Build Features Faster with Full-Stack Visibility

Understand your system end-to-end, collaborate with rich annotations, and turn real session data into AI-ready feature plans.

Go from Idea to Implementation, Faster

The Challenges of Feature Development

Traditional development workflows leave teams guessing about system behavior:

  • Disconnected frontend and backend understanding
  • Unclear cross-service dependencies and interactions
  • Difficult to anticipate downstream impacts of changes
  • Time-consuming context gathering for AI coding assistants
  • Inefficient team collaboration and alignment

How Multiplayer Accelerates Feature Development

Multiplayer helps developers move from idea to implementation faster by providing a complete, contextual view of how their system behaves. Every recording becomes a shared source of truth for designing, building, and reviewing new features.

Complete System Visibility

Understand how a feature interacts across services with full-stack session recordings that correlate frontend actions, backend traces, logs, request/response content and headers in one unified view.

Context-Rich Annotations

Turn session data into actionable plans. Sketch new UI ideas, document requirements, or comment directly on APIs, traces, spans, and user interactions right inside the recording.

AI-Ready Context

Feed your annotated session data into any AI coding assistant to generate accurate suggestions, tests, or feature implementations without endless prompting.

Team Collaboration

Share annotated recordings with your team for instant alignment. No more context lost in tickets or threads: everyone works from the same live, visual record.

Feature Development Workflow

Before you build, you need to understand what you’re changing and how your system actually behaves. Full-stack session recordings make that discovery process visual, contextual, and collaborative.

With Multiplayer, developers can:

  • Record on-demand or continuous sessions to see the complete flow of a feature in action. From the user’s screen to the backend traces, logs, etc.
  • Explore the system visually using automatically generated system maps to trace how data moves and where dependencies live.
  • Experiment and validate APIs in interactive notebooks that let you test endpoints, tweak payloads, and confirm integrations before writing new code.
  • Annotate session recordings with sketches, notes, or requirements directly on UI elements, user interactions, API routes, and spans.
  • Document implementation plans right inside the recording so everyone sees not just what changed, but why.
  • Share annotated sessions with teammates to align quickly without long tickets or endless clarification threads.
  • Feed the same session data to AI tools for context-aware suggestions, accurate code generation, or test creation with minimal prompting.
