KEEP IT

The value is the network, the data or the infrastructure. Keep paying.

Session replay and digital experience analytics: it reconstructs what a visitor saw and did, then lets you search across those sessions for rage clicks, dead clicks and errors.

Promptfree, for everyone, and the only version there is

Do not write a session recorder from scratch. Use rrweb, and be careful about what you capture.

STACK
- rrweb in the browser, your own endpoint, object storage for the event files

RECORDING
- Start rrweb with input masking on by default and an allow list of fields, never a deny list
- Block any element carrying a data-private attribute
- Cap a session at a fixed number of events and a fixed duration, then stop

UPLOAD
- Batch events and post on an interval and on page hide, with sendBeacon
- Compress before sending; these payloads are large

STORAGE
- One object per session in cheap object storage, one database row of metadata
- A retention job that actually deletes, and a documented number of days

PLAYBACK
- rrweb-player behind an authenticated page

WHAT YOU MUST DECIDE BEFORE ANY OF THIS
- Your lawful basis for recording, what consent you need, and how a person asks for their session to be deleted

Include the recorder config, the endpoint, the retention job and a README on the privacy defaults.

What you lose

A DOM-mutation recorder that survives single-page apps, canvas, iframes, shadow DOM and lazy-loaded fonts
Automatic privacy masking of inputs and text, which is a legal requirement rather than a nicety
Search across sessions by behaviour, not by user id
The storage and playback infrastructure for millions of session recordings

If you would rather not build

PostHog, which bundles replay and is self-hostable

Why this verdict

our own opinion · changed only by a person

22/100

Verdict no at 22. rrweb makes the recording feasible; the storage, the search and above all the privacy obligations are what you are really paying for.
