Test email flows locally, without risking real inboxes
InboxTap is a powerful open-source SMTP capture server designed for developers and QA teams to test email flows locally without risking real inboxes. It provides a secure and isolated environment where email messages—such as signup verifications, password resets, OTPs, and invitations—are captured and accessible within the local testing environment. By running it on localhost, developers can simulate email delivery, verify link accuracy, and validate code content seamlessly, all without external delivery or spam concerns. Its compatibility with popular testing frameworks like Playwright, Vitest, Jest, Bun, and Node 20+ makes it a flexible choice for modern development stacks. Unique in its approach, each test run is isolated, ensuring parallel testing does not cause message mixing, which enhances test reliability and consistency.
