Change my answersStart over

1. Session Replay & Product Analytics

Because you said: “We can't reproduce the bugs users report”

Buyer’s guide
Microsoft ClarityBest fitFree

Free, unlimited session replay and heatmaps. Genuinely free, at any traffic volume.

Why this fits you

  • No cost and no sampling at any volume
  • Rage-click and dead-click detection surfaces real usability problems immediately.

Main limitation

  • Data goes to Microsoft, which is a real consideration for GDPR-sensitive deployments.
  • Filtering and segmentation are shallower than paid tools.
HotjarTalk to salesQuote only

Closed to new signups — Hotjar has been absorbed into Contentsquare.

Why this fits you

  • Non-technical teams adopt it without training, which is why it spread inside organisations.
  • Surveys and recordings together let you ask a user about the behaviour you just watched.

Main limitation

  • You cannot buy it: new accounts are closed and you are really evaluating Contentsquare.
  • Existing customers face a migration onto separately billed product lines, which can change the total.
AmplitudeFree tier

Behavioural product analytics with strong cohort and retention analysis.

Why this fits you

  • The deepest retention and cohort analysis in mainstream product analytics.
  • Good free tier for early-stage products.

Main limitation

  • Requires deliberate event instrumentation — nothing works without it.
  • Enterprise pricing rises steeply with tracked users.

2. Bug Tracking & Issue Management

Because you said: “We can't reproduce the bugs users report”

Buyer’s guide
JiraBest fitfrom $8Free tier

The default enterprise issue tracker, endlessly configurable for better and worse.

Why this fits you

  • Configurable enough to model almost any process, including regulated workflows.
  • The largest integration ecosystem in the category by a wide margin.

Main limitation

  • Configurability reliably degrades into slow, over-customised instances nobody wants to own.
  • Performance on large instances is a recurring complaint.
GitHub Issues & ProjectsFree tier

Issue tracking where the code already lives, free for most teams.

Why this fits you

  • Zero additional cost and zero additional integration to maintain.
  • Automatic linking between commits, pull requests and issues.

Main limitation

  • No native severity/priority model — you build it from labels.
  • Reporting is weak; there is no real analytics layer.
