What we compare

Every WebRTC SDK Service capability an Indian product team needs, in one place

From a two-developer startup embedding in-app calling to a 100-engineer platform building a full video conferencing product — find and compare the right WebRTC SDKs service provider.

In-App Voice Calling SDK

iOS, Android and JavaScript SDKs that embed one-to-one and group voice calling inside your app — no phone number required for app-to-app calls, with Indian TURN servers keeping media local and latency below 80ms.

From ₹0.50/min in-app

Get matched

Video Conferencing SDK

Multi-party HD video with adaptive bitrate for variable Indian network conditions — drops gracefully from 720p to 360p on a Jio 4G handoff without dropping the call. Recording, background blur and screen share included.

From ₹0.80/min video

Get matched

PSTN Bridge & Number Masking

Bridge your WebRTC session to a PSTN call so participants without your app can join on a regular phone number — with number masking so neither party's real number is exposed to the other.

From ₹0.40/min PSTN bridge

Get matched

Screen Share & Co-browsing

Let agents or experts share their screen or co-browse the customer's session during a WebRTC call — built into the same SDK session, no separate plugin required, works on Android Chrome and iOS Safari.

From ₹0.10/min add-on

Get matched

Session Recording & Storage

Record WebRTC sessions to cloud storage on Indian infrastructure — dual-stream (participant + screen share), available via API within 60 seconds of session end, stored per DPDP Act 2023 data residency requirements.

From ₹0.12/min recorded

Get matched

Session Quality Analytics

Per-participant MOS score, jitter, packet loss, bitrate and TURN server region — live during sessions and in post-session reports. Alerts when quality degrades below threshold so your support team can intervene.

Included with all plans

Tell us your platform and session type

Voice-only, video, screen share or conferencing — and your target platforms (iOS, Android, web) and expected peak concurrent sessions so we match SDK capacity.

We match you with verified SDK providers

Filtered by Indian TURN server availability, platform SDK quality, adaptive bitrate performance on Indian mobile networks, PSTN bridge capability and per-minute pricing at your session volume.

Sandbox with Indian TURN servers in 24 hrs

We arrange sandbox credentials and direct access to the provider's Indian TURN infrastructure so you test real media latency on Airtel, Jio and BSNL before making any commercial decision.

First live session in days

A basic iOS or Android in-app voice integration typically goes from sandbox to production in 3–7 days. Video with PSTN bridge is typically 1–3 weeks. Free to buyers, always.

Indian TURN Server PoPs

WebRTC media travels peer-to-peer when possible, but NAT traversal on Indian mobile networks (especially Jio CGNAT) requires TURN relay. TURN servers in Mumbai or Chennai cut media latency from 200ms to under 80ms. We verify this.

Check TURN locations

Adaptive Bitrate on 4G

Indian 4G networks fluctuate between 2 Mbps and 50 Mbps within a single session. SDKs that do not adapt codec and resolution in real time produce choppy video on mid-range devices. We test ABR performance on Jio and Airtel 4G.

Test on Indian networks

iOS & Android SDK Quality

Battery drain, background call handling, CallKit/ConnectionService integration and mid-call network switches all affect production quality. We review code-level SDK quality and community support, not just demo apps.

Why This Matters

Why Choosing an Indian WebRTC SDKs Service Provider Matters for Low-Latency Calling

WebRTC calls between two Indian mobile users should travel peer-to-peer with latency under 80ms. On Indian mobile networks — especially Jio's carrier-grade NAT where direct P2P is blocked — calls must relay through TURN servers. A provider with TURN servers in Mumbai or Chennai routes this relay domestically in under 20ms. A provider whose nearest TURN is in Singapore or Frankfurt adds 180–220ms of relay latency, which manifests as conversation-breaking audio lag. We test actual P2P and TURN-relay latency on Indian mobile networks for every listed provider before listing, and reject any SDK whose TURN infrastructure is not on Indian soil.

Indian TURN server PoPs confirmed in Mumbai and/or Chennai — tested, not vendor-claimed
Adaptive bitrate tested on Jio 4G with simulated 2–50 Mbps fluctuation during sessions
iOS CallKit and Android Connection Service integration confirmed — calls appear in native call screen
DPDP Act data residency confirmed for session recordings and metadata stored on Indian infrastructure

Vinay Rao ★ 4.9 Trusted Partners

"We built telemedicine video consultations with a global WebRTC SDK first. Patients on Jio in tier-2 cities consistently complained about lag. The issue was TURN relay going to Singapore. Telecoms Supermarket matched us with EnableX whose TURN is in Mumbai. Latency dropped from 240ms to 58ms. Patient satisfaction scores for video quality improved by 31 points."

CTO, Telemedicine startup, Hyderabad

Nisha Shah ★ 4.9 Trusted Partners

"Our marketplace connects freelancers and clients. Many clients do not install our app — they need to join a call from a browser or regular phone. The Telecoms Supermarket comparison flagged which WebRTC SDKs included PSTN bridge with number masking. Kaleyra's SDK does both: in-app sessions for app users, masked PSTN bridge for everyone else. One SDK, one bill."

Head of Engineering, Freelance marketplace, Bengaluru

Aryan Kapoor ★ 4.9 Trusted Partners

"We needed CallKit integration so incoming WebRTC calls appear on the iOS lock screen like a normal phone call. Three of the five SDKs we shortlisted claimed CallKit support but it was broken or undocumented. Telecoms Supermarket's vetting included a code-level review of CallKit integration. The two SDKs that passed both had clean implementations. We shipped the feature in a week."

Common Questions

WebRTC SDKs for India, explained clearly

Quick answers to common questions about plans, providers, and services for businesses and individuals.

WebRTC enables direct peer-to-peer voice and video communication between devices. On Indian mobile networks, carrier-grade NAT often blocks direct connections, making TURN servers essential. A WebRTC SDKs service provider with TURN servers in India keeps latency low (10–25ms), while overseas servers can add 180–240ms, affecting call quality. This makes domestic TURN infrastructure a key factor when choosing WebRTC SDKs services.

Adaptive bitrate (ABR) adjusts audio and video quality in real time to match changing network conditions, helping maintain stable calls. For WebRTC Voice SDK deployments, Opus is the preferred audio codec, while VP8 and H.264 are widely supported for video. A reliable WebRTC SDK integration should deliver smooth performance even on fluctuating Indian mobile networks.

CallKit (iOS) and ConnectionService (Android) let WebRTC Calling SDK apps display incoming calls using the native phone interface, improving the user experience. Since implementation can vary across platforms, a trusted WebRTC SDKs service provider should offer stable, production-ready support that works consistently across iOS and Android devices.

PSTN bridging allows users without your app to join WebRTC calls using a regular phone number. The WebRTC SDKs service provider connects WebRTC participants and PSTN callers through a virtual bridge while masking real phone numbers to protect privacy. PSTN usage is typically billed separately from in-app WebRTC SDKs services.

WebRTC recordings containing identifiable voices or faces are personal data under the DPDP Act 2023. A compliant WebRTC SDKs service provider should store recordings on Indian infrastructure, support secure retrieval and deletion, and provide tools that simplify compliant WebRTC SDK integration for businesses.

Zoom and Google Meet are ready-to-use applications, while a WebRTC Calling SDK provides APIs, libraries, and infrastructure to build voice and video features into your own product. Businesses choose WebRTC SDKs services when they need custom branding, workflows, and seamless WebRTC SDK integration within applications such as telemedicine, marketplaces, or edtech platforms.
