Hey Product Hunt! I'm Valentyn, a QA engineer from Ukraine.
I built MCatch because testing email flows in automated tests is painful. Whether it's signup confirmations, password resets, or any transactional email — you either mock it and miss real bugs, or use sleep() calls that make tests flaky.
MCatch solves this with: - Instant inbox creation via REST API - Retrieve full email content, parse HTML, check headers - Auto OTP extraction when you need verification codes - /wait endpoint with long polling — no more sleep() - Works with Playwright, Cypress, Python, Java, cURL
Free tier: 50 inboxes/month, forever, no credit card.
What email testing problems do you run into? I'd love to hear your feedback!
Simple and easy to use. I needed something lightweight for testing signup flows and password resets, and it works perfectly for that.
