An open-source TypeScript framework for building LLM agents as XState state machines, with explicit control flow, model decisions, tool effects, testing, visualization, and runtime state management.
Prices and medians update for the tier you select.
Ranked by how closely each one matches Stately Agent's job. Prices show each provider's Pro state; entry prices are labelled as such. Unpriced products still belong to the market.
Market = the products most similar to this one by capability; prices are median / quartiles over its priced members, separated by provider type and buyer tier.
