From bug detected to bug fixed, automatically
Multiplayer's debugging agent catches and fixes bugs automatically before end-users ever notice them.
For the bugs that do reach end-users they can report them directly via the Multiplayer extension or in-app widget. When they do, the report arrives with full-stack session context already attached, ready for the coding agent to generate a high-quality, merge-ready PR.
The perfect companion for coding agents
Multiplayer runs locally next to your favorite coding agent and captures full-stack session data (including the data observability tools miss!) only when something goes wrong.
Our debugging agent manages the whole process from bug identified to bug fixed: data gathering, intelligent triage and issue deduplication, coding agent prompting, PR creation and user notification.
Key benefits
Using Multiplayer results in what developers actually want from AI-assisted development:
Lower support volume
Multiplayer reduces the surface area for customer-reported bugs by fixing most of them proactively, and handles the ones that get through with a dramatically better signal than a traditional support ticket.
Catch quality issues you would otherwise miss
Unsampled, pre-correlated session data surfaces issues that tools like Sentry and APM never capture: transient bugs, session-specific failures, edge cases that fall below your error threshold. The bugs that often get sampled away.
Accelerated root cause analysis
Everything needed to understand the end-user bug is in one place, pre-correlated in a single timeline. This means less manual investigation time for you and fewer tokens burned on your coding agent grepping through unrelated data.
Reclaim feature development time
Inefficient (or manual!) debugging and PR slop wastes hours of developer time. Multiplayer keeps developers in feature development mode, with no context-switching into debugging, and no double-checking coding agent output because you're not sure it can be trusted.
Flexible installation for any support setup
Multiplayer adapts to your customer support workflow with four installation modes:
Terminal installation
One copy/paste in your terminal, and you’re done. Multiplayer is the perfect debugging companion that runs next to your coding agent so you can fix application bugs as they happen.
Browser Extension
Our extension supports teams on Chrome, Firefox, and Edge to start recording sessions instantly without code changes or deployments.
In-App Widget
Ideal for your SaaS products or internal tools: a customizable in-app reporting feature for developers, QA, or end-users to record full stack session recordings and capture their notes and feedback.
SDK Integration
Designed for teams who need to capture full stack sessions from command-line applications and backend services (Node.js, Go, Python, etc.).
