Capture a full stack session recording once, use it for debugging, testing, support, feature development, and AI prompts. Here's everything you can do in Multiplayer 👀 👇

The best way to ‘win’ at Product Hunt is… not to chase upvotes? 🤔

Product hunt is dead. Here’s what happened as soon as we launched Multiplayer 👇. But here’s also why we did it anyway 🧵

We didn't launch on one of the biggest Product Hunt launch days of the last few weeks to “win”. We launched to share why full stack session recordings matter.

Our first post on Hacker News 🤩 This feels like a rite of passage. news.ycombinator.com/item?id=4537...

Debug faster, validate fixes, and even feed the whole story into your AI IDE. Multiplayer’s full stack session recordings allow you to seamlessly capture and resolve issues or new develop features - without breaking your flow.

We need to stop treating documentation as a static pile of text. The future is documentation as an experience: dynamic, contextual, and part of the workflow. Otherwise, the vicious cycle of outdated docs will never end.

I had the chance to speak at API World 2025 last week on a topic I’ve seen frustrate teams for years: API documentation. Because let’s face it: most developers don’t want to read static docs. Outdated Postman collections and PDF references slow everyone down.

When we build something at @multiplayer.app, we aim for insanely great quality. For example: we’ve been building a sandbox so you can test Multiplayer without signing up for a free trial. Seems straightforward, right? But in practice, there’s a lot to think through 👇

A GTM tip for anyone building for developers: If every feedback call is positive, it means you are only talking to fans and you are not learning enough. Growth comes from talking to people who are struggling with some aspect of your product because its likely they are not the only ones.

There’s a difference between searching the entire game to review a play and seeing it from the player’s helmet cam. --- That’s the difference between observability tools and Multiplayer.

Multiplayer doesn’t try to show you everything. It shows everything that matters for a single bug, test run, or user session. It’s not about coverage; it’s about clarity.

If your AI can write code but can’t help fix bugs, you’re only solving half the problem.

“Works on my machine” isn’t just a joke. It’s a symptom of broken workflows.

❝An information retrieval system will tend not to be used whenever it is more painful and troublesome for a customer to have information than for him not to have it.❞ 👇 That’s why we focused on getting devs *all* the data for a bug, in a single timeline.

If every outage still ends with 'can someone repro this?', you don’t have a reliable test case (👀👇). You have a one-off incident waiting to happen again.

Every minute your engineers spend reconstructing context is a minute they’re not solving problems.

You’re debugging a user-reported slowdown in your platform. The logs look fine. Metrics show a latency spike. But you’re stuck. Unsure if the issue is in your database, a flaky third-party API, or somewhere in your internal service calls.

It’s not “debug once, fix forever.” Unless you’re doing it right, it’s “debug once, waste hours, document never, repeat indefinitely.”

Traditional observability: investigate the crime scene. Multiplayer: catch the bug in the act, with the receipts. It’s time debugging felt like part of the dev workflow—not an incident report.

MTTR is more than a metric. It’s a symptom. Too many silos. Too many tabs. Too little context. Multiplayer helps teams fix what matters: the debugging experience itself.

A man with a watch knows the time. A man with two is never sure. Now imagine: 3 dashboards 4 alerting systems 5 time zones 👋 Welcome to distributed debugging.

One of the biggest bottlenecks in debugging is simply capturing the issue with the right frontend AND backend context. 🪲 Debug smarter, not harder.

Debugging distributed systems is brutal. Reproducing bugs, syncing across teams, and writing tests from memory. It all slows down engineering. With this new Multiplayer feature, with one click you can turn a debugging session into a test script your team can run, edit, and reuse.

No one wants to integrate with a platform that feels like reverse-engineering a puzzle. If you want users to stick around make your integrations easy to explore, run, and share.

As a woman founder in tech, these numbers are frustrating, but not surprising. We’ve known these stats for a while. And that’s exactly why representation in early-stage funding matters so much.

“Eventually consistent” shouldn’t describe your architecture diagrams.

You don’t need more logs. You need a better way to debug.

Come for the AI talk, stay for the tales of documentation trauma and debugging chaos! 😂

Don’t just document what your system *does*. You also need to document *how it came to be*.

Listening to Anthony Alaribe at APIdaysGlobal NewYork! I really enjoyed his talk - lots of interesting insights that I share. 👀 If you’re around, let’s talk API chaos (and how to tame it).

If your idea of debugging a distributed system is opening 6 tabs and guessing…it’s time for something better.

Anyone in New York over the next two days want to talk APIs? I’ll be attending #APIDaysNewYork 👇   It’s my first time, so I’m super curious to check it out! www.apidays.global/new-york/

Jr. dev: Who owns this documentation? Sr. devs:

Engineering teams lose thousands of hours to broken workflows: stale docs, manual debugging, and scattered context. I’m working on a webinar to dig into how AI can help us finally fix that.

Postman collections go stale faster than croissants at a conference. It’s a risky choice to store your source of truth. 🤷‍♀️

Enterprise teams have always seen the potential in Multiplayer, but security is non-negotiable at scale. With this 👇 compliance now in place, we’re making it easier for enterprises to adopt Multiplayer with confidence.

If your diagrams don’t update with your system, they’re not documentation. They’re fan fiction.

Your QA team is testing in isolation. Your devs are shipping in a vacuum. What could possibly go wrong? 😑

Fixing distributed systems with fragmented tools is like solving a jigsaw puzzle in the dark.

Getting your existing architecture into Multiplayer is easy — upload a CSV or a diagram image, and your system architecture is ready to explore.

🙌 No more dragging boxes and arrows. No more outdated diagrams.

Monitoring tells you that its broken. @trymultiplayer.bsky.social shows you why.

QA: *[Explains bug for 10 minutes]* Engineer: “Huh?” QA: *[Sends one Platform Debugger link]* Engineer: “Ohhh.” Moments like these remind me why we built Multiplayer—and why we use it ourselves.

If your partner integrations still require multiple email chains and Zoom calls — you are not self-serve.

Your docs should do more than sit in a wiki. Platform Notebooks are where documentation meets execution: ✅ Document integration steps ✅ Run and debug APIs inline ✅ Share working examples with your team or partners

In this scenario AI would be a shiny new chimney. Looks impressive, adds "innovation points," and it’s installed right next to the hole. Doesn't fix the leak, but it recommends articles about roof repair. 🤣

As a startup founder, how do you reply to: “I’m using [insert tool / in house solution] and I just got it working, I don’t want to switch to something else”?

Most teams still don’t have a clear picture of all the APIs in their system—let alone where they live, how they respond, or how they’re connected. Multiplayer auto-documents it all. Live API detection, automatic documentation, and real-time insights—without any extra effort from your team.

If you tell three people they’ll be having fish for dinner, they might picture entirely different meals—poached salmon, sushi, or fish fingers. Ask three engineers to design a “backend platform for the new app,” and you’ll get three architectures that vary in approach and detail. Alignment is key.
