Selecting the right video conferencing and collaboration platform is a key decision for technology leaders in any enterprise. Rising license costs and evolving compliance requirements have many CTOs and procurement teams looking for an open source alternative to Microsoft Teams that delivers control, cost savings, and flexibility. Among the options available as open source zoom alternatives, Jitsi stands out. Let’s look at why companies are moving to Jitsi and how it stacks up against Microsoft Teams in features, costs, control, and migration.

The hidden costs of Microsoft Teams many overlook

At first glance, Microsoft Teams may seem affordable, especially since it comes with Microsoft 365 subscriptions. But the real costs go well beyond the license fees.

Microsoft 365 licenses vary in price depending on the plan. A company with 100 users on a mid-tier plan may spend close to $19,000 annually just on licenses. While Teams is included, licensing is only part of the equation.

Additional costs arise from:

• Advanced features: Things like meeting recordings with transcription, compliance archiving, and hosting webinars usually require upgraded plans or extra add-ons.
• Data residency and compliance: Companies with specific regulatory needs might need additional controls or third-party tools, increasing expenses.
• Limited data control: Since Microsoft manages Teams’ backend, organizations have less ability to control where data is stored or apply custom encryption methods.

These factors add up, especially for businesses aiming to customize their collaboration tools or meet strict compliance. Users might also face productivity challenges due to Teams’ complexity, leading to more training and support costs.

Remember, licenses are just one piece of total ownership costs. Vendor dependencies, infrastructure limits, and user experience all affect your budget and operational flexibility.

What “open source alternative” really means for your team

When you hear “open source alternative,” you might think of unfinished projects or limited support. But for enterprise teams, open source platforms like Jitsi offer more than just free software.

Control and transparency

Open source means full access to the code. This translates into:

• Customization: Tailor the platform to your specific workflows and policies.
• Security audits: Independent reviews confirm the platform’s security and compliance.
• Data sovereignty: Self-hosting lets you keep data in your preferred location.

Predictable costs and savings

Though the software itself is free, you’ll have infrastructure and support costs. Still, this model removes per-user subscription fees, shifting control—and costs—to your own environment.

Avoiding vendor lock-in

Proprietary platforms tie you to their feature pipelines, pricing changes, and infrastructure. Open source lets you maintain autonomy and avoid those dependencies.

Active community and innovation

Open source projects benefit from community contributions, with rapid feature updates and security fixes you don’t have to wait for.

When weighing open source alternatives, IT leaders must consider that shifting away from vendor-managed solutions also shifts some responsibility to your internal team or partners.

Comparing Jitsi and Microsoft Teams: features, costs, and control

Here’s a clear look at where Jitsi and Microsoft Teams differ:

Aspect	Microsoft Teams	Jitsi
Licensing Model	Subscription-based with Microsoft 365	Open source software; pay hosting and support only
Costs	License fees plus add-ons	Infrastructure and maintenance costs only
Feature Set	Broad collaboration (chat, calendar, file sharing, Office integration)	Mainly video conferencing and chat; connects via APIs
Compliance & Security	Built-in enterprise certifications (HIPAA, GDPR)	Compliance possible with proper configuration and hosting
Administration	Centralized management with Azure AD ties	Manual setup; server admins handle management
Integrations	Deep Office 365 and app marketplace integrations	API support but fewer ready-made integrations
Video Conferencing	Webinars, breakout rooms, large meetings	Peer to peer by default; scaling webinars needs extra setup
Data Control	Data stored in Microsoft cloud with limited export	Data stays on your premises or cloud; full data control

Federation and peer-to-peer video

Jitsi uses peer to peer video conferencing to reduce server load, improve latency, and support privacy on small meetings. It also enables federated environments for collaborations between organizations with customized domain rules.

Teams relies on centralized servers without federation, which limits flexibility but ensures consistent experiences.

Real company transitions to Jitsi

Consider a mid-sized consulting firm with about 100 staff using Microsoft Teams via an Office 365 E3 plan. Their license costs reached roughly $23,000 annually.

Faced with rising costs and compliance concerns, their CTO launched a Jitsi pilot on internal cloud servers.

Migration steps:

• Month 1: Started with a 20-person pilot testing audio/video and controls on self-hosted Jitsi.
• Month 2: Conducted training and feedback sessions, running Teams and Jitsi side-by-side.
• Month 3: Rolled out Jitsi company-wide for all video conferencing, keeping Teams for email and files.
• Month 4: Retired Teams video licenses; shifted webinars to Jitsi plus third-party webinar tools.

Challenges and results:

• User resistance required focused training on benefits.
• Initial scaling problems were resolved with better server clusters and load balancing.
• The company cut Microsoft licensing costs by limiting Teams use to email and documents.
• Data sovereignty improved, as video session data stayed within their infrastructure.

The move delivered better cost control, compliance, and flexibility, saving roughly $10,000 yearly on conferencing.

Gains and compromises when choosing Jitsi

Gains:

• Lower costs: No per-user conferencing licenses simplifies budgeting.
• Data control: You decide where and how data is stored.
• Customization: Adjust UI, features, and integrations to fit your needs.
• Open standards: Avoid vendor lock-in; adapt as technology evolves.
• Peer-to-peer video: Improves latency and lowers server costs for small meetings.

Compromises:

• Ecosystem integration: Teams’ deep Office 365 connections are hard to match.
• Out-of-the-box compliance: Microsoft covers compliance broadly; Jitsi requires custom setup.
• Administration: Teams offers centralized admin tools; Jitsi needs hands-on server management.
• Large webinars: Teams supports these natively; Jitsi might need added software.
• User familiarity: Teams is widely known, easing adoption and training.

You must weigh these against your priorities and resources.

The migration roadmap at scale

Switching from Teams to Jitsi for 100 users takes detailed planning and coordination:

1. Assessment: Map current Teams use, workflows, and integrations.
2. Setup: Provision servers with load balancing and security for Jitsi.
3. Pilot: Trial Jitsi with a test group, monitor and collect feedback.
4. Training: Prepare materials and sessions on new tools and practices.
5. Parallel run: Keep Teams active while users adopt Jitsi.
6. Full deployment: Transition all video conferencing to Jitsi; phase out Teams conferencing.
7. Integration: Connect Jitsi to chat, calendar, or document systems with APIs.
8. Support: Build help desks, offer troubleshooting, and maintain infrastructure.

Expected hurdles:

• Resistance to change and differences in features.
• Technical work to link Jitsi with legacy systems.
• Delivering uptime and quality comparable to Teams.

A structured approach with leadership is key to minimize disruption.

Is now the right time? Your decision checklist

Before moving to an open source Teams alternative like Jitsi, ask yourself:

• Do your current Teams costs justify exploring open source to reduce total expenses?
• Can your compliance team ensure Jitsi meets regulatory needs?
• Does your infrastructure support reliable Jitsi hosting?
• Are your workflows tied to Office 365, or adaptable to Jitsi?
• Is your team ready for new technology, with training resources in place?
• Is vendor independence and customization a priority over an all-in-one platform?
• Are your webinar and large meeting needs manageable with Jitsi or do they require extra tools?

Answering these honestly helps decide if a full switch or a phased approach suits your organization.

Conclusion

Choosing Jitsi as an open source alternative to Microsoft Teams gives you more control over costs, data, and customization. While Teams shines with deep Office 365 integration and built-in compliance tools, its subscription fees and vendor dependence pose challenges.

A 100-person company switching to Jitsi cut costs substantially and improved data sovereignty, though it required solid planning and technical effort.

CTOs and IT leaders must balance cost, control, compliance, and features to see if an open source option fits their collaboration goals.

Take the next step by assessing your readiness and piloting Jitsi alongside your existing tools. Working with experienced consultants can help you plan migration and ensure compliance, leading to an informed decision that meets your business needs.
