Martian Gateway review
A broad LLM gateway for developers who want compatible APIs and model choice.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
Martian Gateway is an API-centered service for developers who need access to more than 200 language models from multiple providers. It supports OpenAI-compatible Chat Completions and Anthropic-compatible Messages APIs, so teams can work with established SDKs and frameworks while choosing models through a common gateway. The product also includes a web interface for model discovery and monitoring, with provider and pricing information in its catalog.
Compatibility is a central strength. Documented integrations include the OpenAI SDK, Anthropic SDK, Vercel AI SDK, LiteLLM, HTTP clients, and developer tools such as Cursor, Claude Code, Claude Desktop, Cline, OpenCode, and Codex. Streaming responses, tool and function calling, API-key authentication with bearer tokens, and usage, model-performance, and request-history monitoring cover several practical requirements for applications that call language models in production. Developers can also use model-level token pricing information when comparing available options.
The pricing structure is oriented around model-level token rates rather than fixed subscription tiers, so cost assessment depends on the models selected and their published rates. That approach suits teams comparing providers or changing models through compatible APIs, but the breadth of the catalog can make model selection more involved. Martian Gateway is a good fit for developers who value broad model access, SDK compatibility, and request visibility. Teams looking for a complete application-building environment or a narrowly focused model experience should consider a more specialized product.
Martian Gateway pros and cons

- OpenAI- and Anthropic-compatible APIs support existing SDKs
- Streaming, tool calling, and real-time usage monitoring
- Where it doesn't
- Pricing follows model-level token rates rather than fixed subscription plans
- The broad catalog can add model-selection overhead
- Its scope centers on API access rather than a complete application platform
