Optimal Workshop vs Dovetail
Feature checklists rarely decide anything. What decides it is the pricing metric, who has to write the tests, and which limitation you can live with.

Free tierWhat drives the bill
The metric that actually scales your invoice.
Annual plans reduce the effective monthly rate substantially; recruitment is separate.
Dovetail now publishes only the free tier and an Enterprise 'contact sales' option — the paid middle tiers carry no list price, so budget from a quote. Historically priced per contributor, with viewers cheaper or free.

Strengths
- The reference tool for card sorting and tree testing; the analysis visualisations are excellent.
- Tree testing validates navigation before any build effort is spent.
- Well-established methodology support and training material.
- Turns scattered research into a searchable organisational asset.
- Automatic transcription and AI-assisted theme detection save real analysis hours.
- Good at making findings visible to people who did not attend the sessions.
Limitations
- Narrow scope — it does not do usability testing of interfaces.
- Expensive per seat for occasional use.
- Interface is dated in places.
- It stores and analyses research; it does not recruit or run sessions.
- Value depends entirely on discipline — an untagged repository is a folder.
- Costs scale with the number of contributors.
Best for
Teams restructuring navigation, taxonomy or content on a large site.
Organisations running enough research that findings get lost.
All of these integrate with: Slack, Figma.
