Crypto VPS, AI agents over MCP, trading-bot hosting and paying in USDC/USDT — no KYC.
When you actually need 64 GB of RAM (and when 2 GB is enough)
Most slow servers aren't short of memory. Before you pay for 64 GB, find out whether you're waiting on RAM, on disk or on CPU: three commands that tell them apart, the workloads that genuinely need a big box, and the ones that run on 2 GB for years.
What AI agents actually need from infrastructure: 7 requirements, and where human-first hosting gets in the way
An agent that rents compute isn't a faster human. It can't solve a captcha, read an HTML error page or notice a runaway bill. Seven concrete requirements for infrastructure that software can use on its own, what each one prevents, and what is still unsolved.
VPS vs shared hosting vs dedicated vs cloud: an honest comparison
Four ways to rent a place for your code, and each one wins somewhere. Where shared hosting is simply the better deal, where a VPS earns its keep, when a whole physical server is worth it, where big cloud platforms shine, and the places a VPS is honestly worse.
Per-second billing, explained: why a 20-second sandbox costs $0.00055
“Billed per second” hides half a dozen decisions: what is counted, when the clock starts, minimums, rounding, and when the money actually leaves your balance. Here is our full formula with worked numbers, and the point where per-second stops being the cheaper option.
NAT or your own IPv4: what one forwarded port can and can't do
A NAT VPS gives you one personal SSH port and a normal outbound connection. Here's what runs happily on that, why port 443 and your own domain don't, the workarounds that are worth it and the ones that aren't, and how to move to an IPv4 plan without reinstalling.
Moving your VPS to a new provider without downtime
A migration checklist in the order that actually avoids downtime: lower the DNS TTL days before, build the new server next to the old one, sync twice, test it before anyone sees it, then switch. Plus the things that break most often, and when you can't avoid a short pause.
Container vs microVM isolation: 4 levels compared, from a subprocess to a full VM
A subprocess, a container, a microVM and a virtual machine all promise to contain code you don't trust. They stop very different things. Here is what each boundary actually blocks, how each one tends to fail, what it costs in start time, and a table for choosing.
Your IP is on a blocklist: how to check it in 5 minutes and what actually gets you delisted
Which blocklists matter, a three-line check you can run from any server, how to read the strange 127.0.0.x answers, why fixing the cause comes before the delisting form, and which listings you can safely ignore.
How to read VPS specs: vCPU, NVMe, 1 Gbit/s, “unmetered”
Two VPS plans with identical spec lines can behave very differently. What vCPU, NVMe, a 1 Gbit/s port and “unmetered” actually promise, which numbers are marketing, what to ask before you buy, and four commands to check a server in its first hour.
Firecracker microVMs in plain language: a real VM that boots in a fraction of a second
A microVM is a full virtual machine with its own kernel, stripped down until it starts almost as fast as a container. Here is what Firecracker removes to get there, how that differs from a container in practice, and what you give up in exchange.
Securing a self-hosted AI agent on a VPS
An agent with a shell and API keys is a new kind of risk. A separate user, systemd sandboxing, scoped keys, spending caps and prompt-injection hygiene.
IPv6-only VPS: what works and what breaks in 2026
Checked in September 2026: which services still have no IPv6 (GitHub, Discord, ghcr.io) and which work fine. How to test, workarounds, when you need IPv4.
