LLM Gateway
One API for routing and monitoring LLM traffic across 40+ providers and 200+ models, with BYOK included in the $0 Free plan.
About LLM Gateway
LLM Gateway puts 40+ providers and 200+ models, including OpenAI, Anthropic, and Google, behind one API. Developers can keep familiar OpenAI SDK code and change the base URL, which makes provider comparisons and later switches less disruptive. The service also handles usage logs, cost analytics, managed keys, and playground testing. BYOK comes with the $0 Free plan. Requests funded with credits bought through the platform carry a 5% platform fee. Free accounts receive three rate-limited free models and 30-day data retention. Enterprise uses custom pricing and begins with a 30-day trial. It adds volume discounts, custom routing rules, unlimited retention, audit logs, guardrails, SSO/SAML, and contractual SLAs. This setup fits teams that want one gateway and a clearer view of spend. The practical costs are another dependency in the request path, compatibility testing when provider behavior differs, and an Enterprise agreement for advanced governance.
Best for
Best use cases
An application needs to change providers or models without rebuilding its client integration for every vendor.
During monthly cost review, operators consolidate request, token, and spending data from several projects in one dashboard to reconcile budgets and compare providers.
A governed deployment needs routing policies, longer retention, identity management, and auditable administrative activity.
Compare before choosing
Compared with direct provider integrations, one gateway reduces integration duplication but adds another service to the request path.
BYOK can avoid the 5% platform fee on purchased credits, though teams still manage their own provider accounts and keys.
The Free plan covers core routing and 30-day retention; enterprise governance and custom limits require a sales agreement.
Features
Multi-provider application routing
Connect an application through one API, then switch models or providers without rewriting the existing OpenAI SDK integration.
LLM cost and usage analysis
Track requests, token volumes, total spend, and cost per 1K tokens across providers to support budgeting and provider comparisons.
Enterprise AI governance
Use audit trails, administration controls, routing policies, guardrails, SSO/SAML, and retention settings for governed team deployments.
Pros
- One API and familiar OpenAI SDK patterns reduce integration work when adding or switching providers.
- The $0 Free plan includes BYOK, which avoids the 5% fee charged when usage is funded with platform credits.
- Request, token, and cost analytics give teams a shared view of spending and provider performance.
Cons
- Using a gateway adds an external service to the request path, creating another operational dependency.
- Provider and model behavior can differ, so switching routes may still require application-level compatibility testing.
- Unlimited retention, SSO/SAML, guardrails, custom routing, and contractual SLAs require the custom-priced Enterprise plan.
