A tool to seed your dev database with real data
A bunch of developers and myself have created RepliByte - an open-source tool to seed a development database from a production database. Features: - Support data backup and restore for PostgreSQL, MySQL and MongoDB - Replace sensitive data with fake data - Works on large database (> 10GB) (read Design) - Database Subsetting: Scale down a production database to a more reasonable size - Start a local database with the prod data in a single command - On-the-fly data (de)compression (Zlib) - On-the-fly data de/encryption (AES-256) - Fully stateless (no server, no daemon) and lightweight…
In plain words
RepliByte is an open-source tool that helps developers seed local databases with production data for testing and development. It supports PostgreSQL, MySQL, and MongoDB, and can handle databases larger than 10GB. The tool automatically replaces sensitive data with fake alternatives, allows subsetting production databases to manageable sizes, and includes built-in compression and AES-256 encryption. It runs as a lightweight, stateless binary without requiring servers or daemons, enabling developers to start a local database with production-like data in a single command.

A bunch of developers and myself have created RepliByte - an open-source tool to seed a development database from a production database. Features: - Support data backup and restore for PostgreSQL, MySQL and MongoDB - Replace sensitive data with fake data - Works on large database (> 10GB) (read Design) - Database Subsetting: Scale down a production database to a more reasonable size - Start a local database with the prod data in a single command - On-the-fly data (de)compression (Zlib) - On-the-fly data de/encryption (AES-256) - Fully stateless (no server, no daemon) and lightweight binary - Use custom transformers My motivation: As a developer, creating a fake dataset for running tests is tedious. Plus, it does not reflect the real-world data and painful to keep updated. If you prefer to run your app tests with production data. Then RepliByte is for you as well. Available for MacOSX, Linux and Windows. > https://github.com/qovery/replibyte

Hi HN community, I’m Zach, founder and CEO of Warp, and am excited to show you Warp, a fast Rust-based terminal that’s easy to use and built for teams. As of today, Warp is in public beta and any Mac user can download it. It works with bash, zsh, and fish. The terminal’s teletype-like interface has made it hard for the CLI to thrive. After 20 years of programming, I still find it hard to copy a command’s output; I always forget how to use `tar`; and I always have to relearn how to move my cursor. To fix fundamental accessibility issues, I believe we need to start innovating on the terminal,…
