Best Alternatives to TrustedRouter in 2025

OpenRouter is the most direct competitor, offering a massive model catalog (including community and niche models) with a simple pay-per-token pricing model. It excels in developer experience, providing unified API access, automatic fallbacks, and rich analytics. However, it lacks TrustedRouter's confidential computing and zero-data-retention guarantees, making it better for teams prioritizing model variety and cost over hard privacy proofs.

LiteLLM is an open-source Python library and proxy that standardizes calls to 100+ LLM providers (OpenAI, Anthropic, Azure, Bedrock, etc.) behind an OpenAI-compatible interface. It is ideal for teams that want full control over their infrastructure, on-premise deployment, and custom routing logic. Unlike TrustedRouter, LiteLLM does not provide attestation or end-to-end encryption out of the box, but it offers transparency, self-hosting, and no per-token fees.

Portkey is a robust AI gateway with features like caching, rate limiting, retries, load balancing, and observability across multiple providers. It offers a hosted service or self-hosted option, and its control plane is more mature for production traffic management. While it provides some security features (e.g., PII redaction), it does not match TrustedRouter's confidential computing or zero-knowledge proofs, making it a better fit for teams needing advanced operational controls rather than cryptographic privacy.

Kong, a leading API gateway vendor, has added AI-specific capabilities (model routing, key management, and prompt templating) to its enterprise gateway. It is best for organizations already invested in Kong's ecosystem who want to enforce governance, security policies, and traffic management across AI endpoints. It lacks TrustedRouter's attestation and zero-retention routes, but offers deep integration with existing enterprise infrastructure and compliance frameworks.

Helicone is an open-source observability and gateway platform that proxies requests to OpenAI and other providers, offering logging, caching, and cost tracking. It is lightweight and developer-friendly, with a focus on debugging and optimization rather than privacy guarantees. For teams that need to monitor usage and reduce costs without the complexity of a full security layer, Helicone is a simpler alternative, though it does not provide confidential computing or BYOK encryption.

Cloudflare's AI Gateway provides a unified endpoint to multiple AI providers, with built-in caching, rate limiting, and analytics, all on Cloudflare's global edge network. It is a good choice for developers already using Cloudflare Workers or Pages, offering low latency and simple integration. However, it does not offer attestation or zero-data-retention options, and its model catalog is smaller than TrustedRouter's. It suits teams that prioritize edge performance and existing Cloudflare workflows.

For enterprises heavily invested in Microsoft's cloud, Azure AI Foundry (formerly Azure AI Studio) provides a unified gateway to Azure OpenAI, Meta, Mistral, and other models, with enterprise-grade security, compliance, and private networking. It offers strong data governance and virtual network integration, but it is tied to Azure's ecosystem and does not provide the same level of cross-provider neutrality or cryptographic attestation as TrustedRouter. It is best for organizations that require deep Azure integration and regulatory compliance.
