Local AI
Run AI models on your own computer: private, offline-capable and free to experiment with.
Ollama
The simplest way to download and run AI models on macOS, Windows and Linux, from one command.
- Best for
- First-time local AI users.
- Try this
- Run a small model and ask it the same question you would ask a cloud assistant, then compare the answers.
LM Studio
Download and run AI models on your computer through a desktop app. Useful for learning about local models and comparing them without writing code.
- Best for
- Beginners onward.
- Try this
- Compare two local models on the same writing or coding task. Hardware requirements vary by model.
Open WebUI
A self-hosted, browser-based interface for local and cloud AI models, with document and tool features.
- Best for
- Users comfortable with some setup.
- Try this
- Create a browser workspace for a model you already run locally. Self-hosting does not automatically make every connected service private.
llama.cpp
The engine behind the GGUF model format and many local AI tools, including the Q4, Q5 and Q8 quantization formats.
- Best for
- Builders who want fine control over local inference.
- Try this
- Run one model at two quantization levels and compare speed and answer quality.

One consistent API and an optional gateway for calling 100+ model providers, with fallbacks, spending limits and usage logging.
- Best for
- Ecosystems where several agents use different models.
- Try this
- Put it between your agents and the providers, then cap each agent's spending and add a fallback model in case a provider goes down.
OpenRouter
A hosted service that gives you one account and one API key for models from many providers.

- Trying and comparing many models without separate accounts.
- Try this
- Run the same prompt through three models and pick the best fit for each agent's job.
vLLM
A high-performance engine for serving open models on your own GPUs, with an OpenAI-compatible API.
- Best for
- Serving open models to several agents or users at once.
- Try this
- Serve one open model and point existing OpenAI-style code at it by changing only the address.
AI agents
Agent platforms that run on your own machine and connect AI models to your tools.
OpenClaw

Connecting and orchestrating agents
Standards and frameworks for connecting agents to tools and coordinating them as a system.
Model Context Protocol (MCP)
An open standard that lets AI applications connect to outside tools and data the same way every time. Build a connector (an "MCP server") once, and any assistant that supports MCP can use it.
- Best for
- Sharing one set of tools across all your agents and assistants.
- Try this
- Wrap one internal system, such as a database or a file share, as an MCP server and connect it to an assistant you already use.

CrewAI
A framework for teams of AI agents, each with a role, a goal and tasks, working together toward a shared result.
- Best for
- Prototyping role-based agent teams.
- Try this
- Set up a researcher, a writer and an editor agent and compare their combined output with a single agent's.
OpenAI Agents SDK
A lightweight Python framework for agents that hand tasks to each other, with built-in guardrails and tracing to see what each agent did.
- Best for
- Routing work between specialist agents.
- Try this
- Build a front-desk agent that routes requests to two specialists, then read the traces to see each decision. Model usage is paid.
Claude Agent SDK
Build your own agents on the same framework that powers Claude Code, including its agent loop, built-in tools and context management, in Python or TypeScript.
- Best for
- Specialized agents without building an agent framework yourself.
- Try this
