    I really want to sign up for Beeper, but the fact I have to give them my phone number to sign up for a waitlist seemed like a red flag. How is their security profile?

      Notice how in the article they say “we’re not the middle man… Any more”? That’s because, up until now, Beeper has been working on a system where they operate as a middle man for your data.

      But to be fully trusted, Beeper Mini will need to be audited by a third party — something it has not yet done. In addition, Beeper uses certificate pinning, which makes network traffic analysis more difficult to perform in order to verify its claims.

      And until they release the source code for their new app, something they probably don’t have a huge incentive to do (it would open them up to competition, or people who don’t need to charge you a $2/mo subscription for something that has nothing to do with their servers) there’s basically nothing guaranteeing their product is secure, or private.

        By that logic, there’s nothing guaranteeing iMessage on iPhones is secure or private either because it’s closed source. If you don’t want to trust Beeper mini, you’ll be free to run their iMessage bridge on your own Matrix stack when they open source it at some point, which they’re promising to do (and you still won’t know that Apple isn’t scraping your messages on the iOS side). When I decide to trust a company, it’s because I look at what they’re transparently communicating to their end users. Every indication is that they are trying to get out of the middle of handling encrypted messages. Their first move to make this happen was allowing people to self host their own Beeper bridges (which you can still do with Beeper Cloud if you prefer and you will know that your messages are always encrypted within the Beeper infrastructure). They aren’t going to release the source for their client ever because that’s the only way they make any money.

          I tend to trust actual open source projects over closed-source ones. Beeper Mini is closed source. And Beeper is a separate app not really relevant to this discussion.

        They do have to run servers in order to keep the service alive. If you want to run this stuff yourself on your own server that’s possible using PyPush. The reason they have to run those servers for you is to keep the notification service alive.

          Can you cite your sources? You appear to have confused Beeper Mini with Beeper…

          1. Mini only needs optional push servers to run.
          2. There’s no Beeper Mini source code
          3. You have to log in to Beeper Mini exclusively using a Google account

            Yeah, sorry, I got confused. Beeper mini does need servers to keep the notification service alive. And thus not crazy to ask for 2$ a month. Beeper cloud could indeed do without servers I guess, but I don’t know anything about that. I was just keeping up with the development of pypush (the python poc) and reverse engineering progress.

            I don’t understand your point of “you have to log in with a google account”. I understood that was a requirement to check subscription status (and as such limit fraudulent apk’s).

            But that seems to be a different story than “opensourcing this would mean a competitor could do it for free”.

            You can already do this for free with pypush. And if you want to use something else then python you could build something based on it with any language as pypush is completely open source.

        Notice how in the article they say “we’re not the middle man… Any more”? That’s because, up until now, Beeper has been working on a system where they operate as a middle man for your data.

        To be fair they never claimed otherwise and all of the code for the bridges are open-sourced and can be run on your own servers so that those servers you control (as opposed to Beeper-owned servers) act as a “middle man” and none of your messages need be trusted to a 3rd party.

        To put it simply: only the actual bridge on Beeper Cloud has access to unencrypted messages and you do have the option to run the bridge yourself while continuing to use the Beeper app. You can use as many or as few self-hosted bridges as you’d like.

        A few bridges are preconfigured for self-hosting with just a couple of clicks for free through fly.io here

      That’s to prevent multiple entries by one person. Their security is very good, with audits and their products being largely open source (for this, PyPush. For Beeper Cloud, their Synapse fork and their bridges.). Only the parts that don’t matter to security (the clients, mostly) are closed source.

        Btw will they continue to live as Element changed licences to Synapse and Dendrite projects ?

          Yes. They have a fork of Synapse that they can continue to use even if the license prevents them from using upstream (which doesn’t seem true, but I could be wrong).

      This post is referring to beeper mini. It’s confusing naming, but that’s not the same as beeper(cloud service). Beeper mini is available to everyone on the play store and is not a cloud service. You just get it, login to Google (to pay the subscription cost) and it works. No invite needed
