What a small VPS can and cannot run for self-hosted agents
Updated 2026-11-08 · Decision boundaries, not a benchmark.
No performance claims here. We have not run benchmark suites, uptime measurements, or model-inference tests. Nothing on this page says a specific plan is fast enough. The point is to name the questions worth asking before you buy.
Running an agent is not one workload. A gateway that forwards messages, a scheduler that fires webhooks, and a local model server have completely different resource profiles. Confusing them is the most common reason a "cheap" server turns out to be the wrong purchase.
Usually a reasonable fit
| Workload | Why it tends to fit | Check first |
|---|---|---|
| Personal proxy or tunnel | Network-bound, light on CPU and RAM | Dedicated IPv4, acceptable-use policy, routing and latency |
| Scheduled jobs and webhooks | Idle most of the time | Disk space for logs, whether background processes are allowed |
| Agent gateway / message router | Orchestration is mostly I/O | Persistent storage, restart behaviour, secret handling |
| Small self-hosted automation | Single-user, low concurrency | RAM headroom for the runtime and database |
Usually the wrong tool
| Workload | Why |
|---|---|
| Local LLM inference | Memory and often GPU-bound; a small CPU-only VPS is the wrong class of machine. Our matcher rejects it explicitly. |
| Production service with paying users | A single instance is a single point of failure. Requires backups, restore drills and failover — see the rejection reasons. |
| Managed application with no sysadmin | Self-managed means you own OS updates, security and recovery. See the managed-app rejection. |
| High-throughput scraping or sustained CPU work | Fair-use and CPU limits apply; check the provider's terms before buying. |
The pre-purchase checklist
- Is a dedicated IPv4 included? Some low-cost plans are NAT-only or charge extra.
- What is the renewal price? An introductory rate is not the 12-month cost — see how to normalize quotes.
- Are backups included, and can you restore them yourself?
- Does the acceptable-use policy permit your workload? Proxies, mail sending and automated requests differ by provider.
- Can you rebuild elsewhere quickly? The cheapest plan is one you can leave.
- Which fields are still unknown? Our catalog lists them explicitly rather than estimating.
For buyer agents
If you are an automated buyer, do not infer specifications from this page. Fetch the catalog, read unverified_fields, and use the integration notes. The matcher returns explanations, never a score.
