How TokenPak compares.
We get asked how TokenPak stacks up against the other LLM proxy, gateway, and observability tools. This page is an honest summary. Every row cites a public source or a reproducible benchmark — if something isn't cited, we don't claim it.
Comparisons reflect public documentation as of 2026-04-23. Competitor products evolve — if something below becomes outdated, write to hello@tokenpak.ai and we'll update the row.
Where TokenPak is different
Your prompts, responses, and keys stay on your machine. No cloud ingestion, no SDK telemetry, no account required to run. The only telemetry TokenPak emits is the opt-in debug logging disclosed in the privacy page — and even that stays local.
The 30–50% reduction headline is pinned to a fixture in CI (`make benchmark-headline` in the OSS repo). Every PR is gated on the floor; anyone can reproduce the number on their own machine.
Savings attribution is causal — proxy-caused hits are never mixed with provider-side cache hits. The Pro tier turns budgets into hard 429s rather than passive dashboards.
Feature-by-feature
TokenPak column describes the OSS proxy unless explicitly marked Pro.
| Feature | TokenPak | Helicone | LangSmith | LiteLLM | Portkey | Langfuse | OpenRouter |
|---|---|---|---|---|---|---|---|
| Runtime shape | Local proxy on 127.0.0.1. Byte-preserved passthrough. | Managed SaaS proxy (proxy your requests through helicone.ai). | SDK + hosted observability backend. | Library + optional proxy server. | Managed gateway with hosted control plane. | Self-hostable or cloud observability backend with SDKs. | Hosted model router; requests route through openrouter.ai. |
| Data-exit posture (default) | Nothing leaves your machine except the request you were already sending. | Request bodies + responses flow through Helicone by design. | Traces shipped to LangSmith (hosted) by SDK default. | Local by default in library mode; proxy forwards to provider. | Traffic through Portkey gateway. | Traces shipped to backend (self-hosted or cloud). | All traffic through OpenRouter. |
| Compression / context reduction | Deterministic pipeline. Up to 90%+ on direct-API/CLI/uncached; ≥30% floor pinned in CI on an agent-style fixture. Provider-cached flows (Claude Code) show lower incremental savings — the provider cache already absorbs most of the token pool. | No compression feature documented. | Observability tool; not a compression product. | Caching + prompt-management; no compression pipeline. | Configurable gateway transforms; not a compression pipeline. | Not a compression product. | Router; not a compression product. |
| Cost tracking | Per-request SQLite ledger with causal attribution. OSS. | Yes (hosted dashboard). | Yes (hosted observability). | Yes (lightweight, library-level). | Yes (hosted). | Yes (cost tracking in observability backend). | Yes (account-scoped). |
| Budget enforcement (hard 429 on cap) | Pro tier — budgets map to hard 429 responses at request time. | Rate limits available; budget enforcement not the primary framing. | Observability, not enforcement. | Rate-limit primitives; no budget-to-429 framing documented. | Rate limits + guardrails available (hosted). | Observability, not enforcement. | Per-key credit limits. |
| License + pricing | OSS proxy Apache-2.0. `tokenpak-paid` (Pro tier) via license-gated private index. | OSS core + commercial cloud plan. | Commercial. | MIT; commercial support available. | Commercial (hosted) with SDKs. | OSS core (MIT) + commercial cloud + enterprise. | Commercial. |
Reproduce the benchmark floor
The ≥30% compression floor in the Compression row is pinned in CI on an agent-style fixture. On favorable direct-API / CLI / uncached workloads measured savings routinely reach 90%+. Clone the OSS repo and run:
git clone https://github.com/tokenpak/tokenpak
cd tokenpak
make dev
make benchmark-headline
The benchmark test runs on every PR under the headline-benchmark
(blocking) CI gate; any PR that drops the reduction below 30% on the pinned
fixture fails the gate. The 90%+ upper-end is what favorable uncached workloads
measure on the same fixture with the full pipeline engaged — the pinned floor is
the minimum promise, not the ceiling.
