Dev environments that match production. Exactly.
Everyone knows the line: it works on my machine. Here, every dev setup is an exact copy of production.
Environment differences cause production bugs
The test setup never quite matches the real one. Different OS. Different settings. Different data. So the code passes every test, then breaks the moment real users hit it. Those bugs hide for days. They cost real money. And they only exist because dev and production don't match.

What environment mismatch really costs
Every production bug caused by environment drift is a bug that should never have existed.
One command. Perfect parity.
Copy
Start from an exact copy of production. Same OS, same settings, same data. The copy is instant and takes almost no extra disk space.
Develop
Build and test against real production data. Every setting, every file, every row of data is identical.
Deploy
Ship with confidence. No surprises. What works in the copy works in production.
A rough guess vs. an exact copy
Most dev setups are rough guesses, built by hand, configured separately, and filled with fake test data. Rediacc copies the real production system instead, right down to the disk.
A rough guess vs. an exact copy
| Traditional Dev Setup | Rediacc |
|---|---|
| Manually install OS packages, hope versions match | Exact OS, packages, and versions copied from production |
| Fake test data that doesn’t match real usage | Real production data copied with zero extra storage |
| Settings drift over days, weeks, months | A fresh copy every time, so nothing can drift |
| Days to set up, with no proof it matches | 47 seconds, with an automatic parity check (--verify-parity) |
| A staging cluster built from the same YAML still drifts from prod | rdc cluster fork copies the running cluster, data included. 46 seconds in our lab |
What it includes
Exact match
OS, libraries, settings, Docker config, and real production data. All identical. We verify it automatically.
No drift
Each copy starts fresh from the latest production state. So the gap between dev and prod isn't just smaller. It can't happen at all.
Fewer production bugs
When dev and prod match exactly, setup bugs stop happening. Not fewer of them. Zero.

Most developer tools copy the code. Rediacc copies the whole running system. That means code, data, settings, and services together.
