Software Architecture Guide

purpose

This is a comprehensive guide to software architecture concepts, covering definitions of architecture, why it matters, application boundaries, microservices, and legacy displacement patterns. It serves as a hub linking to deeper articles and resources about architectural thinking.

when to use

This resource is most valuable when starting new projects, planning major refactoring efforts, or transitioning from monolithic to microservices architectures. It's also useful when developers are transitioning into architectural roles or need to justify architectural decisions to stakeholders.

turnstonelabs/turnstone

purpose

Turnstone is a local-first orchestration system that gives LLMs access to tools (shell, files, search, web, MCP servers) and coordinates multi-turn conversations where AI agents investigate, take actions, and report results across your own infrastructure.

when to use

Use Turnstone when you need to build AI agent workflows that require tool usage, privacy-sensitive data handling, or multi-node scaling—particularly when you must keep all data on infrastructure you control. It's ideal for automating DevOps tasks, building internal AI assistants, or creating autonomous agent pipelines.

SQL to ER Diagram

purpose

SQL to ER Diagram converts SQL CREATE TABLE statements into interactive entity-relationship diagrams directly in the browser, displaying tables, columns, primary keys, foreign keys, and relationships. It supports PostgreSQL, MySQL, SQLite, and SQL Server syntax and allows export to PNG or SVG.

when to use

This resource is most valuable when designing a new database, documenting an existing schema for team onboarding, or reviewing database structure before implementation. It's also useful when preparing technical documentation or communicating data models to non-technical stakeholders.

presenton/presenton: Open-Source AI Presentation Generator and API (Gamma, Beautiful AI, Decktopus Alternative)

purpose

Presenton is an open-source AI presentation generator that creates professional presentations from text prompts or uploaded documents, supporting multiple AI model providers and offering both a desktop application and a deployable API service. It allows users to generate, edit, and export presentations as PPTX or PDF while maintaining full control over their data and models.

when to use

Presenton is most valuable when developers need to programmatically generate presentations, build presentation features into their applications, or require a self-hosted alternative to commercial AI presentation tools like Gamma or Beautiful AI. It's ideal for teams wanting data privacy, cost control through BYOK (Bring Your Own Key), or the ability to use local models via Ollama.

opentabs-dev/opentabs: Browser automation clicks buttons. OpenTabs calls APIs.

purpose

OpenTabs is a CLI tool paired with a Chrome extension that bridges AI agents to web APIs using the user's authenticated browser session. It provides 100+ pre-built plugins covering ~2,000 tools for services like Slack, GitHub, Stripe, and AWS, while also supporting custom plugin development.

when to use

This tool is most valuable when you need AI assistants to perform actions on web services where you already have an authenticated session, without dealing with API key management or OAuth flows. It's ideal for automating multi-service workflows, building AI agents that interact with SaaS platforms, or rapid prototyping of integrations.

tamnd/kage: Shadow any website for offline viewing, with the JavaScript stripped out

purpose

Kage clones websites into local folders by rendering each page in headless Chrome, snapshotting the settled DOM, stripping all JavaScript, and downloading CSS, images, and fonts to local paths. It can also pack mirrors into single ZIM archives or self-contained executable files for easy sharing and long-term storage.

when to use

Kage is most valuable when you need permanent offline copies of content-heavy sites, want to verify how a site behaves without JavaScript, or need to archive web content for long-term preservation. It's also useful for creating portable, self-contained site bundles for distribution or viewing in environments without network access.
