MockLab
Craft your simulation using the friendly, no-code UI or go fully automated with the 100% WireMock-compatible API. Simulate stateful behaviour in your mocked API using a simple finite state machine model. Test your app to destruction by injecting delays, dropped connections, drip-drip responses and corrupt HTTP payloads. A MockLab plan's collaborator limit is the total number of individual collaborators + team members that can be added by the owning account so e.g. if your subscription has a collaborator limit of 2, this means that you and 2 colleagues can work on your APIs. Test your app to destruction by injecting delays, dropped connections, drip-drip responses and corrupt HTTP payloads.

Blackbird API Development
Accelerate Development of Prod-Ready APIs.
AI-Powered Code Gen, Mocking in Minutes, and On-Demand Ephemeral Test Environments.
* Design Efficiently: Generate standardized OpenAPI specs with AI assistance, allowing you to begin coding faster.
* Mock Effortlessly: Create shareable API mocks without manual coding, enabling rapid validation.
* Automate Repetitive Tasks: Utilize AI to automatically generate boilerplate code for both client and server-side APIs.
* Test Effectively: Access publicly available URLs for testing in a production-like test environment through Blackbird's ephemeral testing environments.
* Debug Seamlessly: Set breakpoints and debug directly from your preferred IDE with Blackbird's integrated debugging tools.
* Deploy Smoothly: Utilize a 24/7 hosted environment for progressive and repeated testing without reconfiguration, facilitated by Blackbird's containerized deployment.

Speedscale
AI bug repair from real production traffic, run entirely in your cloud. Speedscale captures HTTP, gRPC, and SQL traffic via eBPF inside your Kubernetes cluster. Production payloads never leave your perimeter.
When a failure occurs: the capture agent records the exact request, a triage agent classifies it, a reproduction agent replays it against your codebase, and a validation agent verifies the fix before the PR opens. Fully autonomous or human-gated.
You supply the cloud, storage, and AI models (Anthropic, Llama, or your own). Speedscale orchestrates the loop with no cloud, model, or storage lock-in.
proxymock: free CLI giving AI coding agents (Claude Code, Cursor, Copilot) real production context via MCP. No signup required.
Meets PCI and HIPAA data-residency requirements. Used by Home Depot, IHG, FLYR, Cimpress/Vistaprint, Navitaire, and Ascension Health.

Specmatic
Specmatic offers a no-code, specification-driven, visual approach to API testing by leveraging API specifications to automatically execute positive and negative tests. Specmatic Studio offers broad format and protocol support across REST, SOAP, GraphQL, gRPC, WebSockets, and asynchronous messaging systems (message queues and event-driven APIs).
The platform provides a comprehensive toolkit for API development and testing, utilizing specs as the single source of truth.
Key features include:
• Contract testing across various protocols
• Service virtualization and mocking
• Workflow and resiliency testing
• Backward compatibility checks to prevent breaking changes
• Open-source testing tools for OpenAPI, MCP and SOAP
• Postman collection import for spec creation
Specmatic focuses on functional correctness, contract compliance, resiliency, and compatibility testing.
Genie assists API design, enabling interactive validation of the API spec prior to generating an MCP server.
