This repository provides a lookup table comparing internal Facebook technologies and services with their open-source and commercial equivalents. It's designed for former Facebook employees transitioning to new environments or for anyone seeking to understand the landscape of similar tools. The primary benefit is to bridge knowledge gaps by mapping familiar internal systems to external alternatives.

How It Works

The project is structured as a Markdown table, listing internal Facebook technologies in one column and their open-source/real-world or cloud/commercial counterparts in adjacent columns. This direct comparison format allows for quick identification of analogous tools, facilitating easier adoption of external technologies. The data is curated by individuals with direct experience at Facebook.

Quick Start & Requirements

• View the lookup table directly in the GitHub repository's README file.
• No installation or specific software requirements are necessary to access the information.

Highlighted Details

• Comprehensive mapping of over 40 internal Facebook technologies.
• Includes comparisons for areas like data processing (FBLearner Flow vs. TFX/Metaflow), messaging (FOQS/Iris vs. Kafka/Pulsar), and version control (Mercurial -> Git).
• Notes on specific features or limitations of certain external tools are provided.
• Identifies commercial SaaS alternatives where applicable.

Maintenance & Community

• The project is maintained by former Facebook employees.
• No explicit community channels or roadmap are linked in the README.

Licensing & Compatibility

• The repository does not specify a license.
• Compatibility for commercial use is not explicitly stated.

Limitations & Caveats

The table is a snapshot and may not reflect the latest internal or external technology updates. Some entries lack detailed explanations or direct equivalents, relying on user interpretation. The project's scope is limited to technologies familiar to ex-Facebook employees.
