QA Wolf is a hybrid testing platform and managed service: AI agents map an app's workflows and generate Playwright and Appium tests for web, iOS, and Android, while a dedicated pod of human QA engineers writes, maintains, and triages them. Aimed at engineering teams that want full E2E coverage without staffing their own QA function.

Momentic is an AI-powered end-to-end testing platform that lets engineers write web and mobile UI tests in plain English, with an autonomous agent that interprets steps at runtime and locators that self-heal as the DOM changes. It targets engineering teams replacing Playwright, Cypress, or Selenium suites with low-maintenance coverage that runs in CI and as production canaries.

Greptile is an AI code reviewer that builds a graph index of your codebase and runs a swarm of agents on every pull request to catch bugs and style violations. Used by 9,000+ teams including Brex, Nvidia, PostHog, Klaviyo, Retool, and Zapier.
