Flat price, no account. Not a usage meter behind a login.
Sevalla is a capable full PaaS — but it bills by usage, hourly, behind an OAuth account. shiply.now hosts the app — with the database, functions, email, and domain it needs — in one call, on a flat price, with no account to start.
The short version: pick shiply.now when you want a predictable flat bill, email and a marketplace in the box, and an agent that ships in one call with no account. Pick Sevalla when you need the raw infrastructure breadth of a full PaaS — many container sizes, five database engines, object storage — and you are comfortable with a usage meter.
Usage-metered PaaS vs a flat line
This is the one thing to understand. Sevalla meters usage hourly across app containers, databases, and object storage, so the same app can cost very different amounts month to month — a busy month moves the number. That is the surprise-bill anxiety a flat model removes.
shiply.now removes the meter entirely. Free, $8, or $24 a month — that is the whole number, and the backend is included in it. Want to see what a metered bill does during a busy stretch versus a flat one? Try the hosting bill calculator and set your own numbers.

The number on the card is the number you pay
A metered PaaS adds up container hours, database size, and object storage — so a busy month becomes an expensive one. shiply.now is a flat monthly price with no meter, so the line stays flat no matter how the usage moves.
- Flat $0 / $8 / $24 per month, backend included
- No metered container, database, or storage overages
- A busy month changes your traffic, not your invoice
Ship in one call — not sign in, then operate an account
Sevalla's MCP is mature, but it is agent-as-ops on an existing OAuth account: you sign in first, then the agent operates your account. shiply.now is one call, no account — the agent POSTs once and the site is live, then one click claims it.
- No account to start — claim it later in one click
- Sevalla's agent runs on an OAuth account you sign into first
- Write-enabled MCP, 100+ tools — plus email + marketplace
Your agent gets full write access — secrets stay safe.
The agent keychain lets the AI store and use secrets — API keys, database credentials, tokens — without ever logging them to output. Combined with a write-enabled MCP and Workers Lite edge functions, your agent goes from zero to a live, production-grade app in one call.
Encrypted agent keychain
Store API keys and secrets per site. The agent retrieves and uses them; they never appear in tool output or logs.
Write-enabled MCP — 100+ tools
Publish sites, manage databases, attach domains, send email — one call, no account. Full docs at /docs.
Per-site email + marketplace
Inbox email, a marketplace to sell a finished site, and Studio for client handoff — the parts a raw PaaS leaves to you.
One call, live URL, no account
The agent POSTs once and gets back a real URL. No account needed to start — claim it in one click to keep it forever.
When Sevalla is the better choice
Sevalla is a strong, mature PaaS backed by Kinsta, and for a real set of projects it is the right call. Here is where it wins.
Reach for Sevalla when you need raw infrastructure breadth and scale — a wide range of container sizes up to $320 a month, five database engines, autoscale, and preview environments. For a team running heavy, long-lived services, that depth is real.
Its object-storage economics are strong too — $0.02 per GB with zero egress — and it carries the Kinsta pedigree with published case studies. At scale, on workloads dominated by storage or large containers, a usage meter can also be more efficient than a flat plan.
shiply.now is built for a different job: an agent that needs to ship an app — with a database, functions, and email — to a real URL right now, on a flat bill, with no account in the way, and a marketplace to hand it off. If that is the job, the rest of this page is for you.
shiply vs Sevalla — common questions
What is the difference between shiply.now and Sevalla?
Sevalla, by Kinsta, is a full PaaS on Google Kubernetes Engine and Cloudflare — app containers, five database engines, object storage, workers, and autoscale — billed by usage, hourly, behind an OAuth account. shiply.now hosts the app your agent built — a D1 or Neon Postgres database, Workers Lite edge functions and SSR, and per-site inbox email — in one call on a flat price, with no account to start. Sevalla goes broader on raw infrastructure; shiply.now trades the usage meter for a flat bill and adds email, a marketplace, and client-delivery handoff.
Is Sevalla usage-metered or flat-price?
Sevalla is usage-metered, billed hourly. App containers run roughly $5 to $320 a month depending on size, databases start at $5 plus $10 per 10GB, object storage is $0.02 per GB with zero egress, and static hosting is free. There are $50 of free credits to start. shiply.now has no usage meter at all: flat $0, $8, or $24 a month, and the backend is included in that price. That is the surprise-bill contrast — try the numbers on the hosting bill calculator below.
Does Sevalla include email or a marketplace?
No. Sevalla is strong on raw infrastructure but has no email, no marketplace, and no client-delivery tier. shiply.now includes per-site inbox email, a marketplace to sell or transfer a finished site, and Studio for client handoff. So while Sevalla goes deeper on containers and object storage, shiply.now covers the parts of shipping a real product that a pure PaaS leaves to you.
Can my agent publish to shiply.now without an account?
Yes. shiply.now needs no account to start — your agent POSTs once and the site is live at a real URL, then one click claims it. Sevalla has a mature hosted MCP, but it is agent-as-ops on an existing OAuth account: you sign in first, then the agent operates your account. shiply.now is one-call, no-account, agent-native by default, with a write-enabled MCP of 100+ tools spanning the database, functions, email, and domains.
Publish an app in one call.
Flat $0 / $8 / $24 per month. No usage meter, no account to start — your agent ships in a single request.
