Appinio vs crul: at a glance
What is Appinio?
Appinio is layering AI across the research workflow, from survey draft to reusable insight.
Appinio is steadily wrapping its survey platform in AI: importing drafts from any document format, generating sentiment and multi-question insights on results, and turning past studies into a queryable knowledge base. The non-AI work is polish — dark mode, white-labeled sharing, flexible KPI displays, richer significance testing — aimed at making the tool presentable to stakeholders. The shape is a research tool trying to compress the distance between fielding a survey and acting on it.
What is crul?
crul took mocking back from webmockr and made it a property of the client itself
crul is the R6-based HTTP client underneath much of rOpenSci's package stack, covering synchronous requests, three flavours of async, pagination and retries. Its 1.6.0 release in July 2025 changed where test mocking lives: each client — HttpClient, Async, AsyncVaried — now takes a mocking parameter at initialisation or per method, and the standalone mock() function is deprecated. Mocking used to be something webmockr switched on from outside; it is now a setting on the client.

◆ Current state
Appinio is steadily wrapping its survey platform in AI: importing drafts from any document format, generating sentiment and multi-question insights on results, and turning past studies into a queryable knowledge base. The non-AI work is polish — dark mode, white-labeled sharing, flexible KPI displays, richer significance testing — aimed at making the tool presentable to stakeholders. The shape is a research tool trying to compress the distance between fielding a survey and acting on it.
◆ Where it's heading
Direction is toward AI handling the tedious ends of research: setup and synthesis. The questionnaire importer removes data entry at the front; sentiment analysis and the cross-survey knowledge base remove manual reading at the back. If the knowledge base graduates from beta, Appinio shifts from a per-study tool toward an institutional research memory.
◆ Prediction
Expect the beta knowledge base to reach general availability and connect to the AI insights engine, so users query across all historical surveys rather than analyzing one at a time.

crul took mocking back from webmockr and made it a property of the client itself
◆ Current state
crul is the R6-based HTTP client underneath much of rOpenSci's package stack, covering synchronous requests, three flavours of async, pagination and retries. Its 1.6.0 release in July 2025 changed where test mocking lives: each client — HttpClient, Async, AsyncVaried — now takes a mocking parameter at initialisation or per method, and the standalone mock() function is deprecated. Mocking used to be something webmockr switched on from outside; it is now a setting on the client.
◆ Where it's heading
The async surface has been the growth area for years — retries reached Async, AsyncVaried, AsyncQueue and HttpRequest in 1.4, AsyncQueue gained the response accessors in 1.2, and 1.5.0 wired async requests up to webmockr. The 1.6.0 change reverses that direction of dependency, and it landed within a minute of webmockr's own release severing its tie to vcr. Read together, the rOpenSci HTTP stack is being deliberately untangled so each package can be used without the others.
◆ Prediction
With mock() deprecated rather than removed, the next major release is the likely point of deletion. Expect the remaining work to follow the same decoupling theme rather than adding request features.
