About SanityCheck
SanityCheck uses AI agents to automate quality assurance testing of web applications. Users provide a URL and a plain-language description of the test scenario, such as adding an item to a cart or verifying an order confirmation. The platform then spins up real browsers in the cloud to execute these tasks as a human user would, without requiring any test code, SDKs, or CI configuration. Each test run produces a live view of the session, a forensic replay with time-synced actions, console output, network requests, and video, along with a plain-English report of observations. The system enforces security constraints by encrypting credentials and applying hard limits on domains, steps, and time per run. Tests can be triggered manually or automatically on every deployment via GitHub, GitLab, or Vercel integrations. The platform is designed for solo founders and small teams who need QA coverage without maintaining test infrastructure or writing test scripts.

Frequently asked questions about SanityCheck
What is SanityCheck and how does it work?
SanityCheck uses AI agents to automate quality assurance testing of web applications. Users provide a URL and a plain-language description of the test scenario, such as adding an item to a cart. The platform then spins up real browsers in the cloud to execute these tasks as a human user would, without requiring any test code, SDKs, or CI configuration.
Who is SanityCheck designed for?
The platform is designed for solo founders and small teams who need QA coverage without maintaining test infrastructure or writing test scripts. It aims to provide the QA engineer experience for teams that typically lack dedicated QA resources.
How do I get started with SanityCheck?
To get started, provide a URL of your web application and describe the test scenario in plain language. No test code, SDKs, or CI configuration are required. You can then run the test manually or set it up to trigger automatically on deployments via GitHub, GitLab, or Vercel integrations.
Does SanityCheck support CI/CD integrations?
Yes, SanityCheck supports CI/CD integrations with GitHub, GitLab, and Vercel. Tests can be triggered automatically on every deployment, allowing teams to verify their applications as soon as they go live.
How secure are the credentials used in SanityCheck?
Credentials are encrypted and never provided to the AI agent. The platform uses AES-256-GCM encryption and enforces hard limits on domains, steps, and time per run to ensure security. Agents log in without ever reading the secret credentials.
What kind of evidence and reports does SanityCheck provide after a test run?
Each test run produces a live view of the session, a forensic replay with time-synced actions, console output, network requests, and video, along with a plain-English report of observations. This provides a comprehensive view of what happened during the test.
