Full Prompt Packing pipeline
Deterministic Prompt Packing for every request — selects, reduces, and structures context into a Pak before it hits the wire. The OSS package is the full pipeline, not a limited demo.
Open source · beta
TokenPak is open source.
The proxy, Prompt Packing engine, client integrations, local dashboard, Savings Ledger, and Spend Guard are Apache 2.0 licensed and run entirely on your machine. This is the beta surface — features that ship today, no marketing of anything that doesn't.
Install
pip install tokenpak
tokenpak setup
One command to install, one to set up. The setup wizard detects API keys,
picks a compression profile, and starts the proxy on
127.0.0.1:8766.
What's in the OSS beta
Local proxy, no cloud
Runs at 127.0.0.1. Byte-preserved passthrough; your prompts and credentials stay in your environment and the provider flow you already use.
Nine client integrations
Claude Code, Cursor, Cline, Continue, Aider, OpenAI SDK, Anthropic SDK, LiteLLM, Codex.
Savings Ledger + Spend Guard
Local telemetry store, A/B replay, 50 built-in compression profiles, semantic vault indexing, and a pre-send circuit breaker (Spend Guard) that blocks runaway requests before they reach the provider.
