Manifest
Manifest is an open-source LLM router for OpenClaw that analyses each query locally and routes it to the most cost-effective model capable of handling it — cutting costs while keeping data private.
About
Manifest is an open-source LLM router that sits between OpenClaw and your model providers, analysing each incoming query locally to determine the most cost-effective model capable of handling it accurately. Rather than sending every request to a large expensive model, Manifest routes simpler queries to cheaper options and reserves the capable models for tasks that genuinely need them. Data privacy is maintained because analysis happens locally — queries aren't sent to a third-party routing service. The result is a meaningful reduction in API spend without requiring any changes to agent logic. Setup is designed to be fast with minimal friction, making it practical to trial and compare routing strategies before committing.
Teams and developers running OpenClaw at scale who are looking to reduce LLM API costs without sacrificing output quality or compromising data privacy — particularly those currently routing all traffic to a single expensive model and willing to adopt intelligent routing in exchange for lower spend.
Pros & Cons
Pros
- check Local query analysis preserves data privacy — no queries sent to a third-party service for routing decisions
- check Cost reduction through intelligent routing can be substantial for workflows that currently send all requests to expensive models
- check Open-source MIT-licensed code means it can be audited, modified, and self-hosted
- check Transparent proxy design requires no changes to existing agent code
- check Fast setup supports quick piloting and cost comparison before full deployment
Cons
- close Routing quality depends on the local analysis model's accuracy — misrouting a query to an insufficient model degrades output quality
- close Open-source project without a managed cloud offering means self-hosting and maintenance overhead
- close Cost savings vary significantly by workload; teams with already-optimised model selection may see limited benefit
