Pros	Drop-in localhost proxy means zero code changes to integrate Claims 87% token reduction with lossless retrieval Apache 2.0, free for commercial use, on PyPI and npm Native integrations for LangChain, Agno, Strands, and MCP Provider-agnostic via LiteLLM, including Bedrock and Vertex	Apache-2.0 licensed and pip-installable, runs fully self-hosted Visual canvas plus Python escape hatch, no lock-in to a DSL Built-in test cases and failure inspection, not an afterthought Agents export as JSON so they diff cleanly in git
Cons	Young project; production track record is thin Benchmark numbers are self-reported and need independent validation Adds a proxy hop and another moving part to your inference path Documentation depth varies across the six compression algorithms	Managed cloud and official SDKs are still on the roadmap Smaller ecosystem than LangGraph or LlamaIndex Visual builders can hide complexity that bites at scale
