How BulkMaker actually works
We're upfront about this because most "bulk" tools online quietly fall back to simulated or client-only results once you look closely.
Server-side where it matters
Checking another site's tags, links, redirects or certificate requires connecting to that site, a browser can't do this across domains. BulkMaker's PHP backend makes the real request and parses the real response. Domain dates come straight from the registry over RDAP and WHOIS.
No account, no stored data
Nothing you paste is saved to a database. Results exist for your request and your download; we don't build a profile of what you've checked. Even QR codes are encoded on our server instead of being sent to a third-party API.
Built by one developer
BulkMaker isn't a venture-backed SaaS. It's maintained by a single developer who uses these tools daily, if something's wrong, tell us and it gets fixed.
