Share a game, a film, or your holiday photos with up to 20 friends, and let them watch from a browser tab with nothing to install. The host picks a screen, window, browser tab, or camera, then sends an invite link or a four-digit room code, with an optional room password. Friends open it on a desktop or phone, press Play, and chat or react while it runs, with optional on-screen chat. A microphone switch adds spoken commentary, with a choice of input device and voice volume. Video travels directly between participants where possible, and a self-hosted server can add automatic forwarding for networks that block direct links. Sharing settings cap resolution from 480p to 1440p, frame rate up to 60 fps, and audio at 64, 128, or 192 kbps, with Clarity, Balanced, and Fluency presets and a choice of VP8, H264, or automatic codecs. Viewers get playback controls, picture-in-picture, fullscreen, light and dark themes, and a connection topology view. The interface follows the system language in Chinese or English, with a visual-only mode for a text-free look. Piik App adds native capture on Windows, macOS, and Linux, while a hosted site works from any desktop browser. A self-hosted site can set a site passphrase, a viewer limit per room, and automatic cleanup of empty rooms.

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.

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.

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.
