Stacklumen Base is bought on the same Stacklumen account as your plan, for every workspace, on the same invoice. It is separate from Stacklumen's Agency plan ($99.99 a month), which covers the Hub and Terminal and does not include it. For the suite-wide view, see Stacklumen pricing.

A run is one audit. Instant tools are free.

An audit is one of the 9 tools that take a URL and fetch the site; Advanced Audit runs each grader as its own run. The 5 instant tools run in your browser and never count.

  • Stacklumen Base Free. 10 audit runs a month in each workspace.
  • Stacklumen Base. 1,000 audit runs a month in each workspace.

Audit

  • Runs spent5

Each grader is a full run and counts toward your allowance. The scores in this drawing are illustrative.

Advanced Audit: one URL through every grader at once, each saved as its own run. The scores drawn here are illustrative, not a real result. The drawing is the Advanced Audit tool. A URL is entered and Audit site pressed; the 5 graders — SEO + AEO, Accessibility, Security Headers, Schema, Maintainability — and optionally Speed run three at a time, each card filling with its score, and an overall mean appears above them.

Free beside paid. What each one reaches in Stacklumen Base.

Both open every screen, and agents connect to both. What Stacklumen Base changes is which components you copy into Terminal, how many audits you run and how many designs you keep.

Common questions. Plainly answered.

Plans

  • Does Stacklumen Base have its own plan?

    Yes. Every Stacklumen account has Stacklumen Base Free, and Stacklumen Base is $29.99 a month ($24.99 a month billed yearly, $299.90 a year) for every component, 1,000 audit runs a month in each workspace and unlimited designs. It is bought once for the whole agency, on any Stacklumen plan, Free included.

  • Is it part of Stacklumen's Agency plan?

    No. The Agency plan ($99.99 a month) covers the Hub and Terminal and does not include Stacklumen Base, and neither does its 14-day trial. Stacklumen Base is bought beside it, or on its own, on the same Stacklumen account and invoice.

  • Where do we buy it?

    In Billing on Stacklumen, which opens on the Stacklumen Base line. Stacklumen Base shows what the agency holds under Workspace, Billing, and links there; it sells nothing itself. Prices are in US dollars and exclude tax.

  • How does yearly billing work?

    Stacklumen Base bills yearly for the price of 10 months: 2 months free, $299.90 a year.

  • Who takes a seat?

    Seats are your Stacklumen plan's, counted once across the agency; Stacklumen Base adds no seat limit of its own. Viewers and client guests never take a seat.

  • What happens if we stop paying for Stacklumen Base?

    Nothing is deleted. Components already copied or placed stay where they are, and every design stays in the library. The agency goes back to the free set and 10 audit runs a month, and a workspace with 10 or more designs adds a new one only once it is below that.

The library

  • What does Stacklumen Base Free include in the library?

    Every component, browsed and previewed. Copy for Terminal and the Stacklumen Base panel take the free set: 24 components chosen to build a whole page, from the bar and hero to the sections, a form and the footer. Stacklumen Base takes every component, and a premium component opens once the workspace buys it.

  • Are templates part of a plan?

    No, and Stacklumen Base does not include them. Each template is licensed to one workspace from the Marketplace, on any plan: Stacklumen's own are $59 to $149, once. Creators' items are priced from $1 to $149, and a creator keeps 80% of each sale.

  • What counts as a run?

    An audit: one of the 9 tools that take a URL and fetch the site. The 5 instant tools run in your browser and never count.

  • Is the designer limited?

    Drawing never is. Stacklumen Base Free keeps 10 designs in each workspace's design library, and archived designs do not count. Stacklumen Base keeps as many as you like.

  • Can an agent use Stacklumen Base?

    Yes, over MCP, on every plan, Stacklumen Base Free included. An agent takes what the workspace may take: the free set without Stacklumen Base, every component with it. Agents run on your own AI plan, so nothing is billed for model use.

The alpha

  • Is Stacklumen Base free right now?

    Stacklumen Base Free is, on every Stacklumen account. Stacklumen Base is $29.99 a month, charged on the agency's Stacklumen account from the day it is bought.

  • What still applies during the alpha?

    Who you are, not what you pay. Client guests are not given the library or the tools, rate limits stay on, and templates are still licensed one at a time.

  • Is there a trial?

    Not of Stacklumen Base: Stacklumen Base Free has no end, and Stacklumen Base is charged from the day it is bought. Stacklumen's one 14-day Agency trial, with no card, covers the Hub and Terminal and does not include Stacklumen Base.

Start on Stacklumen Base Free. Add Stacklumen Base when you need every component.
