Free AI Tools
Powerful AI tools you can use for free, including open-source projects and generous free tiers.
Deploying Local LLMs with Ollama
A cross-platform tool that lets you download and run open-source LLMs like Llama, Mistral, and Phi locally on your own machine. It provides a CLI, a local API server, and an OpenAI-compatible endpoint, so you can experiment with models privately — no GPU or cloud account required. Ideal for developers who want offline AI capabilities or need to test prompts before deploying to production.
Open WebUI
Open WebUI is a feature-rich, self-hosted AI chat interface that supports Ollama and OpenAI-compatible APIs out of the box. It runs fully offline, offers a polished multi-model conversation experience, and includes role management, markdown support, and plugin extensibility for teams and individuals.
Cline
Cline is an open-source autonomous coding agent for VS Code that can create and edit files, execute terminal commands, and browse the web — all with human approval at each step. It works with many model providers including Anthropic, OpenAI, and local models, giving developers full control over cost and privacy.
Aider
Aider is a lightweight, terminal-based AI pair programming tool that makes Git-aware edits across multiple files and commits changes automatically with sensible messages. It works with most popular LLMs, maps your entire repository for context, and suits developers who prefer staying in the command line.
LM Studio Local Model Client
LM Studio is a desktop application that lets you download and run open-source LLMs locally with a single click. It provides a polished graphical interface for chatting with models, an OpenAI-compatible local API server, and support for GGUF/GGML formats — no command line or GPU expertise required.
