New: Kopi v0.2.4 is live on NuGet

Replicate your production schema locally in seconds.

Stop restoring 500GB backups just to fix a bug. Kopi extracts your production schema and fills it with a clean, anonymized slice of data. Get a fully functional local database running in Docker in a few seconds.

How Kopi Works

Turn your massive production database into a lightweight development asset in three steps.

01

Define your Slice

Create a simple kopi.json file. Point it at your source DB and define the "seed" tables (e.g. Orders, Sales).

02

Extract & Anonymize

Kopi connects in Read-Only mode to analyze your schema and extract only the relevant data. Sensitive PII is automatically anonymized in real-time without modifying your source.

03

Spin Up

Kopi launches a local Docker container pre-filled with your clean data (and your entire source DB schema). You get a connection string, ready for coding in seconds.

Why developers love Kopi

Bridge the gap between security compliance and development velocity.

Instant Subsets

Shrink terabytes into megabytes. Define a slice (e.g., "100 users") and Kopi automatically grabs all related rows across your entire schema.

Smart Anonymization

PII never hits your laptop. Kopi replaces sensitive fields with realistic data (via Bogus) before the data leaves the secure zone.

Declarative Config

Infrastructure as Code for your data. Commit a simple kopi.json file to your repo so every dev gets the exact same dataset.

Security First

Read-Only. Always.

Your security team will love this: Kopi will only ever execute SELECT statements on your source database.
