• No licence cost at any user count.
• Full data control, which matters for defence, public sector and regulated work.
• Very stable and well understood.

• Extremely low friction — one click produces a report developers can act on.
• Genuinely useful free tier.
• Automatic repro steps and console capture cut triage dramatically.

• Dated interface that new team members find unpleasant.
• Plugin quality varies and upgrades frequently break them.
• You own hosting, backups, security patching and upgrades.

• Browser extension per reporter, so it does not work for anonymous end users.
• Chrome-centric.
• Not a tracker — you still need somewhere for the issue to live.

Organisations that must self-host and cannot spend on licences.

Product and engineering teams who want internal bug reports to arrive complete.
