Why go for Cloud over building yourself?

~5× less bandwidth per session

Running the recorder, ingest, and storage as one integrated stack lets us aggressively tune the wire format end-to-end. A typical 5-minute recording weighs ~200 KB instead of ~1,000 KB. Fewer dropped events on flaky networks, cheaper egress, faster replays.

Hosted on the edge, close to your users worldwide

Recording ingest runs from a global edge network with hundreds of points of presence. Events arrive at the nearest region in milliseconds, which keeps recording reliable for users on slow or distant connections.

API-first. Use the open source you already know.

Cloud is built on the same rrweb packages everyone else uses. Pull in what you need. Every layer is open source, so you can adjust, fork, or extend any of it. Built to embed: ingest on your own domain, player unbranded.

import { record } from 'rrweb'
import rrwebPlayer from 'rrweb-player'
import { Replayer } from '@rrweb/replay'
import { snapshot } from 'rrweb-snapshot'
import type { eventWithTime } from '@rrweb/types'
// every layer is forkable, roll your own anytime

Every package is MIT-licensed open source. Swap plugins, change the serializer, or replace the player entirely.

Everything you'd otherwise be on the hook for, managed.

No engineers on call for the pipeline. No surprise compute spikes. No "we'll add backups next quarter."

Supports ongoing open source development

rrweb Cloud directly funds open source rrweb development. As rrweb Cloud is built by the team that maintains rrweb, using rrweb Cloud gives you access to its maintainers, and any issues you encounter with the library get fixed and contributed back for everyone's benefit.

Session replays, built for AI consumption

Every recording exports as a structured event stream that LLMs can read directly. Hand a session to your agent for triage, summarize it on demand, or stream the whole thing into a tool call.
