We dropped FullStory/Mixpanel and built a tiny internal tool it saved us hours debugging. Should we turn it into a product?

A few months ago, our small SaaS team was using FullStory and Mixpanel to debug UX issues and understand what users were doing. But two things kept biting us:

• Session replay costs were growing fast as traffic increased even for basic usage.
• Mixpanel’s event-based pricing made it hard to predict billing, and it felt like overkill for the 3 reports we actually needed (retention, funnels, and error flows).

We also work with some EU clients, so data privacy and hosting were always a headache.

So... we built a tiny internal tool:

• Lightweight recorder script (captures sessions & events with <50ms load)
• 3 built-in reports: Top drop-off funnels, 7-day retention, error-prone flows
• Automatic PII masking (emails, credit cards, etc.)
• Hosted in EU or US (we let you pick)
• Predictable pricing: $49/mo for 1,000 sessions

It’s dead simple we set it up in a day, and it’s already saved us hours answering support tickets and debugging onboarding issues.

I’m thinking of turning this into a proper product — privacy-first, flat-priced session replay + core analytics for small teams.

Before I build more, I’d love to hear from others:

• Would your team pay for something like this?
• What do you actually use session replay or Mixpanel for?
• What’s missing or frustrating about tools like FullStory, Mixpanel, PostHog?

Curious to hear if this problem resonates or if we’re alone in feeling this pain.
