Alidade is an open-source Web-GIS platform where maps are represented as single JSON documents, enabling features like deep undo history and layer persistence across basemap changes. It includes PostGIS vector tiles, satellite imagery, 3D models, and a real-time asset layer, with no API key requirements. The architecture separates the core model from renderers (MapLibre, three.js), allowing flexible replacement of components.
PlanLint is an open-source AEC compliance checker that uses LLMs only for entity recognition and text parsing, while delegating all compliance verdicts to deterministic Python logic grounded in actual CAD geometry and codebook rules. The system models compliance as a bipartite graph in Neo4j, ingesting architectural drawings through specialized pipelines for different sheet types and applying rule-based verification to prevent AI hallucinations that could pass non-compliant designs.
FastAPI-Crons is a Python library that enables cron job scheduling directly within FastAPI applications using decorators, eliminating the need for separate worker processes. It supports async/sync functions, retries, timeouts, distributed locking, and persistent state management via multiple backends.
Weftgate is a local CLI tool that verifies code connections written by AI agents, catching errors like typos in environment variables, missing imports, and broken route handlers before deployment. It runs offline without API keys or runtime dependencies and integrates with agents, GitHub Actions, and MCP servers.
A FastAPI service that analyzes League of Legends in-game screenshots and voice questions to provide audio coaching advice. It uses configurable LLM providers (Gemini or Grok), OpenAI Whisper for transcription, and OpenAI TTS for speech synthesis.
