Not Every Workload Belongs on a Free Server: Red Flags and Exit Criteria

A recent deployment went awry when an engineer transferred a code-review agent to a free server. Despite every test yielding correct model responses, the server hit its quota at 2:47 PM on the third day. Consequently, 14 pull request verdicts were lost, leaving no state, logs, or opportunities for retry. This incident highlights a potential blind spot in teams that focus heavily on testing models but often neglect to evaluate the underlying runtime environment.

Free server options, such as MonkeyCode's free model access and free server feature, come with several red flags. These constraints include quota exhaustion, state loss, and contention. Quota exhaustion occurs when token budgets reset on a schedule, causing heavy days to deplete the entire cycle without any warning. State loss happens when free servers restart without notice, leading to the disappearance of in-memory sessions and long-running agents losing their context.

Contention manifests as shared resources causing cold starts, rate limits during peak hours, and increased latency due to random variables.

To avoid these pitfalls, a concrete example has been provided: MonkeyCode's free model access and free server option. While the free model access provides 10 million tokens per cycle, the free server runs the agent without a paid VM, presenting both opportunities and constraints. Free infrastructure should be treated as a trial environment, not a production contract, as it has its limitations.
