All-in-one LLM CLI written in Rust that gives unified access to 20+ AI providers (OpenAI, Claude, Gemini, Ollama, Groq, Mistral, DeepSeek, and more) through one terminal interface. Includes a shell assistant, interactive REPL with session management, RAG over local files and URLs, custom roles, function calling, and a built-in HTTP server exposing Chat Completions, Embeddings, and Rerank APIs plus an LLM Playground and Arena for model comparison.

Free and 100% open source under dual MIT/Apache-2.0 licenses. Rust-based all-in-one CLI with no software costs; uses BYOK for 20+ commercial LLM providers (OpenAI, Claude, Gemini, DeepSeek) and supports 100% free local models via Ollama.

ShellGPT

open sourceexplicit relation

ShellGPT (sgpt) is a command-line productivity tool powered by OpenAI models that generates shell commands, code snippets, and documentation directly in the terminal. Integrates with Bash, Zsh, PowerShell, and CMD; places AI-suggested commands into the terminal input via hotkeys. Supports persistent chat sessions, a REPL mode, and custom Python functions for extending capabilities. Accepts stdin and arguments for pipe-based workflows where command output can be piped to the AI.

Free and 100% open source under the MIT License. Software is completely free; operates via Bring-Your-Own-Key (BYOK) for OpenAI/Anthropic or 100% free local models via Ollama and OpenAI-compatible endpoints.

Aider

83/100open sourceexplicit relation

Terminal-based AI pair programmer with deep git integration. Auto-commits changes with meaningful messages and creates repository maps for navigating large codebases. Works with Claude, GPT, DeepSeek, and local models. One of the most popular open-source AI coding tools, known for its reliability, broad model support, and seamless command-line workflow.

Aider is free, open-source CLI software (Apache 2.0) with zero subscription fees ($0). Users bring their own API keys from providers like Anthropic, OpenAI, or DeepSeek and pay standard token rates directly to those providers, or connect free local models via Ollama.Review →

Claude CodeAnthropic's agentic CLI coding tool that delegates complex tasks to Claude directly from the terminal. Understands entire codebases via automatic context gathering, edits multiple files, runs shell commands, and manages Git workflows autonomously. Supports CLAUDE.md for persistent project instructions, integrates with VS Code and JetBrains, and uses Claude Opus/Sonnet with extended thinking for complex architectural decisions. Built for terminal-first developers.AmpAmp is a multi-model coding agent for terminal, web, macOS/iOS, and IDE-connected workflows. Vendor docs describe the same agent and threads across surfaces, with remote Orbs, local Runners, Dial modes (low / medium / high / ultra), shared threads, MCP, plugins, and BYOK / linked ChatGPT subscriptions. Pricing spans a free Hobby tier, optional Megawatt ($20/mo) and Gigawatt ($200/mo) Individual plans, no-extra-charge Teams workspaces, pay-as-you-go credits, and Enterprise.CodexCodex is OpenAI's coding agent for software development across the Codex app, editor, terminal, and cloud tasks. It helps write, review, debug, refactor, and automate code, with ChatGPT plan access for managed surfaces and API-key usage for CLI, SDK, and IDE workflows. The open-source CLI and SDK support local repository work, while cloud features add GitHub review, Slack/Linear integrations, worktrees, skills, MCP, and automations.ripgrepUltra-fast recursive text search tool written in Rust that respects .gitignore rules automatically. Searches directories significantly faster than grep with smart defaults like line numbers, syntax highlighting, and compressed file support. The de facto replacement for grep among developers, combining the speed of Rust with sensible defaults that eliminate the need for complex command-line flags.GitDiagramVisual architecture generator that transforms any GitHub repository into an interactive system design map within seconds. Analyzes repository structures and README documentation to produce validated component flowcharts, dependency graphs, and Mermaid diagrams. Supports direct URL routing by replacing hub with diagram, provides instant export to SVG and PNG formats, and handles private repositories through user-supplied personal access tokens.GStackGStack transforms Claude Code into a structured virtual engineering team through 23 opinionated slash command skills created by Y Combinator CEO Garry Tan. It assigns specialist roles including CEO product review, engineering manager architecture oversight, designer visual audit, QA lead with real browser testing, and release engineer deployment. Each skill enforces focused workflows with clear decision principles for running parallel coding sessions.Oh My ClaudeCodeOh My ClaudeCode (OMC) is a plugin for Claude Code that adds multi-agent orchestration with 19 specialized agents, smart model routing between Haiku and Opus, and execution modes such as Autopilot, Team, Ralph, Ultrawork, and Deep Interview. It provides lifecycle hooks, a real-time HUD statusline, and source-backed Claude Code workflows that turn one session into a coordinated AI development team.Hermes AgentHermes Agent is an open-source AI agent framework with persistent memory, reusable skills, 40+ tools, cron jobs, and messaging gateways.RepomixRepomix packages entire repositories into single AI-optimized files for feeding to LLMs like Claude, ChatGPT, and Gemini.
