In the summer of 2017, an obscure Saudi-built web tool called Sarahah became — for a few impossible weeks — the most-downloaded free app on both Apple's App Store and Google Play. By 2018 it was banned from both stores. By 2019 the founder had abandoned the project entirely. What happened in those eighteen months is the cautionary tale every anonymous-messaging product has been wrestling with ever since.
The improbable rise
Sarahah — the Arabic word for “honesty” — was built by Zain al-Abidin Tawfiq, a Saudi developer working alone. The original idea was modest: a tool for companies to collect anonymous feedback from employees. Public-facing pages weren't in the launch plan. They emerged accidentally when individual users started sharing their personal Sarahah links on social media, asking friends and followers to send them anonymous messages.
Then a feature change on Snapchat in mid-2017 turned this trickle into a flood. Snapchat had just added a paste-link sticker, and Sarahah links spread inside that sticker faster than anything the platform had seen. Within weeks, Sarahah had topped 300 million users — including the entire teenage population of multiple countries.
The collapse
Anonymous platforms at scale always face the same problem: the median message is fine, but the long tail of harassment is the part that gets covered in the press. Sarahah was no exception. By late 2017, articles were running about teenagers receiving cruel anonymous messages — including some tragic cases that, while it's never possible to prove direct causation, were associated with the app in public perception.
A petition asking Apple and Google to remove Sarahah collected 470,000 signatures. In February 2018, both stores quietly de-listed the app worldwide. The web version continued operating but lost most of its growth engine without app store distribution.
Tawfiq, who had been running the entire operation essentially as a solo developer with a small team, did not have the resources to build out the moderation infrastructure that a 300-million-user platform needs to operate safely. By late 2019, the app was effectively abandoned. The website still resolves today but is not actively maintained.
What we learned from the autopsy
Several years on, the design lessons from Sarahah have shaped every anonymous-messaging product since. Three stand out:
1) Anonymity without context is a recipe for cruelty
Sarahah's interface gave the recipient no context at all about the sender — not even a hash, not even a country, not even a sense of whether two messages came from the same person. This made messages feel disembodied. Disembodiment correlates with disinhibition, and disinhibition with cruelty.
Modern platforms balance this by providing the recipient with some sense of structure: which messages share an origin, which look automated, which are part of a broader pattern. The sender stays anonymous; the message gets contextualised.
2) Moderation is not optional at scale
Sarahah's team had no proactive content moderation in 2017. The app shipped with a passive “report” button and that was essentially it. At 300 million users, this approach produces thousands of harassment incidents per day that the platform never sees.
Every successor — NGL, Sarhny, Tellonym — has had to invest in automated abuse detection from day one, plus a human moderation team scaled to volume. This is the unglamorous infrastructure that the original Sarahah was built without, and it's the single biggest reason platforms shipped today look very different under the hood even when they look similar on the surface.
3) The business model determines the safety model
Sarahah had no business model. It was a free utility that the founder ran out of personal interest. This meant there was nobody to fund safety infrastructure even when it became clear it was needed.
The post-Sarahah generation of platforms has had to pick a side. Some, like NGL, leaned into a premium subscription that gave hints about message senders — a model the US Federal Trade Commission later said misrepresented what users actually got, fining the company $5 million in 2024. Others, like Sarhny, took the opposite path: explicit commitment to never selling sender hints under any price, with the platform funded by ads and a separate subscription for premium recipient features (better moderation tools, larger message archives, custom domains). The choice of who pays for what ends up determining what kind of platform you have.
Where users actually went
The post-Sarahah migration was messier than press coverage suggests. A few patterns:
- NGL captured the English-speaking teenage market.Its tight Instagram Stories integration replicated the original Snapchat virality. The trade-off was the premium-hints model that eventually drew regulatory attention.
- Curious Cat picked up the older, more text-heavy users.The platform's slower interface and longer answers made it less appealing to teens but very sticky for academics, writers, and a dedicated Spanish-speaking community.
- Tellonym took most of the German-speaking marketand a meaningful share of Eastern Europe, with stronger automated moderation than the alternatives.
- The Arabic-speaking market fragmented for years.A long line of small clones tried to recreate the original Sarahah (Sarahah Plus, Saraahah, sarhne, etc.), most of them poorly maintained. The market consolidated around purpose-built Arabic platforms only late in the 2020s, with Sarhny becoming the dominant honest-messaging platform for native Arabic speakers.
What this means if you're building one today
If you're a founder thinking about entering the anonymous-messaging space, the Sarahah arc is the syllabus. Six clear lessons:
- Plan moderation from day one, not as a v2 feature. The economics of a platform that goes viral without safety infrastructure don't work.
- Don't monetise sender identity. The temptation is real because users will pay. The regulatory consequences (and the long-term trust damage) make it a bad trade.
- Provide context to the recipient. Pattern detection, message clustering, automatic spam scoring — give recipients the information they need to triage what arrives.
- Localise honestly, don't just translate.Arabic users especially have stayed away from platforms that obviously bolted on RTL support late. Build the locale in from the schema layer.
- Have a deletion story. Users will leave. Make sure they can take their data out and erase what was about them.
- Decide your jurisdiction early. Where your servers are determines what governments can compel from you, and users should be able to know this before they sign up.
The bigger pattern
Anonymous communication is older than the internet — it's older than print. Roman bathhouse graffiti, Victorian poison-pen letters, the lost art of the anonymous newspaper letter to the editor — every generation has rediscovered both the value and the dangers of identity-free speech.
Sarahah wasn't the first generation to learn the lessons of anonymity-at-scale, and it won't be the last. But it was the first time the global teenage population learned the lessons in real time. The platforms that followed have had to engineer around the gap Sarahah left, and the products that survive long-term will be the ones that take all six lessons above seriously.

FAQ
Did Sarahah ever try to come back?
There was an unofficial “Sarahah Plus” relaunch attempt and a few clone projects, but the original founder publicly stepped away and the brand never officially returned to the app stores. Today, the original sarahah.com still resolves but is not actively maintained.
Why did Apple and Google delist Sarahah but not similar apps?
Sarahah was the first anonymous app at that scale to attract coordinated public pressure (the 470k-signature petition was unusually large for an app removal request). Subsequent platforms learned from this and shipped with safety features that made removal pressure harder to organise.
Is anonymous messaging fundamentally unsafe?
No. The format is fine; the implementation determines outcomes. Email is anonymous if you use a fake address; comment sections are anonymous if you use a fake handle; the Bible has anonymous scripture. The question isn't whether anonymity is bad, but whether the platform around the anonymous channel does enough to keep its average user safe.
What's the biggest difference between Sarahah in 2017 and Sarhny today?
Three things: live abuse detection that flags malicious patterns before recipients ever see them, opt-in controls that let users scope who can message them (anyone / followers only / disabled), and a non-anonymous public-feed surface (the “Shahed” feed) that gives the platform a healthy growth engine independent of the anonymous-message channel.
