What it does
SaaS companies lose thousands to trial abusers. Disposable emails. VPNs. Multiple accounts gaming your free tier. Vouch is an all-in-one tool that stops them. We combine email validation, device fingerprinting, and IP intelligence to detect fraud before it costs you. Catch disposable emails. Identify repeat offenders with device fingerprinting. Detect VPNs and proxies. Configure what to block, flag, or allow. Simple integration. Real-time verdicts. No more trial abuse.
Vouch stops trial abuse, fake signups, disposable emails, VPN fraud, and multi-accounting with email validation, device intelligence, and risk scoring.
One API validates emails, fingerprints devices, and blocks bad actors - p95 under 300ms. Ship fraud protection in minutes, not months. Every fake signup costs you money -- infrastructure, support, polluted analytics, and conversion rates that lie. Infra, support, polluted funnels, and subsidized abuse -- all preventable with a single API call. Competitors lurking inside your product, stealing your playbook. Vouch fuses email intelligence, device fingerprinting, and threat data into a single decision with p95 latency under 300ms. 160K+ disposable domains tracked. MX verification, catch-all detection, alias unmasking, role-account filtering, and real-time reputation scoring -- all in one…from vouch.expert

Hey HN! I wanted to share something I built over the last few weeks: isometric.nyc is a massive isometric pixel art map of NYC, built with nano banana and coding agents. I didn't write a single line of code. Of course no-code doesn't mean no-engineering. This project took a lot more manual labor than I'd hoped! I wrote a deep dive on the workflow and some thoughts about the future of AI coding and creativity: http://cannoneyed.com/projects/isometric-nyc
