Integrate in minutes,
not days.
The ultimate tool for designing, testing, and sharing integrations—no coding expertise required.
“This is the fastest way I’ve ever seen to answer the question 'What’s in our backend?’”
Free your engineers from diagram and documentation overhead
Problem
- Outdated or incomplete API collections and documentation
- Slow and frustrating debugging, with information scattered across tabs and tools
- Untested API changes break things in production or cause rollbacks
- Partners and customers hit walls when trying to integrate with your products
- Devs and QA work in isolation and out of sync with CI/CD pipelines, leading to incomplete test coverage and costly post-launch fixes
Solution
- Build and run real-world integration flows with executable API blocks, code snippets, data tables, and visual graphs—all in one place
- Catch breaking changes early and eliminate costly rollbacks
- Accelerate partner and customer onboarding with always-accurate API examples and executable test scenarios
- Align cross-team testing and accelerate release cycles
- Beyond API docs: capture all system architecture and design information
- Replace API client tools like Postman, Insomnia, Bruno, etc

Why Multiplayer Platform Notebooks?
Integration clarity
Get real-time, interactive visibility into how your integrations work, without relying on outdated docs or scattered tools.
Low-Code / No-Code solution
Whether you're technical or not, Notebooks adapt to your workflow. Combine no-code API calls with executable JavaScript, graphs, and tables to build and explain real integrations—faster.
Shareable, self-service documentation
Turn complex integrations into clear, reusable Notebooks. Partners, QA, and customer success teams can run, test, and validate workflows independently—no more email chains or handoffs.
Catch breaking changes early
Track integration logic, API parameters, and workflows as part of your CI/CD process. Avoid costly rollbacks by validating against live services and surfacing mismatches before they hit production.
Faster onboarding
New teammates get up to speed with living, executable documentation. Notebooks replace tribal knowledge with real examples and working test cases.
Collaborate across teams
Notebooks act as the shared, live workspace where developers, QA, product, and partners build, test, and troubleshoot integrations together—without context switching.
Debug with full context
Pair with Multiplayer's Platform Debugger to see what's happening under the hood. Capture deep session replays for every Notebook run—with logs, traces, and metrics included.
Document design decisions
Keep more than just the "how"—record the "why." Capture architectural decisions, product rationale, and system changes in the same space where integrations are tested.
Retain critical knowledge
Notebooks preserve institutional memory. Even if teams change, your integration logic, test cases, and edge cases stay documented, executable, and ready to go.Start for free
