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
Read the Docs
- Build configuration is finicky, and build failures on dependency changes are a common frustration
- Default themes are recognisable and dated, so sites look alike unless customised
- Private documentation requires a paid business plan
- Build times on large projects are slow enough to interrupt a review cycle
