DumbPipe
Unix pipes let you chain commands by sending one program's output as another's input. DumbPipe extends this concept across the internet, creating pipes between computers without accounts or configuration. Run one command on each machine to stream data directly between them, solving the problem of transferring data when SSH access or file sharing services aren't available.
The tool wraps the Iroh connection layer in 200 lines of Rust, finding direct connections where possible and falling back to relay servers for roughly 10-20% of connections that can't connect directly. DumbPipe serves as both a standalone utility and example implementation for building network pipes into applications.
Rails Lens
https://github.com/seuros/rails_lens
Rails Lens provides structured model annotations and ERD generation for Rails applications. The tool analyzes database schemas and generates machine-readable annotations directly in model files, including foreign keys, polymorphic associations, STI hierarchies, and performance recommendations. Supports PostgreSQL, MySQL, and SQLite3 with database-specific features like check constraints and generated columns.
The structured format eliminates guesswork when working with LLMs or searching codebases. Rails Lens also detects common extensions like ClosureTree and PostGIS, generates Mermaid ERDs, and provides route annotations for controllers. Installation requires Ruby 3.4+ and Rails 7.2+.
Sidequest.js
Sidequest.js is a distributed background job processor for Node.js supporting PostgreSQL, MySQL, SQLite, and MongoDB backends. Uses worker threads for non-blocking job processing with configurable retry policies, job scheduling, and uniqueness constraints. Includes a web dashboard for monitoring jobs and queues.
Created by the maintainer of node-cron to solve issues with running background jobs inside Express apps. Works with existing database infrastructure without vendor lock-in. Supports both ESM and CommonJS with full TypeScript integration and provides CLI tools for database management.
