AsoBeast is App Store Optimization software for app developers, studios, agencies and marketers who publish on the Apple App Store and Google Play. After a store link is added, the platform imports the listing, tracks its keywords once a day down to position 200 in up to 175 App Store and 225 Google Play countries, and keeps a year of daily ranking history. It discovers competitors from live search results, detects changes to their titles, icons, screenshots and versions, and measures how rankings moved 7, 14 and 28 days after each listing update. Reviews and ratings are synced and mined for keyword ideas. An Action Center applies 15 rules to this history and produces a task list ordered by estimated impact, with the supporting data attached to every task. Other features include keyword research with popularity and difficulty scores, an ASO audit that scores listings out of 100, alerts by email, Slack, Discord or webhook, CSV and JSON export, a REST API and a read-only MCP server for AI assistants. AsoBeast is open source under AGPL-3.0 and is available as a hosted service or for self-hosting with Docker.
