Best for a free terminal coding agent

Open Interpreter is an Apache-2.0 terminal coding agent that works with whichever model you connect, including local ones, plus a separate desktop app. The terminal agent is free; the desktop app's price is not stated.

Who Open Interpreter is for

  • Fits if you work in a terminal and want to pick your own model
  • Works for people who want a coding agent that can run on a local model

Who Open Interpreter is not for

  • Skip it if you want a phone or web app, as it runs on computers only
  • Not for you if you avoid the command line, since the terminal agent lives there
  • Tight if you need a stated price for the desktop app, because the pages read give none
  • Watch out: hosted models receive your instructions and file excerpts, and only a local profile keeps everything on the machine

Why Open Interpreter gets a 2.8

Five grades, each with its reason. The GPA is their average: an A is 4 points, an F is none.

  • AValue for moneyThe terminal agent is free under Apache-2.0. You pay your model provider, or nothing with a local model.
  • AFree plan and trialInstall it and run it with no plan, no cap and no account, apart from model costs. The desktop app's price is not stated.
  • BFeaturesA terminal agent with sandboxed commands, model switching, editor compatibility and local models, plus a desktop app for files and browser tabs. No gap shows in the core job.
  • DEase of useNo rating on record. The terminal agent runs from a command line and needs model keys set up.
  • CPlatforms and integrationsRuns on Mac, Windows and Linux only. No phone, web or hosted version.

Keep Open Interpreter, or make your own?

Keep it

Open Interpreter is free, so making your own would save you nothing.

And it is not the kind of software a weekend replaces. It is one of the better ones too: its GPA of 2.8 is higher than 160 of the 178 other AI agents we grade.

What you could not

  • An AI agent, with the models and the safeguards behind it.
  • Apps for macOS, Windows and Linux that stay in step with each other.
  • It plugs into other products, OpenAI, OpenRouter and Ollama among them, and has an API.
  • What a company asks for before it lets staff use something: roles and permissions.
  • The depth: we grade its features B, which means it covers the whole job.

What this rests on. Open Interpreter’s listing: what it does, where it runs, what it plugs into and what it costs. It is a judgement about the kind of software this is. We have not built a replacement for it, and making your own means looking after it too. How we decide, and every tool’s verdict.

What is Open Interpreter?

Open Interpreter is a terminal coding agent released under the Apache-2.0 license, built as a fork of OpenAI's Codex and tuned to work with lower-cost and open models. A separate desktop app, called Interpreter, drives local apps, files and browser tabs for office-style work. Both connect to whichever model provider the user configures, including local models.

Worth knowing

  • Model costs are paid to whichever provider is connected; the vendor's pages list no hosted plan.
  • No price for the desktop app is stated on the pages read, so only the open-source terminal agent is recorded as free.
  • Neither the terminal agent nor the desktop app is listed for iOS or Android, and neither runs as a hosted web app.
  • Hosted models receive the instructions and the file excerpts the agent needs; only a local profile keeps everything on the machine.

Key features

Harness emulation
The /harness command switches between agent harnesses such as native, claude-code, kimi-code, qwen-code and swe-agent, aimed at getting better results from low-cost models.
Provider and model switching
The /model command picks a provider and model from the terminal. The docs cover Kimi, DeepSeek, Z.AI and Google AI Studio, and any OpenAI-compatible provider can be used through Chat Completions.
Sandboxed command execution
Commands run inside native sandboxing on macOS, Linux and Windows, with permissions and approval settings.
Editor and SDK compatibility
Runs as an Agent Client Protocol agent for compatible editors, and speaks the Codex exec protocol so the Codex SDK can point at it.
Desktop app for cross-app work
The Interpreter desktop app opens apps, reads files in a chosen workspace, runs web tasks and takes voice instructions, pausing for review before it submits, sends, deletes or overwrites.
Local models and MCP
Profiles can point at Ollama or LM Studio for local-only use, and MCP servers and skills extend what the agent can reach.
