modbender OpenClaw Switch
The missing model manager for OpenClaw. Switch models, visualize fallback chains, and manage multi-provider setups.
Quick start
# Show current model, fallback chain, heartbeat & subagent config
bash {baseDir}/scripts/openclaw-switch.sh status
# List all available models across all providers
bash {baseDir}/scripts/openclaw-switch.sh list
# Switch primary model (by number from list)
bash {baseDir}/scripts/openclaw-switch.sh switch 2
# Show fallback chain only
bash {baseDir}/scripts/openclaw-switch.sh fallback
How it works
OpenClaw natively supports model.fallbacks — when the primary model returns an error (429, 500, etc.), the next model in the chain is tried automatically. OpenClaw Switch helps users configure, visualize, and toggle this chain.
Typical setup
Register multiple providers in openclaw.json, each with its own API key:
{
"models": {
"providers": {
"provider-a": { "apiKey": "...", "models": [{ "id": "model-1" }] },
"provider-b": { "apiKey": "...", "models": [{ "id": "model-2" }] }
}
},
"agents": {
"defaults": {
"model": {
"primary": "provider-a/model-1",
"fallbacks": ["provider-b/model-2"]
}
}
}
}
Use cases
- Same provider, two API keys (e.g. paid + free Gemini) — register as separate providers
- Cross-provider failover (e.g. Gemini → OpenAI → local Ollama)
- Cost optimization — route heartbeat/subagents to cheaper or free models
Security
The bundled script:
- Never transmits API keys or config data over the network
- Never logs full API keys (masks all but first 8 chars)
- Uses only
