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: Pitch31
Pitch31 turns an API you already ship into a conversational agent your users can talk to, without you writing the agent layer. You upload an OpenAPI specification or a Postman collection, and Pitch31 reads the endpoints, parameters and auth requirements and builds an agent from them; the agent can then be left public or embedded directly inside your own product. The point of the product is the learning curve rather than the chat interface: instead of teaching users where a feature lives in your UI, they type what they want in plain language and the agent maps it onto the right sequence of calls. It supports typed input in over 130 languages. Agents chain multiple API calls together for a single instruction, hold authentication on the client rather than proxying credentials through Pitch31, and repair invalid payloads on the fly rather than surfacing a validation error back to the user. A worked example on the site walks a single prompt through creating a user in a CRM, sending a welcome email through Mailgun, creating a Stripe customer and granting dashboard permissions, showing each step's execution state. Users and roles are first-class, so an embedded agent can respect the same permission model the underlying API already enforces. Plans are metered in credits and API agents rather than seats.
Ideal use cases:
- •Teams or individuals who need builds an agent directly from an uploaded openapi spec or postman collection
- •Teams or individuals who need chains multiple api calls from one plain-language instruction
- •Teams or individuals who need authentication handled client-side rather than proxied through the vendor
- •Teams or individuals who need repairs invalid payloads in flight instead of erroring back to the user
- •Anyone focused on api workflows
- •Anyone focused on openapi workflows
