Cheaper OpenAI Agents API alternative: sandbox service undercutting E2B by 46%
airesearch12 · x · 2026-09-11
The author shares a cheaper, more controllable alternative to OpenAI's Agents API: pair the sandbox-as-a-service.com sandbox with the opencode agent CLI and cheap models from OpenRouter such as DeepSeek V4.1 Flash.
Key features of the sandbox service:
- No SDK needed: plain HTTP or an MCP server; three commands give your agent a dedicated VM it can break in about a minute
- Priced at $0.09/hour, 46% under E2B, with $5 free credit and no card required
- Dedicated kernel, never-shared VM, 24-hour sessions, and Preview URLs to share what the agent built
- Full cURL/Python/JavaScript examples included: create sandbox → exec command → destroy, suited for running untrusted model-generated code
