Bifrost vs Helicone (2026)
Updated March 10, 2026
Overview
Bifrost is an open-source LLM gateway from Maxim AI, written in Go, that puts 1,000+ models from 20+ providers behind one OpenAI-compatible API.
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.
