Zunoy MockAPI is mainly useful for teams that need APIs for development or testing before the real backend is ready. Instead of waiting for the actual API, users can create mock endpoints and use them in their frontend work, QA testing, or internal demos. It lets users define responses, status codes, headers, query params, auth, and other request details based on what they want to test. Different scenarios can also be added for the same endpoint, so it becomes easier to check how an app behaves in different cases. For example, a team can test success and error responses without changing the real API. Another useful part is that Zunoy MockAPI also gives API docs and request logs, so teams can see how the mock APIs are being used and share the details easily with others. Overall, it helps reduce waiting time during development and makes it easier for frontend and testing work to continue even if backend APIs are not available yet.

AISIX AI Gateway is API7.ai’s Rust-native gateway for LLM and AI-agent traffic. The Apache-2.0 open-source gateway runs as a standalone data plane in the customer’s infrastructure and provides an OpenAI-compatible API, model aliases, provider credential isolation, routing and failover, access control, rate limits, caching, guardrails, and observability. Teams can run the gateway independently or optionally use AISIX Cloud, API7.ai’s commercial control plane, for centralized gateway configuration, organizations and roles, managed credential lifecycles, request logs, usage and cost visibility, budgets, and audit history. Live AI requests travel directly through AISIX gateways and do not pass through the control plane. The open-source gateway can be self-hosted for free. AISIX Cloud adds managed Developer, Team, and Enterprise options for organizations that need shared administration and governance across environments. Customers connect their own model-provider accounts and pay providers directly; AISIX is an AI gateway rather than an LLM relay or token reseller. Feature availability, support, deployment, and service levels depend on the selected AISIX Cloud plan.
