Our Offering

We build collaboration tools that match — and often exceed — the capabilities of Slack. Whether you need a team chat, a support community, or a private workspace, our Slack clone development can be tailored for your exact use case.

Real-Time Messaging & Channels

We implement one-on-one and group chat with public/private channels, @mentions, threads, replies, and unread tracking — powered by WebSocket or Firebase for real-time updates across devices.

Audio & Video Calling Integration

Built-in voice and video calling features using WebRTC, Twilio, or Agora. Includes group calls, screen sharing, mute controls, and low-latency performance across browsers and mobile devices.

Role-Based Access & Permissions

Define user roles (admin, moderator, member), manage channel visibility, message restrictions, file uploads, and access levels using flexible permission layers and team hierarchies.

File Sharing & Storage

Enable secure file uploads, cloud storage (S3, GDrive), and inline previews for documents, images, and videos. Supports drag-and-drop, previews, and version control if needed.

Notifications & Alerts

Push notifications, email alerts, custom sounds, and real-time badges. Fine-grained control for user preferences including @mentions, channel activity, and DND (Do Not Disturb) modes.

Search & Message History

Advanced full-text search across all messages, files, and channels. Search filters by user, date, keyword, and more. Includes message history retention and export tools.

Multi-Tenant Architecture

Support multiple workspaces in a single platform with isolated data, branding, and billing. Perfect for SaaS startups or companies managing multiple teams or clients.

Third-Party App Integrations

Integrate with tools like Google Calendar, GitHub, Notion, Zoom, Zapier, and more. Build custom integrations via APIs and webhooks to automate workflows and increase productivity.
