Insomnia vs Testfully

Insomnia is an API collaboration platform for designing, testing, debugging, mocking, and governing APIs. Its client supports HTTP, REST, gRPC, GraphQL, WebSockets, SOAP, and SSE. Design workflows include OpenAPI spec-first work, live previews, and generation of collections, tests, and mocks. Mocks can be generated from collections, OpenAPI specifications, API responses, or natural-language descriptions, locally or in the cloud. The collection runner supports unlimited runs, JavaScript before-request and after-response scripts, chained requests, and CI/CD execution through Inso CLI. Insomnia also connects to HTTP and STDIO MCP servers, supports custom tool parameters, and provides MCP authentication event logs. API data can stay local, reside in a Git repository, or be stored in Insomnia Cloud with optional end-to-end encryption. Teams can share projects, collections, mocks, and design specifications with organization controls and real-time collaboration indicators. Essentials is free; Pro is $12 a month per user, and Enterprise is $45 a month per user. It supports Linux, macOS, Windows, and self-hosted use.

Testfully is an API testing and monitoring platform with web, desktop and browser extension options. Its client supports RESTful, GraphQL and XML APIs, with cloud or local offline storage. Testing tools include no-code response validation, contract testing, request chaining, folder runners and scripts; the CLI can run tests in CI/CD pipelines. Users can import data from Postman or Insomnia, and the product supports OpenAPI Specification.

Monitoring can reuse workspace requests, retain a history of runs and send alerts through email, SMS, Slack or PagerDuty. Teams can assign roles and control folder access. The free Developer Edition includes core features and commercial use, one offline and one cloud workspace, and up to five invited users per workspace. Offline workspaces can be used without an account. Team Edition costs $14 a month per user when billed annually; Enterprise Edition costs $29 a month per user when billed annually. Paid plans have a 14-day free trial enabled by contacting sales. Desktop apps support macOS 12 or later, Windows 10 or later (64-bit), and Ubuntu 20+ and compatible Linux distributions. Browser extensions are listed for Chrome, Firefox and Microsoft Edge; Safari is marked as coming soon. Testfully says it was made in Australia and is headquartered in Sydney.
