OpenTok is a developer-focused real-time communications platform that exposes WebRTC-based video, audio, and data channels through server-side REST APIs and client SDKs for web, iOS, and Android. Historically known as the OpenTok Platform from TokBox, the offering provides the primitives you need to create custom video experiences: session creation, token-based authentication, stream management, relayed audio/video, and cloud recording and broadcasting.
OpenTok targets engineering teams that need programmatic control over media sessions rather than turnkey meeting software. Use cases include telemedicine visits, remote learning classrooms, customer support video widgets, live interviews, and multi-camera production. The platform emphasizes session-level controls (connect, publish, subscribe), server-side session orchestration, and options to record or broadcast sessions to CDNs.
OpenTok exposes features at both the client and server level: lightweight JavaScript and native client SDKs for embedding in apps, and server SDKs/REST endpoints for creating sessions, issuing tokens, starting/stopping archives, and managing billing and webhooks. The result is a platform intended for building production-grade, custom video workflows rather than out-of-the-box conferencing.
Opentok provides the building blocks to manage real-time video, audio and data between participants in web and mobile applications. Core capabilities include session creation, token-based participant authentication, publishing/subscribing to video streams, adaptive bitrate and codec negotiation, and data channel messaging for synchronized application state.
The platform supports recording (archives) and live streaming to large audiences via HLS/RTMP, enabling both on-demand playback and broadcast workflows. It also offers server-side controls for stream moderation, stream layout rules for recorded archives, and APIs for exporting recorded files to cloud storage.
Opentok adds production features you need in a hosted media platform: TURN/STUN-based NAT traversal, automatic fallback to relayed connections when direct peer-to-peer fails, media encryption in transit, bandwidth management, and diagnostic hooks (logs, metrics, and connection events) to monitor session health.
OpenTok offers these pricing plans:
Pricing for recording, storage egress, and CDN streaming can add to per-minute rates; enterprise customers negotiate custom bundles and committed usage discounts. Check OpenTok's current pricing for the latest rates and enterprise options.
OpenTok starts at $0/month with a developer free tier intended for prototyping and testing. Paid usage generally appears as per-minute and optional monthly subscription charges when you need sustained or high-volume capacity.
Most teams move from the free tier to either pay-as-you-go billing for irregular usage or a predictable monthly subscription that bundles minutes and archive storage. If you expect steady usage, a monthly plan can reduce unit costs compared with pure per-minute billing.
OpenTok costs vary by committed usage and can be negotiated annually with enterprise contracts; many teams pay the equivalent of several hundred to several thousand dollars per year depending on participant minutes, recording needs, and support level. Annual contracts are common for larger deployments seeking volume discounts and a fixed budget for video infrastructure.
If you prefer monthly billing, expect to pay more per unit than with an enterprise yearly commitment. For accurate annual estimates, tally expected participant minutes, archive minutes, storage, and streaming egress and consult the official pricing link.
OpenTok pricing ranges from $0 (free) to $1,000+/month depending on usage and enterprise features. Small prototype projects can run on the free tier or minimal pay-as-you-go spend; production apps with heavy video use or long recordings will be in the hundreds to thousands of dollars per month range. Costs scale with participant minutes, cloud recording time, simultaneous streams, and CDN egress.
For budgeting, calculate expected participant minutes (number of participants × average session duration × sessions per month), add archive minutes, and factor in storage and downstream streaming. Check OpenTok's billing documentation for current per-minute rates and overage policies.
Opentok is used to embed real-time video and audio into custom applications where off-the-shelf meeting products don’t meet integration or UX needs. Typical applications include telehealth platforms that require session recording, consent workflows and HIPAA-aware handling; virtual classrooms with breakout rooms, whiteboard syncing, and scalable broadcasting; and customer support widgets that pop a video call into a web page.
Because the platform exposes low-level session primitives, it’s also used to build multi-camera productions and hybrid events that mix live presenters with remote participants and then broadcast to audiences via HLS or RTMP. Developers build control panels that manage who’s published to the session, layout logic for archives, and programmatic start/stop of recordings for compliance or post-production.
Other uses include peer-to-peer video chat in marketplaces, remote inspection and collaboration tools that need data channels to exchange measurements or annotations, and interactive streaming where low latency is critical (moderated Q&A, auctions, or live support).
Opentok’s strengths include a mature SDK set, flexible session and token-based security, and built-in support for recording and broadcasting. The platform is optimized for embedding custom UIs and for integrating video with existing back-end systems (authentication, billing, data storage). The multi-SDK approach (JavaScript, iOS, Android) lets teams deliver consistent experiences across devices.
The platform’s server-side APIs are well suited to controlled environments where sessions are created and tokens issued to authenticated users. Cloud recording (archives) and RTMP/HLS export remove the need to build and maintain separate recording infrastructure. TURN/STUN support and adaptive bitrate handling reduce the amount of client-side networking code you must write.
On the downside, OpenTok is a developer platform rather than a finished conferencing product: you must build UI, session lifecycle management, and UX flows yourself. That requires engineering resources and knowledge of real-time media concepts. For very high-volume or extremely low-cost use cases, open-source server deployments or commodity SaaS meeting tools may be more cost-effective. Finally, integration and billing complexity (per-minute billing, archive costs, egress) require careful estimation and monitoring.
OpenTok provides a free developer tier intended for evaluation and prototyping. The free tier includes SDK access, developer API keys, and a limited allocation of participant minutes and archive minutes so you can verify integration and basic workflows without initial cost.
The free tier is not intended for production traffic; limits on concurrent sessions, participant minutes, and archive retention exist. When you approach those limits the platform prompts you to upgrade to pay-as-you-go or a monthly subscription.
If you need a production evaluation, contact the sales or support team to request a temporary increase in quota or a short-term trial with production-scale minutes and enterprise features like dedicated support and extended retention.
Yes, OpenTok offers a free developer tier that provides API keys, SDK access, and a limited allocation of test minutes and archive capability for prototyping. The free tier supports development and initial testing but is throttled for concurrent usage and archive time compared with paid plans. For production applications, teams typically move to pay-as-you-go billing or a subscription plan that aligns with expected usage.
OpenTok’s API surface includes both client SDKs and server-side APIs. Server SDKs and a REST API let you create sessions, generate tokens (with roles and expiry), start and stop cloud recordings (archives), and manage project settings. Webhooks notify your back end about session events, archive completion, and stream lifecycle changes.
Client SDKs handle media capture and rendering, device selection, and publishing/subscribing logic. The JavaScript SDK supports modern browsers via WebRTC; native SDKs for iOS and Android wrap platform media stacks and provide callbacks for connection state and quality metrics.
Advanced API capabilities include role-based token generation (publisher, subscriber, moderator), forced disconnects and stream unpublishing from the server, dynamic stream layout configuration for archives, SIP and PSTN interconnect for hybrid calls, RTMP streaming for CDN broadcast, and cloud transcoding/archiving options. The platform also offers diagnostic and logging endpoints for session analytics and troubleshooting.

Opentok is used for embedding real-time video, audio, and data channels into custom web and mobile applications. Developers use it to add video calling, multi-party sessions, recording, and broadcast capabilities to apps for telehealth, education, customer support, and live events. The platform exposes session creation, token-based authentication, cloud recording, and streaming controls so teams can programmatically orchestrate media flows.
Yes, Opentok provides cloud recording (archives) that capture session streams to server-side files. You can start and stop archives via the REST API, configure layouts for recorded streams, and export archives to cloud storage or download them for post-processing. Archive APIs also emit webhooks when recording state changes or files are ready.
OpenTok typically bills on a per-participant-minute basis for active media sessions, with additional charges for recording, storage, and streaming egress. Per-minute rates are tiered by volume and feature set; consult OpenTok's current pricing to see exact per-minute and bundle rates. Large-volume customers usually negotiate committed rates.
Yes, Opentok supports RTMP and HLS export for broadcasting sessions to CDNs and large audiences. You can route a session to an RTMP endpoint for live distribution or produce HLS output for broader compatibility with players and DVR features. These broadcasting features are commonly used for webinars and live events.
Yes, Opentok can be used in HIPAA-compliant telehealth deployments when configured with appropriate controls and agreements. That includes using encrypted media transport, proper access controls, signed business associate agreements (BAAs) where provided, and secure handling of recorded archives. For regulated deployments, work with the vendor sales and security teams to confirm certifications and contractual terms.
Opentok provides client SDKs for JavaScript, iOS, and Android, plus server SDKs in multiple languages. Client SDKs manage device capture, rendering, and media negotiation while server SDKs or the REST API handle session creation, token generation, and archive control. The cross-platform SDK lineup helps deliver consistent experiences across browsers and native apps.
Yes, Opentok supports SIP interconnect to bridge WebRTC sessions with SIP/PSTN endpoints. This enables hybrid workflows where remote participants join from traditional phone systems or external conferencing infrastructure. SIP bridging is commonly used to add dial-in or to connect hardware conference systems to web-based calls.
Opentok uses token-based authentication for session access, where the server issues short-lived tokens with roles like publisher or subscriber. Tokens let you enforce session-level permissions, expire credentials, and control who can publish streams. For enterprise systems, tokens are typically created only after users authenticate with your application back end.
Yes, Opentok exposes connection events, stream lifecycle hooks, and diagnostic metrics that help monitor session quality. You can capture client-side stats (packet loss, jitter, bitrate) and use webhooks or server logs to correlate issues. These tools are useful for building health dashboards and automated alerts for degraded media performance.
Yes, Opentok archives can be exported to cloud storage services and delivered via CDN for playback. The API supports retrieving finished archive files and programmatically pushing them to object storage or a CDN origin. This is useful for long-term retention, compliance, or publishing recordings to a content delivery workflow.
