SDKGPT
SDKGPT is a mobile app SDK intelligence platform. It crawls app stores for APKs, parses SDK signals (.so/Service/Activity/DEX), matches against LibChecker knowledge base, and outputs SDK intelligence. Covering 1,900+ SDKs, 57000+ DEX package signals, 280K+ Android apps, 1,100+ companies.
SDKGPT helps SDK vendors find customers, investors do market analysis, and security researchers batch-audit apps. Browsing data is permanently free; combo exploration for leads, full market share, and export are paid B2B features.
Core Data
- SDK Rules：1,900+
- DEX Package Signals：57000+
- Android Apps：280K+
- Companies：1,100+
Data Pipeline (5 Stages)
- 1. Crawl App Stores：Huawei + Tencent MyApp stores, resumable crawling + keyword auto-expansion
- 2. Download APK：aria2c multi-threaded download, resumable
- 3. Parse APK：androguard parses .so/DEX/Service/Activity signals, subprocess isolation prevents OOM (one fresh subprocess per APK, RLIMIT_AS 8GB hard limit)
- 4. Match SDK Rules：Matches using LibChecker original logic (== || startsWith(prefix+".")), covering .so/DEX/Service/Activity four signal types
- 5. Output SDK Intelligence：Write to database, frontend display + API queries
SDK Signal Types
- .so Signal (signal_type=0)：Native library filename (e.g. libBaiduMap.so). Shallow layer extracts filename, deep layer uses pyelftools to extract JNI function names and internal strings from .so binary
- DEX Package Signal (signal_type=1)：Java/Kotlin package name prefix (e.g. com.umeng.analytics). 57000+ package signals covered
- Service/Activity Declaration (signal_type=2)：Service and Activity component names declared in AndroidManifest.xml
- URL Signal (signal_type=10)：http/https URL hosts extracted from DEX strings (e.g. ulogs.umeng.com). Used to discover pure REST API integrations, cloud services/SaaS without SDK package name traces
SDK Matching Rules
- Package Name Match：== (exact match) or startsWith(prefix+".") (prefix + dot, not simple startsWith)
- .so Match：Filename exact match or prefix match
- Service/Activity Match：Component name exact match or prefix match
- URL Match：Host suffix match sdk_company.domain
Matching results have two levels: confirmed signal (rule-matched, is_confirmed=true) and potential signal (not yet matched, is_confirmed=false, upgraded after LLM final judgment).
