Own the email validation platform. Run it anywhere.
The complete source code of MXGuard — a production-grade email validation platform. Launch it as your own SaaS, self-host it for your team, or deploy white-label for your clients.
Launch your own SaaS
Brand it, price it, list it. Every line of code is yours to modify and sell.
Self-host for your team
Bring email validation in-house. Deploy next to your stack. No per-lookup fees.
Deploy for clients
White-label the portal. Host on client infrastructure. Serve your customers end-to-end.
Three things you stop doing on day one.
Paying per validation.
No metered API. No credit top-ups. Validate a million emails or a billion — infrastructure is your only cost.
Waiting on a vendor.
No roadmap votes, no support queue. Need a feature? Open the file and ship it the same day.
Renting your stack.
The code lives on servers you control, under your brand, with no phone-home. Yours outright.
Built for three kinds of buyer.
Founders launching SaaS
Skip the six months you’d spend rebuilding this. Launch an email validation SaaS with a codebase already running in production.
Agencies serving clients
White-label the portal for your clients. Host on their infrastructure, charge what you charge — no per-seat fees, no “powered by” branding.
Teams going in-house
Stop paying per-lookup. Self-host next to your stack, integrate with your auth, own the data path end-to-end.
What changes on day one.
Your per-check cost goes to zero.
Volume stops mattering. Validate a million emails a month or a billion — the only cost is your own infrastructure.
Ship what you want. Today.
No feature requests, no waiting for a roadmap. The code is on your laptop — change anything, ship anything.
Three ways to run it.
One codebase, three business models. Use it yourself, white-label for clients, or combine both under one brand.
Your brand. Your domain. Your data.
Rebrand the portal. Host it anywhere. Every email that passes through stays on servers you control — no phone-home, no telemetry, no external dependencies.
The product you’ll own.
The same portal running at 0bounce.email. Dark navy and teal, built for validation at scale.
Everything that runs the live product.
The same codebase powering MXGuard today. Nothing held back.
Frontend portal
React 18 + TypeScript, Tailwind, 40+ production components.
Validation engine
11-point SMTP / MX / DNS signal stack with concurrent probe pool.
Supabase schema
Postgres schema with Row-Level Security audited across every table.
Payments integration
Webhook handlers, credit ledger, license delivery, refund logic.
Deploy kit
Docker Compose, Hetzner Terraform template, SMTP node bootstrapper.
80-page handbook
Architecture, deploy runbook, SMTP tuning notes, scaling playbook.
“We used the MXGuard engine to launch 0bounce.email. Went from concept to validating a million emails a day in under three weeks. The SMTP stack alone would have taken our team three months to build from scratch — and honestly, ours would have been worse.”
