Grass
Grass provides a dedicated, pre-configured VM for coding agents—no local setup. Works with Claude Code and OpenCode and supports your own API key.
What is Grass?
Grass provides a dedicated, pre-configured virtual machine (VM) intended for use with coding agents. Its stated purpose is to keep an agent-ready compute environment available without requiring setup or configuration on the user’s side.
The site positions Grass as “VM-first compute for coding agents,” and highlights compatibility with Claude Code and OpenCode, with additional agents expected.
Key Features
- Pre-configured Daytona VM: Gives your coding agent a ready-to-use VM environment without you configuring it first.
- Dedicated VM for agent work: Keeps agent compute separate from your local workflow (“no burning your laptop,” as described).
- “Bring Your Own Key” support: Your API key stays yours; the site says it never takes or touches your key.
- Agent support for Claude Code and OpenCode: Works with these coding agents today, with more agents planned.
- Starter access with time included: The page mentions a free start of “10 hours on us” and indicates there’s no credit card.
How to Use Grass
- Start your account to access the provided pre-configured Daytona VM (the site describes a free start of 10 hours with no credit card).
- Use the VM with a supported coding agent, such as Claude Code or OpenCode.
- Configure the agent to use your own API key (“Bring Your Own Key”), keeping control over the key since the site says it never touches it.
Use Cases
- Running a coding agent without local setup: When you want agent-driven coding tasks to run in a separate VM rather than on your own machine.
- Using Claude Code for development tasks: If your workflow depends on Claude Code, Grass provides the dedicated compute environment it can run against.
- Using OpenCode for agent-assisted coding: When you prefer OpenCode and need an always-ready VM environment.
- Team experimentation with agent tooling: For teams that want a consistent, pre-configured VM target for agent trials without each person repeating configuration.
- Preparing for additional agents: If your team is planning to test more coding-agent tools beyond Claude Code and OpenCode, the site indicates further support is coming.
FAQ
Does Grass require me to configure the VM? The page emphasizes a pre-configured Daytona VM and says you can use it with “no setup, no config.”
Can I use my own API key? Yes. The site states “Bring Your Own Key” and that your API key stays yours, with no access or handling by Grass.
Which coding agents does Grass work with? The page explicitly mentions compatibility with Claude Code and OpenCode, and notes that more agents are expected.
Is there a free way to start? The meta description and on-page text state that you can start free with “10 hours on us” and that no credit card is required.
What is the Daytona VM mentioned on the site? Grass includes a “pre-configured Daytona VM” for use as the compute environment for coding agents.
Alternatives
- Managed VM or cloud development environments: Instead of a dedicated VM tailored for coding agents, you can use a general-purpose cloud VM and configure it for your agent workflow.
- Local agent execution with environment setup: Some workflows run agents on your machine; this trades the “pre-configured, always ready” approach for local configuration and resource usage.
- Agent platforms that abstract away compute: Some tools bundle infrastructure under an agent interface, reducing the need to manage or provision a VM, though they may not align with a VM-first workflow.
- Containerized dev environments: For teams that prefer containers over VMs, setting up container-based environments can provide isolated execution, with configuration controlled by the team rather than pre-provided compute.
