Gemini API code execution alternatives
The 5 alternatives below are grouped by kind of sandbox, and each says what it does differently from Gemini API code execution. Start from whatever made you look: missing GPUs, session limits, self-hosting, pricing or isolation.
Why teams look beyond Gemini API code execution
A free, bounded Python scratchpad for Gemini calls; reach for a real sandbox when you need more than 30 seconds, state or network.
- 30-second maximum runtime and Python only, so it is not suitable for builds, long scripts or other languages
- No custom packages, no documented filesystem persistence and no documented network access
- Isolation technology is not documented, so it cannot be assessed for sensitive workloads
- The docs warn that enabling code execution can cause regressions in other outputs, such as creative writing
Gemini API code execution alternatives, by kind
Cloud provider code execution
Managed code-execution tools from AWS, Azure, Google Cloud and OpenAI.
Azure Container Apps dynamic sessions
Azure service that hands out Hyper-V-isolated sessions from prewarmed pools, either as a built-in code interpreter or running your own container image.
- Hyper-V VM
How it differs: Azure-native apps running LLM-generated Python or Node code with egress off by default. A solid, locked-down code interpreter for Azure shops; not designed for long-lived coding agents.
Claude code execution tool
Server-side tool in the Claude API that runs Bash commands, Python and file edits inside an Anthropic-hosted container with no internet access.
- Hosted Linux container
How it differs: Data analysis, file generation and multi-step scripting inside a Claude API conversation without running your own sandbox. The simplest way to give Claude a scratch computer for analysis and file work, provided you can live without network access and custom environments.

Google Agent Platform Code Execution
Google-managed sandbox API (formerly part of Vertex AI Agent Engine) that lets agents deployed anywhere run Python in stateful, network-isolated environments.
- gVisor
How it differs: Google Cloud agents that need stateful, no-network Python execution. A tightly locked-down Python tool for Google Cloud users; too constrained for coding agents.
Mistral code interpreter
Built-in tool of the Mistral Agents API that runs Python the agent writes in an isolated container.
- Isolated container
How it differs: Letting a Mistral agent run short Python for maths, data analysis and plots without an external sandbox. Convenient inside the Mistral Agents API, but thinly documented; look elsewhere if you need to know what the container can do.

OpenAI Code Interpreter & Hosted Shell
Hosted containers in the OpenAI Responses API that the model uses to run Python (Code Interpreter) or shell commands (Hosted Shell).
- VM (unspecified)
How it differs: Apps already on the OpenAI Responses API that want model-driven code execution with no extra vendor. Convenient for OpenAI-native apps; choose a dedicated sandbox for multi-model agents or persistent workspaces.
