| Composes with | 40 Nano-VM hours a month is a free headless Linux box with a filesystem and a port, which is what a build, a scrape or a test run needs; it is the cheapest server-shaped free tier per credit, and it composes with any static host for the output. |

| Reliability | no reliability event recorded |

| Notes | The credits are worth USD 6 a month at the vendor's own rate, which is small in dollars and large in hours because a Nano VM is one vCPU. The pricing page and the docs disagree: the 40-hour bullet was removed from the pricing page in September 2026 while the docs still state 400 credits, so the allowance may be mid-change. compute/codesandbox-sdk already records the SDK from Together AI's docs, not this free tier; merge into one CodeSandbox record. Browser Sandboxes do not consume credits, so the 20-Sandbox allowance is a separate and unmetered free lane. |
