Replayowl
Open source session replay, hosted or self-hosted
What is Replayowl?
Replayowl is open source session replay. It records what visitors do on your site and plays it back the way they saw it, including hover menus, Shadow DOM and CSS-in-JS. Sessions are merged across page loads, console errors and exceptions sit on the timeline next to the clicks that caused them, and you can search by your own user ID, page, device, errors or rage clicks. Text inputs are masked in the visitor's browser, so the original text never reaches the server. The recorder is 7.8 KB gzipped with no runtime dependencies. Use the hosted service with 1,000 free sessions a month, or self-host the same AGPL-3.0 code for free as one Cloudflare Worker or one Node process, with recordings in any S3-compatible bucket and session data in D1 or Postgres. It does replay only: no heatmaps or funnels.

Portfolio Company Hit $50M ARR In A Year With Zero Paywall Optimization — There Is Money On The Table
Jeff invested in a company that hit $50M ARR with a single subscription tier, no localization, and no paywall optimization at all. His estimate: handing the revenue keys to an experienced operator for a few sprints could double their revenue. Most fast-growing AI apps are fighting too many fires to refine monetization — which means there is enormous untapped value sitting in most subscription businesses.
if your product isn't like a solid 40 NPS I think marketing effort and dollars are kind of a waste of time cuz you're going to get a false negative people aren't going to want it you're not going to know if it's cuz your marketing sucks or your product sucks
Marketing spend is wasted until your product hits 40 NPS
Skylight launched its calendar product in 2018, gunned marketing in 2021-22, but the product was not ready and spend generated no traction. They nearly killed it entirely. The lesson: marketing before product-market fit produces false negatives that could kill a good idea prematurely. Hold marketing budget until NPS is comfortably above 40 so you are testing market demand, not product readiness.
There's a play for whatever you're stuck on.
