AI-Powered Debugging for Distributed Systems

Get started for free

Loved by engineering teams from startups to enterprises

Debug smarter, not harder.

Sick of grepping through log files, hot-potato hand offs, and relying on multiple tools?
  • Capture and share deep session replays that combine frontend screens with backend traces, logs, and metrics
  • Use interactive notebooks to reproduce issues, test hypotheses, and hand off knowledge cleanly across teams and time zones
  • Auto-document your architecture in real-time and gain full insight into your running system

One Platform. System-Wide Clarity.

Multiplayer gives your team everything they need to find, reproduce, and fix bugs—fast.
AUTO-GENERATE RUNNABLE TEST SCRIPTS

Effortless bug reproductions and fixes

Notebooks make it easy to understand issues, reproduce bugs, validate fixes, and prevent regressions.

With API calls, code logic, graphs, and real-world data all in a single, collaborative, and interactive place, you can easily generate a test script from a debugging session, design a new integration workflow, or validate your fix.Explore Notebooks

“Multiplayer saves my team hours every week. With frontend and backend context, repro steps, and user notes all in one place, we go from bug report to fix without playing detective across five tools.”

Marcus L. avatarMarcus L.QA Team Lead, E-commerce Platform

“We used to have a quarterly meeting where we’d all fly in, unfurl a giant poster and add post-it notes with our bits of the software architecture. It was obsolete the moment someone shipped a new feature. Now, we have real-time visibility, full accountability, and an easier way to collaborate.”

“We replaced multiple tools with Platform Notebooks—it’s the only place where API testing, debugging, and documentation happen together, without jumping between different apps.”

Aurelia D. avatarAurelia D.Customer Success Engineer, MarTech Vendor

“This is the fastest way I’ve ever seen to answer the question ‘What’s in our backend’?”

Kelsey M. avatarKelsey M.Engineering Manager, EdTech Platform

“We had no idea how messy our system had become until we visualized it in Multiplayer. That clarity helped us kick off the architecture modernization we’d been avoiding for years.”

Luis G. avatarLuis G.Principal Engineer, FinTech Company

“Onboarding new engineers used to take weeks. Now they get real-time architecture diagrams, API workflows, and system context on day one. Time-to-PR is now just a few days”
