A web-based, TweetDeck-like client for Bluesky, SkyFeed lets you create a dashboard of your feeds and profiles. However, most of its users come to SkyFeed because it also offers an easy way for even nondevelopers to build custom feeds based on lists or regexes.

Germ

Germ’s big idea is not just to offer an alternative to your phone messages, like Signal, but to build a social platform where you could discover and connect with others for any reason: marketplace exchanges, dating, social networking, and more. However, it would be one where you were in control of the data you were sharing and could stop that sharing at any time.

Currently an end-to-end encrypted messenger that you can download from the App Store, Germ lets you build and share multiple identities. Plus, you can start chatting with someone on Germ even if they don’t have the app installed, thanks to its use of Apple’s App Clips technology. This allows you to have a lightweight app experience on your iPhone before you download the full application from the App Store.

Germ was founded by writer and Stanford lecturer Tessa Brown (CEO) and former Apple privacy engineer Mark Xue (CTO). The team is now working on a Bluesky integration that would allow users to chat securely with their Bluesky friends.

Roomy

A peer-to-peer messaging app built on the AT Protocol, Roomy is similar in some ways to Discord but taps into open standards. For instance, ATProto is used for social discovery, while Automerge is used for peer-to-peer discovery. The app is backed by funding from Skyseed and is currently in alpha testing.

You can log into Roomy with your Bluesky account and direct message other users to engage in chats. The messages are encrypted, but this is an experimental project and not audited, so be aware. Plus, some non-encrypted metadata shows who you were talking to but not the contents of those messages. (In other words, don’t swap out Signal for Roomy yet.)

Dazzle.fm

Founded by former Stability AI engineer John Sabath, Dazzle offers a website that makes sense of the firehose of data from Bluesky and organizes it into categories, highlighting the trends across various topics. While much of the early discussion on Bluesky today leans political, Dazzle’s site can help you find other topics and conversations taking place.

Dazzle lets you give it instructions to tune the site to your own interests, too. You could ask it to show you a topic but without any posts featuring political discussions, for example. That means you could use Dazzle to show you local news, but not national politics, or you could keep your experience focused only on those who are posting with a positive sentiment.

The idea is that you’ll be able to switch between these different modes, generated using AI technology, without actually having to build custom feeds. Instead, you can just type in what you want to see (or not see) into a chat-like interface, then have Dazzle reconfigure itself to offer you posts that match whatever “vibe” you had just requested.

Sill

Link aggregation service Sill lets you keep up with what everyone’s talking about on alternative social media sites like Bluesky and Mastodon in one place. The service is similar to the older startup Nuzzel, which was acquired by Twitter as part of its deal for Scroll in 2021, then integrated into Twitter’s app. Popular with news junkies, Nuzzel helped users keep track of what everyone on Twitter was talking about, reading, and resharing that day.

Sill is also among the early adopters using Bluesky’s OAuth for the AT Protocol instead of app passwords, making it easier to log in. Once connected, you’ll see the most shared links across your services and the resulting conversations.

Frontpage

A decentralized and federated link aggregator built on ATProto, Frontpage offers a simple interface for organizing and upvoting interesting posts and links being shared across the social network. It also supports commenting and notifications.

Alternative Bluesky Clients

Skeets

Also by Vogelsang, Skeets is an alternative to Bluesky’s main app that’s optimized for accessibility and works well on both iPhone and iPad.

Deck.blue

Another TweetDeck-style web app, Deck.blue lets you fill your screen with columns featuring your Home feed, Notifications, custom feeds, lists, and more. The app also supports multiple accounts and the scheduling of posts.

Events

Smoke Signal

An event and RSVP management system, Smoke Signal is the Bluesky alternative to something like Eventbrite or Facebook Events. Built on top of ATProto, Smoke Signal supports OAuth, allowing users to discover communities and create and RSVP to events while also keeping hold of their own personal data.

Blogging

White Wind

A Markdown blogging service for the AT Protocol, White Wind lets you use your ATProto account to log in, then write in Markdown. The service includes tools for uploading images, previewing your post, and more, with everything stored in your account’s PDS (personal data service). When you post on Bluesky, those replies are included on your blog automatically.

Analytics

BlueSkyHunter

Largely a growth and analytics toolset for Bluesky, BlueSkyHunter also offers a way to tap into trends on the social network. One section in the app called Viral Posts showcases the more popular posts. This could help content planners pick up on trends and memes or find templates that are popular with other users that they could adopt.

Fedica

Fedica offers an online dashboard that allows you to compose and schedule posts across social networks, including Bluesky, Threads, X, Mastodon, and Pixelfed, among others. It also supports more traditional social apps like Facebook, Instagram, TikTok, Pinterest, and YouTube. Included in its plans are a variety of features for social listening, tools for tracking hashtags, keywords, and post reach, as well as those for follower analysis.

Pintarnya raises $16.7M to power jobs and financial services in Indonesia

Pintarnya, an Indonesian employment platform that goes beyond job matching by offering financial services along with full-time and side-gig opportunities, said it has raised a $16.7 million Series A round.

The funding was led by Square Peg with participation from existing investors Vertex Venture Southeast Asia & India and East Ventures.

Ghirish Pokardas, Nelly Nurmalasari, and Henry Hendrawan founded Pintarnya in 2022 to tackle two of the biggest challenges Indonesians face daily: earning enough and borrowing responsibly.

“Traditionally, mass workers in Indonesia find jobs offline through job fairs or word of mouth, with employers buried in paper applications and candidates rarely hearing back. For borrowing, their options are often limited to family/friend or predatory lenders with harsh collection practices,” Henry Hendrawan, co-founder of Pintarnya, told TechCrunch. “We digitize job matching with AI to make hiring faster and we provide workers with safer, healthier lending options — designed around what they can reasonably afford, rather than pushing them deeper into debt.”

Around 59% of Indonesia’s 150 million workforce is employed in the informal sector, highlighting the difficulties these workers encounter in accessing formal financial services because they lack verifiable income and official employment documentation.

Pintarnya tackles this challenge by partnering with asset-backed lenders to offer secured loans, using collateral such as gold, electronics, or vehicles, Hendrawan added.

Since its seed funding in 2022, the platform currently serves over 10 million job seeker users and 40,000 employers nationwide. Its revenue has increased almost fivefold year-over-year and expects to reach break-even by the end of the year, Hendrawn noted. Pintarnya primarily serves users aged 21 to 40, most of whom have a high school education or a diploma below university level. The startup aims to focus on this underserved segment, given the large population of blue-collar and informal workers in Indonesia.

“Through the journey of building employment services, we discovered that our users needed more than just jobs — they needed access to financial services that traditional banks couldn’t provide,” said Hendrawan. “We digitize job matching with AI to make hiring faster and we provide workers with safer, healthier lending options — designed around what they can reasonably afford, rather than pushing them deeper into debt.”

While Indonesia already has job platforms like JobStreet, Kalibrr, and Glints, these primarily cater to white-collar roles, which represent only a small portion of the workforce, according to Hendrawan. Pintarnya’s platform is designed specifically for blue-collar workers, offering tailored experiences such as quick-apply options for walk-in interviews, affordable e-learning on relevant skills, in-app opportunities for supplemental income, and seamless connections to financial services like loans.

The same trend is evident in Indonesia’s fintech sector, which similarly caters to white-collar or upper-middle-class consumers. Conventional credit scoring models for loans, which rely on steady monthly income and bank account activity, often leave blue-collar workers overlooked by existing fintech providers, Hendrawan explained.

When asked about which fintech services are most in demand, Hendrawan mentioned, “Given their employment status, lending is the most in-demand financial service for Pintarnya’s users today. We are planning to ‘graduate’ them to micro-savings and investments down the road through innovative products with our partners.”

The new funding will enable Pintarnya to strengthen its platform technology and broaden its financial service offerings through strategic partnerships. With most Indonesian workers employed in blue-collar and informal sectors, the co-founders see substantial growth opportunities in the local market. Leveraging their extensive experience in managing businesses across Southeast Asia, they are also open to exploring regional expansion when the timing is right.

“Our vision is for Pintarnya to be the everyday companion that empowers Indonesians to not only make ends meet today, but also plan, grow, and upgrade their lives tomorrow … In five years, we see Pintarnya as the go-to super app for Indonesia’s workers, not just for earning income, but as a trusted partner throughout their life journey,” Hendrawan said. “We want to be the first stop when someone is looking for work, a place that helps them upgrade their skills, and a reliable guide as they make financial decisions.”

OpenAI warns against SPVs and other ‘unauthorized’ investments

In a new blog post, OpenAI warns against “unauthorized opportunities to gain exposure to OpenAI through a variety of means,” including special purpose vehicles, known as SPVs.

“We urge you to be careful if you are contacted by a firm that purports to have access to OpenAI, including through the sale of an SPV interest with exposure to OpenAI equity,” the company writes. The blog post acknowledges that “not every offer of OpenAI equity […] is problematic” but says firms may be “attempting to circumvent our transfer restrictions.”

“If so, the sale will not be recognized and carry no economic value to you,” OpenAI says.

Investors have increasingly used SPVs (which pool money for one-off investments) as a way to buy into hot AI startups, prompting other VCs to criticize them as a vehicle for “tourist chumps.”

Business Insider reports that OpenAI isn’t the only major AI company looking to crack down on SPVs, with Anthropic reportedly telling Menlo Ventures it must use its own capital, not an SPV, to invest in an upcoming round.

Meta partners with Midjourney on AI image and video models

Meta is partnering with Midjourney to license the startup’s AI image and video generation technology, Meta Chief AI Officer Alexandr Wang announced Friday in a post on Threads. Wang says Meta’s research teams will collaborate with Midjourney to bring its technology into future AI models and products.

“To ensure Meta is able to deliver the best possible products for people it will require taking an all-of-the-above approach,” Wang said. “This means world-class talent, ambitious compute roadmap, and working with the best players across the industry.”

The Midjourney partnership could help Meta develop products that compete with industry-leading AI image and video models, such as OpenAI’s Sora, Black Forest Lab’s Flux, and Google’s Veo. Last year, Meta rolled out its own AI image generation tool, Imagine, into several of its products, including Facebook, Instagram, and Messenger. Meta also has an AI video generation tool, Movie Gen, that allows users to create videos from prompts.

The licensing agreement with Midjourney marks Meta’s latest deal to get ahead in the AI race. Earlier this year, CEO Mark Zuckerberg went on a hiring spree for AI talent, offering some researchers compensation packages worth upwards of $100 million. The social media giant also invested $14 billion in Scale AI, and acquired the AI voice startup Play AI.

Meta has held talks with several other leading AI labs about other acquisitions, and Zuckerberg even spoke with Elon Musk about joining his $97 billion takeover bid of OpenAI (Meta ultimately did not join the offer, and OpenAI denied Musk’s bid).

While the terms of Meta’s deal with Midjourney remain unknown, the startup’s CEO, David Holz, said in a post on X that his company remains independent with no investors; Midjourney is one of the few leading AI model developers that has never taken on outside funding. At one point, Meta talked with Midjourney about acquiring the startup, according to Upstarts Media.

Midjourney was founded in 2022 and quickly became a leader in the AI image generation space for its realistic, unique style. By 2023, the startup was reportedly on pace to generate $200 million in revenue. The startup sells subscriptions starting at $10 per month. It offers pricier tiers, which offer more AI image generations, that cost as much as $120 per month. In June, the startup released its first AI video model, V1.

Meta’s partnership with Midjourney comes just two months after the startup was sued by Disney and Universal, alleging that it trained AI image models on copyrighted works. Several AI model developers — including Meta — face similar allegations from copyright holders, however, recent court cases pertaining to AI training data have sided with tech companies.
