Mastra is a TypeScript framework designed to help build AI applications.

Features:

• LLM Models: Uses the Vercel AI SDK for model routing, offering a unified interface to interact with LLM providers such as OpenAI, Anthropic, and Google Gemini. Allows selection of specific models and providers, with the option to stream responses.

• Agents: Systems where the language model determines a sequence of actions. In Mastra, agents equip LLM models with tools, workflows, and synchronized data. They can access knowledge bases and call functions or third-party APIs.

• Tools: Typed functions that can be executed by agents or workflows, featuring built-in integration access and parameter validation. Each tool includes a schema defining inputs, an executor function implementing its logic, and access to configured integrations.

• Workflows: Durable, graph-based state machines that support loops, branching, waiting for human input, embedding other workflows, error handling, retries, and parsing. They can be built in code or with a visual editor, and each step has built-in OpenTelemetry tracing.

• RAG (Retrieval-Augmented Generation): Enables the construction of knowledge bases for agents through an ETL pipeline that includes chunking, embedding, and vector search.

• Integrations: Auto-generated, type-safe API clients for third-party services that can be used as tools for agents or steps in workflows.

• Evals: Automated tests that evaluate LLM outputs using model-graded, rule-based, and statistical methods, providing a normalized score between 0-1 for logging and comparison. Evals can be customized with user-defined prompts and scoring functions.

Mastra can be run locally or deployed to a serverless cloud. To start using Mastra, you'll need Node.js (v20.0+) and an API key from an LLM provider like OpenAI, Anthropic, or Google Gemini. You can quickly start a new Mastra application using the create-mastra CLI tool.

The Kirby Staticache Plugin enhances the performance of Kirby installations by providing static site generation capabilities.

Features:

• Static Site Performance: It delivers the performance benefits of a static site generator without requiring complex setups or deployment steps.

• Versatile Hosting: Kirby sites can run on various servers, including cheap shared hosting and VPS, while utilizing static cache for speed.

• Custom Ignore Rules: Allows mixing static and dynamic content by configuring ignore rules, enabling specific pages to remain dynamic while others are statically cached.

• Automatic Cache Flushing: The static cache is automatically cleared whenever content is updated in the Panel.

• Cache Configuration: Staticache can be activated as a cache driver for pages. Ignore rules can be configured to keep specific pages dynamic.

• Custom Cache Comment: Adds an HTML comment to cached HTML files, which can be customized or disabled.

• Custom Root: The cache root can be overridden for custom web server setups. Disabling the root URL prefix is possible for single-domain sites.

• Web Server Integration: Requires web server configuration (Apache, Caddy, nginx) to prioritize static cache files over dynamic PHP results. A PHP loader can be used if server configuration access is unavailable, though it is slower than direct web server integration.

• Header Support: The plugin can be configured to store HTTP status codes and headers if the web server supports reading headers from static files.

• Limitations: A statically cached page will prevent any Kirby logic from executing, so pages with logic in controllers, page models, templates, snippets, or plugins that result in different page responses depending on the request are not compatible with Staticache.
