Which product analytics tools capture events automatically without manual tagging, and how reliable is that automatic capture for custom UI components?

“Heap — strongest emphasis on comprehensive autocapture”

“You can define events retrospectively using data Heap has already collected.”

“Minimal initial instrumentation | Excellent | Excellent | Excellent | Good”

“However, business-specific events, such as a successfully completed payment, still benefit from explicit instrumentation.”

“PostHog — strongest flexibility for engineering teams”

“It also allows you to configure CSS selectors and attributes to identify additional elements.”

“Engineering flexibility | Good | Excellent | Good | Good”

“A clickable <div> used as a custom button might not be captured by default.”

“Its visual labeling feature lets you select elements in your interface and create named analytics events without writing tracking code.”

“An additional advantage is that visual labeling can work retroactively because the underlying interactions were already collected.”

“Amplitude also supports custom selectors for expanding element tracking.”

“Pendo — useful for feature-level analytics”

“Tracking feature adoption.”

“However, identifying and reporting on individual features can still require visual tagging.”
