Key Differences
🏗️ Architecture Approach
Libraesva Email Archiver is deployed as a virtual appliance - a self-contained system image that runs as a VM.
Piler uses a microservices architecture with Docker containers or native packages. Scale components independently, update without full system replacement.
🤖 AI Capabilities
Libraesva focuses on traditional archiving features with keyword-based search.
Piler Enterprise includes semantic search (find by meaning) and Smart Insights for automatic sensitive data detection - all running on-premise.
🔧 Infrastructure Flexibility
Virtual appliances typically include all components bundled together. Integration with existing infrastructure can be limited.
Piler lets you use your own MySQL/MariaDB cluster, Redis, and search infrastructure. Integrate with existing monitoring and backup systems.
