What is the best OpenRouter alternative in 2026?
There is no single best choice. TrustedRouter fits teams that want hosted multi-provider access with a hardware-attested prompt path. LiteLLM fits teams that want to self-host. Portkey fits governance-heavy gateway deployments. Vercel AI Gateway fits Vercel and AI SDK applications. Bedrock and Vertex AI fit cloud-native procurement and IAM.
What is the easiest OpenRouter alternative to migrate to?
An OpenAI-compatible hosted gateway is usually the easiest migration because the SDK can stay in place. With TrustedRouter, change the base URL to https://api.trustedrouter.com/v1, replace the API key, and test the model IDs and provider controls used by your application.
Which OpenRouter alternative can I self-host?
LiteLLM is designed for teams that want to operate their own OpenAI-compatible proxy. Portkey and Helicone also publish self-hosting options. TrustedRouter publishes its gateway and control-plane source for teams that want the same routing and attestation architecture under their own control.
Which OpenRouter alternative is best for privacy?
Compare the entire request path, not only the gateway policy. TrustedRouter's attested gateway never stores prompt or output content. Every downstream route separately identifies zero-data-retention status and independently verified end-to-end confidential compute so sensitive workloads can fail closed on the required privacy tier.
Can I keep using the OpenAI SDK?
Yes. TrustedRouter, LiteLLM, Portkey, Vercel AI Gateway, Cloudflare AI Gateway, Helicone, and Requesty all offer OpenAI-compatible paths. Compatibility varies for advanced fields, Responses API features, tools, images, streaming events, and provider-specific controls, so test the exact surface your application uses.
