Can Grok Bot build Hotjar?
the value is the network, the data, or the compliance. a bot can't conjure those.

Session replay looks like it should be a weekend project and it is one of the nastiest things on this list. You are serialising a live DOM, capturing every mutation, and replaying it faithfully across browsers you've never tested - while not capturing the password field, not capturing the credit card, not blowing up the user's bandwidth, and not tanking the page's performance budget. rrweb exists and is good, but the operational load is real and the privacy exposure of getting masking wrong is a genuinely bad day. Use PostHog's replay if you want this. Don't hand-roll it.
the prompt
Written for a bot that already has a browser, a terminal and your logins · paste it in whole.
Don't hand-roll session replay. Masking mistakes leak passwords and card numbers into a database, and that's a bad day you can avoid entirely. If you want replay, run something that already handles it: You have a computer and a browser. Stand up self-hosted PostHog with session replay enabled, and keep it running. - Official docker-compose, behind a stable URL with TLS. - Turn on session recording. Then, before it touches a real visitor, do the masking work properly: - Mask all input fields by default. Opt specific ones in, never out. - Add data-ph-no-capture to anything showing an email, a card, an address or a name. - Load my own site, fill in every form with fake sensitive data, then watch the recording back and confirm none of it is visible. Show me that recording. - Sample at 20% of sessions, not 100%. You do not need all of them and the storage is real. - Set retention to 30 days and enforce it. Ongoing: watch disk weekly and message me at 70%. Nightly backups off your machine. Re-run the masking test after any PostHog upgrade.
what you lose
- replay that works in browsers you never tested
- input masking that has been battle-tested against real leaks
- heatmap aggregation across thousands of sessions
- the storage bill being somebody else's problem
the numbers
Hotjar's pricing page now redirects to Contentsquare, which acquired it, and standalone pricing is no longer published. That alone is worth knowing before you build on it.
