What Is Video Conferencing Software? (Zoom Alternatives for Small Business)

What Is Video Conferencing Software?

Video conferencing software is an application — or increasingly, a browser-based service — that enables real-time, two-way audio and video communication between two or more participants over the internet. Modern platforms also include screen sharing, chat, virtual backgrounds, recording, and breakout rooms. The technology that underpins most modern video conferencing is WebRTC (Web Real-Time Communication), an open standard maintained by the W3C that allows browsers to establish peer-to-peer media streams without plugins or proprietary software.

What began as a tool for enterprise conference calls has become a primary business communication channel across industries. Client consultations, team standups, sales demos, job interviews, and training sessions all routinely happen over video. McKinsey research from 2025 found that 50% of all business meetings are now conducted virtually, a figure that has remained stable since the post-pandemic normalization of remote and hybrid work.

How Does Video Conferencing Software Work?

When a meeting begins, the conferencing platform establishes a media stream between participants using one of two architectures: peer-to-peer (P2P) or server-mediated. In a P2P connection powered by WebRTC, video and audio travel directly between participants' devices, which reduces latency and server costs. For calls with many participants — typically more than four — platforms route media through a Selective Forwarding Unit (SFU) server, which receives each participant's stream and distributes only the relevant feeds to each viewer, reducing bandwidth load on individual devices.

The video is compressed using codecs — H.264 and VP8/VP9 are the most common — which reduce the data transmitted while preserving acceptable visual quality. Network conditions are monitored in real time, and adaptive bitrate streaming adjusts quality dynamically to prevent call drops when bandwidth decreases.

Zoom vs Google Meet vs Microsoft Teams for Small Business

Zoom is the most recognized video conferencing brand globally. Its free plan supports unlimited one-on-one meetings but limits group calls to 40 minutes — a constraint that regularly interrupts client meetings at inconvenient moments. Paid plans start at $14.99 per user per month (Pro). Zoom generated $4.4 billion in revenue in FY2025, reflecting its dominant enterprise position, but that market dominance has not translated into pricing relief for small businesses.

Google Meet is available for free with a Google account and integrates naturally with Google Calendar and Gmail. It supports up to 60-minute group meetings on the free tier. However, advanced features like recording, noise cancellation, and attendance tracking require a Google Workspace subscription starting at $6 per user per month.

Microsoft Teams has 300 million or more daily active users and is deeply integrated into the Microsoft 365 ecosystem. For businesses already paying for Microsoft 365, Teams is effectively included. For those that are not, standalone Teams requires a Microsoft 365 Business Basic plan at $6 per user per month. Teams is feature-rich but considered complex to configure for small teams without IT support.

Browser-based alternatives built on WebRTC — like Aicente Action Meet — eliminate the download barrier entirely. Research shows that browser-based tools achieve a 23% higher participant join rate because guests do not need to install software, create accounts, or remember passwords. For client-facing meetings where the guest experience is critical, this friction reduction translates directly into more completed calls.

Frequently Asked Questions

What is video conferencing software?

Video conferencing software is a platform that enables real-time audio, video, and screen sharing between participants over the internet. It can be installed as a desktop or mobile application or accessed directly through a web browser using WebRTC technology. Modern platforms support features including recording, virtual backgrounds, breakout rooms, and meeting scheduling integrations.

What is the best free video call app for small businesses?

For small businesses, the best free video call tool is one that requires no download from the guest side, has no hard time limits, and integrates with scheduling and messaging tools already in use. Google Meet is the strongest free option from established providers. Browser-based platforms like Aicente Action Meet go further by eliminating the account-creation requirement for guests and including team messaging, scheduling, and CRM tools in a single flat-rate subscription.

Can I do video meetings without downloading anything?

Yes. Tools built on WebRTC technology run entirely in modern browsers — Chrome, Firefox, Edge, and Safari — without any plugin or application install. This is the primary advantage of browser-based video conferencing for client-facing businesses: guests join with a single link click, and no technical friction stands between the meeting invitation and the call.

How does WebRTC work?

WebRTC (Web Real-Time Communication) is an open-source, browser-native API that enables real-time audio and video communication without plugins. It uses ICE (Interactive Connectivity Establishment) to discover the best network path between participants, DTLS (Datagram Transport Layer Security) to encrypt all media, and SRTP (Secure Real-time Transport Protocol) to deliver audio and video streams. Signaling — the initial exchange of session metadata — is handled by the platform's server, but the actual media often travels peer-to-peer, which reduces latency and infrastructure cost.

How much do businesses spend on video conferencing tools per year?

Small businesses spend an average of $2,400 per year on video communication tools, according to industry benchmarks. That figure rises significantly when screen recording, transcription, and virtual event tools are added separately. Consolidating video meetings with other business tools — messaging, CRM, scheduling, and more — under a single flat-rate platform reduces both per-tool costs and the administrative overhead of managing multiple vendor relationships.
