custom video call ui sdk with recording

If you want a custom video call UI SDK with recording, here’s a practical way to think about it and what you can build.

What you likely need

A video calling SDK solution should support:

• 1:1 and group video calls
• Custom UI control over:
  • call screen layout
  • participant tiles
  • mute/unmute
  • camera on/off
  • screen share
  • chat/reactions
• Recording
  • cloud recording
  • local recording
  • audio-only recording if needed
• Call state management
  • ringing, connecting, in-call, reconnecting, ended
• Permissions and auth
  • secure access tokens
• Cross-platform support
  • web, iOS, Android, desktop

Options you can use

1) Use a third-party SDK

Good if you want to ship quickly.

Popular choices:

• Agora
• Twilio Video
• Vonage Video API
• Daily
• 100ms
• Zoom SDK

These usually provide:

• real-time video/audio
• customizable UI
• recording APIs or integrations
• SDKs for web/mobile

2) Build on WebRTC directly

Good if you want full control and lower vendor dependency.

You’ll need:

• WebRTC media handling
• signaling server
• TURN/STUN servers
• recording pipeline
• UI layer
• scaling infrastructure

This is more complex, but very flexible.

Best fit by use case

• Fastest to market: 100ms / Daily / Agora
• Enterprise / high scale: Twilio / Agora / Vonage
• Maximum control: custom WebRTC stack

Recording approaches

Cloud recording

The provider records on the server side. Pros:

• reliable
• no client performance hit
• easy to store/share

Cons:

• usually costs extra
• depends on provider support

Local recording

Recorded from the client app. Pros:

• simpler for single-user capture
• useful for demos or local saves

Cons:

• performance issues
• unreliable for multi-user/group calls

Recommended architecture

A typical setup:

• Frontend: React / React Native / Flutter / native mobile
• Video SDK: Agora/Twilio/Daily/100ms
• Backend: Node.js / Python / Go
• Database: Postgres / MongoDB
• Storage: S3 / GCS / Azure Blob
• Recording service: provider recording API or custom media server
• Auth: JWT token service

Custom UI components you may want

• pre-join lobby
• active speaker highlight
• participant grid
• pinned video
• screen-share view
• recording indicator
• network quality indicator
• chat drawer
• device settings modal

Example feature flow

1. User logs in
2. Backend issues video token
3. User joins call
4. UI renders participants
5. Host starts recording
6. Recording file saved to cloud storage
7. Call ends and recording link is shown
