Over 780 SDKs Ready for HarmonyOS: Empowering Developers to Build Apps Efficiently

The vibrant HarmonyOS ecosystem is rapidly expanding its capabilities, significantly empowered by a robust and diverse Software Development Kit (SDK) landscape. Data from the National SDK Management Service Platform reveals that typical mainstream applications integrate around 20 third-party SDKs each, underscoring their pivotal role. For HarmonyOS developers, these partner SDKs serve as crucial conduits, bridging the operating system with application development and offering a rich array of technical and commercial functionalities to drive efficient innovation. To date, over 780 HarmonyOS ecosystem partner SDKs have been released, spanning 21 distinct domains, providing developers with a solid foundation for building high-quality HarmonyOS applications.

A strong testament to this growth was on full display at the 2025 Huawei Developer Conference (HDC), where 27 SDK partners from critical sectors including security authentication, media, artificial intelligence, risk control, mapping, and device communication converged, highlighting the burgeoning vitality of the HarmonyOS SDK ecosystem.

Security Authentication: In today’s digital landscape, the integrity of user data and privacy is paramount. Robust security authentication processes are no longer a nice-to-have but an absolute necessity for user trust.

Companies like Yisha Technology are streamlining user verification with their password-free authentication eTAS and eTDS Secure Shield SDKs, enhancing both user experience and security. Kolan’s sMFA Multi-Factor Authentication SDK fortifies user identity security, while its Digital Signature SDK and Collaborative Signature SDK strike a perfect balance between compliance and convenience for digital signatures, driving the digital transformation of government and enterprise operations. Yuncong Technology’s Cloud Shield Liveness Detection SDK offers system-level secure camera-based liveness detection, a solution already adopted by numerous financial institutions. Aurora Security Authentication integrates carrier gateway authentication, enabling millisecond-level counter-attacks against illicit activities and seamless global access, efficiently safeguarding business operations.

WeiZhen Video’s Smart Encoding SDK and Mobile Super-Resolution Enhancement SDK are delivering sharper, smoother visual clarity for live streaming, video-on-demand, and real-time communication (RTC) scenarios. Agora, Qiniu Cloud, RongCloud, and Huawei Cloud Conference are also contributing significantly: Agora’s Real-time Audio RTC SDK, Qiniu Cloud’s Audio-Video SDK, and RongCloud’s IM Instant Messaging SDK and RTC Audio-Video SDK empower developers to swiftly build features like audio-video calls and live streaming, fostering high-quality, cross-region, cross-device, and cross-scenario interactions across various applications. Huawei Cloud Conference’s HarmonyOS SDK, built upon HarmonyOS’s distributed and all-scenario connectivity architecture, offers enterprises a consistent “HarmonyOS Smart Meeting” experience across multiple devices, bolstering collaborative efficiency.

Artificial Intelligence: Xunfei Open Platform SDK brings forth its Spark Cognitive Model, alongside capabilities in image and text recognition, intelligent translation, speech recognition, and speech synthesis. These SDKs are designed to revolutionize human-computer interaction, intelligent customer service, and enterprise productivity, aiming to bridge the final mile in AI application deployment.

Financial Services: Sidy Information’s Securities SDK, now adapted for HarmonyOS, provides comprehensive coverage for core securities business modules including account opening, online services, trading, financial mall, and dual recording for wealth management.

E-commerce: In the bustling e-commerce sector, Youzan App’s Store Opening SDK offers a versatile, industry-agnostic e-commerce solution for applications, enabling developers to rapidly integrate store-opening functionalities and build personalized e-commerce platforms.

Mapping: Enhanced mapping and navigation capabilities are injecting new momentum into smart mobility and location-based services. Amap Open Platform SDK and Daxi Navigation SDK deliver precise and fluid positioning and navigation experiences for HarmonyOS users, supporting the intelligent ecosystem’s deployment across logistics, lifestyle services, and numerous other applications.

Device Communication: With the rapid advancement of the Internet of Things and smart terminals, efficient inter-device communication is fundamental to ecosystem synergy. Yinji Digital Key SDK offers fully managed enterprise-grade digital key services and has fully integrated the Xinghan technology. Yingshi Cloud Open Platform SDK focuses on video surveillance scenarios, enabling secure remote device control and management.

Security and Risk Control: As an indispensable foundational capability for all applications facing evolving security threats, security and risk control SDKs are crucial. SanWei XinAn’s SSL VPN SDK, Qi An Xin Security SDK, and Zhizhangyi Security SDK provide diverse security solutions to safeguard HarmonyOS terminals environments, ensuring system stability, reliable operations, and data security.

Information Push: Gexin Message Push SDK ensures the accurate delivery of messages, offering developers statistical analysis of push results to enhance user engagement and application stickiness.

Customer Service: Yi Qia Customer Service Platform SDK provides a readily integrable, full-featured online customer service system, facilitating seamless server-to-user communication to boost customer satisfaction and operational efficiency.

System Tools: Tencent Docs Browsing Engine and Foxit PDF SDK offer robust support for a variety of document manipulation scenarios, enhancing user experience in productivity and office applications.

Statistics: Data intelligence and operational statistics are increasingly vital in the digital age. Umeng+ Statistics Analysis SDK delivers precise user behavior insights for developers, aiding in product optimization, market decision-making, and the creation of closed-loop business strategies.

Gaming: LeBian Games’ Split Download SDK assists game developers in achieving lightweight app packages and rapid distribution, while FairyGUI provides professional UI solutions for game developers, already integrated into multiple HarmonyOS game titles.

The concentrated showcase of dozens of SDKs at HDC2025, alongside the release of over 780 SDKs, represents a significant achievement in the HarmonyOS ecosystem’s commitment to open collaboration. It is the innovative investment and technical support from these SDK partners that enables HarmonyOS to achieve continuous breakthroughs in security, reliability, intelligent interaction, and all-scenario synergy, offering users and developers ever-richer, more flexible, and more dependable choices.

The journey of the HarmonyOS ecosystem has been profoundly shaped by its collaborative partnerships, including those in the SDK domain. Looking ahead, HarmonyOS will continue to join forces with a wider array of partners, deepening technological integration and expanding application boundaries to jointly construct an open ecosystem characterized by the Internet of Everything and intelligent, interconnected experiences.
