Speedify SDK is a commercial SDK for embedding Speedify’s channel bonding technology into third-party products. Its target customers include OEMs, software vendors, hardware manufacturers, and network operators. It sits between applications and the operating system’s network stack, intercepting and distributing traffic at the network layer, so in theory applications on the device can benefit transparently without requiring protocol-by-protocol or business-logic changes.
At its core is packet-level channel bonding: it can split traffic from a single video conference, file transfer, or live stream across all available connections, including Wi‑Fi, Ethernet, 4G/5G, Starlink, and satellite links. If a connection drops, it can automatically fail over to the remaining links within milliseconds, with traffic carried through an AES-256 encrypted tunnel. For real-time scenarios, it provides QoS to prioritize traffic such as Teams, Zoom, OBS, RTMP, and WebRTC. The SDK also supports Pair & Share cellular sharing, per-link priority settings, data caps, and rate limits.
The documentation states support for Windows, macOS, Linux, iOS, and Android, and it can also be embedded into Linux routers, gateways, and edge devices. There are two integration paths: customer teams can integrate it themselves using the SDK, documentation, and sample projects; or Speedify’s engineering team can provide custom integration, deployment architecture, and protocol-level customization. On the API side, it offers telemetry APIs and configuration APIs, allowing customers to display network health in their own UI and control bonding modes and data policies.
Pricing is not public, and SDK licensing requires contacting sales. On the server side, customers can choose shared Speedify Cloud, dedicated servers managed by Speedify, or self-hosting. The shared cloud includes 82 PoPs, and the documentation says there are no additional costs beyond the SDK license. Dedicated servers offer up to 1Gbps, scalable bandwidth starting at 3TB/month, static IPs, port forwarding, and an SLA. Self-hosting emphasizes unlimited bandwidth and control over data residency, with support for up to 1,000 devices.
Its strengths are mature network-layer capabilities, broad platform coverage, flexible deployment models, and supporting credibility from third-party security audits and MASA certification information. The downsides are that pricing, licensing details, the actual quality of developer documentation, and connectivity in mainland China are not disclosed. In addition, traffic needs to terminate at Speedify server components, which creates vendor lock-in. It is best suited for live streaming, carriers, in-vehicle/maritime/airborne networks, remote industrial use cases, and hardware vendors that want to deliver “reliable connectivity” as a product capability.
The documentation does not provide information on mainland China access, payments, or compliance, so this remains unknown. If using it in China, users should carefully verify Speedify node connectivity, cross-border link compliance, self-hosted server locations, and payment/contract arrangements.
