Comparison

Vellum vs Atticus

If you own a Mac and care most about the finished interior, Vellum wins on output and on the confidence of a live preview — for $249.99. If you are on Windows, or want drafting and formatting in one tool, Atticus is the answer at $147, and the quality gap is narrower than the price gap. Neither is wrong; the decision is usually made by which computer is on your desk.

This is the comparison most self-publishing authors actually run, and it is often presented as a close-run thing between feature lists. It is simpler than that. One of these does not run on Windows. If you are on a Mac the question is real, and comes down to whether you value the best possible output or the convenience of one tool that both writes and formats.

Vellum

$249.99 (print + ebook) / $199.99 (ebook only) · macOS only

Best for: Mac authors who format repeatedly and want the best output with no fuss

Strengths

  • Output quality is the benchmark — chapter openings and running heads look like a trade publisher set them.
  • Live preview across device sizes while you style, so nothing is a surprise at export.
  • One purchase covers unlimited books, which makes it cheap per title for a prolific author.

Where it stops

  • There is no Windows version, no browser version, and no announced plan for one.
  • The upfront price is the highest of the mainstream tools, paid before you know whether you like it.
  • Deliberately limited customisation — you work within its styles rather than designing your own.

Atticus

$147 one-time · Browser-based — Windows, macOS, Linux, Chromebook

Best for: Authors on any platform who want writing and formatting in one place

Strengths

  • Runs anywhere with a browser, which is the direct answer to Vellum's platform lock.
  • Combines drafting and formatting, so the manuscript never leaves the tool.
  • One payment covers unlimited books and includes future updates.

Where it stops

  • Output is very good but not consistently at Vellum's level on fine typographic detail.
  • Still a real application to learn, with a dashboard, settings and its own conventions.
  • Being browser-first, it is less comfortable if you work offline for long stretches.

Which one, for your situation

You are on Windows, Linux or a Chromebook

Atticus

Vellum will not run at all. There is no decision to make.

Mac, and the interior is what you care about

Vellum

Its defaults and chapter openings are still the benchmark, and the live preview means no surprises at export.

Mac, but you want to draft and format in one place

Atticus

It replaces two tools for less money. You give up some typographic polish for that.

You publish one book every few years

Neither, necessarily

A perpetual licence is poor value for a single title. A free tool or a per-book service will cost far less.

Is Vellum or Atticus better?

Vellum produces better-looking interiors and costs $249.99, but runs only on macOS. Atticus costs $147, runs in any browser on any platform, and combines writing with formatting. Windows authors have no choice — Vellum does not run. Mac authors should pick Vellum for output quality and Atticus for value and cross-device work.

Frequently asked questions

Is Atticus as good as Vellum?+

Close, and closer than the price difference suggests, but not identical. Vellum's advantages are in fine typographic detail and its live preview. In a plain novel interior most readers would not tell the two apart.

Can I move a book between them?+

Not as a project. Both import a manuscript, so the practical route is to export a clean DOCX and re-apply styling in the other tool. Expect to redo chapter-opening choices rather than carry them across.

Do either handle image-heavy books?+

Neither does this well. Both are built for text-led books. A cookbook, photo book or illustrated non-fiction title needs a page-layout application such as Affinity Publisher or InDesign.

Ceeryo is on this list — how impartial is it?+

Not entirely, and you should read it knowing that. What we can commit to is that every entry states where it beats us, that we do not name ourselves as the pick for jobs we do badly — image-led books and high-volume authors are both listed as reasons to choose something else — and that prices and platform facts are checked on the date shown at the top. Compare it against a source with nothing to sell before you spend money.
