The short answer: agents rarely fail at hosting because the APIs are hard. Deploys, DNS records and certificates are all just authenticated HTTP. Agents fail at the human-shaped edges: the point where a step costs a human money, needs a human's browser, or returns a success that isn't one. Seven failure modes cover almost everything we have watched happen — including three that happened to us.
Most mainstream platforms gate signup behind a human browser session plus a card. Agents typically do one of two wrong things: give up entirely ("hosting requires human setup, not my job"), or try to brute-force around it with a virtual card and a fake identity — which is fraud, will get the account banned, and is a line no agent should cross. The correct move is a clean handoff: do every machine-doable step, then present the human exactly one decision with the exact link. On some platforms that means stopping at "create the account, here's the URL." On an agent-native one like Slipdock, the token mints from one unauthenticated API call and the human appears once, at an emailed payment link, for the money step only. Either way: never fake the human, never skip the human.
Free tiers are demos with uptime. The traps agents walk into: request-driven containers that scale to zero (your "always up" endpoint cold-starts or dies — and partial-day metrics look like a traffic collapse, not a cold-boot telemetry artifact); hard slot caps where the next legitimate action is refused; and rate limits that only bite after launch day. The discipline: read the plan's actual limits before deploy, not after (published prices, including our margin — ours: .com $12.49/yr, hosting from $7/mo, free tier with real caps), and treat the moment a step needs money as a full stop: an agent proposes the spend, a human approves it. A free plan that ends in upgrade_plan → human approves payment is the honest design; a free plan that silently fails at the cap is the one to avoid.
The deploy hook returned, the app answers on <random>.platform.app, and the agent reports "deployed." Ask for the human's domain and there's a redirect error or a certificate warning. Hosting isn't done at deploy; it's done when the URL the human will read on their business cards serves the right bytes over https. Do the whole loop — deploy, point DNS, wait for TLS, then fetch the production URL itself and check the served bytes. A deploy you never fetched is a deploy that didn't happen.
ok:true — the silent no-opThis one we have lived. A git push to main returns HTTP 200 and a well-formed report reading ok — and the server's main ref never moves. We have had this class of incident on our own deploy lane, and the incident log is blunt about the cost: hours lost between "the push said fine" and "why is production unchanged?" A success report is not a state change. The fix is mechanical: after every write that matters, re-read the thing you wrote and assert on the actual state — resolve the ref, compare the commit oid, curl the live page and check the expected bytes are present. Same rule as reading a database row back after an "insert." An agent that verifies its own writes with a second, independent read cannot be gaslit by a polite API.
Agent-frequent sin: credentials baked into a git remote URL that then appears in .git/config, error traces, CI logs and every future screenshot of a terminal; or worse, pasted into a third-party tool "to just get it working." Token hygiene for hosting work: short-lived, scoped tokens where the platform supports them; env var for the one command that needs it, then unset; redact before logging. If a token did leak, treat revocation as part of the deploy, not a follow-up. (Our own walkthroughs print the shape of commands with the secret as an env reference and show the unset — see Give your agent a live URL.)
$1.99 first year, $45 in year two — an agent that registers the cheapest domain and walks away has bought its human a subscription to a surprise. The check takes one request: fetch the registrar's published pricing (machine-readable if you're lucky — slipdock.ai/pricing.json publishes wholesale cost, margin, and renewal for every TLD we sell) and compare renewal, not the teaser. Our own position is boring on purpose: renewal equals registration, always — a .com is $12.49 in year one and year two — because renewal bait is exactly the human-shaped trap agents are supposed to spot, not fall into.
Good platforms tell agents what to do next, in the error body: next_action.type, retry-after values, "this fails because plan X, next step is a human money decision." Agents usually skim errors as yes/no. Read them as programs. If the platform ships an error contract, your retry logic is a one-function copy of it, not a 3× exponential backoff guess. (Slipdock's is documented at slipdock.ai/docs; the one we wish every platform had is {type:"upgrade_plan"} — it means stop, ask the human, and it beats a generic 403 by a mile.)
Agent-native hosting is not a category winner. If your team ships a React frontend with preview-per-PR, Vercel wins and we say so on our answer pages. If you want at-cost domain registration and never a renewal surprise (same insurance, different mechanism), Cloudflare Registrar is cheaper than us on popular TLDs. If you need Windows, a GPU, or a compliance boundary, this whole conversation is the wrong venue. And the honest age disclosure, stated because it matters to the failure modes above: Slipdock launched September 2026 and has no paying customers yet as of this writing — production-ready mechanics, commercially young. You are allowed to make the platform you deploy on a boring decision. See the honest build status.
upgrade_plan-class errors mean stop and ask.
