About AgentFast

AgentFast is a boilerplate for developers who want to turn an AI prototype into a real product. It supplies the production layer that demos usually skip, such as user accounts, paid plans, API keys, Stripe billing, run logs and a dashboard, so you can focus on prompts, tools and product logic.

The kit is built on Next.js and uses the AI SDK with AI Gateway so a product can route requests across major model providers. It can ship to an embeddable chat widget, an API or signed webhooks from the same codebase. Built-in testing runs against sample payloads and schemas, and an operations dashboard covers logs, analytics, draft and publish controls, and cost visibility. Guardrails include rate limits, token caps, approvals, replay-safe webhooks and row-level security. AgentFast is a commercial product sold as a one-time purchase tier with launch pricing ahead of its public release. Developers begin from an opinionated template and customize the runtime from there.
