Requesty Alternatives in 2026: 10 Gateways Compared

Updated 2026-08-16 · ~5 min read

If you are leaving Requesty over billing — wanting a hard ceiling rather than a bill settled afterwards — SuperbAPI is the closest fit: prepaid credit, no subscription, and a budget cap per key. If you are leaving over what Requesty covers, OpenRouter is the nearest substitute, being one key and one balance across many vendors' models. Both, and eight more, are ranked below — with a straight account of where Requesty is still the better answer.

Why do people look for Requesty alternatives?

The usual aggregator-to-aggregator reasons: wanting prepaid credit with a hard ceiling rather than metered usage settled later, wanting a per-key budget cap, or wanting a specific model that is not in the catalogue.

The 10 alternatives at a glance

This is a comparison published by SuperbAPI, and SuperbAPI is listed first. Billing models are shown rather than prices: rates change often enough that any figure printed here would be wrong before it was useful. Check current pricing with each provider.

The 10 alternatives in detail

1. SuperbAPI

An independent, prepaid, OpenAI-compatible aggregator: one balance, one base URL, and text, code, image and video models behind a single key.

You top up once and every call draws down that balance at the model's own rate — no subscription, no monthly minimum, and no invoice arriving after the fact. Keys can be scoped to specific models and given a budget cap, so a test key cannot spend production's money, and credit is valid for 12 months. Requests fail over to another upstream serving the same model, and a call that ultimately fails bills nothing.

2. OpenRouter

The gateway that popularised one API key for every model, and still the broadest catalogue in the category.

Same category as Requesty — one key and one balance across many vendors' models — so the switch is a like-for-like one. The difference that matters is billing: credits, plus bring-your-own-key, against Requesty's usage-based.

3. AI/ML API

A multi-model aggregator offering a large catalogue behind one key, on plans combining a subscription with usage.

4. Together AI

An inference platform that hosts open-weight models itself, with fine-tuning and dedicated endpoints alongside the shared API.

A different shape of product from Requesty: a platform that hosts and serves open-weight models itself. Worth the move only if what you actually need is open-weight inference and fine-tuning at serious volume — otherwise it solves a problem you do not have.

5. Fireworks AI

An inference platform focused on serving open-weight models fast, with fine-tuning and enterprise deployment options.

Also worth knowing

These are further from what Requesty does, but each is the right answer to a specific question:

• 6. Groq — The fastest tokens per second on a curated open-model set. Postpaid, with a free tier.
• 7. Replicate — Image, video and audio models, plus custom model deploys. Per-second compute.
• 8. Portkey — Routing, caching, guardrails and observability over your own keys. SaaS or self-hosted; you bring provider keys.
• 9. LiteLLM — A self-hosted proxy normalising many providers to one format. Open source, self-hosted; paid enterprise tier.
• 10. Helicone — Logging, tracing and cost attribution for LLM calls. Open source or cloud; you bring provider keys.

Where Requesty still wins

Routing sophistication for cost. If your priority is automatically steering each request to the cheapest acceptable model, a gateway built around that idea is aimed squarely at your problem.

How to migrate off Requesty

OpenAI-compatible on both sides, so base URL, key and model IDs. Move one route, compare cost and output on real traffic for a few days, then switch the rest.

Requesty alternatives: common questions

What is the best Requesty alternative?

OpenRouter for the largest catalogue, SuperbAPI for prepaid billing with per-key budget caps. All three are OpenAI-compatible, so switching is a base URL and key change.

Which AI gateway has the best cost control?

Cost control has two halves: routing to cheaper models, and preventing overspend. Routing-focused gateways do the first; prepaid credit with per-key caps does the second by making the balance a hard ceiling.

Is prepaid or usage-based better?

Prepaid caps your maximum loss at what you already paid. Usage-based is settled afterwards, so a runaway loop is discovered on the invoice.

Where SuperbAPI fits

SuperbAPI is an independent, prepaid, OpenAI-compatible aggregator: one wallet, one base URL, and text, code, image and video models behind a single key. Keys can be scoped to specific models and capped with a budget, so the balance is a hard ceiling rather than a starting point.
