Develop Without Waiting

No more waiting for backend APIs to be ready. Create mocks for endpoints that don't exist yet and keep your development flowing.

Eliminates development bottlenecks

Test Edge Cases

Easily simulate loading states, error responses, and network failures to ensure your UI handles all scenarios gracefully.

Improves application resilience

Team Collaboration

Share mock configurations with your team to ensure everyone is working with consistent API responses.

Enhances team productivity

Zero Code Changes

No conditional logic or mock providers cluttering your codebase. Your API calls remain clean and production-ready.

Maintains clean architecture

Rapid Prototyping

Create and modify API responses on the fly. Experiment with different data structures without backend coordination.

Accelerates design iterations

GraphQL Migration

Gradually transition from REST to GraphQL by adding fields and operations before they're implemented on the server.

Simplifies API transitions
Product Roadmap

What's Coming to MockQL

Our development roadmap is shaped by your feedback. Here's what we're building next.

Q2 2025: Schema Inference

In Development

Automatically generate mock data from your existing API schemas. MockQL will analyze your GraphQL or OpenAPI specs to create realistic test data that matches your production environment.

Q2 2025: Role-Based Authentication & Access

Planned

Implement granular access control with customizable user roles and permissions. Define who can view, edit, or manage specific mock APIs, projects, and team settings. Perfect for organizations with diverse teams and security requirements.

Q3 2025: Collaborative Workspaces

Planning

Work together with your team in shared workspaces. Create, edit, and manage mock APIs collaboratively with version control, comments, and approval workflows.

Q4 2025: Multi-Environment Support

Research

Configure different mock behaviors for development, staging, and production environments. Seamlessly transition between environments with environment-specific variables and configurations.

Q1 2026: Enterprise Security Features

Research

Advanced security features for enterprise customers including SSO integration, role-based access control, audit logs, and compliance reporting for regulated industries.

AI-Powered Mock Generation

Coming Q2 2025

Generate realistic mock data using AI. Our advanced machine learning models will create contextually appropriate test data based on your API structure and field names.

AIMachine Learning

Advanced Scripting

Coming Q3 2025

Write custom JavaScript functions to create dynamic mock responses. Simulate complex business logic, generate calculated fields, and create realistic data relationships.

Frequently Asked Questions

Everything you need to know about using MockQL

MockQL integrates with your development workflow as a standalone service that intercepts and mocks API requests. Simply configure your frontend to point to MockQL's endpoints during development. There's no need to install browser extensions or npm packages - MockQL works as an API proxy that responds with your configured mock data, making it framework-agnostic and requiring zero changes to your application code.

Yes! MockQL is designed to work with both REST and GraphQL APIs. It can intercept, modify, and simulate responses for any HTTP request, regardless of the API architecture. This makes it perfect for modern applications that might use a combination of both approaches.

MockQL allows you to create highly accurate API simulations based on your API specifications or sample responses. You can define exact schemas for GraphQL or JSON structures for REST, and even simulate various edge cases, loading states, and error conditions to thoroughly test your frontend.

MockQL gives you complete control over response timing, allowing you to simulate real-world network conditions or test how your UI handles slow responses. You can also inject custom errors with specific status codes and messages to ensure your error handling is robust.

Yes, MockQL is built with teams in mind. You can share mock configurations, create environment-specific settings, and even sync your mocks with version control. This ensures everyone on your team is working with the same API expectations, regardless of backend availability.

MockQL scales from individual developers to enterprise teams. Our tiered pricing model ensures that teams of any size can benefit from faster frontend development without unnecessary overhead. For enterprise users, we offer additional features like SSO, audit logs, and dedicated support.
