Tracelane vs LiteLLM

LiteLLM is a widely-adopted open-source Python proxy, and a reasonable default for a lot of teams. This page is about one specific axis: what the request path is written in, and what you can verify about the artifact you deploy. Tracelane is a Rust gateway. Every release since v0.2.3 ships Cosign keyless-signed binaries and a signed CycloneDX SBOM; the release workflows are also configured for Trusted Publishing OIDC and build provenance, and the repository runs a vuln-scanning stack of OSV-Scanner + Grype + Syft. Verify any artifact you download with cosign rather than taking this page’s word for it.

How we compare

Claim	Tracelane	LiteLLM
Language on request path	Rust (Apache 2.0)	Python (MIT per its repository)
Supply-chain posture	Cosign keyless-signed binaries and SBOM on every release since v0.2.3; OSV-Scanner + Grype + Syft	Not documented
Token model	Trusted Publishing OIDC (no long-lived registry tokens)	Not documented
Vuln scanning	OSV-Scanner + Grype + Syft	Not documented
Gateway overhead	Low — no interpreter on the hot path: 2 ms p50 / 4 ms p95 / 5 ms p99 added, measured with LiteLLM’s own AIGatewayBench harness (4 vCPU, two runs, capture on) — see benchmarks	Python interpreter on the hot path
BYOK key custody	Envelope encryption, AAD bound to (tenant_id, provider_id)	Keys commonly supplied via proxy config / environment
Audit ledger	Tamper-evident hash chain + Merkle + Ed25519 per-tenant signing (live); best-effort Rekor v2 inclusion proof on anchored batches	Not documented
Inline guardrails	Heuristic rails at the gateway (R1–R8), verdicts written to the ledger	Guardrail integrations documented; ledgered verdicts not documented
Self-host complexity	Single-node Docker Compose (ClickHouse-backed)	Docker Compose documented (BerriAI/litellm)
Migration tool	`tlane import-litellm` reads litellm_config.yaml	—

Migration

# 1. Translate your LiteLLM config
tlane import-litellm --config ./litellm_config.yaml --output ./tracelane.yaml

# 2. Verify the gateway binary signature (Cosign keyless)
# Use a current cosign release to verify.
cosign verify-blob --certificate-identity-regexp \
  'https://github.com/tracelane/tracelane/.github/workflows/release.yml@.*' \
  --certificate-oidc-issuer 'https://token.actions.githubusercontent.com' \
  --bundle ./tracelane.bundle ./tracelane

# 3. Point your agents at the new gateway endpoint
export OPENAI_BASE_URL=https://gateway.tracelane.dev/v1

FAQ

Does Tracelane have feature parity with LiteLLM?

For the request-path features (multi-provider routing, failover, retry, usage/token tracking, BYOK), yes. Tracelane adds inline predictive guardrails, a tamper-evident audit ledger, and OTel GenAI semconv as its canonical wire format; we found none of the three documented for LiteLLM as of 2026-08-26.

Is tlane import-litellm a complete migration?

It translates the model_list, router_settings and callback entries of litellm_config.yaml into Tracelane gateway config; use --dry-run to review the output before writing it. Custom Python hooks in your LiteLLM proxy do not auto-port — you’ll rewrite those as Tracelane gateway middleware or as separate services. Review the generated config before use.

What is Tracelane's vuln-scanning stack?

OSV-Scanner (Google) for upstream advisories, Grype (Anchore) for container scanning, and Syft (Anchore) for CycloneDX SBOM generation. Tagged releases carry a Cosign-signed CycloneDX SBOM (sbom.cyclonedx.json plus its .cosign.bundle), as the v0.2.3 and v0.3.0 releases do. See Security.

Verified as of 2026-08-26 against each vendor’s public documentation and public repositories. A — means we found no such capability documented at that date — not that the vendor lacks it. Vendors change their products; if anything here is inaccurate or out of date, please open an issue and we will correct it.
