## What it is
PoloDB is an embedded document database written in Rust that stores BSON documents with a MongoDB-like API, backed by RocksDB storage. It can be used as an embedded Rust library or run as a standalone server with partial MongoDB wire protocol compatibility.

## Use cases
- embed a document database in a Rust desktop or mobile app
- store schemaless JSON-like data locally without a database server
- replace SQLite when a document data model fits better
- run a lightweight MongoDB-compatible local server
- persist app data with transactions and indexes offline-first

## When to avoid
- you need full MongoDB feature parity or production-grade MongoDB compatibility
- you need a single portable database file rather than a RocksDB directory
- you require battle-tested maturity for critical production workloads

## Facets
- artifact type: library
- maturity: active
- function: database, serialization
- domain: databases, developer-tools, cross-platform
- platform: rust, cross-platform, windows, python
- tags: embedded-database, document-database, nosql, local-first, mongodb-like, bson, rocksdb, localfirst, macos, linux, android, ios
