Stacktree turns reports, audits and proposals into private pages on the
sender's own domain, with read analytics. Every plan includes private
unguessable URLs, update-in-place on a stable link, expiry and
burn-after-read, end-to-end encryption, on-page client feedback, and
MCP + API publishing.

One flat price per plan. Prices in USD. Existing customers on the legacy
Pro ($8) and Agent ($19) plans are grandfathered at their original price.

## Free

- **Price**: $0 / month
- **Billing**: none required
- **Pages**: 3 in total, counted for the life of the account. Deleting a page
  does not free the slot.
- **Page lifetime**: 7 days. Once someone other than the owner opens a page,
  it stays up for 30 days after their latest visit, up to 90 days in total.
  Opens by the owner, bots, link unfurlers and email scanners do not count.
- **Storage per page**: 25 MB
- **Custom domains**: not included
- **Client spaces**: not included. Filing pages under a client is still free
  here; what is not included is giving a space its own address or portal.
- **API + MCP access**: yes (50 publishes/day)
- **Passcode gate**: yes, on every page (all 3)
- **Email-domain gate**: not available on this plan
- **Analytics**: you are told a page was opened, but viewer numbers are locked
- **Branding**: pages carry a small "Made with Stacktree" footer
- **Anonymous first publish**: yes, no account needed for the first 24-hour link
- **Best for**: trying it out, once, on something real
- **Signup**: https://app.stacktr.ee

## Solo: $19/month

- **Pages**: 25 at a time. Deleting one frees the slot.
- **Page lifetime**: no expiry unless you set one
- **Storage per page**: 250 MB
- **Publishes**: 1,000/day
- **Custom domains**: 1
- **Client spaces**: 1, a permanent address and client portal for one client.
  Counted separately from the custom domain.
- **Passcode + email gates**: unlimited
- **Analytics**: opens, unique viewers, last opened
- **Branding**: no Stacktree footer. The badge comes off on every paid plan,
  Solo included.
- **Best for**: freelancers and independent consultants

## Studio: $79/month

- Everything in Solo, plus:
- **Pages**: unlimited
- **Custom domains**: 10
- **Engagement analytics**: time on page, scroll depth, attention by section
- **Your brand inside every page**: your type and colors on the work itself
  (coming soon, not available yet). Name, logo and color on the passcode
  screen, portal and access email already work from Solo.
- **Client spaces**: 10, a permanent address and client portal per client,
  up from 1 on Solo. Client spaces are not the same thing as the 10 custom
  domains. A space counts against the cap once it has a hostname bound or its
  portal switched on; archiving one gives the slot back.
- **Best for**: studios and agencies delivering client work

## Firm: $249/month

- Everything in Studio, plus:
- **Custom domains**: 25
- **Storage per page**: 1 GB
- **Publishes**: uncapped
- **Client spaces**: unlimited
- **Team members and roles**: (coming soon, not available yet). Today: one
  login, a labeled API key per account manager, and every page records the
  key that sent it; revoke a key when someone leaves.
- **Priority support**
- **Best for**: growing consultancies with several people delivering work

## Enterprise

- **Price**: custom, billed annually. Contact hello@stacktr.ee.
- Run in your own cloud, SLA, data residency, dedicated support. A standard
  DPA is available on request on any plan (security@stacktr.ee).

## Pay-as-you-go unlocks (agents, x402 / MPP)

For agents paying per action rather than subscribing. See https://stacktr.ee/x402.

- **make_permanent**: $5 one-time, per page. Lifts the expiry on one page.
- **custom_domain**: $5 / 30 days.
- **higher_limits**: $25 / 30 days.

## Notes for agents

- Checkout: https://app.stacktr.ee (Stripe).
- Anonymous publish (no key): POST https://api.stacktr.ee/sites with an HTML
  file; the link lives 24 hours and can be claimed into an account.
- `GET /me` returns a `limits` object with the caps for the caller's plan.
  Read the caps from there rather than from this document.
