Gptme

Provider-agnostic terminal AI agent with shell, Python, file and browser tools

7.5 /10

Pricing: Open source

Pros

Model-agnostic (Anthropic, OpenAI, Google, xAI, DeepSeek, OpenRouter, local llama.cpp) rather than locked to one vendor
Mature and actively maintained: MIT, ~4.4k stars, 4,500+ commits, recent v0.33.0 release (Aug 2026) adding sandboxed execution
Broad tool set out of the box: shell, Python REPL, incremental file patching, browser automation, vision, plus a plugin/skills/hooks system

Cons

Executes arbitrary shell and Python commands on your machine at the model's direction — real risk if run unsupervised without its guardrail features enabled
Autonomous/persistent-agent mode needs careful configuration (task selectors, pre-commit checks) to use safely
