Gateway alternative
Cheap OpenAI API alternative with prepaid spend controls
developers searching for lower waste through limits, logs, and prepaid balance. NexRelay is built for a narrower job: make compatible API testing predictable with trial credits, prepaid wallet protection, and request-level visibility.
When this alternative makes sense
A prepaid gateway is useful when the user wants a working compatible endpoint first, then wants to raise limits only after logs confirm model, token, and cost behavior.
What NexRelay focuses on
The product is optimized for controlled testing and simple developer workflows.
- OpenAI-compatible, Claude-compatible, and Gemini-style routes
- Trial credits before payment
- Wallet balance checks before routing
- Per-key budgets, model policy, and output caps
- Request-level logs for billing review
What to compare before switching
Check endpoint compatibility, supported models, latency, refund policy, support channel, and actual cost for your workload before moving production traffic.
