## What it is
OpenDota is an open-source Dota 2 data platform that provides a REST API and web UI for match and player statistics. It ingests data from Valve's WebAPI and performs fully automated parsing of match replay (.dem) files using a Java-based parser.

## Use cases
- get dota 2 match statistics via api
- parse dota 2 replay files automatically
- self-host a dota 2 stats platform
- query player profiles and match history for dota 2
- build esports analytics tools on dota 2 data
- fetch hero and item data from dota 2

## When to choose
- you need programmatic access to Dota 2 match or player data
- you want to self-host the full data pipeline including replay parsing
- you're building analytics, dashboards, or bots on top of Dota 2 data

## When to avoid
- you need data for games other than Dota 2
- you want a turnkey hosted service without running PostgreSQL, Redis, and Cassandra yourself
- you can't obtain a Steam API key or a Steam account for replay parsing
