Bifrost vs LiteLLM: Two Self-Hosted AI Gateways, a Go SDK vs a Python SDK
Bifrost
Open-source AI gateway that puts 20+ LLM providers and MCP tools behind one OpenAI-compatible API
LiteLLM
Open-source AI gateway and Python SDK that puts 100+ LLM providers behind one OpenAI-format API
Verdicts par tâche
Bifrost ships as a Go SDK (github.com/maximhq/bifrost/core) as well as an HTTP gateway; LiteLLM's embeddable SDK is Python.
Bifrost's speed claims, including 50x faster than LiteLLM, are its own and unmeasured by us.
LiteLLM's Python SDK is a drop-in replacement for the OpenAI client across 100+ LLMs.
Pin versions: compromised PyPI releases 1.82.7 and 1.82.8 were live on Mar 24, 2026. If you run the Proxy, move to a release patched for the Sep 30, 2026 advisory GHSA-7hp6-4w63-5g45 (for example 1.100.4 or later on that line).
LiteLLM's docs say 100+ LLMs and its site 140+ providers; Bifrost's docs say 20+ and its README 23+.
Each vendor counts differently; both cover OpenAI, Anthropic, Bedrock, Vertex, Azure and Ollama.
Bifrost documents MCP tool execution, agent mode with auto-approval, code mode, five authentication types, and running itself as an MCP server; LiteLLM documents a central MCP endpoint with per-key access control.
CVE-2026-90898 (CVSS 9.8) sat on Bifrost's MCP client registration path, with management authentication off by default; upgrade to 2.1.0 and enable auth.
LiteLLM lists LLM guardrails in its free open-source plan; Bifrost reserves guardrails for Enterprise.
LiteLLM's CVE-2026-59821, a post-auth remote code execution through custom code guardrails, was fixed in v1.82.0.
LiteLLM emails a 30-day self-hosted Enterprise trial key with no credit card and no mandatory sales call; Bifrost Enterprise goes through a demo request with a 14-day trial.
Neither publishes an Enterprise price.

Same job; the embeddable SDK is Go for Bifrost and Python for LiteLLM
Both permissive open source
LiteLLM covers more providers by both vendors' own counts
Comparable in both free editions
LiteLLM includes guardrails at $0
Bifrost documents a broader MCP surface
Neither publishes a price; LiteLLM's trial is longer and needs no sales contact
Both are vendor figures from different setups; we have measured neither
Both ship insecure defaults and critical flaws; LiteLLM's MCP flaw is confirmed exploited in the wild and its newest advisory scores higher (9.9 vs 9.8)
LiteLLM's community is several times larger
Both powered
