Projects on this term

The score comes from our model.

• Show HN: Paganel – Data migration with a receipt you can verify later · score 7.3

  Paganel is a Rust-based data migration engine that moves data and schema between MySQL, PostgreSQL, and CSV with declarative pipelines, crash-safe resume, parallel execution, and cryptographic Merkle-tree receipts for row-level verification. It combines schema/data migration, in-flight transforms, dry-run planning, and verifiable integrity in one binary, filling a gap between ad-hoc dump/restore and heavyweight ETL platforms.

• Show HN: Open-source AAS digital twin studio with live PLC data collection · score 7.0

  VEXPLOR AAS Studio is an open-source web application for authoring, validating, and serving Asset Administration Shell (AAS) models, with the unique ability to collect live data from PLCs and publish it via OPC UA. It combines editing, linting with 52 rules, auto-fix, and data collection from industrial protocols (OPC UA, Modbus, S7, MELSEC, XGT) into a single tool, aiming to simplify AAS adoption in factories. The project is technically ambitious and well-documented, but its niche focus on AAS and industrial integration limits broader appeal.

• Show HN: CLI for your financial data (and Costco and Amazon) · score 7.0

  fin is a CLI tool that unifies personal financial data from multiple banks, brokerages, Amazon, and Costco into a single interface, with JSON output designed for AI agent consumption. It leverages Plaid for account and transaction data and provides rich features like Amazon item-level categorization, holdings with cost basis, and DuckDB integration for querying. The project is notable for its clean UX and explicit focus on agent-readable outputs, making it a bridge between personal finance and LLM-driven workflows.

• Show HN: Transit – subway maps of your data · score 6.8

  Transit is a local toolkit of Agent Skills that converts traces, CI runs, and coding-agent sessions into animated subway-map visualizations. It supports multiple data sources like OTLP, Datadog, and AWS X-Ray, and produces interactive HTML pages, GIFs, or MP4s that make performance bottlenecks and failures easy to spot. The novel metaphor and shareable outputs make it a creative approach to observability.
