1Fix the driver behind crashes, sound loss and screen glitches2Repair Windows errors before they cause bigger problems3Scan for outdated or missing drivers - takes under a minuteFor most organizations, start with Jitsi Meet. It is browser-first, open source, and has documented self-hosting paths. Pick BigBlueButton instead when teaching, webinars, recording, and structured presentation workflows are central. Pick Nextcloud Talk if Nextcloud is already your collaboration hub. Pick LiveKit when you are building a custom real-time media product rather than deploying a ready-made meeting room.
The right choice depends less on a theoretical “best” and more on meeting style, existing systems, media-routing needs, and the VPS resources you can reserve. The sections below map those decisions to the published requirements and operational work for each project.

Choose by meeting model first
Self-hosting changes the decision from “which app has the most features?” to “which operating model can your team run reliably?” A casual team meeting, a recorded class, a collaboration-suite call, and an embedded video feature have different priorities.

There is no controlled, same-hardware benchmark covering all four projects. Treat feature fit and documented infrastructure requirements as the evidence-based basis for selection; do not assume one project is universally fastest or supports a particular number of participants on an arbitrary VPS.
Jitsi Meet: the default for browser-first meetings
Jitsi describes the project as a set of open-source projects that lets users deploy secure, scalable and easy-to-use video-conferencing platforms. That positioning makes it the sensible first evaluation for a general-purpose service where people should join from a browser without installing a specialized client.
Why it is a strong default
- It is designed around browser-based WebRTC meetings and can be deployed on infrastructure you control.
- The project publishes self-hosting guidance, Debian packages and Docker deployment options, giving administrators more than one installation approach.
- It can serve recurring team rooms and guest meetings without forcing the organization into a larger collaboration suite.
Published prerequisites
The current quick-start path supports Debian 12 (Bookworm) or newer and Ubuntu 24.04 (Noble Numbat) or newer. You need root or sudo access, nginx, OpenJDK 17, DNS for the service name, and a trusted certificate. The Jitsi guide specifically notes that a trusted certificate is important for mobile clients. Its self-hosting documentation says encrypted HTTPS is necessary for WebRTC and recommends an internet-facing server with a certificate for a domain registered in DNS.
Jitsi deployment sequence
- Prepare the host. Choose a supported Debian or Ubuntu release, give the VPS a public address, apply operating-system updates, and create a non-root administrative account with sudo.
- Publish DNS. Create the service hostname and point its A record, and AAAA record when IPv6 is enabled, to the VPS. Wait for the record to resolve before requesting the certificate.
- Install the documented stack. Follow either the Debian-package path or the Docker path from the Jitsi project. The package path uses nginx and OpenJDK 17; do not mix package and container instructions casually.
- Enable trusted TLS. Complete certificate issuance for the registered hostname and verify that the meeting page loads over HTTPS. Browsers will otherwise block or restrict WebRTC features.
- Set meeting policy. Decide whether rooms require authentication, whether guests wait for a moderator, and who can create rooms. Apply the project’s current configuration guidance rather than copying settings from an older release.
- Test real clients. Join from a desktop browser and a phone on a separate network. Check camera and microphone permissions, screen sharing, reconnect behavior and audio when one participant changes networks.
- Operate the service. Schedule updates, monitor CPU, memory, network and disk, back up configuration, and document how to restore the hostname and certificates.
Where Jitsi needs careful sizing
The reviewed Jitsi guides do not publish one universal VPS size or a guaranteed participant cap. Capacity changes with simultaneous speakers, camera resolution, screen sharing, recording, network conditions and whether media is relayed through additional services. Begin with measured concurrency targets, leave headroom for spikes, and increase CPU, memory or network capacity when monitoring shows sustained pressure. A small test room is not evidence that a production event will fit the same plan.
BigBlueButton: choose it for classes and structured events
BigBlueButton is the better match when the meeting itself has a teaching or webinar workflow: an instructor or presenter, moderated participation, presentations, breakout-style activities and recordings. It is not merely a generic room server with a few extra buttons; its value is the event model.

Production baseline for version 3.0
BigBlueButton’s current 3.0 production installation guidance calls for the following starting point:
| Requirement | Published value or condition | How to interpret it |
|---|---|---|
| Operating system | Ubuntu 22.04, 64-bit | Use the supported release for the 3.0 installation path, not an arbitrary distribution image. |
| Memory | 16 GB RAM, with swap | A production starting point for the documented deployment, not a guarantee for every class size or recording load. |
| CPU | Eight CPU cores with high single-thread performance | Prefer a dedicated instance with strong per-core performance; shared, oversubscribed CPU can undermine media quality. |
| Recording disk | 500 GB free disk | Required when recordings are retained. The guide states 50 GB is sufficient if recording is disabled. |
| Network | 250 Mbit/s symmetrical bandwidth | Plan for both upload and download at that rate; actual demand varies with concurrent media and presentation traffic. |
| Firewall | TCP 80 and 443; UDP 16384–32768 | Open the documented ranges at both the VPS firewall and any upstream network filter. |
| Addressing and naming | Hostname suitable for an SSL certificate; IPv4 and IPv6 | Make DNS and certificate issuance part of provisioning, not a last-minute fix. |
Dedicated capacity is part of the design
The project recommends dedicated compute instances for cloud deployments and publishes example classes from several major infrastructure providers. The practical implication is more important than the provider name: avoid noisy-neighbor CPU, reserve enough disk for recordings, and verify that the provider delivers the required symmetric bandwidth and IPv6.
BigBlueButton deployment checklist
- Provision a clean 64-bit Ubuntu 22.04 server meeting the memory, CPU, disk and network baseline.
- Assign a stable hostname and create matching DNS records for IPv4 and IPv6.
- Obtain a trusted certificate for that hostname before inviting users.
- Allow TCP 80/443 and UDP 16384–32768 through every firewall layer.
- Install the current 3.0 release by following the project’s production installation procedure on the clean host.
- Decide whether recordings are enabled. If they are, monitor free space and define retention and export policies; if disabled, the published disk requirement is lower, but other media and operating-system storage still need headroom.
- Run a rehearsal with the actual presentation formats, microphones, cameras, screen sharing, moderation roles and mobile browsers your event will use.
The 16 GB, eight-core and 250 Mbit/s figures are a dedicated production starting point, not a universal capacity guarantee. Treat a large class or public webinar as a capacity-planning exercise and test it before the event.
Nextcloud Talk: the right answer when Nextcloud is already central
Nextcloud Talk combines video, audio, chat and collaboration with the accounts, files and spaces in a Nextcloud deployment. That integration can outweigh the advantages of a stand-alone meeting service when users already work in Nextcloud and should not switch to another identity and collaboration silo.
What the documentation emphasizes
- Load rises with the number of concurrent active participants, so capacity planning must use simultaneous use rather than total registered users.
- Integrated signaling is described as suitable for small and medium installations. Larger or busier deployments should evaluate the project’s scaling and signaling options instead of assuming the integrated mode will remain sufficient.
- HTTPS is required for browser WebRTC, the technology used by Talk calls. A plain-HTTP test installation can therefore produce misleading camera, microphone or call failures.
Implementation path
- Start with a supported, healthy Nextcloud installation and measure its normal CPU, memory, database and storage load before adding calls.
- Put the service behind a trusted HTTPS certificate and verify browser permissions on desktop and mobile.
- Enable Talk and choose the signaling architecture appropriate to your expected concurrent activity; use integrated signaling only within the small-to-medium scope described by the documentation.
- Test calls while users upload files, edit documents and use chat. The goal is to find contention between collaboration traffic and media, not merely to prove that one call connects.
- Set monitoring and backups for both Nextcloud data and the call-related configuration. A video call that works but cannot be restored after a database or storage failure is not an operational success.
Choose Talk for integration, not because the documentation promises a fixed VPS size. The reviewed material does not state a universal CPU, RAM or participant number; size from concurrent active participants and the rest of the Nextcloud workload.

LiveKit: a media foundation for developers
LiveKit is appropriate when you are engineering a conferencing application, customer-facing real-time feature or embedded media workflow. Its official virtual-machine guide is deployment-oriented: it covers production setup on a cloud VM, including media-ingress networking. That is a different proposition from installing a ready-to-use meeting portal.

- Your product needs its own user experience, room lifecycle, permissions and business logic.
- You need to integrate real-time media into an existing web or mobile application.
- Your team can own authentication, signaling, observability, upgrades and the client experience.
Do not choose it for a turnkey room
If the requirement is “give staff a link and a complete meeting interface,” a finished meeting platform normally involves less application work. With LiveKit, plan the application around the media service: identity and token issuance, room management, ingress and egress behavior, client permissions, failure handling and support documentation.
Production planning questions
- Define whether media enters through browser/mobile clients only or through additional ingress sources, and reserve the required network paths.
- Deploy the VM according to the current production guide, including its media-ingress networking requirements.
- Instrument connection success, packet loss, jitter, CPU, memory, bandwidth and room counts before inviting real users.
- Load-test your actual codecs, resolutions, recording or relay behavior and geographic traffic pattern. The guide does not establish a universal participant limit that can be transferred to every application.
- Document how your application reacts to a failed VM, expired token, blocked UDP path or overloaded media node.
VPS requirements that apply to every option
Operating system and lifecycle
Use a currently supported Linux distribution and the release required by the project you select. Do not assume that a newer distribution is automatically compatible: BigBlueButton 3.0 documents Ubuntu 22.04, while the Jitsi quick-start path documents Debian 12 or newer and Ubuntu 24.04 or newer. Keep a rebuildable installation record and schedule security updates.
DNS, public addressing and TLS
Create the final hostname before production. Publish A and, where required, AAAA records, confirm they resolve from outside the VPS, and issue a trusted certificate. Browser WebRTC depends on HTTPS for Jitsi and Nextcloud Talk, and BigBlueButton requires a hostname suitable for its SSL certificate. Test renewal before the first large event.
Firewall and media routing
Open only the ports documented by the chosen project. BigBlueButton’s published production range is TCP 80/443 and UDP 16384–32768. Jitsi, Nextcloud Talk and LiveKit have different deployment components and may require additional media or signaling paths; use their current guides rather than copying BigBlueButton’s firewall range.

CPU, memory, bandwidth and disk
- CPU: Media encryption, encoding, recording and concurrent sessions can compete for cores. BigBlueButton explicitly calls for eight high-performance cores; other projects require measurement against your workload.
- Memory: Reserve RAM for the operating system, web server, media processes, databases and monitoring. Do not treat a provider’s advertised maximum as available application memory.
- Bandwidth: Plan both directions. BigBlueButton’s baseline is 250 Mbit/s symmetrical; a one-way bandwidth figure is not an equivalent substitute.
- Disk: Recordings consume space over time. BigBlueButton documents 500 GB free for recordings, or 50 GB when recording is disabled. For every platform, set alerts and retention rules before disks fill.
Backups and monitoring
Back up configuration, identity data, certificates or certificate automation state, and recordings where they are business records. Monitor service health, certificate expiry, disk growth, CPU saturation, memory pressure, packet loss and failed joins. A backup that has never been restored is only an assumption, so perform a restoration exercise on a separate host.
Security, privacy and access control
Self-hosting moves responsibility to your team. Use least-privilege administration, SSH keys, timely operating-system updates and a documented emergency access path. Keep management interfaces off the public internet when the project supports that arrangement. Require room authentication or moderation for sensitive meetings, and decide how guest links expire or are revoked.
Encryption in transit protects browser connections when TLS is correctly configured; it does not eliminate endpoint risk, recording access risk or administrator access to stored data. Define who may start recordings, where recordings are stored, how long they remain available and how participants are notified. For classes and webinars, publish a moderation policy for microphones, cameras, screen sharing and disruptive guests.
Troubleshooting by symptom
The page loads, but camera or microphone access fails
- Confirm the URL uses HTTPS and the certificate is trusted by the browser or phone.
- Check that the browser granted camera and microphone permissions for the exact hostname.
- Test a second browser and a second network to separate endpoint policy from server configuration.
Participants connect but cannot hear or see one another
- Review the product’s documented UDP and media-routing requirements and every firewall layer.
- Check whether a corporate network blocks UDP or requires a relay path supported by the product.
- Inspect packet loss, CPU saturation and bandwidth rather than increasing only the VPS disk.
Calls work until a class or meeting grows
- Compare the failure time with CPU, memory, bandwidth and recording-disk graphs.
- For Nextcloud Talk, compare the event with concurrent active participants and other Nextcloud activity.
- For BigBlueButton, verify that the host meets the dedicated 3.0 baseline and that recordings have not consumed the free disk.
- For Jitsi or LiveKit, load-test the real room pattern; no universal size or participant cap is established in the reviewed documentation.
Mobile users fail while desktop users succeed
Check certificate trust and the complete HTTPS chain first. Jitsi’s quick-start guidance specifically calls out a trusted certificate for mobile clients. Then test mobile browser permissions and the network’s UDP policy.
A practical decision process
- Need a conventional browser meeting service? Evaluate Jitsi Meet first.
- Is the core event a class, webinar or presentation with recordings and moderation? Evaluate BigBlueButton on a dedicated host meeting its published baseline.
- Do users already live in Nextcloud? Evaluate Nextcloud Talk and size it for concurrent active participants plus normal collaboration load.
- Are you building the product experience yourself? Evaluate LiveKit and budget engineering and operations for the surrounding application.
- Can your VPS provide the required public networking, CPU, memory, disk and IPv4/IPv6? If not, change the infrastructure plan before choosing software.
- Can you operate DNS, TLS, firewall rules, updates, backups and monitoring? If not, use a managed operation or assign those responsibilities explicitly; self-hosting is an operating commitment, not just an installation choice.
Final recommendation
Use Jitsi Meet as the starting point for a general-purpose, browser-first service. Use BigBlueButton for education and structured online events where its workflow and published production baseline fit the job. Use Nextcloud Talk when keeping calls inside an existing Nextcloud environment is the main benefit. Use LiveKit when the meeting interface is part of a software product you are building.
Whichever path you choose, provision the supported operating system, public DNS, trusted TLS, documented firewall rules, reserved media capacity, recording storage and tested backups before inviting real users. That preparation determines reliability more than the label on the VPS plan.
