Vellum Integrations

Facebook is the world's largest social network. We build technologies that help people connect with friends and family, find communities, and grow businesses. From fundraising to offering life-saving help in a Facebook post or signing up to donate blood, we’re inspired by the ways people show up for each other in times of need. The Facebook app helps you connect with friends, family and communities of people who share your interests. Connecting with your friends and family as well as discovering new ones is easy with features like Groups, Watch and Marketplace.

X (formerly known as Twitter) is one of the world's largest social networks. Follow your interests. Hear what people are talking about. Join the conversation. See what’s happening in the world right now. We believe real change starts with conversation. Here, your voice matters. Come as you are and together we’ll do what’s right (not what’s easy) to serve the public conversation.

Velt is a full-stack collaboration SDK that enables developers to embed rich, real-time, and asynchronous collaboration features into web applications with minimal effort. With Velt, you can add contextual comments (à la Figma or Google Docs), live presence indicators, shared editing, “follow me” view modes, and Slack/Meet-style huddles (audio, video, screen sharing). Velt also offers built-in Loom-style recording (screen, camera, or audio), complete with AI-powered transcription and auto-summaries, so users can leave video or voice feedback and later search or scrub to relevant bits. Additional collaboration tools include in-app notifications, mentions, reactions, arrows/highlights for annotation, analytics dashboards for tracking engagement, and flexible UI components you can style to match your app’s branding. It handles all the complexity, real-time syncing, conflict resolution (via CRDTs), offline handling, scaling, and optional self-hosting.
