You want a browser-driving AI agent that does not go off the rails in production. The kind that opens a site, fills a form, scrapes a result, and behaves the same way the next time it runs. OpenClaw on FlowEngine is built for that. This guide walks through provisioning your first OpenClaw instance end-to-end, from clicking Deploy to seeing the agent come online.
Skill level: intermediate. Time required: about 10 minutes, most of it watching the deploy run. You will need a FlowEngine account, a card on file, and a rough idea of what you want the agent to do.
What You'll Build
By the end of this guide you will have a running OpenClaw instance under your FlowEngine account. OpenClaw is FlowEngine's deterministic AI agent runtime. It ships with a managed headless browser, a set of channel adapters (Telegram, Slack, Discord, WhatsApp), and gVisor sandboxing so each agent run is isolated at the kernel level.
The point of OpenClaw is reproducibility. n8n is great for flexible visual workflows. OpenClaw is the right tool when the same input has to produce the same output every time. Compliance checks, invoice extraction, scheduled scraping, regulated form fills - things where a hallucinating agent is a real problem.
Before You Start
- A FlowEngine account. Sign up at flowengine.cloud if you do not have one. The free tier covers personal n8n hosting; OpenClaw runs on the 30 GB tier or higher, so you will pick that during checkout.
- A card on file. The deploy flow opens Stripe checkout the first time you buy a slot. After that, FlowEngine bills the same card.
- An idea of what the agent should do. You can configure the goal after deploy, but it helps to have one written down. Something like: "Open hackernews.com, return the top 5 story titles and their points."
Step 1: Buy a Slot
Sign in to FlowEngine, click Hosting in the left sidebar, then hit + Deploy. The New Instance modal opens. Set three things:
- Instance Name. Use something specific.
research-botreads better in logs thanInstance 2a month from now. You can rename it later. - Storage tier. Pick 30 GB or 50 GB. OpenClaw will not deploy on a 10 GB slot.
- Billing. Annual saves 20% versus monthly. If you are testing, monthly is the lower-commitment option. You can switch from the instance detail page later.
Click the checkout button. You land on Stripe; pay or confirm the existing card, and Stripe redirects you back to FlowEngine.
Step 2: Pick OpenClaw on the New Instance
After the redirect, FlowEngine routes you to the new instance's detail page. The slot exists but has no service running on it yet, so the page shows a service-type picker with four tiles.
The four options:
- n8n - workflow automation platform.
- OpenClaw - managed AI agent with browser, channels, and gVisor sandboxing.
- Hermes Agent - chat-only AI agent for Telegram, Slack, Discord, WhatsApp.
- Docker - bring your own public image with env vars and auto-SSL.
Click the OpenClaw tile, then click Deploy. The slot flips into a Deploying state. Provisioning takes about five to six minutes. The page refreshes itself; you do not need to babysit it.
Step 3: Wait for the Active Badge
While the agent boots, FlowEngine wires up a few things in the background: the headless browser, the gVisor runtime, the agent's data volume, and a default LLM connection through the FlowEngine AI proxy with Claude Sonnet 4.6 as the primary model. The Stripe billing record is also linked to the instance so usage rolls up to the right invoice.
When the green Active badge appears, the agent is online. A few cards on this page are OpenClaw-specific:
- Open OpenClaw. Opens the agent's web UI in a new tab. This is where you write the system prompt, wire up channels, and run a goal.
- AI Model. The model the agent runs with. Defaults to Claude Sonnet 4.6 against the FlowEngine AI proxy, swappable from this dropdown. Saving restarts the agent.
- Run Doctor. A diagnostics check on the live instance. Useful when something looks off and you want a one-click health report.
- Gateway Token + WebSocket URL. Under Advanced. These are how external services authenticate to the agent over WebSocket. Keep the token secret.
Quick Actions (Stop, Restart, Update & Redeploy) and the live CPU, memory, and disk cards work the same as on any FlowEngine instance.
Step 4: Configure the Agent in the OpenClaw UI
Click Open OpenClaw. The agent's own web UI opens at the instance URL. This is where the agent's actual job lives. The minimum useful config:
- A goal or system prompt. A paragraph or two describing what the agent should do. Be specific. "Visit example.com/orders, extract every row newer than 24 hours, and post a CSV to Slack." Vague prompts produce drift.
- Channels (optional). Bot tokens for Telegram, Slack, Discord, or WhatsApp, if you want a human to kick off runs or chat with the agent. Skip if it only runs on a schedule.
- Schedule (optional). A cron expression for unattended runs.
Save in the OpenClaw UI. The first run kicks off when you trigger it from a channel or when the schedule fires.
Step 5: Verify the First Run
Two ways to verify. From the FlowEngine portal, click Run Doctor on the instance detail page for a quick health report. From the OpenClaw UI itself, trigger a run and watch the live trace; OpenClaw streams every browser action and tool call in order, which is the deterministic execution log you came here for.
If the run fails, the most common causes are:
- Channel token wrong or revoked. The agent surfaces the auth error in its run trace. Re-issue the token from Telegram BotFather, the Slack admin console, or the Discord developer portal, and paste it back into the channel field.
- Goal too vague. The agent stalls or returns an empty response. Tighten the goal with concrete steps and an explicit success condition.
- Browser blocked by the target site. Some sites detect headless. OpenClaw's browser looks like a normal Chromium session, but a few sites still block it. Switch the agent to a public API for that source if one exists.
Once the first run completes cleanly, the rest is iteration. The agent's behavior is reproducible, so once a run works it will keep working on the same input.
Common Mistakes
- Buying the 10 GB tier. OpenClaw will not deploy on a 10 GB slot. You find out on the service-type picker when the OpenClaw tile shows a "Requires 30GB plan" badge. Pick 30 GB or higher in the New Instance modal.
- Skipping the goal. A blank goal produces a confused agent. Even a one-paragraph spec is better than nothing.
- Treating OpenClaw like n8n. n8n is the right tool for "connect this app to that app" wiring. OpenClaw is for goal-driven runs where the agent decides the steps. If your task is a fixed pipeline of API calls, deploy n8n on a separate slot instead.
- Adding too many channels at once. Wire up Slack first, get one clean run, then add Telegram or WhatsApp. Multi-channel debugging in one go is painful.
Going Further
FlowEngine lets you run n8n and OpenClaw side by side, on separate instances under the same account. A common agency setup is one OpenClaw instance per client for goal-driven research and one n8n instance per client for fixed workflows, both white-labelled under the agency's brand. Cross-link is easy: the n8n instance can call the OpenClaw HTTP endpoint as a node, and the OpenClaw agent can post results back into n8n.
If you are coming from LangGraph, CrewAI, or AutoGen, the mental model shift is "stop coding the agent, start configuring it." OpenClaw owns the runtime so you do not write retry loops, browser launchers, or memory stores. You write the goal and the channel; it handles the rest.
For the n8n side of the agency stack, our guide to spinning up your first n8n instance walks through the equivalent flow for n8n. The two posts together cover both halves of the FlowEngine deploy story.
Wrapping Up
You provisioned an OpenClaw instance, picked a service type, watched it come online, and ran a first goal. The agent is now an addressable URL under your FlowEngine account, with logs, billing, and lifecycle controls in the same place as your other instances.
For tasks where you need guaranteed reproducible results - invoice processing, compliance checks, scheduled scraping - OpenClaw's deterministic agents are the right tool.
