Apache-2.0, 24K+ GitHub stars, no account required, fully self-hosted." date: "2026-04-13" tier: 1 authors: ["team"] tags: ["zoom", "jitsi", "bigbluebutton", "open-source", "self-hosted", "video-conferencing", "2026"] --- ## TL;DR **Jitsi Meet** is the best open source alternative to Zoom in 2026 — Apache-2.0 licensed, 24K+ GitHub stars, and requiring zero accounts for guests. Any participant can join a Jitsi meeting with a link, no app install or sign-up needed. For education teams or organizations with strict recording and compliance requirements, **BigBlueButton** (LGPL-3.0, 9K+ stars) is the stronger choice. Zoom Pro costs $14.99/host/month; both Jitsi and BigBlueButton are free to self-host. ## Key Takeaways - **Jitsi Meet** (Apache-2.0, 24K+ stars) is the most frictionless option — no account required for guests, browser-based, simple Docker deploy, optional E2E encryption - **BigBlueButton** (LGPL-3.0, 9K+ stars) is optimized for structured meetings and education — breakout rooms, polls, shared notes, whiteboard, and recording built-in - Both support screen sharing, chat, hand-raising, and HD video up to 720p - Self-hosting Jitsi saves $180/host/year vs Zoom Pro; $540/host/year vs Zoom Business - Jitsi requires 3 services (web, backend, prosody); BigBlueButton requires a dedicated server with its own installer --- ## Why Teams Look Beyond Zoom Zoom's pricing and data model have created friction for teams that prioritize control: **Per-host cost.** Zoom Pro charges $14.99/host/month. An organization with 20 hosts that run regular video calls pays $3,597/year before any advanced features. Large meetings (1,000+ attendees) require add-on webinar licenses. **Data handling.** Zoom processes meeting audio and video through its servers even for end-to-end encrypted sessions in some configurations. For healthcare (HIPAA), education, and government teams, cloud-processed video is a compliance barrier. **Recording storage.** Cloud recording fills up the allotted quota quickly on Pro plans. Local recording requires the desktop app, not available to browser-only participants. **Guest friction.** Every Zoom meeting nudges non-Zoom users to install the app. Browser join works but with feature limitations. Open source alternatives flip this: self-hosted means your data never leaves your servers, and Jitsi's join-by-link model removes the signup barrier entirely. --- ## Jitsi Meet vs BigBlueButton: Feature Comparison | Feature | Jitsi Meet | BigBlueButton | |---------|------------|---------------| | License | Apache-2.0 | LGPL-3.0 | | GitHub Stars | 24K+ | 9K+ | | Guest Account Required | ❌ | ❌ | | Max Participants | ~75 (recommended) | ~150 (recommended) | | Screen Sharing | ✅ | ✅ | | Recording | ✅ (Jibri add-on) | ✅ (built-in) | | Breakout Rooms | ✅ (basic) | ✅ (full instructor control) | | Polls | ✅ (basic) | ✅ (full, with results) | | Shared Notes | ❌ | ✅ (collaborative pad) | | Whiteboard | ✅ (Excalidraw-based) | ✅ (multi-page) | | Chat | ✅ | ✅ | | Raised Hands | ✅ | ✅ | | Mobile App | ✅ iOS, Android | Browser-only (limited) | | E2E Encryption | ✅ (optional) | ❌ | | Kubernetes Support | ✅ (JitsiMeet k8s) | ❌ (bare-metal/VM only) | | Setup Complexity | Low (Docker) | High (dedicated installer) | | Min. Server Specs | 4 GB RAM, 4 vCPU | 8 GB RAM, 4 vCPU | **Jitsi Meet wins for general-purpose video calls** — quick to deploy, frictionless for guests, and scalable horizontally. **BigBlueButton wins for education and webinars** — its instructor tools (slides, polling, breakout rooms with auto-assignment, attendance tracking) are purpose-built for structured sessions. --- ## Setting Up Jitsi Meet (Self-Hosted) Jitsi's Docker deployment is the fastest path to a working install. It bundles the web interface, backend (Jicofo), video bridge (JVB), and Prosody XMPP server. ### Prerequisites - Ubuntu 22.04 or Debian 12 (recommended) - 4 GB RAM, 4 vCPU minimum (8 GB for 50+ concurrent users) - A domain with DNS A record pointing to the server - Ports 443 (HTTPS), 10000/UDP (media), and 4443/TCP open in your firewall ### Docker Compose Setup ```bash # Clone the Jitsi Docker repository git clone https://github.com/jitsi/docker-jitsi-meet.git cd docker-jitsi-meet # Copy the sample env file cp env.example .env # Generate secure passwords ./gen-passwords.sh # Create required directories mkdir -p ~/.jitsi-meet-cfg/{web,transcripts,prosody/config,prosody/prosody-plugins-custom,jicofo,jvb,jigasi,jibri} ``` Edit `.env` with your domain and settings: ```bash # Required settings in .env HTTP_PORT=80 HTTPS_PORT=443 TZ=America/New_York # Your public domain PUBLIC_URL=https://meet.yourdomain.com # Enable authentication (recommended for private deployments) ENABLE_AUTH=1 ENABLE_GUESTS=1 AUTH_TYPE=internal ``` Start the services: ```bash docker compose -f docker-compose.yml -f docker-compose.override.yml up -d ``` Jitsi is accessible at `https://meet.yourdomain.com` — HTTPS is automatic via the built-in Caddy or Nginx container. ### Adding User Accounts (If Auth Enabled) ```bash # Add a host account docker compose exec prosody prosodyctl --config /config/prosody.cfg.lua \ register alice meet.yourdomain.com secretpassword ``` Authenticated users can start meetings; guests can join by link without an account (if `ENABLE_GUESTS=1`). ### Enable Recording (Jibri) Jibri records meetings to local disk or S3 using a Chrome browser in a headless container. Add it to your compose stack: ```yaml # Add to docker-compose.yml jibri: image: jitsi/jibri:latest restart: unless-stopped volumes: - ~/.jitsi-meet-cfg/jibri:/config:Z - /srv/recordings:/srv/recordings cap_add: - SYS_ADMIN devices: - /dev/snd:/dev/snd environment: - XMPP_SERVER=prosody - XMPP_DOMAIN=${XMPP_DOMAIN} - XMPP_RECORDER_PASSWORD=${JIBRI_RECORDER_PASSWORD} - JIBRI_RECORDING_DIR=/srv/recordings ``` Jibri requires `SYS_ADMIN` capabilities for Chrome's Xvfb display. On containerized hosts (e.g., VPS with OpenVZ), this may require a KVM/bare-metal instance instead. --- ## Self-Hosting Experience **Jitsi Meet** deploys in 20–30 minutes with the Docker method. The `.env` configuration is well-documented, and the `gen-passwords.sh` script handles credential generation. The biggest operational concern is UDP port 10000 — if your server's firewall or upstream NAT doesn't pass UDP traffic, video will fail. Verify with: ```bash # Test UDP connectivity from an external machine nc -z -u your-server-ip 10000 ``` **BigBlueButton** is significantly more complex. It requires a dedicated Ubuntu 20.04 server (not Docker), runs its own automated installer (`bbb-install.sh`), and takes 30–60 minutes. The installer is opinionated — it configures Nginx, Coturn (TURN server), FreeSWITCH, and the BigBlueButton application layer in one pass. Multi-server scaling requires Scalelite, an additional load balancer. For most teams, Jitsi is the right starting point. For institutions running online learning with 50+ concurrent students, BigBlueButton's structured tooling justifies the setup complexity. For a complete walkthrough of the BigBlueButton install and classroom setup, see [Jitsi Meet vs BigBlueButton 2026](/guides/jitsi-vs-bigbluebutton-2026). --- ## Scale and Performance Expectations Jitsi uses a Selective Forwarding Unit (SFU) architecture through the JVB (Jitsi VideoBridge). Each server can handle approximately: - **4 vCPU / 8 GB RAM**: 75–100 simultaneous video participants per call - **8 vCPU / 16 GB RAM**: 150–200 participants per call For larger calls or multiple concurrent meetings, Jitsi supports horizontal JVB scaling — add more video bridge instances behind a load balancer. A single Jitsi server handles multiple concurrent meetings simultaneously, so a 4 vCPU server can comfortably run 10 small meetings (8 participants each) at once. --- ## When to Use Which **Choose Jitsi Meet** if: - You need general-purpose video calls where guests shouldn't need an account - You want a simple, fast Docker deployment with minimal operational overhead - You handle sensitive conversations that need to stay on your own infrastructure - You need mobile app support (Jitsi has native iOS and Android apps) **Choose BigBlueButton** if: - You're running online classes, webinars, or structured training sessions - Instructor controls (polling, breakout room assignment, attendance, raise hand moderation) are essential - You need built-in recording and playback without a separate Jibri setup For a broader look at all self-hosted video conferencing options, see [Best Open Source Alternatives to Zoom 2026](/guides/best-open-source-alternatives-to-zoom-2026).

The only real cost scaling is server capacity — not per-host licensing. For organizations with 10+ Zoom hosts, the savings easily justify the self-hosting overhead.
