The Open-Source Framework for Real-Time Audio and Video at Scale

Real-time communication powers the modern digital world, from virtual healthcare and remote education to online gaming and live broadcasting. Today’s users expect seamless, low-latency, high-quality media experiences across devices. For developers building these applications, selecting the right communication infrastructure is critical. That’s where LiveKit comes in.

LiveKit is an
open-source platform that provides the building blocks for
real-time audio and video apps. With support for
WebRTC,
AI integrations, and
flexible deployment options (cloud or self-hosted), LiveKit helps developers build scalable, production-grade communication tools that meet the highest standards for performance and privacy.


What Is LiveKit?

LiveKit is a real-time communication framework designed to simplify the creation of interactive audio and video applications. Built on WebRTC, LiveKit provides:

  • A robust media server
  • Client SDKs for multiple platforms
  • End-to-end media encryption
  • AI integration support
  • Cloud and self-hosted deployment models

Unlike many closed, vendor-locked platforms, LiveKit’s
open-source model gives developers complete control over infrastructure and customisation, allowing for tailored experiences across industries.

How Does LiveKit Work?

At the core of LiveKit is an SFU (Selective Forwarding Unit), which efficiently routes video and audio streams without decoding or re-encoding them. This keeps latency low and CPU usage minimal, especially during group calls or interactive broadcasts.

LiveKit’s architecture includes:

  • Client SDKs: Available for JavaScript, iOS (Swift), Android (Kotlin), Flutter, Unity, React Native, Node.js, Go, and Rust.
  • Room and Participant Management: APIs to create, manage, and moderate rooms and users.
  • Track-Level Controls: Fine-grained control to mute, pause, or adjust specific streams dynamically.
  • Webhooks and Events: For integration with third-party tools like analytics, moderation, or AI services.
  • Recording & Streaming: Capture sessions and broadcast them to platforms like YouTube, Twitch, or private servers.

Deployment Options: Cloud or Self-Hosted

LiveKit offers two deployment options to suit different levels of control and scalability:


1. Self-Hosted     


Deploy on your own infrastructure using Kubernetes, Docker, or custom configurations. This is ideal for teams with:

  • Strict
    compliance requirements (HIPAA, GDPR, etc.)
  • Specific
    scaling strategies
  • Custom
    AI workflows
  • Full control over
    data handling

2. LiveKit Cloud 


A

fully managed service hosted by LiveKit. It offers:

  • Instant setup
  • Automatic scaling
  • Usage-based pricing
  • A generous free tier

Perfect for startups, MVPs, and teams that want fast time-to-market without managing servers.

Scalability and Performance

LiveKit was designed for high performance under demanding workloads:

  • End-to-End Encryption (E2EE): Ensures complete privacy, even LiveKit itself can’t access media.
  • Global Scalability: Redis + Kubernetes allow for horizontal scaling across regions.
  • Bandwidth Optimisation: LiveKit dynamically adjusts media quality based on device and network conditions.
  • Adaptive Layers: For video resolution and bitrate to match various screen sizes and connectivity.
  • Stability Under Load: Real-time systems need to be reliable. LiveKit supports thousands of concurrent users with minimal latency and consistent quality.

AI-Powered Real-Time Applications

One of LiveKit’s unique strengths is its support for real-time AI use cases. Developers can route media streams directly into AI engines for processing and feedback.

Popular AI integrations include:

Advertisement
  • Live transcription using Whisper, Google Cloud Speech, or Deep gram
  • Real-time translation and captioning for multilingual audiences
  • Voice-based commands and virtual assistants
  • AI tutors and agents in educational or enterprise platforms
  • Emotion detection and intent classification in support calls
  • Call summarisation and analytics for sales or support.

These features allow you to create smarter, more responsive real-time applications.

Use Cases Across Industries


LiveKit is versatile and can be used in nearly any vertical. Common use cases include:

  • Education: Virtual classrooms, language learning apps, breakout rooms
  • Healthcare: Telehealth consultations, remote diagnostics, patient engagement tools
  • Gaming: In-game team chat, spatial audio, live streams
  • Enterprise: Internal communication tools, secure video conferencing
  • Media & Events: Live webinars, conferences, hybrid events
  • Customer Support: AI-assisted video support desks with chat and analytics

Because LiveKit is fully customizable and open-source, developers can adapt it to match specific workflows, branding, or compliance frameworks.

Why Developers Choose LiveKit


Compared to other real-time video platforms, LiveKit offers:

  • Open Source Freedom: No lock-in, transparent development
  • Extensive SDK Support: Develop once, deploy anywhere
  • Customisable Infrastructure: Tailor the experience end-to-end
  • Self-Hosting Options: For privacy and control
  • Ready for AI: Integrate voice, vision, and NLP models natively
  • Active Developer Community: Ongoing improvements, documentation, and support

Whether you’re building an internal collaboration suite or a consumer-facing live streaming platform, LiveKit gives you the tools and flexibility needed to deliver a standout experience.


Pricing and Plans


LiveKit offers a

tiered pricing model to support projects at every stage:

  • Free Tier: Up to 100 participants, 5,000 connection minutes, 50 GB bandwidth
  • Ship Plan ($50/month): For growing apps with 150,000 minutes and more bandwidth
  • Scale Plan ($500/month): Suitable for production apps and large user bases
  • Enterprise Plan: Custom support, SLAs, dedicated infrastructure

You can also self-host LiveKit for free, which is ideal for teams that prefer full control.

Billionaire Adam Weitsman Buys Fire Ghost NFT From Ghost Labs

Billionaire scrap-metal entrepreneur Adam Weitsman continues expanding his involvement in the non-fungible token space through high-volume acquisitions and intellectual property takeovers. In yet another bullish move, the scrap metal mogul has acquired a rare non-fungible token series from the digital asset incubation studio Ghost Labs.

Billionaire Adam Buys More NFTs

In a January 21 blog post, Billionaire Adam Weitsman confirmed he has bought a rare Fire Ghost NFT collection. “The non-fungible token market was pretty brutal today, so I thought I would help by supporting another NFT project that deserves a little more attention in my opinion,” Mr Adam wrote. The billionaire investor has bought 1/1 ‘Fire Ghost’ NFT from the digital asset incubation studio Ghost Labs.

Billionaire Adam Weitsman is a renowned industrialist, entrepreneur, investor, philanthropist, and crypto investor. Most recent estimates from his business and entertainment finance outlets place Adam Weitsman’s net worth in a broad range of about $1.2 billion to $1.5 billion, with some outliers reporting lower or higher figures. Adam serves as CEO of “Weitsman Recycling,” which has become the largest privately held scrap metal recycling company on the East Coast.

Scrap Meta mogul Adam Weitsman officially entered the NFT market in early 2023, marked by a high-profile $1.6 million purchase. Adam has substantially increased his NFT holdings by acquiring 5,000 Otherside NFTs, including Otherdeeds and Kodas, directly from Yuga Labs to support their metaverse project and 229 Meebits in an over-the-counter deal. He is also actively managing the HV-MTL project’s intellectual property. Last week, Adam purchased 100 Quirkies in a private transaction.

Billionaire Adam’s Motive for Buying NFTs

Unlike many traders in the NFT space, Adam Weitsman isn’t motivated by flipping or profit. He’s never sold an NFT in his life, and says he doesn’t believe in selling and never will. In the past pressers, Weitsman emphasized that his acquisitions are about “legacy, not liquidity,” prioritizing the preservation of digital culture over short-term financial gains. “I collect because I love the art, the people, and the history being made. For me, collecting is about legacy, not liquidity,” He said.

Polymarket to open free grocery store in New York City

Published

on

Polymarket launches on Solana through Jupiter integration

Polymarket is taking its brand offline, opening a free grocery store in New York City and backing it with a $1 million donation to fight food insecurity.

Summary

  • Polymarket will open a free grocery store in NYC on Feb. 12, open to all residents.
  • The company donated $1 million to Food Bank For New York City.
  • The move blends community support with a high-profile brand push.

Polymarket, the crypto-based prediction market platform, announced on Feb. 3 that it will open New York City’s first free grocery store later this month as part of a community-focused initiative.

The pop-up store, called “The Polymarket,” is set to open on Feb. 12 at noon ET and will offer groceries at no cost to visitors. The company said no purchase will be required, and the store will be open to all New Yorkers. Polymarket has not yet disclosed the exact location.

Alongside the launch, Polymarket donated $1 million to Food Bank For New York City, a non-profit that supports hunger relief across all five boroughs. The company described the donation as part of its effort to give back to the city it calls home.

A physical bet on community impact

Polymarket framed the project as a “real, physical investment” in New York. The company said the store will be fully stocked and emphasized that the initiative is meant to address food insecurity rather than function as a traditional retail operation.

Food Bank For New York City said the donation will support its ongoing work to expand access to food and strengthen long-term food security. Polymarket encouraged members of the public to contribute to the organization as well.

Sources familiar with the project say the grocery store is expected to run for a limited time, likely spanning several days around the opening weekend.

Marketing push amid rising competition

The move also comes as competition heats up among U.S.-based prediction market platforms. Rival Kalshi earlier staged a smaller free grocery giveaway in New York, prompting comparisons between the two campaigns.

Both efforts echo campaign rhetoric from New York Mayor Zohran Mamdani, who previously floated the idea of city-run grocery stores. Polymarket currently hosts active markets tied to whether such stores will open in the city by mid-2026, adding another layer of symbolism to the initiative.

The launch follows a busy stretch for Polymarket. In late January, the platform announced a multi-year partnership with Major League Soccer, becoming the league’s official prediction market partner. On Feb. 2, Polymarket integrated with decentralized exchange aggregator Jupiter, allowing users to access markets directly on Solana.

The company is also navigating regulatory pressure. A Nevada state court issued a temporary restraining order last week preventing Polymarket’s U.S. affiliate from offering certain contracts to Nevada residents, with a hearing scheduled for Feb. 11.

ETF that feasts on carnage in MSTR hits record high

ETF that feasts on carnage in MSTR hits record high

There’s always a bull market somewhere.

While bitcoin and shares of bitcoin holder Strategy are falling, an exchange-traded fund designed to move in the opposite direction of MSTR and double its daily change has hit a record high.

That exchange-traded fund is the GraniteShares 2x Short MSTR Daily ETF, trading under the ticker MSDD on Nasdaq. It is an actively managed fund designed to deliver -200% of the Strategy’s daily performance. In simple terms, if MSTR falls 2% in a day, the ETF targets a 4% gain that same day (before fees/decay).

The fund debuted on Jan. 10, 2025 and is seen as a high-risk short-term tactical tool for bears betting against MSTR. And it has lived up to its repute.

MSDD’s price hit a record high of $114 on Tuesday, up 13.5% on the year, extending the past year’s 275% surge, according to data source TradingView.

MSDD’s compatriot, the Defiance Daily Target 2x Short MSTR ETF (SMST), also clocked an 11-month high of $113 on Tuesday. This fund debuted on Nasdaq in August 2024.

In other words, MSTR bears out there who loaded up on these ETFs have made a killing.

Strategy fell to $126 on Tuesday, the lowest since September 2024, extending its multi-month bear market. The stock is now down a staggering 76% from its lifetime high of $543 in November last year.

Strategy is the world’s largest publicly listed bitcoin holder, stashing 713,502 BTC ($54.24 billion) at press time. Naturally, its share price tends to follow swings in bitcoin’s market value.

Bitcoin, the leading cryptocurrency by market value, has dropped 12% this year and traded as low as $73,000 on Tuesday. That was the weakest since late 2024. Since then, prices have bounced back to $76,000, thanks to narrowly approved funding package that alleviated near-term U.S. shutdown risk and stabilized risk sentiment in financial markets.

Why Cardano Investors Are Moving Assets to Self-Custody Now

Published

on

ADA Price


“Currently, a 10 billion market cap, this thing is not even worth $1 billion,” one X user argued.

The latest cryptocurrency market crash was brutal, sending Cardano’s ADA to multi-month lows.

Some analysts believe the storm may not be over, warning the price could nosedive by as much as 75% in the short term.

The Bad Days for the Bulls Aren’t Over?

Several hours ago, ADA plunged to 0.27, the lowest level since August 2024. Currently, it trades at around $0.29 (per CoinGecko’s data), representing a 15% decline on a weekly scale.

The well-known analyst DrBullZeus claimed that the asset is now nearing “a must hold support zone” at the range of $0.24-$0.28. He thinks that breaking below that level could result in a price crash to $0.125 and even $0.075.

The popular trader Matthew Dixon also chipped in. He suggested that “technically speaking,” ADA has retraced in three waves since the local top seen towards the end of 2024. He outlined $0.24 as a “very important long-term support,” predicting that as long as it holds, the price could rebound.

“A break of support would be a serious concern,” he alerted.

Prior to that, Harmonic Trader predicted that in six months, ADA might trade under $0.10. “Currently, a 10 billion market cap, this thing is not even worth $1 billion,” they argued.

Time to Rally?

Despite ADA’s recent price decline, some other analysts remain optimistic that a resurgence could be on the way. One of them, using the X nickname “Lucky,” asked their almost two million followers whether they plan to increase their exposure to the token at current rates. The analyst also envisioned a potential pump to nearly $1 in the near future.

LaPetite is also bullish. Several days ago, he forecasted that ADA is about to go “parabolic,” claiming that “huge announcements” concerning Cardano are coming soon.

The recent exchange netflows signal that a rebound could indeed be on the horizon. Data provided by CoinGlass shows that over the past days and weeks, outflows have significantly outpaced inflows. This means investors have been shifting from centralized platforms to self-custody, which in turn reduces immediate selling pressure.

Aave Shutters Avara Brand and Family Crypto Wallet

Published

Aave Shutters Avara Brand and Family Crypto Wallet

Aave Labs says it is sunsetting its “umbrella brand” Avara in the company’s latest move to refocus on decentralized finance and simplify its branding.

Aave founder and CEO Stani Kulechov posted to X on Tuesday that Avara, a company encompassing projects including the Family crypto wallet and previously the social media platform Lens, “is no longer required as we go all in on bringing Aave to the masses.”

Kulechov said the Apple iOS-based Family crypto wallet was also being wound down as the team has “learned that onboarding millions of users requires purpose-built experiences, such as savings, rather than generic, open-ended wallet experiences.”

The move marks Aave’s latest effort to refocus on products such as its flagship lending protocol as the project handed stewardship of Lens to the Mask Network last month, with Kulechov saying Aave’s role in the protocol would be reduced to an advisory role so it can focus on DeFi.

Kulechov said in his latest post that Aave was “now united as one team of world-class designers, engineers, and smart contract experts, aligned around a single mission: bringing DeFi to everyone.”

All future projects under Aave Labs

Avara said in a blog post that “all current and future products, including the Aave App, Aave Pro, and Aave Kit, will operate under Aave Labs” to simplify the brand.

It added that accounts linked to the Family wallets “will continue as core infrastructure within Aave Labs products,” but the iOS app would be wound down over the next year.

No new users will be onboarded to the app from April 1, and existing users can continue using the app until April 1, 2027, and will continue to have full access to their funds on Aave’s website.

Aave is the biggest DeFi protocol with $30 billion in total value locked, nearly $9 billion more than the next largest project, the staking protocol Lido, which has $21.7 billion in value locked, according to DefiLlama.
