Zoom open source alternatives

The one thesis that will save you a week

Zoom sells reliability. Every open-source alternative on this page can host a video call. The difference is what happens when 30 people join at once, when latency drifts, when the connection wobbles. Zoom paid for that reliability with an army of engineers and a global media network. Every alternative is asking you to pay for it with either your ops time or a smaller room. So the honest question isn't "which is the Zoom clone." It's how many people, at what quality, are willing to accept your infra?

Answer that and the two projects below sort themselves in about a minute.

Why teams are leaving Zoom in 2026

Three complaints keep repeating in r/selfhosted, r/privacy, and enterprise IT circles:

1. 40-minute limit on the free tier. Fine for informal chats; annoying for family calls, tutoring sessions, or study groups. Paid tiers start at $14.99/user/mo — a real cost for hobby use.
2. Privacy history remains a scar. The 2020 "not really end-to-end encrypted" scandal changed how privacy-conscious teams evaluate Zoom. Some have never come back.
3. Regulated industries can't use it. Government, defense, education, and healthcare orgs that require data-sovereignty guarantees often can't use SaaS video conferencing at all.

The open-source answer is genuinely small: two mature projects with very different personalities.

The two that matter

Jitsi — the deploy-anywhere quick answer

Jitsi (30k stars, pushed within days, Apache-2.0) is the modal self-hosted video conferencing tool. Docker-compose stack, browser-based, no client install for participants. Fine for small-to-medium meetings (up to ~30-50 people depending on your bandwidth), degrades gracefully to audio-only when networks strain.

Jitsi is what people run when they want "a Zoom-shaped room, on my server, in an hour." It's what meet.jit.si (the free public instance) runs on. Real-time transcription and recording exist but are separate stacks — the base install gives you a video room.

Pick Jitsi if: you want a fast deploy, Apache-2.0 license, and rooms up to ~30 people. Also pick it for internal team standups, client calls, or community events.

Skip Jitsi if: your rooms are 100+ people, or you need enterprise features like breakout rooms with rich moderation, polls, and integrated whiteboards.

BigBlueButton — the education-first heavyweight

BigBlueButton (9k stars, pushed within days, LGPL-3.0) is a different animal. Built for online classrooms — presentations, polls, breakout rooms, chat, shared whiteboards, external video playback, integrated recording. Every feature a teacher wants for a two-hour lecture, packed in.

The trade-off is complexity. BBB is a serious Ubuntu-only deploy (their production install script). It's not "docker compose up." It's "provision a server, run our installer, follow the runbook." Once running, it handles 50-150 participants per session comfortably. Moodle and Canvas integrations are first-class.

Pick BigBlueButton if: you're running education, training, or webinar sessions — anything longer than 30 minutes with structured content. Also pick it for LMS integration.

Skip BigBlueButton if: you want quick informal chats, or your team isn't ready for a full Ubuntu server deploy. This is not a toy.

Decision framework: pick by session shape

Team standups, client calls, casual meetings

Pick Jitsi. Deploy in an afternoon, use immediately.

Online teaching, training, webinars

Pick BigBlueButton. Nothing else is remotely close for structured multi-hour sessions.

Community events, meetups, open hangouts

Pick Jitsi. Public jitsi.meet URLs are shareable, no signup needed.

Regulated industry (healthcare, government, defense)

Pick Jitsi self-hosted if quick deploy matters; BigBlueButton if features matter.

Solo tutoring, small classes

Try BigBlueButton. The features designed for teachers are worth the setup pain.

You just want free video without Zoom's 40-min limit

Use meet.jit.si — Jitsi's public instance. Free, no signup, no time limit.

Deploy difficulty on a $6 VPS

Video conferencing is bandwidth-heavy. Your VPS choice matters:

• Not really on a $6 VPS: Video calls need bandwidth. A CX22 (20 TB traffic/mo) handles small internal use; anything larger needs a bigger box or CDN-fronted setup.
• 2-4 hours on CX32 (8 GB, better bandwidth): Jitsi. Docker-compose is straightforward but TURN server config and TLS take iteration.
• Half a day on a dedicated Ubuntu box: BigBlueButton. Their bbb-install-2.7.sh script does the heavy lifting; you provide a clean Ubuntu 20.04 or 22.04 server, a real hostname, and a valid Let's Encrypt certificate.

Bandwidth reality: a single participant in HD video uses ~1.5 Mbps up and down. Ten participants is 15 Mbps aggregate on your server. Fifty is 75 Mbps sustained. Budget bandwidth-appropriate hosting; don't put video conferencing on a shared or oversubscribed VPS.

License and commercial-use notes

• Jitsi (Apache-2.0): Fully permissive. Embed in commercial products with no obligations.
• BigBlueButton (LGPL-3.0): Weak copyleft. Fine for internal use. If you modify BBB itself and redistribute those modifications, they must stay LGPL. Wrapping BBB in a proprietary UI is fine.

Cost math (small team, one year)

• Zoom Pro: $180/year per user
• Zoom Business, 10 users: $2,400/year
• Zoom Enterprise: phone call, budget $30-50/user/mo
• meet.jit.si (free public Jitsi): $0/year, no signup
• Self-hosted Jitsi on DigitalOcean 4vCPU/8GB Droplet: ~$576/year infra + your time
• Self-hosted BigBlueButton on a dedicated 8-core server: ~$500/year infra (needs more compute + bandwidth) + your time

Rough rule: for teams under 5, Zoom's free tier plus a paid host account for scheduling is often cheaper than self-hosting. For classes, training, or teams above 10, self-hosted math starts winning.

Migration tips (Zoom to open source)

• Recordings do not transfer. Download and archive your Zoom recordings before migration.
• Meeting URLs will change. Update calendar entries, help docs, embedded widgets, and recurring bookings.
• Test at your target scale before going live. A 5-person test call reveals nothing about how 30 people will behave.
• Bandwidth-test from your target audience's geography. Video conferencing degrades cross-continent unless you have TURN relays near each region.
• For BigBlueButton, use the LMS integration (Moodle, Canvas, Chamilo) if you have one. It's cleaner than sharing URLs.
• Run parallel for one week. Book meetings on both systems; ask attendees which they preferred. Real user feedback beats spec-sheet comparison.

What you shouldn't do

Don't self-host video for a team of 5. Zoom's free tier handles 40 minutes; extend with a $14.99 host account. Self-hosting adds bandwidth and ops cost you don't need.

Don't cheap out on the server. Video is CPU- and bandwidth-hungry. A cheap VPS with oversubscribed bandwidth gives you unusable calls at scale. Rent bigger; measure; downsize if idle.

Don't skip TURN configuration. Without a properly configured TURN relay, participants behind restrictive corporate firewalls will fail to connect. This is the #1 "why is my Jitsi broken" support ticket.

Final recommendation matrix

• "Team meetings, client calls, community events" → Jitsi
• "Online teaching, training, webinars" → BigBlueButton
• "Free public video without signup" → meet.jit.si
• "Regulated industry, must self-host" → Jitsi (quick) or BBB (feature-rich)
• "I just want to drop 40-min Zoom limit" → meet.jit.si
• "LMS integration required" → BigBlueButton

Frequently asked questions

Is Jitsi really as reliable as Zoom?

For small rooms (under 30 people), yes if you configure it properly. Zoom's global media network gives it an edge for cross-continent calls and 100+ person rooms. If your rooms are internal team standups or client calls, Jitsi is functionally equivalent.

Can I record meetings?

Yes with both. Jitsi has an add-on called Jibri that provides recording and streaming. BigBlueButton records natively — the recording UI is built in and produces MP4 + slide-synced playback.

Do these work on mobile?

Jitsi has native iOS and Android apps that work well. BigBlueButton is browser-based with mobile-friendly views but not native apps. Participants can join from any mobile browser.

How do I handle end-to-end encryption?

Jitsi supports E2E encryption for meetings up to a certain size. BigBlueButton uses TLS in transit and doesn't currently offer full E2E. For maximum privacy, self-host Jitsi and enable E2E in configuration.

What's the largest room I can host?

Jitsi comfortably handles 30-50 participants on a well-provisioned CX32 or larger. BigBlueButton handles 50-150 per session on a dedicated server. Beyond that you're into distributed setups with multiple media servers — a real infrastructure project.
