The short version

Each has a real cost: LiteLLM enterprise pricing based on annual request capacity and deployment architecture, sized via direct sales; Zeplo zeplo sits directly in the execution path of your background work, so an outage at a very small vendor means your jobs do not run at all, and there is no published SLA below Enterprise.

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

LiteLLM

Enterprise pricing based on annual request capacity and deployment architecture, sized via direct sales
Not per-token based pricing for Enterprise tier

Zeplo

Zeplo sits directly in the execution path of your background work, so an outage at a very small vendor means your jobs do not run at all, and there is no published SLA below Enterprise.
The free Developer tier includes only 500 requests a month and one team member, so it is a demonstration allowance rather than a usable free plan for anything real.
Overage on the Developer tier is 20 US dollars per 100,000 requests, two hundred times the marginal rate on the Company tier, so exceeding the free allowance without upgrading is expensive.
Team members cost 15 US dollars each beyond the plan allowance, which is an odd charge on an infrastructure product billed by request volume.
Log retention is 30 days on both published tiers, so anything requiring longer audit trails on job execution has to be logged separately.
