Zunoy Sandbox is a developer sandbox testing platform for safely testing email, SMS, webhooks, and OTP or TOTP-based 2FA workflows without reaching real users or affecting production systems. It captures application-generated messages and events in an isolated workspace, making it suitable for development, staging, quality assurance, and CI/CD testing.
The platform lets teams inspect email HTML, headers, attachments, delivery data, and links; review SMS content and OTP flows; examine webhook payloads in real time; and generate time-based authentication codes for MFA testing. Developers can connect existing SMTP clients, SMS SDKs, REST APIs, or webhook endpoints without changing providers or rewriting application code. Zunoy Sandbox also supports event logs, filtering, replayable webhook requests, shared team access, and notifications through collaboration tools such as Slack, Discord, Microsoft Teams, and Telegram. It is available for integrations using Node.js, Python, PHP, Java, Ruby, Go, and other technologies.
