CodeWave SDD: NetEase's Controllable Enterprise-Grade AI Coding Platform

CodeWave SDD (official site: https://codewave.163.com/ ) is a controllable, enterprise-grade AI coding platform under NetEase Zhizhen. Built on NetEase's proprietary NASL domain language and spec-driven development, it replaces prompt guesswork with standardized processes, keeping the entire Prompt → Requirements → Design → Tasks → Code pipeline controllable, reviewable, and reversible. The platform unifies the tech stack, accumulates components and services as reusable enterprise assets, and can export standard Vue/React/Spring source code without vendor lock-in. CodeWave SDD has served leading enterprises including China Railway, BOE, and Industrial and Commercial Bank of China, helping them deliver digital transformation efficiently.

Main Features

• NASL domain-specific language: NetEase's proprietary web application description language. Its strong typing and static checks make AI-generated code visible and controllable, preventing architectural chaos and security vulnerabilities at the source.
• Visual programming: Drag-and-drop designers for pages, logic, data, and workflows let non-technical members participate in development and validation, greatly lowering maintenance barriers and communication costs.
• Dynamic retrieval and intelligent generation: Smart matching based on NASL constraints and enterprise assets lets AI recommend best practices within corporate standards, ending "black-box guessing".
• Spec-driven development: Standardized spec documents replace prompt guesswork, following the flow Prompt → Requirements → Design → Tasks → Code, with traceable results.
• Enterprise asset center: Centrally manages components, services, connectors, and other IT assets, supporting intelligent generation and reuse to break the "starting from scratch every time" dilemma.
• Legacy source reuse: Connects to existing corporate codebases and identifies common code, unlocking more use for legacy code and accelerating IT asset accumulation.
• Source code export: Exports Vue/React/Spring project templates with standard JS/Java source code, no vendor lock-in, meeting enterprises' autonomy and control requirements.

How to Use

1. Visit the official site (https://codewave.163.com/ ) to register and log in.
2. Clarify requirements: Describe business needs in natural language; the platform helps turn vague ideas into structured requirement documents.
3. Write the spec: Standardize requirements into a spec document, the single basis for subsequent AI generation.
4. Design confirmation: Build pages, logic, data, and workflows in the visual designer; solutions are reviewable and adjustable.
5. Task breakdown: The platform automatically decomposes the spec into a Design → Tasks development checklist for multi-role confirmation.
6. AI code generation: AI generates code based on NASL constraints and the enterprise asset library, with a traceable process and reversible results.
7. AI automated testing: AI tests its own generated code and automatically fixes and iterates on issues found.
8. Preview and delivery: Preview the interactive prototype online, then publish or export standard Vue/React/Spring source code for self-hosted deployment.

Core Strengths

• Controllable generation: NASL strong typing and static checks make AI output reviewable, reversible, and correctable.
• Standardized process: Spec-driven development replaces prompt guesswork, making the path from requirements to code fully standardized and traceable.
• Unified tech stack: Prevents architectural chaos at the source and the technical debt caused by AI improvisation.
• Asset accumulation and reuse: The asset center manages components, services, and connectors centrally; legacy code is identified and reused, so development speeds up over time.
• Low-barrier collaboration: Visual drag-and-drop design lets product managers and business operators join development and validation.
• Dual-mode editing: Freely switch between visual and code modes, balancing efficiency and flexibility.
• Autonomy and control: Export standard Vue/React/Spring source code to meet compliance and private deployment needs.
• Proven: Served China Railway, BOE, and Industrial and Commercial Bank of China, with verified outcomes of doubled workforce efficiency or nearly 2x profit improvement.

Use Cases

• Rapid delivery of internal enterprise systems: Mid- and back-office apps such as OA, CRM, and ERP peripheral systems — spec-driven development plus AI generation dramatically shortens the path from requirements to launch.
• High-compliance finance and government scenarios: Industries such as banking, tobacco, and state-owned enterprises with strict code security and autonomy requirements can use NASL static checks and source export for controlled delivery and private deployment.
• Legacy system modernization: Connect to existing codebases, identify and reuse common code, and gradually migrate old systems to a unified stack.
• Agile development with business participation: Visual drag-and-drop design lets product managers and business operators build and validate prototypes, cutting requirement communication overhead.
• University teaching and talent development: Partnering with over a hundred universities as a low-barrier AI development teaching platform, helping students quickly build complete applications and understand engineering workflows.

Limitations

CodeWave SDD targets enterprise scenarios; full capabilities such as the enterprise asset center and private deployment follow official business plans. Individual developers are advised to register on the official site for a trial first, then assess fit with team standards and compliance requirements.
