The short version

  • Only ReadMe has a free tier, so it costs nothing to try first.
  • Each has a real cost: MadCap Flare flare is now subscription-only at $3,150 per author per year; a buyer who previously owned a perpetual licence faces an ongoing cost that did not exist under the old purchase model; ReadMe pricing is per project, so an organisation with several distinct APIs multiplies the monthly bill rather than adding seats, and the sensible workaround, merging unrelated APIs into one documentation project, distorts the information architecture to fit the invoice.
  • They diverge on capability: MadCap Flare covers Single-source publishing, ReadMe covers OpenAPI reference.
  • Prices and features above were last checked on 1 September 2026.

What people use each for

  • Cutting support load by showing an integrating developer their own recent failing requests next to the endpoint descriptionnot MadCap Flare
  • Keeping documentation versions aligned with API versions so customers on an older release read the matching referencenot MadCap Flare

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

MadCap Flare

  • Flare is now subscription-only at $3,150 per author per year; a buyer who previously owned a perpetual licence faces an ongoing cost that did not exist under the old purchase model
  • A 12-month commitment is required on Flare Online, so a team cannot trial the cloud tier month to month before committing budget
  • Pricing above the Desktop base tier is entirely quote-based for Online plans, so team and business-tier costs are not comparable across vendors without a sales call
  • The authoring model, while less rigid than a full CCMS, still requires writers to learn topic-based structuring, conditional tags and variables, which is a real ramp for staff used to Word or a wiki
  • Storage is capped per tier with paid add-ons in 10 GB increments, so a documentation set with heavy image or video assets can incur additional cost beyond the headline price
  • Windows-only desktop authoring limits teams that standardise on macOS or Linux to the browser-based Flare Online tier, which may not have full feature parity with desktop

ReadMe

  • Pricing is per project, so an organisation with several distinct APIs multiplies the monthly bill rather than adding seats, and the sensible workaround, merging unrelated APIs into one documentation project, distorts the information architecture to fit the invoice.
  • The metrics and personalisation features require your API to stream request logs to ReadMe, which means production request metadata leaves your infrastructure and needs a scrubbing layer plus a security review before anything is switched on.
  • Single sign-on and private documentation sit on the higher tier, so a company that only needs to gate partner documentation behind SAML pays a large step up for one control.
  • The platform is built for describing REST APIs, and long-form product manuals, internal knowledge bases or non-OpenAPI protocols fit it badly, so most customers end up running a second documentation tool alongside it.
  • Theming is bounded by ReadMe templates and limited custom CSS, so a documentation site that must match a strongly designed marketing site will not get there without compromise.
  • Content uses ReadMe-specific Markdown extensions and platform features, so migrating away is an export plus a rewrite rather than moving a folder of Markdown files.

Answered from the vendors’ own pages

MadCap Flare: Is there still a perpetual licence option?

No, MadCap Flare is sold on an annual subscription basis; the previous perpetual licence model is not offered on current pricing.

ReadMe: Is ReadMe priced per user?

No. It is priced per project, meaning per documented API. Team size does not change the bill, and a second API generally does.

MadCap Flare: What is the entry price?

Flare Desktop is $3,150 per author per year; Flare Online plans are quote-only.

ReadMe: Do I have to send my API logs to ReadMe?

Only for metrics and personalised documentation. The reference, guides and playground work without it, but the features that most distinguish the product are the ones that need the log stream.

MadCap Flare: Is there a minimum commitment?

Flare Online requires a 12-month commitment; Flare Desktop is billed annually.

ReadMe: Can I keep documentation in Git?

Yes. The rdme command line tool synchronises Markdown and OpenAPI files from a repository, so documentation can ship in the same pull request as the code.

ReadMe: Can I self-host it?

No. ReadMe is a hosted product only, so buyers with a hard on-premises requirement need a different platform.
