Capture what other tools miss with full stack session recordings
From complete frontend data to deep backend traces, logs, and full request/response content and headers for both internal services and external APIs.
Everything automatically correlated, no sampling, no blind spots
Session-based observability that captures 100% of your system’s behavior auto-correlated with user interactions. Not data scattered across five tools or sampled traces that miss critical edge cases.
Understand the most complex bugs without repro steps
Intermittent failures, race conditions, cascading microservice errors and more all captured automatically. See exactly what happened across your entire distributed system, from code to UI.
Automatically generate ready-to-approve PR fixes in minutes
Feed complete runtime context to your AI coding tools or use our autonomous AI agent. Either way, AI gets the actual data it needs to generate accurate fixes.
Fight vibe coded slop with complete runtime data
More AI-generated code means more bugs in production. Give your AI tools the exact session data, full payloads, and correlated traces they need to fix what they break, instead of guessing from incomplete logs.

On-demand recording
Capture full stack session recordings on demand with a browser extension, in-app widget, or SDK. Developers, QA, product, support, and even external partners can instantly record and share issues, explore system behavior, and collaborate with sketches and annotations to fix bugs or design new features.
Continuous recording
Record all sessions automatically in the background, so reproducing issues is never required. Multiplayer saves recordings the moment bugs or anomalies occur making it effortless to capture elusive, hard-to-reproduce problems.
Conditional recording
Silently capture user sessions without any manual steps or bug reports. Multiplayer detects and records issues even when users don't notice or don't report them, giving your team complete context to resolve problems faster and avoid unclear, incomplete tickets.
From bug to fix. From idea to feature. Power all your AI workflows with full stack, annotated session replays.
AI-ready annotated recordings
Turn session recordings into actionable development plans to share with your team or your AI coding assistant. Select traces, API calls, or user interactions, and annotate directly on screenshots: whether it's sketching over a button, specifying new API routes, or listing the reqs of new features. Every bug fix or feature request comes with precise, context-rich instructions.
MCP-ready full stack context
Feed your copilots and AI IDEs the complete system context they need: user actions, traces, logs, requests, responses, header data, plus team annotations. No missing data, no guesswork. Your AI tools can generate accurate fixes, tests, and features with minimal prompting.

"Supporting our internal apps used to be a mess: incomplete tickets, endless back-and-forth, even jumping on live calls just to understand what went wrong. With Multiplayer, we finally get the full picture up front, so issues actually move forward instead of getting stalled in support."
"Before Multiplayer, reporting bugs was frustrating: I'd spend time writing out repro steps, only to hear back 'works on my machine.' Now I just hit record, share the session replay, and the devs have everything they need to fix it right away."
"Our customers used to send us incomplete notes like 'it just doesn't work.' Now they can record a session and I can forward it to engineering with zero context needed—my issue gets resolved right away."
"I don’t get paged anymore to interpret why tests failed. The team opens the replay, sees the flow, and knows immediately if it’s a code issue or a flaky test. That alone has freed up 20% of my time."
"We run hundreds of microservices. Debugging cross-service issues used to feel impossible without building custom dashboards. Multiplayer’s correlation makes the system finally understandable for humans."
"When I spot something in a session recording, I can just sketch or leave notes right there and feed it straight into my AI copilot. I don’t have to stop what I’m doing to piece together context from different places first, before working on a fix or new feature."
Purpose-built for all engineering workflows
Feed the right data to your AI IDE
Build new features with confidence
Capture every issue, from customer apps to internal tools
Understand why your tests are failing
