The ShipPage alternative that is private by default and does not expire.

ShipPage turns agent HTML into a public URL in one call, with a 14-day, 20-publish free tier. Stacktree starts from the opposite default: every link is unguessable, gates and encryption are one call away, free sites are permanent, and custom domains work today.

What is the best ShipPage alternative?

Stacktree, when the artifact should be private from the first byte and outlive two weeks. Both are agent-first HTML hosts with MCP servers on Cloudflare infrastructure. The split is the defaults: ShipPage publishes to a public URL with 14-day free retention; Stacktree publishes to an unguessable private URL, free sites are permanent, and deeper gates (password, email domain, end-to-end encryption) are built in.

Why people look for a ShipPage alternative

Public by default. ShipPage returns a public URL; privacy means adding a password afterward. If the artifact is an internal report, a client deliverable, or anything with data in it, you may want the opposite default: unreadable unless you hold the link.
14-day retention on free. ShipPage free pages expire after 14 days, with 20 publishes a month at 500KB each. Permanent retention sits in a Pro tier marked coming soon with pricing TBD. Links an agent shares into a thread or a doc should still resolve next quarter.
Custom domains are not live. They are listed under the future Pro tier. Stacktree maps custom domains today on Pro through Cloudflare for SaaS.

Where ShipPage genuinely wins

It deserves the credit: ShipPage's onboarding is about as frictionless as agent publishing gets. The first POST /v1/publish auto-registers the agent and returns an API key, no signup, no configuration. It ships an MCP server and an OpenClaw skill, works with Claude Code, Claude Desktop, and Cursor, and responds fast on Cloudflare infrastructure. If you want a throwaway public page from an agent in one call with zero ceremony, it does exactly that.

Where Stacktree differs

Private by default. Every URL is unguessable and acts as the credential. Add a password, a magic-link email-domain gate, or end-to-end encryption (the server stores only ciphertext) per site.
Permanent free sites. The free tier holds 5 active sites at 25MB each with no expiry. Anonymous no-account publishes last 24 hours.
Custom domains now. Live on Pro ($8/month), not a roadmap item.
Replace-in-place. update_site swaps content under the same URL, so the link shared yesterday shows today's version.
Agents can pay for themselves. A headless agent provisions a persistent identity for $1 over x402 (live on Base mainnet) and buys upgrades a-la-carte. No equivalent is documented on ShipPage.
OAuth and a dashboard. Hosted MCP clients connect over OAuth 2.1; humans manage sites, keys, and gates in a dashboard.

Who should pick which

Pick ShipPage for instant, zero-setup public pages from an agent, where two-week retention is fine and privacy is not the point.

Pick Stacktree when the artifact is private, needs to persist, needs your domain, or belongs to an autonomous agent that pays its own way. Same one-call publish, opposite defaults.

FAQ

Frequent questions

What is the best ShipPage alternative? +

Stacktree, when the page should be private the moment it exists and should not vanish in 14 days. ShipPage publishes agent HTML to a public URL with a free tier of 20 publishes a month and 14-day retention. Stacktree makes every URL unguessable by default, and free-tier sites do not expire.

Is ShipPage private? +

ShipPage pages get a public URL, with password protection available and search indexing as an opt-in. Stacktree inverts the default: every link is unguessable and acts as the credential, with optional password, a magic-link email-domain gate, and end-to-end encryption where the server stores only ciphertext.

How long do pages last on ShipPage vs Stacktree? +

ShipPage free pages last 14 days, capped at 20 publishes a month and 500KB per page; permanent retention is part of a Pro tier whose pricing is listed as TBD. Stacktree free-tier sites are permanent (5 active sites, 25MB each), and anonymous no-account publishes last 24 hours.

What does ShipPage do well? +

Zero-friction onboarding. The first API call auto-registers the agent and returns a key, with no signup, and it ships an MCP server plus an OpenClaw skill. It is a genuinely agent-first design. Stacktree matches the no-signup start with anonymous publishing and adds x402 pay-to-provision for autonomous identities.

Does either support custom domains? +

Stacktree custom domains are live today on Pro ($8/month) through Cloudflare for SaaS. On ShipPage, custom domains are listed for the Pro tier, which is marked coming soon with pricing TBD. If you need the artifact on your own domain now, that is a concrete difference.

Can an agent pay for hosting without a human on either? +

On Stacktree, yes: an agent with a funded wallet pays $1 over x402 (live on Base mainnet) to provision a persistent key, then buys upgrades a-la-carte. ShipPage auto-registers a free agent identity on first call but documents no payment rail for agents to buy persistence or upgrades.
