Runtime config

Configure environment variables, secrets, and VM resources for Capy task execution — set API keys, database URLs, and runtime settings per project.

Environment variables

Set project secrets that are injected into the VM during task execution (API keys, DB URLs, etc.).

Configure them from:

• Project configuration page
• Settings → Project → Devbox

You can add key-value pairs directly or paste a full .env file.

Environment variables are available to the agent during task execution. Only provide secrets you’re comfortable sharing with the agent.

VM size

Each task runs in an isolated Ubuntu VM. Choose the size that matches your workload:

Size	CPU	RAM	Disk	Cost/hour
Small	2 cores	4 GB	20 GB	$0.15
Medium	4 cores	8 GB	30 GB	$0.30
Large	8 cores	16 GB	40 GB	$0.60
Ultra	16 cores	32 GB	50 GB	$1.20
Hyper	16 cores	64 GB	50 GB	$1.50

Small is the default and works for most tasks. Use larger sizes for heavy builds, large test suites, or resource-intensive compilation.

To change VM size:

1. Open project Configuration, or Settings → Project → Devbox
2. Select the VM size
3. Save

Changes apply to the next run.
