Hi HN, I’m Tom, the CTO and cofounder of Multiplayer.
We built this because we were tired of incomplete bug reports, hard-to-reproduce failures, and stale docs.
Where traditional recordings stop at the UI, we go deeper. This is all the data you wish was easy to get from your APM tool and screen recorder, all in one place.
Multiplayer records full-stack sessions (frontend + backend + request/response content and header + user steps) in three ways:
- On-demand
- Continuous (so no repro steps are needed)
- Remote (when users don’t notice or don’t report an issue)
You can install it via browser extension, widget, or SDK, and send backend data however you like (we’re backend-agnostic and OpenTelemetry-compatible).
Once a session recording is captured, you can:
- Annotate screenshots, API calls, and traces
- Share complete bug reports across dev, QA, and product
- Feed complete context into AI tools so they generate accurate fixes, tests, and features
Along the way we learned how tricky it is to capture context without slowing down apps, and how to make recordings useful instead of overwhelming.
We’d love feedback from the HN community:
- Would you use this more for debugging, testing, or feature work?
- Do session replays add clarity in your workflow?
Happy to answer questions and share what worked (and what didn’t) while building this.
