1. Planning 2. Tools 3. Execution environment
Execution is often overlooked. Agents need somewhere to run code, install deps, write files, and continue workflows safely.
We ran into this while building agents, so we built Sandflare — sandboxes with memory that launch in milliseconds.
Agents can spin up environments, run code, and continue later without losing context.
