fisfis vs NGL — a straight comparison of two anonymous inboxes
Both give you a link to put in a bio. What happens after somebody writes to it is where the two stop resembling each other.
At a glance
Both hand you a link. Both let strangers write to you without a name. From there they diverge on four things, and the four are not equally important: cost decides whether you can read your messages at all, and everything else decides what the inbox is like to live with.
| NGL | fisfis | |
|---|---|---|
| Cost to receive messages | A paid tier exists and is promoted | No paid tier at all |
| Finding out who wrote | Was sold as a hint; the FTC's 2024 complaint said the hints did not reveal senders | Not offered, not sold, not planned |
| Replying to a message | Screenshot it to a story | A thread the sender can return to |
| Blocking one sender | Limited | One sender, without closing the inbox |
| Images from strangers | Not the focus of the product | Held until checked, then shown |
| Age | Order requires a neutral age gate barring under-18s | Intended for adults sharing a public link |
| Your address | A generated link | fisfis.cc followed by the name you claim |
What it costs
NGL operates a paid tier. The FTC and the Los Angeles District Attorney announced an action in July 2024 alleging, among other things, that users were pushed toward that tier believing it would reveal who had written and that it did not, and that many were charged a recurring weekly fee of up to $9.99 having thought they were paying once. It was settled by an order, and the settlement totalled $5 million.
fisfis has no paid tier. Not a cheaper one, not a fairer one — none. Claiming a name is free, the address is free, and every message that reaches your inbox is one you can open. There is no hint to buy because there is nothing to sell you.
Whether you can reply
This is the difference people underrate before they have used both, and the one they mention first afterwards.
An anonymous message is quite often a real question. Somebody has worked up to asking it and the answer matters to them. On a one-way inbox the only way to answer is to screenshot the message onto a story with your reply typed underneath — which broadcasts to everybody a thing that was sent to one person, and still relies on them happening to be watching.
On fisfis your reply waits on that thread link. They open it, read the answer, and can write again. The whole exchange stays private, and stays anonymous, which is the combination the screenshot workaround gives up on both counts.
What you can do about a bad message
Every anonymous inbox eventually receives something unpleasant. The question is not whether it happens — it is what you are holding when it does.
- Close the inbox. The page stops taking messages and your name stays yours. Reversible whenever you want.
- Block one sender. Just them. They keep seeing an ordinary send screen, so there is no moment where they discover the block and start over from a clean slate.
- Images wait. A picture is checked before you are shown it, so the first time you see one is a moment you chose.
- Word rules and rate limits run first. Before anything reaches you at all.
The longer version of this is its own post, because “is it safe” is really a question about which of these controls exist and who holds them.
Reach, apps and where it opens
Both are shared as a link, and neither asks the sender to install anything, which is the single most important thing a link in a bio can get right.
The difference is at your end. fisfis is a website first: your console opens in a browser, and can be installed to a phone’s home screen if you want it there. That is an option rather than the way in. It also means there is no app store listing to be available or unavailable in your country — it opens the same way anywhere a browser does, which for readers in Bangladesh, India and the rest of the Bengali-speaking world is the practical difference between a product existing and not.
Where NGL genuinely suits people better
Two honest cases, because a comparison with none is an advert.
Your whole group already uses it
Network effects are real and they are not defeated by a feature table. If everybody you would want to hear from already has the app open and knows what the link is, that is worth something a better inbox with nobody on it is not.
You want the game, not the conversation
The prompt-and-guess format — a question posted to a story, replies arriving as a stream, the fun of trying to work out who — is a genuine thing people enjoy, and it is what that style of app is built around. A threaded inbox is a different pastime. If you did not want a conversation, the ability to have one is not a benefit.
Which link to share
Share fisfis if you want to read everything that arrives without paying for the privilege, answer the people who wrote to you, and keep a set of controls that let you deal with one bad sender without ending the whole thing.
Stay where you are if your audience is already there and the guessing game is the point.
Claiming a name takes about a minute and costs nothing. If you are also weighing the letter-style apps, the other comparison is fisfis and Chithi.me.
Questions people ask
- What is the biggest difference between fisfis and NGL?
- Replies. On fisfis your answer waits on the thread link the sender already holds, so an anonymous message can become a conversation. An inbox built around a single incoming message ends where fisfis begins.
- Does fisfis charge to reveal who sent a message?
- No. Nothing on fisfis is sold, and identity is not a product held back for payment. The FTC's 2024 complaint against NGL Labs described paid hints that did not reveal a sender; fisfis has no equivalent because it has nothing to sell.
- Can I use fisfis on Instagram, TikTok or a group chat?
- Yes. Your address is a plain web link, so it goes wherever a link goes — a bio field, a story sticker, a pinned message in a group chat. Whoever opens it can write straight away.
- Is fisfis available in Bangladesh and elsewhere?
- Yes. It is a website rather than a regional app store listing, so it opens the same way anywhere a browser does. The name is the Bengali word for a whisper.
