The Memory and Control Layer for AI Agents

OpenSink records agent activity, manages human approvals, and provides a real-time timeline of execution — without locking you into any framework.

Works with all major AI frameworks and providers.

Sessions: durable, resumable agent execution

Every agent run is a Session. Sessions track state, handle human approvals, and let agents pause and resume without losing context.

Resumable

Agents can stop, crash, or wait — then resume without losing context

Human-in-the-Loop

Pause for approvals or input, continue exactly where you left off

Full Visibility

Inspect, debug, and audit every agent execution in detail

Durable State

Store execution variables that survive restarts and crashes

OpenSink stores session state — your agent code decides what happens next.

A control layer that stores what matters.

OpenSink gives you visibility into agent execution and a durable place to store the outputs that matter — sessions, decisions, and results.

Not logs.Not traces.Not ephemeral memory.

OpenSink becomes your control plane for agent execution and outputs.

Running agents in production is hard to control.

Without a control layer

  • No visibility into execution state
  • No way to pause for human approval
  • Outputs scattered or lost
  • Hard to debug or audit

Boring by design — reliable in production.

Control how agents operate — anywhere

OpenSink doesn't replace your agents. It gives you a central place to configure and control their behavior.

Sessions & state

Durable execution records that survive crashes and restarts.

Agents store state, pause for human input, and resume exactly where they left off.

This is not observability.

OpenSink stores outputs your system depends on — not telemetry.

Designed for agents. Loved by developers.

import { OpenSink } from "@opensink/sdk";

const sink = new OpenSink({ 
  apiKey: process.env.OPENSINK_API_KEY
});

// Write an item to your sink
await sink.items.create("finance-news", {
  title: "AAPL dropped 3%",
  data: { ticker: "AAPL", change: -3 }
});

// Query items back
const items = await sink.items.list("finance-news");

Agents can discover, read, and write data reliably — without custom glue code.

Who OpenSink is for

Built for you if

  • You're running AI agents in production
  • Agent outputs matter beyond a single run
  • You need reliability, not demos

Probably not for you if

  • You only need logs or tracing
  • You want a no-code agent builder
  • You don't control your backend

Take control of your agents in production.
