How To: Safely Anonymize Production Data In Laravel
In almost every company I’ve worked with, there’s a moment when someone asks:
“Can we get a copy of production data for staging or local debugging?”
And almost every time, that question is followed by hesitation.
Production data is valuable — but it’s also dangerous.
It contains emails, names, phone numbers, IDs, and other sensitive information that shouldn’t casually move around.
Yet teams still need realistic data to:
- debug real-world issues
- test edge cases
- reproduce bugs
- validate migrations
- support QA and external reviews
This tension is what led me to build Veil.
The problem with most “solutions”
In practice, I’ve seen teams handle this in a few common (and risky) ways:
- writing one-off SQL scripts to mask data
- manually editing dumps
- partially anonymizing only obvious columns
- copying production data and “hoping for the best”
These approaches are:
- error-prone
- inconsistent
- hard to repeat
- easy to forget or misconfigure
And once data leaks, you can’t undo it.
What I wanted instead
I wanted a solution that was:
- repeatable — the same anonymization rules every time
- configuration-driven — no ad-hoc scripts
- safe by default — sensitive columns are explicitly handled
- usable in real workflows — not just demos
Most importantly, I wanted something teams could trust when exporting production-like data.
Introducing Veil
It’s designed for scenarios like:
- creating staging databases
- sharing data with developers or contractors
- debugging production issues locally
- preparing datasets for testing or QA
Instead of modifying data manually, you define anonymization rules per table and column. Veil then applies those rules consistently during export.
Under the hood, Veil builds on top of spatie/laravel-db-snapshots and phpmyadmin/sql-parser, and adds a focused anonymization layer on top.
The goal is simple: keep your data useful without exposing what shouldn’t be exposed.
Why I open-sourced it
This isn’t a theoretical problem, it’s something I’ve encountered repeatedly — across companies and teams.
Rather than solving it privately again, I decided to open-source Veil so:
- other teams don’t have to reinvent the same scripts
- the solution can be reviewed and improved
- the workflow stays transparent and predictable
Open source felt like the right place for this kind of tooling.
Where Veil fits long-term
Veil is now maintained under the SignDeck GitHub organization — alongside other open-source tools we use internally.
SignDeck itself is a lightweight platform for collecting documents and signatures, where handling sensitive data responsibly is a core concern. Veil grew out of that same mindset: treat production data with care, even when you need to work with it.
Sounds familiar?
If you’ve ever:
- needed production-like data for debugging
- worried about leaking sensitive information
- written masking scripts you didn’t fully trust
Veil might be useful for you.

Final note
This post isn’t about tools for the sake of tools. It’s about acknowledging that data safety and developer productivity don’t have to be at odds — if the right abstractions exist.
Veil is my attempt at one of those abstractions.
