Ask HN: Why is there no enterprise grade open-source zoom alternative?
We have a client who are looking to replace zoom in their org. They like to self-host everything, and are wary of using outside services. We help them run their own email, and over the years we have helped them set up GitLab and Mattermost, etc which they are happy enough with.
We've set up a Jitsi installation but our stakeholders are wary about the limits on number of participants -- they can't really do department meetings or let alone an all-hands type of meeting with ~1000 people on the call. Also, some parts of their org are invested in the zoom usage/meeting stats too, and so that is another piece we'd have to figure out. We've also had mixed results testing with team members far away on rough connections, where audio/video was workable in zoom but sometimes unworkable with our internal setup.
Has anyone scaled up to 1000 and beyond with any open source solution? Any stories of success or failure? Are there other options to consider than Jitsi? Why is there no one crushing it like GitLab or Mattermost in this space?
- PaulHoule 4y agoI'd point to this related question. "Chat" services of various kinds have been around on the internet since the 1990s, the one thing that they all have in common is that they burn out. For instance there was CUSeeMe, Paltalk, Tivejo, AOL Instant Messenger, ICQ, Skype, WebEx, Facebook Messenger, and many others. Google alone has made 11. Some of them are still around, but there's a general pattern that a company does the work to create an application but doesn't do the work to keep it up. Then some new thing comes along, gets popular for a while, then deteriorates. Unless Zoom breaks the pattern a few years from now there will be something new and people will be saying "It's like the way Zoom used to be back when Zoom worked". I'd say open source alternatives would run into the same problem as commercial chat apps.
- prmoustache 4y agoWhat you are looking for is BigBlueButton: https://bigbluebutton.org/ https://bigbluebutton.org/ It is targetting the virtual classroom market but it does general videoconferencing just right.
- jqpabc123 4y agoSorry, I must be a luddite. I don't get the video conferencing craze. In most cases, I see little real, added value in a live video feed. What I find more generally useful is simple desktop/screen sharing with audio (i.e. GotoMeeting, TeamViewer) If you must see the participants, allow a photo/avatar. Watching real lips moving in a stuttered video is quite chic and nouveau and all ... it's nice with family ... but it doesn't really add much value in a typical business setting IMO. As with most things, there are exceptions but I use desktop sharing way more often.
- baskethead 4y agoYou do sound like a luddite. Also it sounds like you're not used to remote work or interacting with other people in a remote-first environment. Meetings are essential. Seeing people face to face is essential. I had lunch with a teammate recently and it bridges so many gaps you can't do with Zoom. And Zoom is orders of magnitude better than Slack or email. If you don't think that face-to-face video meetings aren't important, then you don't understand human interaction.
- robonerd 4y agoMaybe one in ten meetings qualifies as "essential", and I'm being generous.
- robonerd 4y agoAudio quality is always worse than conference calls in the 80s and 90s (until people started using cell phones.)
- wildzzz 4y agoI used to dread conference calls whenever most people were on their cellphones, me included. Quality was dog shit. If everyone was using a deskphone, quality was better but you could easily tell you were still on a phone call. Whatever system we call into can't make any use of the high quality bandwidth you'd get from internal deskphone calls or between two iPhones using the internet to do voice calls. Work has been giving out USB headsets lately so people can actually talk through the conferencing software on their laptop rather than using a dial-in number. The improvement in voice clarity is enormous and I will never go back to phoning into meetings. I've been encouraging my coworkers to do the same. We don't have webcams on our work PCs so voice or chat is the only option.
- mgamache 4y agoOne of the things that makes Zoom (and for-profit streaming) better is noise cancelation. Zoom has spent a lot of money perfecting video calling without requiring headsets. This is not easy. A second reason is they use some proprietary stream control and compression. It's based on standards and you could copy it, but you would have to license h264 to make this work in open source. Open source requires other people to pay this license (typically it's part of a browser using WebRTC).
- timbit42 4y agoI won't call it perfect if it can't cancel out urination.
- mgamache 4y agonote: you can't really have 1000 people on a call. It's just a live streaming event at that point. You can use standard live streaming techniques for doing this. Yes, it will have 10-20 second latency (or more), but in large calls, most people don't interact with the speaker.
- bombcar 4y agoThis is the answer. If necessary, you livestream a call run on a separate service (think: a call of 5-20 people on Zoom, where the audio and video/screenshare is piped into YouTube).
- mgamache 4y agoRight, if you want to self-host you can run something like Wowza (paid product, but it's a complete solution) https://www.wowza.com/ https://www.wowza.com/
- 2Gkashmiri 4y agoat that point, livestreaming is already a pretty stable affair in the foss world. owncast and peertube both are solid players where you can do good livestreaming. heck, even pixelfed which is a sorta instagram alternative is getting livestreaming so that is a nice idea. consider this. the "host" creates a peertube livestreaming link and sets it as unlisted. that way only people with the link can watch the stream. sure it wont have any moderation but is that possible in a 1000 zoom meeting beyond who can open the mic or share screen?
- bombcar 4y agoI think the idea behind a 1000 person zoom meeting is to "make" everyone feel like a participant, even if the reality is that they're not, they're just watching/listening. Live-streaming makes that more clear.
- DANK_YACHT 4y agoI don't know about Zoom, but I run a video platform and you can definitely have 1000 people on a call. The caveat is that you can't consume everyone's video and audio, so consuming a new person's audio and video takes a second or two. This works fine if you have 2-20 main speakers and a few of the 1000 people "raising their hand" to talk.
- diffeomorphism 4y agoWhy are there so few "enterprise grade zoom alternatives" regardless of being foss or not? - Webex supposedly does 1000 people. - Google meet: No, only up to 500 with "business plus". - MS Teams: Confusing numbers but 1000 for chat only, but 20(?) for audio/video. - Bluejeans: 200 for enterprise; 500 "view-only" - Anything else? So the first answer that comes to mind is that there are no alternatives at all for 1000 participants. If you only need ~200 there are many more options.
- eurasiantiger 4y agoHow many real-life meetings have 200, 500, let alone 1000 active participants? Representational democracy comes to mind, which is interesting, because the ”representational” part only exists to mitigate this very problem. Maybe there is a systemic lesson here.
- dartharva 4y agoIf you really want to address hundreds and thousands of people at once, maybe you're better off livestreaming on YouTube or Twitch.
- speedgoose 4y agoI have been in a MS team meeting with 1000+ participants where the presenter had video enabled. But maybe 1000 is the max and the number of people was higher because counting fast in a distributed system is hard.

- corrral 4y ago- You need 3 clients, minimum—Web, iOS, Android—or you're not an alternative. None of them can be way different from or far worse than the others. - Like 90% of the benefit of Zoom (and other large video & voice chat providers) is their backend infrastructure. You cannot justify replicating that for a small single-customer or small group installation. It'd be far too expensive. So your open-source solution is ~always going to be worse. ("We've also had mixed results testing with team members far away on rough connections, where audio/video was workable in zoom but sometimes unworkable with our internal setup.") - "they can't really do department meetings or let alone an all-hands type of meeting with ~1000 people on the call." Those should be broadcast as one-way streaming video, anyway. Set it up like a live video "podcast" or twitch stream with text chat for questions from the audience, if needed.
- djohnston 4y agoI'm not familiar with the nitty gritty of video streaming infra but I'm curious, with the crazy array of services on AWS/most other cloud providers, what in particular is missing or cannot scale down cost efficiently?
- everforward 4y agoI would guess a big part is switching/routing specifically geared towards low-latency audio/video. Just as an example, they probably use UDP for latency, which has no ordering as part of the protocol. However, for streaming stuff, you really want to drop out of order packets and prioritize whatever the latest packet is. Zoom probably has some kind of custom routing that handles that. If they get congested or clients are unstable, it prioritizes serving the latest audio/video rather than trying to push things out in the order they came in, only for the Zoom client to discard the out of order packets anyways. Amazon can't really do that, because they don't know which bits of data are the ordering. On the pricing side, people are probably the component that scales the least. You're probably going to need a dedicated person to monitor/fix/upgrade it, and deal with calls from people who have issues. Between salary and benefits, that's at least a 6 figure expense. Zoom's most expensive tier is $240/license/year, so $100,000 would buy you 416 licenses. And $100,000 is a lowball here; that's roundabouts a $60k salary, and the other $40k is paid out in benefits/space/etc. This also doesn't count the bandwidth charges, nor the hardware to run the system on. Imo, it's also just generally a bad idea to DIY anything business-critical that isn't a core competency of the company. It tends to cause issues. What do you do when the person that built this bespoke Zoom alternative quits? Can you risk it breaking and not working until you can hire someone new and they figure out how it works? You could hire 2 of them, but Zoom is definitely cheaper then. What do you do if the open source project gets abandoned? It also distracts from things that actually make you money. It makes more sense to me to focus on your core line of business, and use the additional proceeds to just pay for Zoom.

- web007 4y ago1000 _participants_ on a call, or 1000 _viewers_? Our org switched from Google Meet to their streaming equivalent once we hit around 250 people, nothing worked well with that many participants. Lucky for your org, streaming has been a solved problem since the 90s! It looks like Jitsi might support streaming by itself, or you can find online tutorials on Nginx + Varnish RTMP streaming and DIY if you prefer. To answer your literal question, there is no enterprise grade open-source zoom alternative because it's incredibly difficult and hard to make work for free. You have seen how hard just in your N=1000 sample size. Adding in self-hosted STUN or TURN or building your own proxy and video muxer is only going to be harder. There's a reason YouTube, Twitch, Facebook, Instagram, Vimeo, etc. are good at it, because they're zillion dollar companies that can afford to invest in the massive infrastructure and engineering required to make it not-terrible.
- baskethead 4y agoWith a 1000 people you should be streaming. There's no conceivable way 1000 people can have an interactive meeting.
