Freemium

Open-source TypeScript platform for durable AI agents and long-running workflows with no timeouts, plus queues, retries, and observability.

No-timeout task runtime: Tasks run for as long as they need — hours if necessary — unlike Lambda or Vercel functions, making it usable for long-running agents and heavy batch jobs.
Durable AI agents: Chat agents survive tab closes, refreshes, redeploys, and crashes because their execution state is checkpointed by the platform.
Streaming to the frontend: Stream tokens or intermediate step output straight to your UI with no extra API routes to build or maintain.
Tool calling and human-in-the-loop: First-class primitives for LLM tool calls and for pausing runs on human approval before continuing.
Queues, retries, idempotency: Built-in job queues, retry policies, and idempotency keys so you don't hand-roll reliability around every AI call.
Self-host or managed cloud: Apache 2.0 core with a documented self-hosting path, plus a managed cloud for teams that want elastic scale without ops.

Long-running chat agents: Support or research chat agents that keep working across sessions and stream results back to the browser once the user returns.
Multi-step LLM pipelines: RAG pipelines that fan out to hundreds of documents, retry failed calls, and finish minutes or hours later without a client staying connected.
Human-in-the-loop workflows: Agents that draft output, pause for a human approval step in Slack or a web UI, and resume automatically once approved.
Batch AI processing: Nightly jobs that classify, embed, or transform thousands of records with automatic queueing and observability.
Backend for autonomous agents: Serves as the durable execution layer for autonomous agents built with the OpenAI Agents SDK, Vercel AI SDK, or custom orchestration.
