Released	2023-02	2023
Pros	Fully open source (MIT license) with no vendor lock-in Visual builder reduces boilerplate while allowing full Python customization Extensive pre-built component library for major LLMs, databases, and APIs Deploy as API, MCP server, or JSON export for flexible integration Active development and enterprise backing (IBM/DataStax)	Fully open-source and self-hosted with no vendor lock-in No external databases or cloud services required Agentic multi-step task automation with Pochi agent Support for multiple popular IDEs and code editors End-to-end stack optimization for fast completions under 1 second
Cons	Requires infrastructure management and DevOps knowledge for production deployment Steeper learning curve than some competing low-code platforms for non-technical users Cost complexity due to dependency on external services (LLM APIs, cloud hosting, vector databases)	Requires infrastructure management and GPU resources for optimal performance Agent (Pochi) is in private preview, not fully released to general availability Steeper setup complexity compared to cloud-based alternatives
