Thanks. The project is built mainly to solve my own problem that I often receive requests from the business side that they wanna access the data in the production system (We use different RDMS and Elasticsearch) so they can generate some simple charts in Excel and display to the customers. The request is not difficult but we just don't have a system for that. Since then, I have been trying different BI solutions like Power BI, Kibana and some other open source tools. They are either too complicated to setup/use or the license/fee is not friendly enough to me. That's why I build Poli. I want it to be more focusing on easy to use, having an open license and the developer can use SQL to build reports easily for the end users or embed the reports in their systems.
