Best VPS for Hermes Agent in 2026

The short answer

Buy a 2 vCPU / 4 GB RAM x86 Linux VPS with 40 GB or more of SSD or NVMe. It is twice the recommended memory for a single-user Hermes Agent, so browser automation and busy turns never push the box into swap. You do not need a GPU. If you want the cheapest thing that still works, a 2 GB plan is fine for a chat-only bot. Everything below explains why, and what each provider charges today.

The same advice applies to OpenClaw, the other framework OpenClaw Launch hosts. Differences are covered in a dedicated section further down.

What Hermes Agent actually needs from a VPS

Hermes Agent, from Nous Research, runs on Linux, macOS, Windows and Termux. Its platform support page puts Linux and WSL2 on both x86_64 and aarch64 in the highest support tier, so an Arm VPS is a legitimate choice. On macOS, Apple Silicon is the top support tier, and Intel Macs are covered by a separate x64 desktop bundle and the CLI install — so an old Intel Mac can work as a home host, though a VPS is still the simpler way to stay online 24/7.

The sizing figures that matter come from the official Docker documentation:

The same page says to allocate at least 2 GB when browser automation is active, and that Playwright needs shared memory (--shm-size=1g). The image ships full Chromium, so the browser toolset costs disk as well as RAM. The installer also pulls in Node.js, ripgrep, FFmpeg and Chromium for you, so budget more disk than the 500 MB minimum suggests. We measured memory on our own fleet and cover it on the system requirements page: idle agents are tiny, and the figure to size against is the peak on a busy turn.

Our rule of thumb follows from that. Chat-only, one user: 2 GB. Browser toolset on, or any plan to run extra services on the same box: 4 GB. A 1 GB VPS technically meets the minimum, but it leaves nothing for the OS, Docker and a busy turn at once.

Why you almost certainly do not need a GPU

With an API provider such as OpenRouter, Anthropic or OpenAI, the model runs on the provider's hardware. Your VPS runs the agent loop, the messaging gateway, cron jobs and tools, and makes outbound HTTPS calls. That is why Nous describes Hermes as deployable on a “$5 VPS” as well as GPU clusters. A GPU instance would add cost and no speed for this setup.

The exception is local inference. If you want to run open-weight models yourself through Ollama or vLLM, you need a machine with enough GPU memory for the model, which is a different product category with a very different price tag. Even then the agent and the model server can live on different machines, so the cheap VPS still hosts Hermes while the GPU box serves the model. See Hermes Agent with Ollama and Hermes Agent on a cloud GPU.

VPS plans compared (October 2026)

Prices checked October 7, 2026 on each vendor's own pricing page or public pricing feed, in the currency the vendor shows. Hetzner's feed lists prices before VAT, and Contabo says its price includes applicable taxes; for the other vendors check the tax treatment at checkout. Cheap headline prices often require a long term, so check the “Term” column.

Two caveats on this table. First, Hetzner's cheaper CX and Arm CAX plans were showing as unavailable with no price on the cost-optimized page when we checked, so we left them out rather than quote an old number. Second, the long-term plans are cheaper per month because you commit up front. Hostinger's renewal rates are roughly double the introductory ones, and Contabo's price is an introductory rate for the first 24 months, and OVHcloud's assumes you pay for a year up front.

Our picks

• Cheapest that is still comfortable: OVHcloud VPS-1. Four gigabytes of RAM and two vCores for $4.54 a month is the lowest price we found with real headroom. You pay annually, so it is a commitment, not a trial.
• Best overall for most people: a month-to-month 2 vCPU / 4 GB plan from Hetzner, Vultr, DigitalOcean or Akamai. You pay more per month than the long-term deals, but you can resize or delete the server without losing a prepaid term, which matters while you are still learning what your agent needs. Vultr is the cheapest of the four at $20; Hetzner CPX22 (€19.49 before VAT) is similar once converted to dollars, and suits readers who want EU data centres. Per-provider walkthroughs: Hetzner, DigitalOcean, Hostinger. This is our judgment on price and flexibility, not a benchmark of CPU or network quality.
• Best free option: Oracle Cloud Always Free. Oracle's documentation lists Ampere A1 allocation of 1,500 OCPU hours and 9,000 GB hours a month, equivalent to 2 OCPUs and 12 GB running continuously, and Hermes supports aarch64 Linux. The catch is in the same document: instances are treated as idle and reclaimable if, over 7 days, CPU and network utilization stay under 20% (and memory under 20% on A1 shapes), and you can hit an “out of host capacity” error when creating one. A mostly idle agent can look exactly like an idle instance. Fine for experiments, risky for a bot you depend on.
• Best for US versus EU latency: pick the region nearest you, but do not over-think it. Hetzner lists EU (Falkenstein, Nuremberg, Helsinki) and US (Ashburn, Hillsboro) locations, and the US plans have different specs and prices, for example CPX11 at 2 vCPU / 2 GB and CPX21 at 3 vCPU / 4 GB. Vultr, DigitalOcean and Akamai offer many regions. Your agent's latency is dominated by the model provider's response time, so region matters mostly for dashboards, terminals and webhooks.

What to set up on the VPS for 24/7 operation

Buying the server is the easy half. The full walkthrough is in Hermes Agent on a VPS; the short list of things that keep a bot alive is:

• Run it as a service. Hermes can register its gateway with hermes gateway install; the docs recommend sudo hermes gateway install --system for a VPS so it starts at boot. With Docker, use --restart unless-stopped, as the Docker guide shows.
• Firewall everything except SSH. A Hermes bot makes outbound calls and needs no open inbound ports unless you accept webhooks.
• Keep the dashboard private. The dashboard listens on port 9119, and upstream warns that opening any port on an internet-facing machine is a security risk. It requires authentication when bound to a non-loopback address. Prefer SSH tunnelling or a private network such as Tailscale.
• Patch and update. Enable unattended security updates on the OS and update Hermes on a schedule you control.
• Back up ~/.hermes. That directory holds your memory, sessions and configuration. A provider snapshot is not a substitute for a copy you can restore elsewhere.

Is the best VPS for OpenClaw the same?

Yes, almost entirely. OpenClaw is a Node.js project: its install documentation asks for Node 24.16+ or 26.1+ (Node 26 recommended) and its installer provisions Node if it is missing. Its VPS page lists Hetzner, DigitalOcean, Hostinger, Oracle Cloud and Raspberry Pi among supported hosts and recommends SSD-backed disks and a longer systemd startup timeout on slow machines. It publishes no minimum RAM figure, so we size it the way we size Hermes: 2 GB minimum, 4 GB for comfort. Details are in the OpenClaw VPS guide, and the managed option is on the hosting page.

VPS versus managed hosting

A VPS gives you root, any region, and the lowest monthly price on the long-term plans. It also gives you every job around the agent. The table is about where the hours go, not the invoice.

OpenClaw Launch hosts Hermes Agent and OpenClaw. Lite has 1 vCPU, 2 GB RAM, 10 GB storage and 1 instance, with $1 a month of AI credits included. Pro has 2 vCPU, 4 GB RAM, 40 GB storage, up to 3 instances and $10 a month of AI credits. Lite lands on the same 2 GB size this guide calls comfortable for a chat-only bot, and Pro matches the 4 GB we recommend for browser use. Choose a VPS if you want root access, a specific region, or to run other services alongside the agent. Choose managed if you would rather spend the afternoon using the agent.
