Free tools / client-side only
Free multi-agent architecture tools
Use these browser-only tools to make the three practical calls behind a multi-agent system: whether to split, which pattern fits, and whether the cost is defensible.
when to use multiple agents
Do You Need Multiple Agents?
Answer a short questionnaire and get a single-agent vs multi-agent verdict with a recommended orchestration pattern.
Open tool
agent orchestration patterns
Agent Orchestration Pattern Picker
Rank orchestrator-worker, pipeline, debate, swarm, and judge-panel patterns against latency, cost, reliability, and task constraints.
Open tool
multi agent cost calculator
Multi-Agent Cost Estimator
Estimate multi-agent run cost from agents, tokens, turns, model price, and coordination overhead, then compare it with a single-agent baseline.
Open tool
Suggested workflow
- Use the decision quiz to decide whether a split is even worth testing.
- Use the pattern picker to choose the smallest orchestration pattern that fits the constraints.
- Use the cost estimator to compare token spend with a single-agent baseline.
Do these tools send data to a server?
No. Each tool runs client-side in the browser. Inputs are used only for the calculation or recommendation shown on the page.
Which tool should I start with?
Start with the decision quiz. If it recommends a split, use the pattern picker next, then run the cost estimator before prototyping.
Are the tools vendor-specific?
No. They are architecture tools for multi-agent LLM systems regardless of model provider.
