Cypress vs Insomnia

Cypress is a front-end testing tool for web applications, combining an open-source Cypress App with the cloud-based Cypress Cloud service. The App supports end-to-end and component testing, launching and controlling real browsers from Chrome-family browsers and Firefox; WebKit is experimental. For debugging, it offers time-travel snapshots, readable errors, stack traces, automatic waiting, and network stubbing. Cypress Cloud stores recorded CI test runs and adds debugging, analytics, and orchestration for teams. It connects with GitHub, GitLab, Bitbucket, Slack, Microsoft Teams, and Jira, and its MCP works with AI coding assistants including Claude, Cursor, and GitHub Copilot. The Starter plan costs nothing and includes 10 users, 500 test results per month, 100 prompt executions per month, and 30-day access to paid features. Team costs $67 a month, billed annually at $799. Cypress says Cloud test content is stored in the United States, and material in public projects is publicly accessible. It also says its AI models are not trained on customer data.

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.
