LiteLLM is the safer default; Bifrost wins only when microsecond overhead and raw RPS rule

Asked:

“which tech is truly better? litellm or bifrost?”

The evidence is 15 extracted comparison rows across nine independent hosts (one row per URL), scoring the two gateways on provider breadth, ecosystem, operations, governance, and performance. “Bifrost Enterprise” rows are merged into Bifrost; one weakly relevant agent-session-persistence row is shown in the table but kept out of the scorecard. All Bifrost performance figures come from Bifrost/Maxim-controlled sources.

Best default

LiteLLM

100+ providers, ~58k stars, Helm/Kubernetes patterns, OpenTelemetry v2 tracing, built-in local content filtering. Pick it unless benchmarks on your own workload prove its overhead is a bottleneck.

Performance specialist

Bifrost

Go gateway with claimed ~11µs overhead at 5,000 RPS and ~3,000–5,000 RPS per OSS instance — vendor-published numbers. Fits latency-critical, high-RPS stacks where 20+ providers suffice and Enterprise gating of clustering, RBAC, and audit is acceptable.

Decision tree

Is gateway overhead or single-instance RPS a proven bottleneck on your workload?

No, or not yet measured → LiteLLM — breadth and maturity win by default.

Yes → Do 20+ providers cover every model you need, and can you accept adaptive balancing, clustering, RBAC, and audit sitting behind Bifrost Enterprise?

Yes → Bifrost — but reproduce the ~11µs / 5,000 RPS benchmark yourself with identical streaming, concurrency, auth, and logging settings.

No → LiteLLM, and scale it horizontally on Kubernetes.

What the scorecard cannot say alone

Method: 15 comparison evidence rows extracted from nine independent hosts, one row per URL; snapshot of a 2026-dated document set. Each row carries a product, buying criterion, finding, and quantitative metric where stated. Scorecard levels are editorial judgments over the cited findings; Bifrost throughput and overhead figures and the freshcrate “50x” figure are vendor claims, not independent measurements. Long findings truncated for space; full sources linked per row.
