You are deciding where to run OpenClaw for your team. Self-host on a cheap virtual server, use a managed host, or keep it on someone's laptop. The software is free, so the decision looks like a small one. It is not, because the free part is under 10% of what you will actually pay.
This page sets out the real numbers: what hosting costs, what the language-model bill looks like at each usage level, what UD's OpenClaw Express plans cost in Hong Kong dollars as of 21 August 2026, and where a different option is the better buy. Prices below were verified on the live UD product page on the date of publication.
How much does it cost to run OpenClaw per month?
OpenClaw itself is free and open source. Total monthly cost is hosting plus language-model API spend. Hosting runs from HK$0 on reused hardware to roughly HK$1,600 for a managed enterprise-grade server. Model spend ranges from zero on local models to over US$260 a month on frontier models with default settings.
The two lines on your bill
--- Hosting. Where the agent loop runs, 24 hours a day. Fixed and predictable.
--- Model API spend. What the agent pays every time it thinks. Variable, and the line that surprises people.
According to Kilo's April 2026 cost breakdown of real operator spend, the language-model bill is 90% or more of total cost for most setups, and most experienced operators land between US$20 and US$50 a month by routing routine work to cheap models.
The same analysis records a single operator running identical workloads across six models for three weeks. Extrapolated to a month: Opus 4.7 at US$261, Sonnet 4.6 at US$84, GLM-5.1 at US$31, MiniMax M2.5 at US$4, and a local Qwen 3.5 9b at US$0. Same agent, same tasks. That spread is a configuration decision, not a vendor decision.
What does UD OpenClaw Express cost?
UD OpenClaw Express is a fully managed OpenClaw deployment on Hong Kong cloud servers, with two published plans. Starter is HK$220 per month, listed from HK$488. Pro is HK$580 per month, listed from HK$1,288. A limited-time code, new2026, is advertised on the product page for 50% off.

What is the total first-year cost, worked out?
Take a mid-market Hong Kong team running two agents with mixed model routing. On the Pro plan at HK$580 a month, hosting is HK$6,960 a year. Model spend at the typical US$35 a month adds roughly HK$3,276. Total first-year cost lands near HK$10,236, or about HK$853 a month all-in.
Three worked scenarios, using an indicative rate of HK$7.8 to the US dollar
--- Scenario A, single user testing. Starter at HK$220 a month is HK$2,640 a year. Model spend on a free tier or a US$10 subscription adds HK$0 to HK$936. First-year total: HK$2,640 to HK$3,576.
--- Scenario B, departmental deployment. Pro at HK$580 a month is HK$6,960 a year. Mixed routing at US$35 a month adds HK$3,276. First-year total: approximately HK$10,236.
--- Scenario C, premium models left on defaults. Pro at HK$6,960 a year, plus frontier-model spend at US$200 a month, adds HK$18,720. First-year total: approximately HK$25,680. Hosting is 27% of the bill. Configuration is the rest.
The lesson from those three rows is that the plan you choose moves the bill by a few thousand Hong Kong dollars a year. The models you route to move it by tens of thousands. Any cost conversation that stops at the hosting line is looking at the wrong number.
Is self-hosting cheaper?
In dollars, yes. A budget virtual server that runs OpenClaw around the clock costs US$4 to US$10 a month, roughly HK$31 to HK$78. That is materially below any managed plan. The cost you take on instead is operational, and it is not small.
What self-hosting transfers to your team
--- SSH keys, firewall rules, operating-system updates, Docker, reverse proxy and TLS certificates.
--- Gateway binding. An OpenClaw gateway reachable from the public internet is a live security exposure, not a configuration preference.
--- Version updates and the reboots that follow when OpenClaw or the OS pushes a change.
--- Log rotation, backups, monitoring, and someone available when the agent stops at 3am.
Kilo's analysis puts the honest version plainly: self-hosting is cheaper at steady state if you do the audit, and more expensive if you forget, which most operators do at least once. The specific failure it documents is a new user who pointed an idle agent at a frontier model, left the default 30-minute heartbeat running, and was billed about US$5 a day for doing nothing at all.
For a 50 to 500 person Hong Kong enterprise, the calculation is not HK$78 against HK$580. It is HK$78 plus a named engineer's time and an unbounded downside, against HK$580 and a support line that answers in Cantonese.
Which plan fits which buyer?
Starter fits one person evaluating whether agents belong in the workflow at all. Pro fits a department running agents other people depend on. Self-hosting fits organisations with an engineer who already owns Linux infrastructure and wants control of the runtime.
The decision, by buyer type
--- An operations manager running a proof of concept alone. Starter, HK$220 a month. 2 vCPU and 4GB RAM is sufficient for a single agent, and the cost is inside most discretionary budgets without a procurement cycle.
--- A department head deploying agents for a team. Pro, HK$580 a month. 6 vCPU and 16GB RAM with enterprise-grade data isolation is the tier positioned for cross-departmental use, and the isolation matters once the agent touches business data.
--- An IT director with existing Linux capability. Self-host on a virtual server. You already own the operational muscle, and control of the runtime is worth more to you than the managed convenience.
--- A COO who needs one accountable vendor and local support. Pro, with the Cantonese and Traditional Chinese support line as the deciding feature rather than the specification.
--- An enterprise needing data residency or on-premises deployment. Neither published plan is the answer. Ask about Private AI BizHub instead, and read our comparison of what private AI and cloud subscriptions each cost a Hong Kong business.
Where does OpenClaw Express not win?
Four honest limitations. There is no published free tier or trial length. There are only two plans, so a team between the two specifications either overpays or under-provisions. Language-model spend is separate and uncapped. And the managed-OpenClaw category now has credible competitors.
Where a different option is the better buy
--- If your budget is under HK$100 a month and you have Linux skills in-house, self-hosting wins outright. A US$5 virtual server does the same job. Pay the managed premium only if you are buying back operational time.
--- If you want managed OpenClaw bundled with existing application hosting, Cloudways wins on consolidation. DigitalOcean's Cloudways launched Managed AI Agents in August 2026, starting with OpenClaw and Hermes, folded into its existing hosting billing and support. If your web estate already sits there, one invoice beats two.
--- If your real problem is unpredictable model spend rather than hosting, a flat-rate gateway subscription wins. Subscription plans in the US$10 to US$19 a month range give a predictable language-model bill. That solves a different line on the invoice than any host does.
--- If you need a governed enterprise agent platform with audit trails and role-based access, neither OpenClaw nor OpenClaw Express is the right category. That is a platform procurement, not a hosting decision.
Stating this plainly is the point. A cost page that concludes one vendor wins every row is an advertisement. The reason to choose OpenClaw Express is specific: you want OpenClaw running reliably in Hong Kong, in three minutes, without hiring for it.
How do you keep the model bill under control?
Three configuration changes do most of the work. Route routine tasks to a cheap model. Pin the heartbeat to a cheap model or lengthen its interval. Keep the agent's memory files small, because every turn re-sends them.
The three changes, in order of impact
--- Split coordinator from worker. A cheap primary model handles heartbeats, memory housekeeping and routine tool calls. A premium model wakes only when reasoning genuinely matters. Kilo's report cites an operator whose spend fell roughly 70% from this change alone, before any routing rules were tuned.
--- Fix the heartbeat. The default fires every 30 minutes on whatever model the agent defaults to, which is 48 billed wake-ups a day whether you use the agent or not. Pin it to a cheap model, lengthen the cadence, or do both and an idle agent costs cents rather than US$5 a day.
--- Control context growth. Every turn re-sends conversation history plus workspace files. A bloated memory file doubles the cost of every subsequent call in the session.
Classify tasks before the call, not after a cheap model fails and retries. Failure-based upgrades push three to four times more traffic to the expensive tier than pre-classification does, which quietly undoes most of the saving.
What is the right next step?
If you are testing whether agents belong in your workflow, take Starter at HK$220 a month and set a model budget before you deploy. If a team will depend on the agent, take Pro at HK$580 a month for the isolation and the specification headroom. In both cases, fix the heartbeat on day one.
The decision that actually determines your bill is not which host you pick. It is which model answers which request, and whether anyone in your organisation owns that configuration. Choose the host that lets your team spend its attention there instead of on TLS certificates.
