I burned through half of my E2B sandbox budget in just two weeks by spinning up containers for AI agents that often ran for only eight seconds.
I had been integrating AI coding agents into a few automation scripts on TecMint’s backend. These agents would generate a draft, run a command, check the output, and repeat the process until the task was complete.
Since I didn’t want an AI agent running random shell commands directly on my production server, every task needed its own isolated environment. Like many people, I started with Docker and later switched to a hosted sandbox service when Docker’s startup time became a bottleneck.
