We present DAO Portal, a production-grade analytics pipeline and interactive dashboard for assessing the sustainability of Decentralised Autonomous Organisations (DAOs) through Key Performance Indicators (KPIs) derived from on-chain governance and token events. Building on our previous work, which defined and validated a multidimensional KPI framework for DAO sustainability, this paper moves from theory to practice by operationalising that framework in software infrastructure designed for finance and FinTech contexts. The system ingests governance and treasury data from major EVM networks, harmonises the outputs, and computes sustainability scores across four dimensions: participation, accumulated funds, voting efficiency, and decentralisation. A composite 0 to 12 score is then derived using transparent thresholds that are applied client-side in the browser. Using a curated snapshot of more than 50 active DAOs covering 6,930 proposals and 317,317 unique voting addresses, we show how the platform surfaces recurring patterns such as persistently low participation and concentration of proposal activity. These results demonstrate how DAO Portal supports the diagnosis of governance risks and the comparison of design choices across DAOs. To promote reproducibility and adoption, we release source code, data schema, and dashboard implementation. By turning governance traces into measurable and explainable KPIs, DAO Portal provides auditable evidence of DAO sustainability and contributes software engineering infrastructure for financial applications where treasuries and decision-making rights involve significant assets.
