TL;DR: An open-source video conferencing API removes licence fees and gives you full control of your data. It replaces those costs with servers, bandwidth, and engineering time you cannot avoid. The licence is free. The operation is not. Choose open source when sovereignty is mandatory and you have WebRTC expertise on staff, not when the goal is simply to spend less.
Open source is the obvious answer right up until you run it in production.
A team evaluates video platforms, sees the licence cost of an open-source option is zero, and reasonably concludes it is the cheapest path. Six months later two engineers spend most of their week on media servers, and a failed session during a board meeting has become an executive-level problem.
That outcome is not an argument against open source. It is an argument against evaluating it on licence cost. Open source solves a genuine and sometimes non-negotiable problem: total control of your infrastructure and your data. It simply does not solve it for free.
This guide covers what you actually get, what it costs once operations are counted, where open source is clearly the right call, and the middle path most regulated buyers end up taking.
An open-source video conferencing API is a freely licensed codebase you host and operate yourself. You get the media server, signalling, and client code, plus the right to modify all of it. You also take on installation, scaling, monitoring, security patching, and support, which the licence does not cover.
Jitsi is the best known example, and it is genuinely capable software. Others exist across the WebRTC ecosystem with different trade-offs around scale and complexity.
The important distinction is between the software and the service. Open source gives you the software. Running it reliably for real users is a service, and somebody has to provide it. That somebody is either your team or a vendor you pay.
What does open source actually cost?
The licence is free and the operation is not. Real costs are servers, bandwidth, and engineering time for scaling, monitoring, patching, and incident response. Analysis of self-hosted video deployments repeatedly finds that the cheapest tools by licence cost become the most expensive once development time is included.
Published comparisons of self-hosted platforms reach this conclusion consistently. One review of open-source video options notes that the cheapest tools by licence cost become the most expensive when development time is factored in, and frames the real choice as free meaning either a shared public instance with its privacy trade-offs, or the full operational cost of production self-hosting.
The line items nobody budgets for are these.
- Media servers sized for peak concurrent load, not average load
- Network traversal infrastructure so users behind corporate firewalls can connect at all
- Bandwidth, which is the cost that scales hardest and fastest with usage
- Monitoring and alerting, because a silently degraded video session is worse than an outage
- Security patching on a stack that is directly exposed to the internet
- On-call coverage, because meetings fail in real time and cannot wait for Monday
- Ongoing WebRTC expertise, which is scarce, expensive, and hard to replace when it leaves
The last item is the one that ends most self-hosting projects. Real-time media is a specialist discipline. Teams that build this capability discover it concentrates in one or two people, and those people become a single point of failure for a system the whole organisation depends on.
When is open source the right choice?
Open source is right when you need to modify the platform itself, when your volume is high enough that per-minute pricing exceeds your fully loaded operating cost, or when regulation requires infrastructure nobody else can touch. It is the wrong choice when the only motivation is reducing a licence line item.
Three situations genuinely justify it.
You need to change the platform. If your product requires custom media processing or behaviour no vendor exposes, source access is the only route. This is rare and you will know if it applies to you.
Your volume is very high. Past a certain scale, metered per-minute pricing exceeds what it costs to run your own infrastructure including staff. Calculate the crossover honestly, with fully loaded engineering costs rather than server costs alone.
Regulation requires it. Defence, intelligence, and some government contexts mandate air-gapped or fully controlled environments. Here the cost comparison is irrelevant, because hosted services are not permitted at any price.
If none of these describe you, the honest reason for choosing open source is usually budget, and that reason tends not to survive contact with the second year of operating costs.
Is there a middle path?
Yes. On-premise deployment of a commercial platform gives you the data control of self-hosting with vendor support and a maintained product. You keep the sovereignty position that made open source attractive, without asking your team to become real-time media engineers.
Most organisations that consider open source are actually solving for control rather than cost. They want meeting data to stay inside infrastructure they own, under their own jurisdiction, with no third party able to reach it.
That requirement does not need a self-built stack. On-premise and white-label deployment of a commercial platform achieves the same data position. The software runs on your infrastructure, the data never leaves it, and the vendor remains responsible for the product working.
The trade-off is a licence cost in exchange for not owning the operational burden. For regulated buyers this is usually the better deal, because digital sovereignty is the actual requirement and self-operation was only ever the assumed means of achieving it.
Ask one question to decide: would you rather your engineers maintained a media server, or built the product your organisation actually sells? For most teams the answer settles it. Our guide to why sovereignty matters for enterprise covers the procurement side in more depth.
Conclusion
Three things to carry into the decision.
Separate the software from the service. Open source gives you the first for free and says nothing about the second, which is where the real cost lives.
Name your actual requirement. If it is control rather than cost, on-premise commercial deployment meets it without the operational burden.
Cost the engineering, not just the servers. Fully loaded staff time is what decides whether self-hosting is genuinely cheaper, and it usually arrives at a different answer than the licence page suggests.
Frequently Asked Questions
It is a freely licensed codebase you host and operate yourself, including the media server, signalling, and client code, with the right to modify all of it. The licence does not cover installation, scaling, monitoring, security patching, or support, which become your responsibility.
The licence is free. Running it is not. You pay for media servers sized to peak load, network traversal infrastructure, bandwidth, monitoring, security patching, on-call coverage, and specialist WebRTC engineering time. Published comparisons find the cheapest licences frequently produce the highest total cost.
Choose it when you must modify the platform itself, when your volume is high enough that metered pricing exceeds your fully loaded operating cost, or when regulation mandates air-gapped infrastructure. If the only motivation is reducing a licence line item, the second year of operating costs usually reverses the decision.
Yes. On-premise or white-label deployment of a commercial platform runs the software on infrastructure you control, so meeting data never leaves your environment, while the vendor remains responsible for maintaining the product. This meets the same sovereignty requirement without building an in-house media engineering capability.
Real-time media expertise, specifically WebRTC, plus infrastructure skills for scaling media servers, configuring network traversal for users behind firewalls, monitoring session quality, and responding to live incidents. This expertise is scarce and tends to concentrate in one or two people, which creates a single point of failure.

Need full data control without the operational burden?
On-premise deployment keeps meeting data inside infrastructure you own, under your jurisdiction, with a maintained product and vendor support behind it. Tell us your compliance constraints and we will show you what that looks like in practice.
