The score comes from our model.

• Show HN: Dánwò – Open-source E2E testing with emulators and fault injection · score 7.5

  Dánwò is a TypeScript-based end-to-end testing framework for web and mobile apps that combines UI testing (via locators or cached plain-English agent steps) with backend emulation of third-party providers (Stripe, Clerk, Resend, etc.) and a fault matrix for verifying invariants under injected failures. Its novel backend-aware testing and recording/replay agent steps address a real gap in E2E tooling, and it integrates with Playwright, Cypress, Detox, and CI/coding agents.

• Show HN: E2E – Open-source agentic testing framework for web, iOS and Android · score 7.5

  e2e is an open-source agentic testing framework that lets developers describe test goals in natural language, which an AI agent then executes against web, iOS, and Android apps. It combines AI-driven actions with traditional locators and assertions, and records agent actions for deterministic replay on subsequent runs. This hybrid approach makes end-to-end testing more accessible and resilient to UI changes.

• Show HN: Pseudogress – high performance PostgreSQL mock for testing · score 7.3

  Pseudogress is a high-performance PostgreSQL mock server written in Rust that simulates many virtual databases for load-testing PostgreSQL clients, especially multi-tenant PostgREST. It records real database responses and replays them with configurable latency and faults, allowing thousands of connections without a real database. The project uses a class-based configuration, records time-aware data, and provides a Nix-based build.

• Show HN: Mcpward – contract and security testing for MCP servers in CI · score 7.3

  MCPward is a contract and security testing tool for MCP servers, designed to run in CI pipelines. It snapshots server contracts (tool schemas, descriptions, annotations) and detects drift, flagging breaking changes, security issues like tool poisoning, and protocol violations. It fills a gap in MCP tooling by treating servers as dependencies with enforceable contracts.
