Full stack session recordings: end-to-end visibility in a single click
Multiplayer gives your team full stack session recordings so you have all the context you need to fix bugs, build features, and supercharge your AI tools. This is all the data you wish was easy to get from your APM tool and screen recorder - all in one place.
What is a full stack session recording?
A full stack session recording captures the entire path of system behavior (from the frontend screen to the backend services) automatically correlated, enriched, and AI-ready.
In a single replay, you see:
- The screens and actions a user took
- The backend traces and logs triggered by those actions
- The request/response content and headers exchanged between all your components
- Metadata like device, environment, browser, etc.
- User feedback, plus annotations, sketches, and comments from the engineering team
Instead of stitching together screenshots, console logs, APM traces, and bug tickets, a full stack session recording shows you the whole story, end to end.
How is it different from other tools?
Most tools that promise “visibility” into your system fall into one of three buckets:
- Frontend session recorders (e.g. FullStory, LogRocket, Jam): Great at showing what the user saw and clicked, but they stop at the browser. Some bolt on backend visibility via integrations, which means extra cost, more tools to manage, and sampled data.
- Error monitoring tools (e.g. Sentry): Useful for flagging what broke, but not built for the full debugging cycle (root cause analysis, testing, validating fixes, and developing new features).
- APM/observability platforms (e.g. Datadog, New Relic): Perfect for monitoring system health and long-term trends, but not for surgical, step-by-step debugging through a session replay.
Multiplayer is different. It gives developers the entire story in one session, so you don’t waste hours context-switching between tools, grepping through logs, or chasing repro steps.
With Multiplayer you get:
- Full stack out of the box, no sampling
- Backend agnostic design: use any observability stack, avoid vendor lock-in
- Actionable recordings: test fixes, build features, align with your team
- Versatility: multiple install options and recording modes to fit your workflow
Use cases across the engineering lifecycle
With Multiplayer, one tool powers many workflows out of the box. From debugging and testing to support, development, and documentation.
- Debugging: Capture everything from intermittent bugs to hard-to-reproduce issues in distributed systems. See the full path frontend-to-backend and pinpoint the root cause immediately.
- QA & testing: Understand why tests fail, auto-generate runnable scripts from recordings, and use notebooks to chain API requests and code blocks into realistic multi-step workflows. Simulate real data flows across services just like in production.
- Software development: Annotate recordings with sketches, notes, and requirements. Highlight API calls, traces, or interactions and turn them into actionable development plans which you can share with your team or use as precise AI prompts.
- Documentation: Automatically capture your system as it evolves: architecture, components, APIs, dependencies, and environments. Say goodbye to static diagrams and outdated wikis.
What makes full stack session recordings powerful?
Where traditional replays stop at the UI, full stack session recordings go deeper—capturing the entire stack, automatically. Multiplayer makes that power practical with:
- Flexible recording modes: on-demand, continuous, or remote
- Multiple install options: browser extension, in-app widget, or SDK
- Full stack data by default: frontend + backend, auto-correlated, no sampling
- Rich annotations: sketches, notes, and comments
- AI-native design: an MCP server to feed copilots and agents complete context
- Living knowledge: notebooks and system dashboards that evolve with your code
With Multiplayer, a single session replay isn’t just a playback of what happened: it’s a complete, actionable view of your system that accelerates debugging, validates fixes, and fuels development.
