# Velt

> A complete collaboration SDK that lets developers add contextual comments, notifications, multiplayer editing, presence, cursors, huddles, and recordings to any web product in minutes.

Velt is a developer SDK that provides a full suite of real-time and async collaboration features — including contextual comments, notifications, multiplayer editing, presence indicators, live cursors, huddles, and screen recordings — that can be embedded into any web application in under 5 minutes. It ships with 15+ pre-built, fully customizable UI components that mirror familiar patterns from Figma, Google Docs, Slack, and Frame.io. Velt is SOC 2 Type II and HIPAA certified, supports self-hosting, custom data encryption, and multi-region deployments, making it suitable for enterprise use cases. Teams at Google, X (Twitter), Pendo, Leadpages, and Bigtincan use Velt to ship collaborative features weeks or months faster than building in-house.

- **Contextual Comments** — *Install `@veltdev/client`, wrap any element with `<VeltComments>`, and users can leave pinned, threaded comments on any part of your UI, including canvas, cells, and video timelines.*
- **Notifications** — *Drop in the notifications component to deliver real-time mention, reply, and approval alerts without building a notification system from scratch.*
- **Multiplayer Editing (CRDT)** — *Integrate with Yjs, Tiptap, BlockNote, CodeMirror, Lexical, or SlateJS to enable Google Docs-style co-editing with conflict resolution.*
- **Presence & Cursors** — *Show live user avatars and adaptive cursors across your app, similar to Miro, with a single component.*
- **Huddles** — *Add Slack-style audio/video huddles directly inside your product for real-time collaboration without leaving the app.*
- **Recordings** — *Let users record audio, video, and contextual screen clips and attach them to comments for richer async feedback.*
- **Reactions** — *Enable emoji reactions on any document element for lightweight, expressive engagement.*
- **Live State Sync & Follow Mode** — *Synchronize UI state across users in real time and let one user guide others through a shared view.*
- **AI Enhancements** — *Automated AI review of first drafts and AI-powered comment summaries available as an add-on.*
- **Enterprise Security** — *Self-hosting, custom encryption keys, isolated server/data storage, GDPR APIs, SOC 2 Type II, HIPAA with BAA, and multi-region hosting (EU, APAC, NA).*
- **Third-Party Integrations** — *Connect to Slack, Discord, Microsoft Teams, HubSpot, Close CRM, Zapier, Segment, OpenTelemetry, Resend, SendGrid, AWS S3, GCP, and Azure Blob Storage via webhooks and REST APIs.*
- **Developer Console & DevTools** — *Admin console with analytics, live debugger, data viewer, user activity logs, and a browser DevTools extension for faster debugging.*
