Kuikly is a cross‑platform framework under TDS Client Services, built on Kotlin Multiplatform. A single codebase targets Android, iOS, HarmonyOS, H5, and mini programs, delivering high performance and dynamic updates for efficient full‑platform app development.
Tencent's Kuikly framework uses Kotlin Multiplatform to let developers write foldable-screen adaptation logic once and reuse it across Android, iOS, and HarmonyOS, handling routing, animations, gestures, and safe-area insets through unified models.
The author documents a 7.5-hour experiment using AI-assisted coding with Tencent's Kuikly cross-platform framework to build a multimodal AI chat app for Android, iOS, and HarmonyOS, detailing component selection, custom module creation, debugging via logcat, and iterative UI polishing, demonstrating how AI + Kuikly eliminates cross-platform duplication and boilerplate.
Tencent's Kuikly framework introduces TurboDisplay, a first-screen acceleration solution that caches rendered nodes and uses dual-thread parallel rendering to achieve instant page loads on repeat visits, reducing load times by 60-80% in production apps like QQ Games and Tencent Maps.
QQ Music migrated 9 React H5 pages and 3 components to the Kuikly cross-platform framework using an AI-assisted workflow, achieving over 90% AI-generated code adoption, reducing development time from 3+ days to under 1 day per page, and cutting page load time by 90% while surpassing original React performance.
Tencent's Kuikly team introduces Kuikly AI, a Harness Engineering foundation for cross-platform development that addresses AI code quality and client complexity challenges through open-sourced Rules for framework conventions and Skills for scenario-specific AI agents, alongside MCP, design-to-code, preview tools, and migration agents.
The author enables the OpenClaw AI agent to autonomously create cross-platform Kuikly apps by CLI-izing project setup, emitting structured JSON build errors, and feeding framework knowledge via Skills, producing working apps with real network requests while noting iOS compilation limits and the need for harness engineering.
Sogou Input Method shares its Kuikly cross-platform AI engineering practice, adopting Spec-Kit standardized workflow, GAN-inspired iterative context document generation, and Kuikly's built-in AI tools (MCP, Rules, Skills) to achieve 3x faster new page development (3 days → 1 day) with high code quality and minimal architectural rework.
Tencent's open-source Kuikly framework enables one Kotlin codebase to compile native apps for Android, iOS, HarmonyOS, Web, and mini-programs, serving 20+ products with 500M daily users; internal teams rate it 'multi, fast, dynamic, easy' citing 50% HarmonyOS efficiency gains, 22% iOS load improvement, 98% activity page arrival rate, and 60% development time reduction.
HelloTalk shares their experience adopting Kuikly, a Kotlin Multiplatform framework, for cross-platform development, detailing technical selection, native UI rendering, component extension, multi-language adaptation, modular architecture, and AI-assisted development workflow, achieving code reuse and efficiency gains.
Tencent's Kuikly cross-platform framework adds support for Apple's iOS 26 Liquid Glass design, demonstrating how native-rendering frameworks can directly leverage platform innovations while self-rendering frameworks like Flutter must simulate effects at higher cost and lower fidelity.
