Compare
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 Competitor products evolve — if something below becomes outdated, write to hello@tokenpak.ai and we'll update the row.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 headline reduction is pinned to an agent-style fixture in CI (`make benchmark-headline`) and gated on every PR — reproduce the current number yourself.
Savings attribution is causal — proxy-caused hits are never mixed with provider-side cache hits. Spend Guard catches runaway requests before they reach the provider, returning HTTP 402 with a release directive instead of letting a single agent burn through a budget.
Feature-by-feature
TokenPak column describes the OSS beta as it ships today.
| 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; optimizes the user-controlled token pool. Reduction pinned to an agent-style CI fixture (reproduce with `make benchmark-headline`). Provider-cached flows (Claude Code) show lower incremental savings. | 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). |
| Pre-send spend control (Spend Guard) | OSS — pre-send circuit breaker with rolling caps. Blocks before the request reaches the provider and returns a release directive. | Rate limits available; pre-send budget enforcement not the primary framing. | Observability, not enforcement. | Rate-limit primitives; no pre-send budget enforcement documented. | Rate limits + guardrails available (hosted). | Observability, not enforcement. | Per-key credit limits. |
| License | Apache 2.0 — full package, no gated features in the OSS beta. | OSS core + commercial cloud plan. | Commercial. | MIT; commercial support available. | Commercial (hosted) with SDKs. | OSS core (MIT) + commercial cloud + enterprise. | Commercial. |
Reproduce the headline benchmark
The reduction shown in the Compression row is pinned by a CI
regression gate on a fixed agent-style fixture — run make benchmark-headline
to see the current value. On favorable direct-API / CLI / uncached workloads it can
reach up to 90%+. Clone the OSS repo and run:
git clone https://github.com/tokenpak/tokenpak
cd tokenpak
make dev
make benchmark-headline
The benchmark runs on every PR under the headline-benchmark
(blocking) CI gate, which pins a minimum reduction on the fixed agent-style
fixture. These are fixture measurements you can reproduce — not a guaranteed savings
promise; your results vary by workload and provider cache.
