I Built a Mini Palantir Foundry-Style Platform in FastAPI and
Next.js.
An open-source, self-hosted data platform inspired by Palantir Foundry
The Challenge
Modern data stacks are powerful, but often fragmented. Teams use separate tools for ingestion, transformations, dashboards, notebooks, permissions, AI, workflows, and operations. Each tool may work well alone, but the gaps between them create serious problems: permissions drift, lineage becomes incomplete, data gets copied, governance is inconsistent, and AI can accidentally bypass security controls. Mini Foundry was built to explore a compact Foundry-style alternative: one self-hosted platform where data can be connected, cataloged, governed, queried, transformed, modeled as business objects, used in dashboards and applications, assisted by AI, and audited through one shared backend permission and resource model. The challenge was not simply building individual features like a CSV uploader, SQL editor, dashboard builder, notebook, or job queue. The harder challenge was making sure every feature obeys the same governance rules at execution time.
Bottleneck Analysis
Identification of relay failures in distributed nodes.
The Solution
Advanced Core Logic
One place to connect data, govern it, transform it, model it as business objects, and build analytics or operational apps on top.
