Development tools and libraries for agent systems
GPT Engineer is an AI tool that generates entire codebases based on natural language descriptions. Just describe what you want to build, the AI asks for clarification, and then builds it.
LiteLLM provides a unified interface and proxy gateway for LLM calls, simplifying multi-model switching, routing, and cost control.
browser-use enables browser automation for agents, allowing LLMs to understand pages and perform complex web interactions.
DeepEval is an open-source evaluation framework for LLM applications. It provides rich evaluation metrics and tools, supporting unit testing and integration testing to help developers build reliable LLM applications.
Continue is an open-source AI code assistant extension for VS Code and JetBrains IDE. It can autocomplete code, refactor, and explain code, helping developers improve programming efficiency.
Graphiti is a temporal knowledge-graph engine for agent memory, helping systems continuously accumulate long-term context.
Helicone is an open-source proxy and observability platform for LLM applications, offering request tracing, caching, and cost analytics.
smolagents is a lightweight agent framework from Hugging Face for quickly building tool-using LLM agents.
Letta (formerly MemGPT) is an open-source framework for building stateful AI agents with advanced reasoning and transparent long-term memory. It allows you to visually test, debug, and observe agents.
Mem0 is a long-term memory layer for AI agents, supporting cross-session memory management and personalized context retrieval.
MCP Servers provides a large collection of reusable Model Context Protocol server implementations, giving agents standardized tool capabilities.
Aider is an AI coding assistant that lets you pair program with LLMs in your terminal. It supports Git integration and can automatically commit code changes, perfect for developer pair programming.
