Use Case Recommendations
Best for: LLM Gateway
LLM Gateway is an open-source, OpenAI-compatible routing layer that puts one API in front of more than 200 models across 40-plus providers, including OpenAI, Anthropic and Google. The problem it solves is operational rather than intellectual: teams that use several providers end up juggling separate keys, separate dashboards, separate billing and separate SDK quirks, and switching provider for a given model means a code change. Pointing an existing OpenAI-compatible client at the gateway collapses that into one endpoint with real-time cost tracking across all of it. Around the core routing sit the features that make a gateway worth running in production — automatic provider selection and custom routing rules, budgets and spend controls, prompt caching, guardrails, reliability failover, and activity logs with exportable data. The commercial model is unusual and worth reading carefully: the free tier is free forever with all 200+ models available and bring-your-own-keys included, and the platform fee is 5% on credit usage rather than a monthly subscription, so cost scales with spend rather than seats. Metadata retention is free while full payload storage is billed at $0.01 per million tokens. Supporting surfaces include an MCP server, an AI SDK provider, a token cost calculator, model comparison and rankings pages, and the vendor states it is SOC 2 Type II certified.
Ideal use cases:
- •Teams or individuals who need one openai-compatible endpoint for 200+ models across 40+ providers
- •Teams or individuals who need real-time cost tracking and spend controls across every provider
- •Teams or individuals who need automatic provider routing plus custom routing rules
- •Teams or individuals who need prompt caching, guardrails and reliability failover
- •Anyone focused on llm-gateway workflows
- •Anyone focused on api workflows
Best for: Runflow
Runflow is managed AI image infrastructure sold as an engagement rather than a self-serve SaaS: the company designs the image workflow, hosts every model it runs on, operates it in production and scores every output before it reaches your users. The problem it names is specific and familiar — teams ship an AI image feature, the demo works, and then it stalls in production because nothing observes it. Runflow's answer has three parts. Observability means every run through your stack is visible rather than fire-and-forget. Quality gating is handled by Sentinel, which scores each generated image against the workflow's checks; with strict gates on, a run halts the moment one image fails, so credits are not burned generating on top of a bad result. And cost control comes from routing across 700+ open-source and frontier models rather than defaulting to the most expensive frontier call for every render. The delivery model is a white-labelled editing studio embedded inside your product in your own colours, with you billing your customers — the vendor names BetterPic and Fabel as skinned deployments. Eighteen pre-built solutions are available on day one, including product-to-lifestyle shoots, background removal, ad creative generation, smart resize and scene placement, and these carry no build fee because they already run in production.
Ideal use cases:
- •Teams or individuals who need sentinel scores every generated image before it reaches users
- •Teams or individuals who need strict quality gates halt a run rather than burning credits on a bad result
- •Teams or individuals who need white-labelled editing studio embedded in your product
- •Teams or individuals who need routing across 700+ open-source and frontier models
- •Anyone focused on ai-image workflows
- •Anyone focused on managed-infrastructure workflows
