Mark Zuckerberg has built Meta into one of the most powerful technology companies on earth — and a significant part of that story involves copying what competitors were doing well, and doing it at a much larger scale. Some of these bets paid off spectacularly. Others were dead on arrival. Either way, the pattern is impossible to ignore.
Here’s a look at every major product or feature Meta has cloned over the years, how it played out, and where things stand now.
1. Instagram Stories (2016) — Copied from Snapchat
Snapchat invented the disappearing stories format, and for a while it seemed like the kind of product that could pull younger users away from Facebook permanently. Snapchat’s daily active user numbers were rising sharply, and the format — casual, ephemeral, no pressure — was genuinely different from how Instagram or Facebook felt. When Zuckerberg tried to acquire Snapchat for $3 billion in 2013 and was turned down, he took note.
Instagram launched Stories in August 2016, and it was so obviously modeled on Snapchat that even the feature name was borrowed wholesale. Instagram’s version had the same 24-hour disappearing format, the same vertical tap-through navigation, and the same dual-camera option. Snapchat’s CEO Evan Spiegel publicly called out the copying, but the numbers told the real story. Instagram Stories reached 100 million daily active users within two months of launch. By 2018, Instagram Stories had more daily users than Snapchat’s entire platform. For Snapchat, the launch of Instagram Stories marks the moment its growth trajectory was permanently interrupted.
2. Facebook Marketplace (2016) — Copied from Craigslist and eBay
Facebook launched Marketplace in October 2016 as a peer-to-peer buying and selling platform, taking direct aim at Craigslist and, to a lesser extent, eBay. The idea was straightforward: Facebook already had the social graph, the trust layer, and the mobile audience. All it needed to do was give people a tab to buy and sell things.
Early coverage largely dismissed Marketplace as a pale imitation of Craigslist, which had dominated classifieds since the internet was young. Craigslist’s hold on the space had already survived multiple competitors. But Facebook’s distribution advantage was too large to ignore, and by 2018, Marketplace had more than 800 million monthly users — a figure that dwarfed Craigslist’s total traffic. As of 2025, Marketplace reportedly had 1.2 billion users, roughly 40% of Facebook’s total monthly active users. Craigslist still exists, but it’s no longer the default for most people looking to buy or sell secondhand goods.
3. Instagram and Facebook Reels (2020) — Copied from TikTok
TikTok changed the logic of social media. The algorithm-first, short-form video feed — optimized to show users content from creators they’d never followed — was genuinely new, and younger users flocked to it. For Meta, TikTok was a threat of a different kind: it wasn’t just competing for time, it was competing for an entire generation’s primary social media habits.
Instagram launched Reels in August 2020, and Facebook followed. The format was essentially TikTok’s — short vertical video, algorithmic recommendation, a dedicated feed. The reception was cold initially; many creators openly preferred TikTok’s native editing tools and audience. But Meta leaned in hard, paying bonuses to creators who posted on Reels and giving Reels premium placement in feeds. Over time, Reels became a genuine engagement driver. By 2023, Reels was one of Meta’s fastest-growing revenue contributors, with advertisers following creator attention into the format. TikTok still exists and remains dominant with certain demographics, but the existential threat it once posed to Meta’s core platforms never fully materialized.
4. Messenger Rooms (2020) — Copied from Zoom and Houseparty
The pandemic made video calling essential overnight, and Zoom became a household name in weeks. Houseparty, a drop-in video chat app with a social discovery angle, was also surging. Facebook launched Messenger Rooms in April 2020, positioning it as a socially-oriented alternative that could support up to 50 participants at once with no time limits.
The pitch had something going for it: Rooms were accessible without a separate app download, worked across Facebook’s ecosystem, and had a lower bar for casual use than Zoom. But Messenger Rooms never found a real foothold. Zoom had locked in enterprise and education users with features that actually mattered in those contexts — screen sharing, breakout rooms, calendar integrations. Rooms was social by design and thin on professional utility. As pandemic-era behavior normalized, Messenger Rooms quietly faded from view, more of a checkbox entry in Meta’s product history than a product anyone uses today.
5. Libra / Diem (2020) — Copied from Crypto Stablecoins
In 2019, Meta announced Libra — an ambitious proposal to launch a global stablecoin backed by a basket of fiat currencies, managed by a consortium including Visa, Mastercard, PayPal, Uber, and others. The idea was to build a payment layer for the billions of people on Facebook and WhatsApp, particularly those without access to traditional banking. It was framed as financial inclusion, but regulators saw it differently.
The backlash was almost immediate. Central bankers in the US and Europe treated Libra as a direct challenge to monetary sovereignty. Congressional hearings were hostile. Partners including PayPal, Mastercard, and Visa withdrew. By December 2020, Libra had been rebranded as Diem and scaled down from a multi-currency basket to a single US dollar-backed stablecoin. It didn’t help. In January 2022, Meta wound down the project entirely, selling Diem’s assets to Silvergate Bank for around $200 million. Former Diem co-creator David Marcus later described the project’s death as a “political kill.” The technology lived on through the people who built it — alumni went on to found the Aptos and Sui blockchains — but Meta itself walked away with nothing. Meta is now exploring stablecoins again, this time via USDC payments for creators, under more favorable regulatory conditions.
6. Live Audio Rooms (2021) — Copied from Clubhouse
Clubhouse arrived during the pandemic as something genuinely novel — audio-only, drop-in conversations with anyone from Elon Musk to venture capitalists discussing startup strategy. It was invite-only, iOS-only, and extremely buzzy in tech circles during early 2021. Zuckerberg himself appeared on Clubhouse multiple times and praised the format.
Facebook launched Live Audio Rooms in June 2021, with a near-identical format: a host stage up top, listeners below, a hand-raise mechanism to become a speaker, and no limit on the number of listeners. The product also supported up to 50 speakers simultaneously, one-upping Clubhouse’s more restrictive room architecture. What Meta couldn’t replicate was the timing. By the time Live Audio Rooms launched globally, pandemic lockdowns were easing and the curiosity that had driven Clubhouse’s rise was cooling fast. Clubhouse download numbers had already begun falling sharply. Meta shut down its audio and podcast services in June 2022, folding Live Audio Rooms back into Facebook Live.
7. Metaverse + Rebrand to Meta (2021) — Inspired by Decentraland and The Sandbox
In October 2021, Facebook rebranded to Meta and announced it would spend tens of billions building the metaverse. The concept — a persistent, immersive virtual world where people could work, socialize, and play as avatars — had been explored in tech and crypto circles for years. Decentraland and The Sandbox were already building blockchain-based virtual worlds with digital land ownership, virtual economies, and creator marketplaces before Meta made the concept mainstream.
Meta’s metaverse bet was distinct in that it leaned on VR hardware through its Quest headsets and centralized infrastructure, rather than blockchain. Horizon Worlds, the flagship virtual world, attracted somewhere around 200,000 monthly active users a year after launch — a number that, by any measure, didn’t justify the ambition. Reality Labs, the division responsible for the metaverse push, had accumulated operating losses of roughly $80 billion by 2025. Meta eventually scaled back Horizon Worlds’ VR version and redirected resources toward AI and smart glasses. The rebrand stuck; the metaverse vision, as originally articulated, did not.
8. Bulletin (2021) — Copied from Substack
Newsletters had their moment. Substack emerged as the platform where journalists, writers, and thinkers could build direct relationships with readers through paid subscriptions, without relying on algorithmic amplification. Meta launched Bulletin in July 2021 to compete for that audience.
Bulletin offered writers their own branded page, subscription tools, and access to Facebook News distribution. The company signed prominent names including Malcolm Gladwell, Malala Yousafzai, and Tan France. Zuckerberg described it as the first time Meta had built something specifically for journalists and writers. Bulletin’s core problem was structural: the Facebook audience and the Substack audience didn’t overlap in the way Meta hoped. Substack’s appeal was about independence and direct reader relationships — exactly the things that felt absent from a product built inside a Facebook tab. Meta shut Bulletin down in October 2022, about 18 months after launch. It went fully offline in April 2023.
9. Instagram “Candid Stories” (2022) — Copied from BeReal
BeReal was the anti-Instagram — a French app that sent users a daily notification to post an unfiltered photo using both cameras simultaneously. You couldn’t edit, filter, or schedule it. The point was authenticity, and it won Apple’s iPhone App of the Year award in 2022 with 53 million downloads.
Instagram launched Candid Stories in December 2022, replicating BeReal’s core mechanic almost exactly: a daily notification, simultaneous front-and-back camera capture, and posts visible only to friends who had also shared their own Candid. The irony of Instagram — arguably the platform most associated with curated, filtered, aspirational content — launching an authenticity product was not lost on observers. The feature was tested initially in South Africa. BeReal was acquired by French gaming company Voodoo in 2024, and while it survived, it never grew into a platform of meaningful scale. Candid Stories quietly faded as well.
10. Threads (2023) — Copied from Twitter / X
When Elon Musk acquired Twitter in late 2022 and began making sweeping changes — mass layoffs, controversial product decisions, verification chaos — there was a window that Meta moved through quickly. Threads launched in July 2023 as an Instagram-linked, text-based social network that was structurally almost identical to Twitter: chronological and algorithmic feeds, following-based discovery, short text posts, and a public conversation format.
The launch was, by any measure, a success in terms of early numbers. Threads hit 100 million sign-ups in five days, aided enormously by the fact that Instagram users could port their following graph over instantly. Whether those sign-up numbers translated to genuine, sustained engagement was debated for months afterward. By 2026, Threads had integrated with Mastodon’s ActivityPub protocol and was cross-posting with Instagram Stories, positioning itself as a long-term platform rather than a protest sign-up. Whether it can hold its own against X remains genuinely open.
11. LLaMA (2023) — Copied from ChatGPT
ChatGPT’s launch in November 2022 caught the industry off guard. Meta had been doing AI research for years — its Fundamental AI Research team, headed by Yann LeCun, had done serious academic work — but it had no consumer AI product to speak of. Meta released LLaMA in February 2023, an open-source family of large language models positioned as a research alternative to GPT. Unlike ChatGPT, which was a closed consumer product, LLaMA was released for researchers and later, more broadly, for commercial use.
The open-source angle gave LLaMA genuine traction in the developer community. Successive versions — Llama 2, Llama 3 — were considered competitive. The story took a difficult turn with Llama 4, which Meta released in April 2025 with strong benchmark claims. Those claims turned out to be benchmarks that had been “fudged a little bit,” as LeCun himself later confirmed — the company had submitted fine-tuned models for evaluation while releasing different versions to the public. The fallout was significant. Zuckerberg sidelined the entire GenAI organization, LeCun departed, and Meta overhauled its AI operations entirely. As of mid-2026, Meta has relaunched its AI efforts under a newly formed Superintelligence Lab.
12, Arena (2026) — Copying Polymarket
Prediction markets had their mainstream moment. Platforms like Polymarket and Kalshi, where users can bet on outcomes from elections to sports results to economic data, saw combined monthly trading volumes reach $24 billion in April 2026. The numbers were impossible to ignore.
According to a New York Times report published in June 2026, Zuckerberg has tasked a small internal team with building a standalone prediction app, internally called Arena. Unlike Polymarket, which runs on crypto rails, Arena is being designed around a points-based system rather than real-money wagering — at least initially. That sidesteps the regulatory complexity that has created friction for crypto-based prediction markets. Meta plans to use its combined daily active user base of 3.56 billion people across Facebook, Instagram, WhatsApp, and Threads to seed Arena’s audience, separate from those platforms but fed by them. Whether Arena ever launches publicly, and whether Meta’s track record with standalone apps gives reason for optimism, is another question. The company’s history with products outside its core social graph is, at best, uneven.
Meta’s playbook is consistent enough by now that it barely requires explanation. Find a product gaining traction. Build something similar at scale. Use the distribution of billions of existing users to either absorb the competitor or contain them. When it works — Stories, Reels, Marketplace — the results are significant. When it doesn’t — Messenger Rooms, Bulletin, the metaverse — the losses are written off and the company moves on. Arena will be the next test of whether that approach still has legs in a space where distribution alone may not be enough.
