Two different agents, one hosting problem
Agent Zero is a general autonomous agent with its own web dashboard. You type a goal, and it plans the steps, writes and runs code, browses with a browser it ships inside its own container, and reports back. The whole stack runs in Docker on your machine.
OpenClaw is an agent you message like a contact. It runs a persistent daemon with a heartbeat scheduler, connects to Telegram, WhatsApp, or Signal, and fires routines on time whether you are online or not. You do not open a dashboard to use it day to day; you text it.
Different interaction models, same infrastructure problem. Both only make sense on a machine that never sleeps. Agent Zero working through a long goal cannot survive your laptop lid closing, and OpenClaw's heartbeat scheduler is pointless on a machine that is off at 3 a.m. Choosing between them means answering two things: which agent fits your work, and where it should run. This article covers both.
How you use each one day to day
Agent Zero is goal-driven. Its web UI shows a chat, plus a live view of the browser and computer the agent is using. The workflow is: open the dashboard, hand it a goal ("research these five competitors and write up a summary", "build and test this script"), watch it work or walk away, and read the report later. It is at its best on self-contained multi-step tasks where you want one agent to plan, execute, and verify without you wiring anything up.
OpenClaw is ambient. After you connect your messaging channels in its Control UI, the agent is just another chat in your phone. You send it tasks the way you would text an assistant, and its heartbeat scheduler runs standing routines in the background: message you a morning summary of the feeds you follow, or ping you when a page you are watching changes. It is at its best as an always-available assistant that lives where you already are, which is your messages.
If you are new to the category, what is an AI agent covers the basics. The short version for this comparison: pick Agent Zero when the unit of work is a goal you hand over, pick OpenClaw when the unit of work is an ongoing conversation plus scheduled routines.
Server requirements: one is fixed, one flexes
Agent Zero has the heavier and less negotiable footprint. It runs its full stack in a Docker container: the agent loop, its tools, and its own browser and computer. The project's own VPS guidance is 2 vCPU and 4 GB RAM, and that is what Hivra provisions it with as a fixed footprint. There is no lighter mode, because the browser and computer ship inside the container whether or not a given task uses them.
OpenClaw scales with what you turn on. The daemon and heartbeat scheduler are the light part: on Hivra an OpenClaw box starts at 1 vCPU and 2 GB RAM, and switching browser automation on adds another 1 vCPU and 2 GB. If you self-host with the full Docker setup instead, budget more: our OpenClaw self-hosting guide recommends 2 vCPU and 4 GB as the DIY minimum, because the multi-container install competes with everything else on the box.
The browser difference matters more than the raw numbers. Agent Zero's browser is its own, inside its container, visible in its dashboard, with no extra setup. OpenClaw's optional browser works differently: turn it on and OpenClaw gets a real Chrome running on the same box, with a live browser view where you log into your accounts once. After that, the agent acts inside those sessions. Self-contained browsing versus browsing as you, in your accounts. Which one you want depends on the tasks.
The security part nobody budgets for
Both agents ship a web UI, and a web UI on a server is a thing you have to protect. This is not hypothetical for OpenClaw: in February 2026, Bitsight researchers found over 30,000 self-hosted OpenClaw instances exposed to the public internet without authentication, mostly through misconfigured reverse proxies. A one-click remote code execution flaw, CVE-2026-25253, was disclosed the same week and patched in v2026.1.29. An autonomous agent with shell access and your credentials is one of the worst possible things to leave open.
Agent Zero has the same shape of risk. Its dashboard is the control surface for an agent that writes and runs code, so exposing it unauthenticated hands that power to anyone who finds the port.
Self-hosting either agent means owning this: a reverse proxy you configure correctly, authentication you bolt on, and updates you apply on the project's schedule, which for OpenClaw means one or two major releases a month.
Managed hosting closes this gap by default: on Hivra each agent's UI binds to its own private VM and only an authenticated gateway reaches it. The trade-offs of doing this yourself versus paying someone are covered in managed vs self-hosted AI agents.
What hosting actually costs
DIY on a VPS. A 1 vCPU, 2 GB box for a browserless OpenClaw runs about $5 to $10 a month. The 2 vCPU, 4 GB box that Agent Zero needs, or OpenClaw with the browser on, runs about $10 to $20 a month. Add your time: install, reverse proxy, auth, updates, and the occasional 2 a.m. restart. The cost of running an AI agent breaks this down in detail.
Dedicated agent hosts. Services that specialize in running OpenClaw for you typically list $29 to $49 a month for a single always-on instance, with the security setup handled for you.
Hivra. Both agents run on the Pro plan at $9.99 a month: up to 3 agent slots, a compute pool of 2 vCPU and 4 GB RAM, and the UI kept private with no setup on your side. The box provisions in a few minutes.
Model usage is the one cost hosting never includes, for anyone. Both agents need an LLM to think with, and model spend is often the larger number: a few dollars a month for light use, $50 or more for heavy daily work, depending on the model you pick. On Hivra a managed model (DeepSeek V4 Pro through Venice) is pre-configured at launch so the agent responds immediately, and you can switch to your own provider any time: in the Control UI for OpenClaw, in Settings for Agent Zero. Keys you set there stay on your box, and Hivra adds no markup on model usage.
Which one should you host?
Host OpenClaw if your agent's job is to be reachable and punctual: answer you in Telegram, WhatsApp, or Signal, run morning routines on its heartbeat, watch things while you sleep. It is lighter on the server, and its messaging-first design keeps it in a surface you already check daily. Start at the OpenClaw page.
Host Agent Zero if your agent's job is to take a goal and go: multi-step research, tasks that need code written and run, work where watching the agent's browser and computer from one dashboard beats stitching tools together. Start at the Agent Zero page.
Genuinely unsure? Pick the one that matches where your work lives. If your day runs through messaging apps, OpenClaw will get used and a dashboard agent will not. If you have a backlog of hand-off-able projects, that is Agent Zero's home turf. For the wider landscape beyond these two, the AI agent hosting guide compares the main options.
Running both, and the fastest way to try either one
Plenty of people end up wanting both: OpenClaw as the standing assistant, Agent Zero for hand-off projects. DIY, that is one 4 vCPU, 8 GB VPS at roughly $20 to $40 a month, running the two side by side.
On Hivra, one plan detail matters before you pick. The Pro plan has 3 agent slots, but its compute pool is 2 vCPU and 4 GB RAM shared across everything you run, and Agent Zero's fixed footprint is exactly 2 vCPU and 4 GB. On Pro, Agent Zero fills the entire pool by itself, so you cannot run OpenClaw next to it at the same time. Running both side by side takes the Power plan at $19.99 a month: a 4 vCPU, 8 GB pool that fits Agent Zero plus OpenClaw with its browser on, using the pool exactly. A stopped box still holds its share of the pool; deleting a box is what frees it, immediately, so switching between agents costs a couple of minutes, not a support ticket.
If you want to skip the setup entirely, either agent launches on Hivra in a few minutes: pick one on the agents page, name the box, and it comes up ready to work. If the agent does not earn its keep, delete the box and the experiment cost you one month and zero evenings.
