MiroTalk WebRTC is the front desk for your own video meeting platform, where users register, schedule rooms across your MiroTalk servers, and invite guests by email or link. Each account gets a personal dashboard of upcoming, recurring, and past meetings, with room links ready to copy the moment a call needs to happen. Scheduling works for the whole MiroTalk family, SFU group calls, P2P chats, and broadcast or direct-call rooms, so one calendar front door serves every meeting style you run. Invitations travel by email or plain shareable links, and guests join from any modern browser with no account and no downloads. Turn on SaaS mode and the same platform sells access, with monthly, annual, and lifetime plans handled by Stripe checkout and webhooks while free mode stays completely open. A documented REST API lets your own systems create rooms and manage users, and the official Docker image with MongoDB gets the whole front desk online in minutes. Running on a dedicated VPS on RepoCloud with guaranteed CPU, RAM, and SSD, full root SSH access, and a browser serial console. AGPL-3.0 licensed.

Backed by nearly 30,000 GitHub stars and powering millions of meetings through meet.jit.si, Jitsi Meet is the open-source video conferencing platform that runs entirely in the browser with no plugins or downloads required. The WebRTC-based architecture delivers HD audio and video through the Jitsi Videobridge selective forwarding unit, while Prosody handles XMPP signaling and Jicofo manages conference focus and orechestration. End-to-end encryption uses AES-GCM 128-bit keys exchanged via the Olm protocol, protecting audio, video, and screen sharing through the Insertable Streams API in Chromium-based browsers. Moderators can split participants into breakout rooms with individual password protection, enable lobby waiting rooms for admission control, set meeting passwords, and track speaker statistics with per-participant talk time metrics. Virtual backgrounds leverage TensorFlow.js body segmentation with WebGPU and WebGL acceleration, automatically adapting quality through device tier detection. Server-side recording and YouTube live streaming run through Jibri, while Jigasi provides a SIP gateway for PSTN dial-in and speech-to-text transcription. The platform includes in-meeting chat with private conversations, polls, raise-hand functionality, emoji reactions, and tile and speaker view layouts. Mobile applications for iOS and Android complement the web client, and both web and native SDKs enable embedding video conferences into custom applications. Running on a dedicated VPS on RepoCloud with guaranteed CPU, RAM, and SSD, full root SSH access, and a browser serial console. Apache-2.0 licensed.

For online classes, telehealth visits, and support calls, OpenVidu Meet is a video meeting app that anyone with a link can join from a browser, with no account or download. A room needs only a name, and an optional wizard adds limits on participants (up to 30) and meeting length (up to a day), plus microphone and camera defaults. A shared Moderator or Speaker link admits anonymous guests, a personal link identifies each invited guest, and registered users sign in with their accounts. Developers can embed a room with an iframe or web component, and webhooks report meeting events to as many endpoints as needed. A smart mosaic favors recent speakers and counts the participants it hides, and a status rail shows the recording light, an encryption badge, and the time left. Moderators mute one participant's microphone, camera, or screen share, switch them off for everyone, remove people, and promote others. Virtual backgrounds blur the room or swap in an image, before joining or mid-call. Recordings start by hand or when the first participant, the second participant, or a moderator joins, in grid, speaker, or single-speaker layout. Permitted members can play, download, delete, or share saved recordings by link. End-to-end encryption protects audio, video, chat, and names behind a shared passphrase, though encrypted rooms cannot be recorded. Running on a dedicated VPS on RepoCloud with guaranteed CPU, RAM, and SSD, full root SSH access, and a browser serial console. Apache-2.0 licensed.

Galene is a self-hosted video conferencing system that runs full meetings, lectures, and tutorials in the browser while asking remarkably little of the server it runs on. Every group gets its own page with video tiles, a user list, and a chat pane, and participants join from desktop or mobile browsers with nothing to install. Presenters share a screen or individual windows, stream a video or audio file straight from disk, and switch to blackboard mode when a slide needs resolution more than frame rate. Moderators can warn or remove participants and lock the group, raise-hand status keeps question queues orderly, and anyone can blur their background or exchange files directly with peers. Groups are simple configuration files: set public or private rooms, passwords or login tokens, client limits, and expiry windows, then create users with moderator or presenter privileges using the galenectl command. Automatic subgroups spin up identical breakout rooms on demand, the pattern its author uses to supervise forty students working in pairs during computer science practicals. Calls stay smooth on poor networks because the server adapts video quality per participant, recovers lost packets, and relays media through its built-in TURN server when firewalls block direct paths.

Used daily by millions of educators and learners in over 65 languages and embedded as the default virtual classroom in Moodle Cloud, Canvas, Sakai, D2L, Jenzabar, and Schoology — together comprising more than 75% of the worldwide learning management system market — BigBlueButton has been the leading open-source web conferencing platform for education since its creation at Carleton University in 2007. The platform delivers WebRTC-based real-time audio, video, and screen sharing with a tldraw v2-powered multi-user whiteboard featuring infinite canvas support, allowing multiple participants to annotate slides and draw simultaneously. Breakout rooms support up to eight concurrent groups with collaborative whiteboards enabled by default, and polling with customizable response types lets instructors assess understanding in real time. The built-in Learning Analytics Dashboard answers three questions at a glance: who is attending, who is participating, and who is learning based on poll responses, providing actionable engagement metrics without requiring webcam surveillance. Session recording captures audio, video, slides, chat, and whiteboard annotations for asynchronous playback on any device. The plugin architecture introduced in version 3.0 enables custom extensions, while IMS LTI 1.0 compliance allows integration with Blackboard, Desire2Learn, Pearson Learning Studio, and any conformant platform without custom code. The REST API enables programmatic session management, user authentication, and recording access for custom frontends like the included Greenlight application. Version 4.0 introduces LiveKit-based media and a redesigned interface. Running on a dedicated VPS on RepoCloud with guaranteed CPU, RAM, and SSD, full root SSH access, and a browser serial console. LGPL-3.0 licensed.

Apache OpenMeetings puts the whole meeting in the browser: cameras, a shared whiteboard, the agenda document, and recording controls, all running on your own server. Participants join rooms with audio and video, audio only, or video only, choose camera resolutions and devices, and present by sharing a screen or a single window at selectable quality. Moderators control the floor person by person: who may draw on the whiteboard, present, share or record the screen, mute others, or speak while everyone else stays muted. Multiple whiteboards hold drawings, text, clip art, and imported documents in PDF, office, and image formats, rescaling to fit every participant's screen, and boards can be saved into the drag-and-drop file explorer for the next session. Every meeting can be recorded with all audio streams exactly as heard, then downloaded as MP4 or played back in the integrated player, and the built-in calendar schedules rooms and sends invitations. Breakout rooms split classes and workshops into groups, polls gather decisions live, private and group chat runs beside the video, and telephone users can dial into rooms through the Asterisk SIP integration. Running on a dedicated VPS on RepoCloud with guaranteed CPU, RAM, and SSD, full root SSH access, and a browser serial console. Apache-2.0 licensed.

With over 20,000 GitHub stars and adoption by companies building everything from telehealth platforms to AI voice agents, LiveKit is the most widely deployed open-source real-time communication server available. The Go-based Selective Forwarding Unit handles hundreds of concurrent participants per node with adaptive bitrate streaming, simulcast layers, SVC codec support for VP9 and AV1, and end-to-end encryption. Client SDKs span JavaScript, Swift, Kotlin, Flutter, React Native, Rust, Python, Unity, and ESP32 embedded devices, while server-side APIs cover Node.js, Go, Ruby, Java, Python, Rust, PHP, and .NET. The Agents framework enables building AI-powered voice and video applications — real-time speech-to-text, LLM-driven conversations, and computer vision pipelines — running as server-side participants in any room. Egress records sessions to S3-compatible storage or streams to RTMP endpoints, while Ingress pulls external feeds from OBS via RTMP, WHIP, or SRT into LiveKit rooms. The SIP bridge connects traditional telephony to WebRTC rooms for hybrid conferencing. JWT-based authentication, webhook notifications, room-level moderation APIs, and selective subscription give operators granular control. Deploy as a single binary for development, Docker Compose for production single-node, or Kubernetes with the official Helm chart for distributed multi-region clusters using Redis for state coordination.

Chitchatter is a browser-based chat room for text, voice, video, screen sharing, and file transfers that exists only while its members are connected and keeps no record of what was said. Every visit starts with a random room name generated on your device, a UUID or a readable passphrase, and you invite people with the link or a QR code. Public rooms admit anyone with the link; private rooms also require a matching password. Messages support Markdown, multiline text, and code blocks, and clicking a name opens a direct conversation. Newcomers to public rooms receive the earlier conversation from peers already there, and typing indicators show who is writing. Start an audio or video call, share your screen to walk a relative through a settings problem, or hand over a file of any size, encrypted before it leaves your browser. Public-key checks verify each peer automatically, with a green lock marking everyone who passes and an icon showing whether the link is direct or relayed. Embed a room in any web page with an iframe or a web component that takes a room name, user name, and color mode. Light and dark themes are built in, and notifications and sounds announce new messages while you work in another tab. Close the tab and the transcript disappears.

On game night Sharkord carries voice, webcams, and screen sharing, and on Monday morning it carries the team's threaded chat, all from one server you control. For the gaming crowd, voice rooms offer noise suppression, echo cancellation, webcams up to 2160p, and screen sharing in VP8, VP9, H264, or AV1, with optional simulcast layers for slow viewers. An experimental Bridge app keeps push-to-talk and mute hotkeys working with a game in focus, and plugins add a music bot or a soundboard. For a family group, invite links can carry a role, a use limit, and an expiry, and replies, reactions, custom emoji, pins, and direct messages keep conversation casual, with uploads up to 2 GB each. For a small team, text channels sit in categories with threads, mentions, and search, roles stack with per-channel permissions for private rooms, and OpenID Connect sign-in works with Authentik, Keycloak, Zitadel, Entra ID, or Google Workspace. Admins cap storage per user or role and can sign upload URLs. There is no premium tier, no member cap, no ads, and no tracking, and a built-in marketplace installs plugins in one click.

With over 10,000 GitHub stars and a reputation forged in the frustration of laggy corporate screen sharing, Screego delivers what Microsoft Teams and Zoom screen share consistently fail to provide: instant, high-resolution screen streaming that lets remote colleagues actually read your code. Built on WebRTC peer-to-peer connections, Screego transmits screen data directly between browsers without routing through centralized servers, achieving sub-second latency and native-resolution quality that makes pair programming and code reviews genuinely productive. The server component, written in Go with a TypeScript frontend, deploys as a single binary or Docker container with minimal configuration — set your external URL, generate a secret key, and you're live. An integrated TURN server handles NAT traversal automatically, eliminating the need for separate STUN/TURN infrastructure, with configurable UDP port ranges and support for external TURN servers when scaling beyond a single instance. Authentication supports three modes — requiring login for all actions, only for TURN connections, or none — with user management via simple credential files. Rooms are created instantly and support multiple simultaneous viewers, with system and tab audio sharing available for demonstrations that need sound. The architecture supports reverse proxy deployment behind Nginx, Caddy, or Apache with automatic TLS termination, and recent releases added riscv64 architecture support alongside existing amd64 and arm64 builds.

Add a live support desk to any website with Live Helper Chat, where visitors talk to operators or bots and you own every transcript. Site owners paste a generated embed snippet into any page, and the start-chat fields are customizable. Chats are routed by department, language, location, or custom attributes, wait in a priority queue, and move between agents. Operators, departments, and simultaneous chats are unlimited. Agents watch a visitor type before the message is sent, read pages visited and time on site in the online visitors list, and send proactive invitations to people who linger. Voice, video, and screen sharing run through Jitsi or Agora, and a screenshot shows what the visitor sees. Bot designers chain triggers and actions in a visual builder, call ChatGPT, Gemini, Ollama, Rasa, or any REST API, and hand the conversation to a person when needed. Incoming email becomes tickets beside chats, and extensions connect Telegram, WhatsApp, Facebook Messenger, and Twilio SMS. Staff answer from the browser, a desktop app, a Chrome extension, or iOS and Android apps. Management tools include roles, groups, statistics, transcripts, and an archive, and extensions add two-factor login, LDAP, and single sign-on. It suits banks, healthcare teams, universities, and game studios that must keep chat data in house.

LibreDesk unifies live chat, email, and future channel integrations into a single agent inbox where every customer conversation converges regardless of origin, replacing per-seat-priced tools like Zendesk, Intercom, and Freshdesk with a zero-cost alternative that has surpassed 2,000 GitHub stars. Built on a Go backend with a Vue.js 3 and ShadcN UI frontend, it ships as a single binary requiring only PostgreSQL and Redis. The embeddable live chat widget drops onto any website with a snippet, while the AI assistant handles initial customer queries using answers grounded in your knowledge base before escalating to human agents when needed. Agent copilot drafts replies, summarizes conversation threads, and rewrites messages for tone adjustment directly within the inbox interface. Automation rules trigger on conversation events to tag, assign, and route tickets based on configurable conditions, while auto-assignment distributes workload by agent capacity or custom criteria. SLA management tracks response and resolution time targets with breach notifications, and automated CSAT surveys measure satisfaction after conversation closure. Macros save frequently sent responses as reusable templates that simultaneously set tags and assign conversations. Role-based access control provides granular per-action permissions for teams and individual agents, and SSO supports Google, Microsoft, and any OIDC provider. The HTTP/JSON API and webhook system enable custom integrations with external tools.

MikoPBX gives a small business a complete phone system on a server it controls, with extensions, call queues, IVR menus, and call recording instead of per-seat hosted PBX fees. Follow a call through it: incoming rules per provider match exact numbers or patterns, fall through by priority when nobody answers, and end at a default route. Each employee gets an extension with SIP credentials, forwarding for no-answer, busy, and unavailable states, and an optional recording switch. Queues offer seven distribution strategies, including Ring All, Least Recent, Fewest Calls, and Memory Hunt, and can announce each caller's position and estimated wait. IVR menus play a recorded greeting, route keypad choices to departments or extensions, and fall back to a default number after a set number of retries. Call history filters by caller, destination, or DID, flags missed calls in red, and plays or downloads recordings as WebM, MP3, WAV, or OGG. Voicemail, call transfer, call pickup, and a holiday and night-time switcher serve daily needs, while free and paid marketplace modules, among them a softphone, auto dialer, and LDAP/AD sync, handle the rest. A firewall, Fail2Ban, passkey sign-in, and CrowdSec integration protect the system, and a REST API with more than 250 endpoints lets other tools manage it. The interface speaks 26 languages.
