PreisalarmTools

PreisalarmTools is a software toolkit designed to monitor prices across online marketplaces and to alert users when prices reach configurable conditions. It targets individual shoppers, procurement teams, and price-competitive businesses by providing a centralized view of price movements and deal opportunities.

The toolkit comprises a price-tracking engine, an alerting subsystem, and a presentation layer. The tracking engine collects price data from supported retailers via official APIs or, where permitted, respectful web scraping, normalizes data, and stores it in a time-series database. The alerting subsystem enables rules based on absolute price thresholds or percentage changes, with scheduling options and multiple notification channels (email, push, or SMS). The presentation layer offers dashboards and price-history charts, along with search and export capabilities.

Platform and deployment: PreisalarmTools is designed for modular deployment, with components that can be used together or independently. Common configurations include a web dashboard, browser extensions for page-level price capture, and mobile apps for on-the-go monitoring. The system supports multi-store aggregation and currency/locale handling, allowing users to compare prices across retailers.

Considerations: The project emphasizes data provenance, licensing, and compliance with retailer terms of service. Where possible, it favors official APIs and transparent data sources, and it implements rate limiting and user privacy protections to minimize impact on sources.

Status: PreisalarmTools is described in project documentation as a community-driven toolkit with ongoing development. Documentation and source code are typically provided under an open-source license.
