Built for developers, governed by enterprise IT
Use tools such as OpenCode, Claude Code, PI or other development clients while keeping source code protected.
Full software lifecycle
Generate code, refactor, debug, document, create tests, review architecture and migrate frameworks.
Ultra-low latency
Optimized for low time-to-first-token and high throughput so developers stay in flow.
IP protection
Customer source code is not used for model training - for core products with local/EU models. With European infrastructure and governance controls, ZDev keeps your code protected.

Enterprise AI Coding. Built for speed.
ZDev is Zeldoc's private enterprise coding model, engineered specifically for professional software development. It runs on dedicated European infrastructure, and combines frontier-class reasoning, exceptional coding performance and multimodal understanding with ultra-low latency, giving developers an AI assistant that feels both faster and more capable than traditional coding assistants.
Designed for modern software engineering, ZDev supports everything from code generation and debugging to large-scale refactoring, architecture guidance and repository-wide reasoning. Its large context windows allow developers to work across entire applications rather than isolated files, making it ideal for complex enterprise projects.
Speed and performance. ZDev runs on dedicated European infrastructure optimized for coding workloads, delivering lower latency and faster time-to-first-token than public frontier models. Developers get instant responses without queues or rate limits from shared capacity.
No throttling. Unlike frontier model providers that throttle usage, ZDev has no hard rate limits. Under fair usage the worst case is simply slower response times if a developer overspends - developers are never blocked or cut off.
Unlimited usage and fair usage. The Max plan offers unlimited usage with no per-token billing, so developers can focus on building software rather than tracking spend. Lower plans include generous fair usage with predictable flat-rate pricing. The Go plan includes agent credits per month, Pro includes 3x agent credits per month, and Max includes unlimited usage under fair usage. For Pro, token usage exceeding included amounts is billed as passthrough at cost - see pricing and Terms for details.
Free trial. Organisations can request a free trial to experience ZDev's speed, context and unlimited usage firsthand before committing to a plan.
Running exclusively on Zeldoc's European AI Platform, ZDev ensures full GDPR compliance, Zero Data Retention and complete protection of your source code and intellectual property - for core products with local/EU models. When routing to external frontier models via ZRouter, data leaves the EU at inference and Zero Data Retention cannot be guaranteed. Developers can use tools such as OpenCode, Claude Code, PI or other development clients while keeping source code protected.
