Coding agent (CLI) · Open Interpreter
Open Interpreter
Terminal coding agent, a Rust fork of OpenAI's Codex CLI tuned for cheap open-weight models. Can imitate other agents' harnesses, runs commands in OS-level sandboxes, and works with ACP editors and the Codex exec protocol.
Open Interpreter review
Open Interpreter is now a terminal coding agent written in Rust, forked from OpenAI's Codex CLI. It is free and Apache-2.0 licensed. We read the vendor's pages and repository in October 2026. We did not run an independent test.
This is not the older Python project of the same name. That one lives on as a community fork under AGPL-3.0. Version numbers of the new agent are still 0.0.x.
Who it is for
Developers who want a Codex-style terminal agent they can point at cheap or local open models, with sandboxing on.
What stands out
Install with the shell script from openinterpreter.com, or the PowerShell script on Windows. It is a native binary for macOS, Linux and Windows, and WSL is documented too.
`interpreter exec` runs non-interactively, with JSON event output, output schemas and a CI recipe. Commands run in an OS-level sandbox: Seatbelt on macOS, bubblewrap and seccomp on Linux, and a native one on Windows. It reads AGENTS.md, `.agents/skills`, MCP and ACP.
Providers include OpenAI, Amazon Bedrock, Ollama and LM Studio, with a catalog of 100-plus hosted providers.
Price and licence
The LICENSE file is Apache-2.0, so this is open source. The NOTICE credits OpenAI Codex. The CLI is free to install, seen 28 October 2026. We found no hosted plan or pricing in the docs (we did not review the site's Desktop App). Model cost comes from your own keys, a subscription such as Kimi Code, or free local models.
Where it falls short
- The 0.0.x versions and young codebase mean behaviour may change. It differs from the well-known Python tool.
- The GitHub star count carries over from the old Python project in the renamed repository, so it says little about this agent.
- You set up model access yourself; there is no hosted option.
- Much of the interface and protocol comes from Codex rather than being new.
Alternatives
See terminal coding agents. The parent project is Codex CLI. OpenCode is another open-source choice.
Facts: platforms, price and licence
- platforms
- macOSLinuxWindowsNative Rust binary installed by script (macOS/Linux shell, Windows PowerShell); WSL also documented. This is the 2026 Rust rewrite forked from OpenAI's Codex CLI, not the original Python project, which now lives on as a community fork (endolith/open-interpreter, AGPL-3.0). Version numbers are still 0.0.x.
- price
- FreeThe CLI is free to install (seen 2026-10-28). No hosted plan, pricing page or free-tier terms found in the docs. Model cost comes entirely from the provider you connect (your own API keys, a subscription such as Kimi Code, or free local models via Ollama/LM Studio). The site also has a 'Desktop App' product that was not reviewed.

Open Interpreter strengths
- Apache-2.0 licence confirmed in the repo's LICENSE file, with a native sandbox on macOS (Seatbelt), Linux (bubblewrap/seccomp) and Windows
- Documented non-interactive 'interpreter exec' mode with JSON event output, output schemas and a CI recipe
- Works with local runtimes (Ollama, LM Studio) and 100+ hosted providers through your own keys
- Reads shared standards (AGENTS.md, .agents/skills, MCP, ACP), so config is portable to other agents
Open Interpreter weak points
- Early version numbers (0.0.x) and a young codebase; behaviour differs from the well-known original Python Open Interpreter
- Star count shown on GitHub is inherited from the old Python project in the same renamed repo, so it does not measure the new agent's adoption
- Docs focus on open-weight models and a few providers; no hosted option or pricing, so you must set up your own model access
- Derived from Codex, so much of the interface and protocol is shared with that project rather than original
Who Open Interpreter is for
- best for
- Developers who want a Codex-style terminal agent they can point at cheap or local open models with sandboxing on.
- look elsewhere if
- Anyone looking for the old Python 'let the model run code on my computer' tool or a ready-to-pay hosted service.
