MoaV is a multi-protocol Internet censorship circumvention stack optimized for hostile network environments. It deploys via Docker Compose and runs over sixteen protocols, including VLESS, WireGuard, and DNS tunnels.

AcadGIS is a Python package and no-code web app designed to generate publication-ready study area and thematic maps without needing QGIS or ArcGIS. It automates boundary downloads, fuzzy name matching, and choropleth plotting. "Everything runs through a single import acadgis as agis."

Context.dev provides a unified web data API for AI agents and RAG pipelines, replacing custom scraping infrastructure. It enables developers to crawl sites, convert pages to LLM-ready markdown, and extract structured data into a defined JSON schema.

Apache Ossie is an open-source specification standardizing semantic metadata exchange across analytics, AI, and BI platforms. It provides a vendor-neutral single source of truth to eliminate metric drift.

ClickHouse RayTracer is a path tracer written entirely as ClickHouse SQL queries that renders directly to a PNG. It uses no UDFs or external code, meaning "a single SELECT computes every pixel." The renderer parallelizes work across CPU cores by representing pixels as rows and using arrayFold for

This reference implementation demonstrates a production-shaped data pipeline running on a single 35-euro-per-month virtual server. It uses Dagster, dlt, and dbt to ingest open data into a DuckDB medallion architecture.

OrionBelt Analytics is an MCP server that generates RDF/OWL ontologies with SQL mappings to enable relationship-aware Text-to-SQL. It uses OBQC for deterministic validation to catch fan-traps and join errors.

Dash is a self-learning data agent using systems engineering to ground answers in six context layers. It automates SaaS metrics analysis like MRR and churn trends. It grounds answers in 6 layers of context and improves with every query. The stack includes Docker, OpenAI, and the AgentOS UI.

GitBiased enables data engineers to build customizable GitHub dashboards. It integrates live pull requests, CI checks, and DORA metrics. The tool focuses on providing weekly summaries and calm visibility into engineering workflows without the noise of standard notification systems.

StreamFusion accelerates Apache Flink SQL by executing operators natively via Rust and DataFusion over JNI. It targets stateful streaming tasks like windowed joins and changelog processing.

Allemannsdata provides Model Context Protocol servers wrapping Norwegian public data, including transport, energy, and registries. Engineers can access live AIS ship tracks, ENTSO-E grid metrics, and SPARQL endpoints for the national data catalog via streamable-http transport.

origin-mcp is a local Model Context Protocol server enabling AI assistants to automate OriginPro on Windows. It uses the originpro Python package to bridge LLMs with scientific data workflows. origin-mcp is a local Model Context Protocol (MCP) server that lets AI assistants control Origin/OriginPro.

TiDB is an open-source, cloud-native distributed SQL database featuring horizontal scalability and ACID compliance. It separates computing from storage, using the Raft consensus protocol for high availability.

Claude's dbt connector enables direct interaction with data projects to browse lineage, query metrics, and trigger jobs. It allows engineers to investigate model health and performance by identifying failed tests or slow builds. This integration helps teams answer questions from your data faster.

SQLRooms is an open-source React toolkit for building data-centric apps using client-side DuckDB. It enables fast in browser data processing without a backend by leveraging OPFS for persistent storage. Engineers can build modular, privacy-focused analytics tools with AI agent integration.
