Is OpenDescent a good Telegram alternative?

It depends on what you use Telegram for. If you want private one-to-one and group messaging that is end-to-end encrypted by default, with no phone number and no central server, OpenDescent is built for exactly that. If you mainly use Telegram for huge public channels, large communities and bots, Telegram is genuinely strong there and OpenDescent is not trying to replace it. OpenDescent is also currently Windows-first, with macOS, Linux and mobile in progress.

Comparison / OpenDescent vs Telegram Published 2026-06-24

The Telegram alternative that's private by default.

Q: Do I need a phone number to use Telegram?

Yes. Telegram requires a phone number to register an account, which ties your identity to a government-issued identifier. OpenDescent works differently: your identity is a cryptographic keypair, not a phone number or account. There is nothing to register, no phone number to hand over, and no central directory linking your conversations to your legal identity.

Q: Why use a private Telegram alternative if Telegram already encrypts chats?

Encrypted in transit and at rest is not the same as end-to-end encrypted. Telegram's default cloud chats are stored on Telegram's servers in a form the platform can in principle read, and they are tied to your phone number. A peer-to-peer messenger that is end-to-end encrypted by default removes the central server, the account requirement and the phone number in one go, so privacy is a property of the architecture rather than a setting you have to remember to switch on.

Telegram is fast, polished and genuinely brilliant for big public channels and communities. We're not here to argue otherwise. But there's one thing a lot of people get wrong about it: ordinary Telegram chats are not end-to-end encrypted. Only its one-to-one Secret Chats are, and almost nobody uses them. OpenDescent takes the opposite default: every conversation, including groups, is end-to-end encrypted, with no phone number and no central server holding your messages.

Short version

Telegram is excellent at what it's known for: large public channels, big communities, broadcasts and bots. We're genuinely not trying to replace that, and OpenDescent isn't built for it.
The thing most people miss: ordinary Telegram chats are not end-to-end encrypted. They're encrypted in transit and at rest on Telegram's servers, but the platform can in principle read them.
Telegram's end-to-end encryption only lives in Secret Chats, which are one-to-one and not the default. Group chats are never E2E.
OpenDescent flips the default: every conversation is end-to-end encrypted, with no phone number and no central server. Your identity is a key you hold, not a profile in a directory.

§ 02 / Defaults

Telegram talks about encryption a lot, and it isn't lying. The subtlety is in which kind. Telegram has two sorts of chats, and they protect you very differently. The one almost everyone uses is the weaker of the two.

Cloud chats

The default

Not end-to-end

Group chats

All of them

Never E2E

Secret Chats

Opt-in · 1-to-1

End-to-end

Telegram's default cloud chats are encrypted in transit and stored encrypted on Telegram's servers, but Telegram holds the keys, so in principle the platform can read them. End-to-end encryption only applies to Secret Chats, which are one-to-one and off by default. Group chats are never end-to-end encrypted.

Why "encrypted" can be misleading

It's easy to see the word "encrypted" and assume nobody but the people in the chat can read it. With Telegram's default chats, that isn't quite the deal. Three things sit outside the protection most people imagine they have:

Your default chats live on Telegram's servers. Cloud chats are convenient because they sync across every device, but that convenience exists precisely because Telegram stores them centrally, in a form its infrastructure can in principle access.
Group chats are never end-to-end encrypted. Secret Chats, Telegram's only E2E option, are strictly one-to-one. The moment a conversation involves three people, end-to-end encryption is off the table on Telegram.
You handed over a phone number. Telegram requires one to register, which ties your account to a government-issued identifier and a central directory, whether or not you ever turn on a Secret Chat.

▶ The structural point

"Encrypted in transit and at rest" means the company can still read your messages if it chooses to or is compelled to. "End-to-end encrypted" means it can't. OpenDescent makes the second one the default for every chat, including groups, and removes the server that would hold them in the first place.

To be clear, none of this makes Telegram a bad app. It makes it a different kind of app from a private messenger. If you want a closer look at how OpenDescent's encryption and identity model work, the security page walks through it, and the features page covers what the app actually does.

When Telegram is the better choice today.

§ 03 / Honest

We'd rather you make an informed choice than a loyal one, and there are plenty of situations where Telegram is the right tool. Pretending otherwise would be daft, because Telegram is very good at things OpenDescent isn't built to do.

You're running a large public channel or community. Broadcasting to thousands or hundreds of thousands of people, with public discovery and search, is exactly what Telegram is built for. OpenDescent is a private messenger, not a broadcast platform, and it isn't trying to be one.
You need it on your phone first. Telegram is mobile-first and runs beautifully on iOS and Android. OpenDescent is currently Windows-first, with macOS, Linux and mobile in progress, so if your messaging mainly happens on a phone, Telegram covers that today.
You rely on bots and the wider ecosystem. Telegram has a large, established bot platform and a deep set of integrations. If your workflow depends on those, a standalone private messenger won't replicate them.

None of that is a knock on OpenDescent; it's simply where each tool sits right now. Our pitch is narrower and honest: for the one-to-one and group conversations where you'd rather no company could read them, there is now an option that is private by default. You don't have to delete Telegram to keep a few conversations somewhere quieter.

▶ Our position

Use the right tool for the job. Keep Telegram for the channels, communities and broadcasts it does so well. Move the private conversations, where end-to-end encryption actually matters, to something with no company in the middle.

Questions, straight answers.

§ 04 / FAQ

Is Telegram end-to-end encrypted?01

Not by default. Telegram's ordinary chats, which it calls cloud chats, are encrypted in transit and at rest on Telegram's servers, but they are not end-to-end encrypted, so the platform can in principle access their contents. Telegram does offer Secret Chats, which are end-to-end encrypted, but those are one-to-one only and off by default. The chats most people use every day are not E2E.

Are Telegram group chats encrypted end-to-end?02

No. Telegram's end-to-end encrypted Secret Chats are for one-to-one conversations only. Group chats, channels and the cloud-synced chats most people use are not end-to-end encrypted. They are stored encrypted on Telegram's servers, but Telegram holds the keys. OpenDescent encrypts every conversation, including groups, end-to-end by default. See how that works.

Do I need a phone number to use Telegram?03

Yes. Telegram requires a phone number to register, which ties your account to a government-issued identifier and a central directory. OpenDescent works the other way round: your identity is a cryptographic keypair, not a phone number or account. There is nothing to register, no phone number to hand over, and no directory linking your conversations to your legal identity.

Why use a private Telegram alternative if Telegram already encrypts chats?04

Because encrypted in transit and at rest is not the same as end-to-end encrypted. Telegram's default cloud chats are stored on its servers in a form the platform can in principle read, and they are tied to your phone number. A peer-to-peer messenger that is end-to-end encrypted by default removes the central server, the account and the phone number together, so privacy is a property of the architecture rather than a setting you have to remember to switch on.

Is OpenDescent's encryption better than Telegram's?05

The honest comparison is about defaults, not just algorithms. OpenDescent end-to-end encrypts every chat, including groups, by default, using ephemeral X25519 key agreement per message for forward secrecy, AES-256-GCM for content and Ed25519 for signatures. Telegram only end-to-end encrypts one-to-one Secret Chats. OpenDescent is fully open source under the MIT license, so you can read and run it yourself. The caveat: it hasn't been through a formal professional audit yet, and its user base is far smaller than Telegram's.

Should I stop using Telegram for everything?06

No, and we wouldn't suggest it. Telegram is genuinely strong for large public channels, big communities and bots, and OpenDescent isn't trying to replace that. The sensible split is to keep Telegram for the public, broadcast side of things, and move the private one-to-one and group conversations, where end-to-end encryption matters, to something built for privacy by default.
