Make money with Duraton.ai. Duraton is where anyone builds an AI agent without writing code - so you can turn it into something people pay for. Have a problem AI can solve? Build the agent, no coding required. Every other builder shows you a chat log. Duraton shows you the reason to trust what your agent did: | Check | What it means | | - | - | | **Step record** | every action your agent took, in order - not just its final answer | | **Approval before it happens** | the risky ones park on a person's decision before they run | | **Replay** | re-run any completed run and see exactly what happened | [Build your first agent](/start/first-agent) in the console - no code. Sign in, add a model provider key, and publish an agent from the console. `agent()` and `tool()` in code: an agent whose every turn and tool call is a durable step. Durable model calls, approvals, guardrails, spend caps, streaming, and observability. The durable runtime, the TypeScript SDK, the REST API, and the protocol a runner speaks. ## Building with code The agent kit and the durable runtime underneath it are also available directly in code - the same document a no-code agent publishes, authored by hand instead. Find the sentence closest to your own problem. | What you want | Where to go | | - | - | | "It must not act without a human on the risky stuff" | [Approvals](/ai/approvals): park the run on a person's decision, holding no worker | | "My agent spends money and I can't sleep" | [Cost controls](/ai/cost-controls): halt before the call that would overspend, or pause over a rolling window | | "My long agent dies halfway and starts over" | [Durable execution](/core/durable-execution): why a run resumes instead of restarting | | "The model is down and my agent just fails" | [Cost controls](/ai/cost-controls): advance to the next model, and cache repeats at zero spend | | "I want to see what it's doing right now" | [Watching a run](/core/realtime) and [Streaming](/ai/streaming): every step and token, live | | "I need to show someone what the agent did" | [AI observability](/ai/observability): token and cost rollups read from the durable record | | "I want to write the agent, not the loop" | [Agent kit](/agent-kit): `agent()`, `tool()`, approval-gated tools, structured output | ### Running anything else durably The model call is optional. If you came here with an ordinary backend job rather than an agent, start here. | What you want | Where to go | | - | - | | "My background job dies halfway and starts over" | [Durable execution](/core/durable-execution): each step is saved when it completes, and the job resumes at the next one | | "I need this to run on a schedule" | [Cron triggers](/core/triggers#cron-triggers): a schedule with no event behind it at all | | "A flaky API keeps killing the whole job" | [Retries](/core/retries): only the failing step retries; the ones before it keep their results | | "It has to wait hours or days for something" | [Steps](/core/steps): the run suspends holding no worker, and survives a restart while it waits | | "The same job must not run twice for one input" | [Idempotency](/core/flow-control#idempotency): collapse repeats into a single run | | "Too many jobs at once, and I'm rate-limited" | [Flow control](/core/flow-control): concurrency, throttle, rate limit, debounce, batch, priority, singleton | | "A job failed and I need to re-run it" | [Control API](/reference/api/control): replay a finished run, or retry from the exact step that failed | ### Getting work in and out | What you want | Where to go | | - | - | | "The work arrives from somewhere else" | [Integrations](/integrations): events, webhooks, or a schedule | | "I need to receive a webhook from a third party" | [Webhooks](/integrations/webhooks): a signature-verified POST becomes an event that starts a run | | "Something has to happen when it finishes" | [Outbound webhooks](/integrations/webhooks#ctx-webhook-send): signed delivery, retried, every attempt logged | | "My agent should be able to operate Duraton" | [MCP server](/integrations/mcp-server): list and control runs, send events, decide approvals | Or work straight through the [recipes](/start/recipes): one complete, paste-and-run workflow per task.
