Traffic Recording
Transparently proxy traffic to a real backend. APIKlone saves every successful response so you can instantly switch to offline mocking without missing a beat.
AI-Powered API Virtualization & Security
Deploy Mock Backends Reduce Costs with Semantic Cache Enforce AI Guard Rails Secure API Endpoints Virtualise Test Environments Unblock Frontend Development Achieve Testing Efficiency with APIKlone
Instantly mock, proxy, and replay backend traffic with built-in AI validation. Protect your systems from malicious prompts and drastically reduce LLM costs through intelligent vector caching.
How APIKlone Works
1. Create A Config
Create a APIKlone configuration for your backend. This will route all traffic to that host via APIKlone.
2. Proxy, Cache & Validate
APIKlone allows you to proxy traffic, intelligently cache AI responses, validate payloads, or act as a mock server.
3. Accelerate & Secure
Mock backends to unblock teams, save massive costs on LLM APIs with Semantic Caching, and secure endpoints with AI Guard Rails.
Rich, Developer-First Features
Built to accelerate your development lifecycle
OpenAPI Generation
Upload a Swagger 2.x or OpenAPI 3.x spec file and let APIKlone generate hundreds of endpoint routes populated with dynamic randomized mock data automatically.
Cloud Native
Stateless and entirely driven by Google Cloud Storage and Docker. Deploy APIKlone instantly to Google Cloud Run to provide shared staging environments for your entire team.
Polymorphic Keys
Route identical endpoints to completely different mock responses depending on deeply nested payload variables, mimicking complex backend business logic flawlessly.
Headless APIs
Manage your entire fleet of mocked routes strictly through our Headless REST API, enabling extreme scalability and seamless integration into CI/CD pipelines.
Built-in Security
Protect your admin dashboards through integrated local authenticated session management backed by mathematical PBKDF2 credential hashing.
NEW
Semantic Cache
Drastically reduce LLM and API costs by caching intelligent, semantically similar responses using vector embeddings.
NEW
AI Guard Rails
Ensure safe, reliable API behavior by enforcing AI-powered guardrails that block malicious prompts and validate responses in real-time.
