#  The Spacefast alternative for sending work to clients.

   Spacefast is a well-made private home for AI-built sites. Stacktree is built for the client who opens one.  Automattic's Spacefast keeps new spaces private, takes comments and counts visitors, and it is in research preview. Stacktree is open today, and it adds what client delivery needs: a passcode or email gate, a named link per person, who read it and for how long, sign-off, and a portal per client on your domain.

##  What is the best Spacefast alternative?

Stacktree, when the page is going to a client. Spacefast and Stacktree both keep AI-made pages private by default. Spacefast is a research preview aimed at sites and small apps; Stacktree is available now and built around the client: a passcode or email gate, named links, reading data per person, sign-off, and a client portal.

## What Spacefast is

Spacefast is Automattic’s service for publishing what AI agents make. You publish from a chat
      in Claude or ChatGPT, with `npx spacefast publish`, from a GitHub repo, or by dropping a
      folder on drop.website, and the result is a space at a live link. New spaces are private by default:
      a bare URL grants nothing, and you choose between inviting people, a share link anyone holding it
      can use, or going public. Comments pin to a spot on the page and can be replied to and resolved.
      Built-in analytics count views, visitors and top pages. It runs small apps too, with a database,
      sign-in, uploads and email built in.

As of 8 October 2026 it is a research preview with a waitlist. The announced plans are Free at $0
      (20 spaces and 20 custom domains, for personal, non-commercial projects), Go at $5 and Plus at $15
      per team per month.

## Where Spacefast is the better choice

  - Price and domains. Twenty custom domains on the free plan and unlimited on a $5 plan is far more than Stacktree gives at any price. If you host many sites, it is the cheaper home.
 - Apps, not only pages. A database, sign-in and uploads come built in. Stacktree hosts static pages and has no backend.
 - The Automattic ecosystem. If your agency already works through Automattic for Agencies, Spacefast arrives inside a program you know.

## Where Stacktree is the better choice

  - It is open today. No waitlist, and every paid plan is for commercial work. The first page is free, with no card.
 - A lock the client can open without an account. A passcode on every plan, and from Solo a gate that admits only verified addresses at the client’s company. Spacefast’s page documents invites, share links and public, not a passcode or an email-domain check.
 - Who read it, by name. Give each person their own link and every open comes back with their name: “Read by Maya Cole · 24 min over 8 visits”. Your own previews are left out. Spacefast’s analytics count visitors and pages, not people.
 - Sign-off. The client approves the page itself, and the record stays with it.
 - A portal per client. A [client space](/client-spaces) collects everything you have sent one client, newest first, behind one passcode at an address on your domain.
 - Where your client’s assistant can read it. Every page has a Markdown twin, and you can let a client review the page with their own AI, comments and all.

## For agencies weighing Automattic for Agencies

Automattic’s agency program shows Spacefast client spaces alongside partner pricing and
      referral earnings, and it is a sensible fit for agencies that already build on WordPress.com and
      want somewhere to put AI-built sites. The question to ask is what your client does with the page.
      If they browse a site, Spacefast fits. If they read a proposal, an audit or a monthly report and
      you need to know they read it before the call, that is the job Stacktree is built for, on any
      client’s domain, with no program to join.

## Pricing, side by side

Spacefast’s announced plans: Free $0 for non-commercial projects, Go $5 and Plus $15 per team
      per month. Stacktree: three free pages to try it with a real client, then Solo $19 (25 live pages,
      your own domain, a client space, passcodes and email gates), Studio $79 (unlimited pages, ten
      client spaces, reading time per person) and Firm $249. Spacefast will be cheaper for hosting.
      Stacktree charges for the client layer.
