OpenDota vs Scope.gg

OpenDota is a free, open-source Dota 2 data platform built around automated match-replay parsing. Its API supplies match, player, hero, team, league, ranking, live-game, and match-scenario data, including advanced details extracted from replays. The API works without a key; registering for one increases rate limits and usage. OpenDota says its raw data comes from Valve’s WebAPI and automated replay parsing. Professional and tournament matches continue to receive automatic parsing, and users can request manual parsing without a stated request limit. Subscribers receive automatic match parsing and a profile badge through the $5 a month OpenDota Subscriber plan. A mobile application uses the API on Android and iOS. OpenDota publishes its API code and Docker Compose instructions for self-hosting, with the core repository under the MIT license. The project began in August 2014, was founded by Howard Chung and Albert Cui, and directs support questions to its Discord community.

Scope.gg is a web service for analyzing Counter-Strike 2 matches and showing players their performance and areas to improve. Players can connect Steam or FACEIT match history for statistics, map insights, session summaries, and progress tracking. Tracked measures include ADR, HLTV Rating, KAST, kills per round, kill/death ratio, time to kill, headshot percentage, accuracy, and grenade usage. The service can capture and display standout clips, and a browser-based 2D demo viewer plays replays without launching the game or installing additional software. Uploaded matches remain stored indefinitely. A dashboard tracks skill changes every 15 matches and compares aim with Premier rating or FACEIT Elo. Scope Prematch analyzes opponents’ recent FACEIT matches, including likely positions, aggression zones, playstyle, and preferred weapons. Core access is free. Steam Premier, Competitive, and Wingman match uploads and analysis are free and unlimited; without a subscription, FACEIT users can analyze up to 10 matches per month, with five matches given at registration. SCOPE Lens costs $4.99 a month and adds unlimited match storage and analysis. There is no dedicated mobile app, though the mobile web version can be used on a phone.
