FastAPI framework, high performance, easy to learn, fast to code, ready for production

1,324-exercise fitness dataset — animation GIFs, 180×180 thumbnails, muscle-group & equipment data, and step-by-step instructions in 6 languages. The exercise data layer behind the LogPress app.

The Model Context Protocol (MCP) connects LLMs to tools and data. FastMCP is a full MCP application framework for servers, clients, and interactive apps. A server starts with ordinary Python:

SQL databases in Python, designed for simplicity, compatibility, and robustness.

WebLLM is a high-performance in-browser LLM inference engine that brings language model inference directly onto web browsers with hardware acceleration. Everything runs inside the browser with no server support and is accelerated with WebGPU.

TypeLLM brings type-safe generation to existing autoregressive LLMs without changing their architecture or weights. Inspired by TypeSafe AI's Jev, it lets models retain their native thinking and free-form generation while producing schema-guaranteed outputs through JSON Schema.

The OpenAPI Specification is a community-driven open specification within the OpenAPI Initiative, a Linux Foundation Collaborative Project.

A simple React component capable of using JSON Schema to declaratively build and customize web forms.

Your continuing support is very important - the funds will be used to develop and maintain Ajv once the next major version is released.

JSON Hero is an open-source, beautiful JSON explorer for the web that lets you browse, search and navigate your JSON files at speed. 🚀. dev team.

Our managed platform runs improved extraction with higher accuracy than the open weights, plus per-field verification, citations, and confidence scores.

Generate types and converters from JSON, Schema, and GraphQL

In React, the whole tree rendering performance problem of the form is very obvious in the controlled mode. Especially for the scene of data linkage, it is easy to cause the page to be stuck.

1207 public resources for Jev, TypeSafe AI's System One decision model, indexed by decision pattern. Source citations, dated link checks and scheduled call-site text checks; runtime and performance are not independently tested here. EN/中文, JSON schema and platform compatibility.

A model-agnostic, stateless Go agent runtime featuring dual-IR planning, dependency-aware batch scheduling, capability-driven MCP/tool orchestration, policy-based failure recovery, conditional replanning, side-effect control, and end-to-end execution observability.
