The top alternatives to The Token Company in the LLM Gateways space, compared on features, pricing, and what they're best at.
Updated March 27, 2026
The Token Company builds a drop-in compression API that preprocesses LLM inputs using fast ML models to remove redundant tokens from prompts, chat histories, and RAG documents. Part of YC W2026, it was founded by Otso Veistera — reportedly the youngest solo founder in YC history at 18 years old. YC partners reached out directly rather than through the standard application process.
Respan is a unified AI gateway that provides a single API endpoint to access 250+ LLMs from every major provider. It offers intelligent model routing, fallback strategies, cost optimization, load balancing, and real-time observability—enabling teams to build resilient AI applications without vendor lock-in. Respan simplifies multi-model orchestration with built-in caching, rate limiting, and usage analytics across all providers.
OpenRouter is a unified LLM gateway providing OpenAI-compatible API access to 300+ models across 60+ providers (OpenAI, Anthropic, Google, Meta, Mistral, and more). Pay-as-you-go with passthrough rates plus a 5.5% platform fee on credit purchases; free tier with 25+ models capped at 50 requests/day.
Cloudflare AI Gateway is a proxy for AI API traffic that provides caching, rate limiting, analytics, and logging for LLM requests. Running on Cloudflare's global edge network, it reduces latency and costs by caching repeated requests. Free to use on all Cloudflare plans.
Vercel AI Gateway provides a unified API for accessing multiple LLM providers with built-in caching, rate limiting, and fallback routing. Integrated into the Vercel platform, it offers edge-optimized inference, usage analytics, and seamless integration with the Vercel AI SDK for production AI applications.
Portkey is an AI gateway that provides a unified API for 200+ LLMs with built-in reliability features including automatic retries, fallbacks, load balancing, and caching. The platform includes observability with detailed request logs, cost tracking, and performance analytics. Portkey also offers guardrails, access controls, and virtual keys for managing LLM usage across teams.
LiteLLM is an open-source LLM proxy that translates OpenAI-format API calls to 100+ LLM providers. It provides a standardized interface for calling models from Anthropic, Google, Azure, AWS Bedrock, and dozens more. LiteLLM is popular as a self-hosted gateway with features like spend tracking, rate limiting, and team management.
Helicone is an open-source LLM observability and proxy platform. By adding a single line of code, developers get request logging, cost tracking, caching, rate limiting, and analytics for their LLM applications. Helicone supports all major LLM providers and can function as both a gateway proxy and a logging-only integration.
Unify provides intelligent LLM routing that automatically selects the optimal model and provider for each request based on quality, cost, and latency constraints. It benchmarks 100+ endpoints across providers and dynamically routes traffic to maximize performance while minimizing costs.
Martian is an intelligent model router that automatically selects the best LLM for each request based on the prompt content, required capabilities, and cost constraints. Using proprietary routing models, Martian optimizes for quality and cost simultaneously, helping teams reduce LLM spend while maintaining or improving output quality.
Kong AI Gateway extends the popular Kong API gateway with AI-specific capabilities including multi-LLM routing, prompt engineering, semantic caching, rate limiting, and cost management.
Unified LLM gateway and router with intelligent routing, automatic failover, cost optimization, and PII redaction. Access 400+ models through a single API.
