Two kinds of visibility every software team needs: whether credentials have leaked, and where users silently struggle.
Lunar
A free, open breach-search platform by Webz.io that monitors compromised employee credentials, stolen session cookies, and infostealer logs across the open, deep, and dark web.
Why it made the list: Basic breach visibility is genuinely free for any organization; the enterprise tier adds instant alerts, integrations (SIEM/ticketing), and automation.
Pricing: Free tier for breach visibility; enterprise tier adds alerting, integrations, and automation (quoted).
Watch out for: The free tier shows exposure but doesn't push alerts — you have to check. Full automation is enterprise-tier.
Contentsquare
A UX analytics platform with session replay, heatmaps, and AI-surfaced friction insights — showing why users drop off, not just that they did.
Why it made the list: Goes past pageview analytics into behavior: rage clicks, hesitation, broken interactions.
Pricing: Free plan exists for smaller sites; Growth starts around $40/mo; Pro/Enterprise custom-quoted.
Watch out for: Serious value needs traffic volume — on a low-traffic site the AI insights have little to learn from.
Which one first?
Every tool above earns its slot for a specific job — start with the one whose "why it made the list" matches the problem currently costing you the most hours, run its free tier or trial against one real task, and only then commit. Stacking all of them at once is how tool budgets die.
