Easel – Code multiplayer games like singleplayer

In plain words

Easel is a 2D game programming language designed to simplify multiplayer development. It automatically handles multiplayer networking through deterministic simulation and rollback netcode, allowing developers to build multiplayer games without understanding complex concepts like remote procedure calls. Developers can enable multiplayer by setting a single parameter, and the language enforces multiplayer safety at its core, eliminating common challenges around non-determinism and entity ownership that typically complicate game networking.

Make games. Play together. So easy.

Easel is what happens when a programming language is fundamentally reshaped for making games and only games. Common game concepts like state , behaviors , lifespans , user interfaces , and multiplayer are sculpted into shape of the language, not just the library. That's why it's so fast , so easy and so fun to make games with Easel. pub prop owner . Score = 0 pub game fn World . Main ( maxHumanPlayers = 10 ) { Gravity = @ ( 0 , 10 ) SpawnEachPlayer owner { TopContent { with Score { P ( fontSize = 2 ) { % ( Score > 0 ? Score : "Catch the coins by clicking on them!" ) } } } on ButtonDown ( Click ) { let coin = Pointer . QueryAnyOverlapping ( filter = Category:Default ) if ! coin { continue }…from easel.games

In the maker’s words, at launch

For the past 3 years, I've been creating a new 2D game programming language where the multiplayer is completely automatic. The idea is that someone who doesn't even know what a "remote procedure call" is can make a multiplayer game by just setting `maxHumanPlayers=5` and it "just works". The trick is the whole game…

  I built the first scripting language for multiplayer game devMar 2026 · docs.allout.game · ▲5

  Hi HN, I'm one of the engine programmers at All Out Games (https://allout.game/), a multiplayer-first gaming UGC platform where creators can make and play games with their friends. For scripting we wanted our creators to be able to jump in and create game mechanics without having to think about networking. If a developer had to manually send packets to/from client/server to get things to happen then we have failed. It is particularly bad if you are using AI tools because they struggle to keep in mind what code is meant to run where (client, server, or both) and…

  Multiplayer2025 · multiplayer.app · ▲124

  We built Multiplayer because we kept running into the same problem: coding agents connected to existing observability stacks inherit all the limitations those stacks were built with. Sampled traces, aggregated metrics, context that stops at service boundaries, missing request/response content from deep within the system. The PRs they produce look plausible and fail in production (i.e. “PR slop”). Multiplayer runs locally alongside Claude Code (Codex, Copilot, and Cursor coming soon) and captures full-stack, unsampled session data across your entire system. We collect everything from…

  Hathora – Multiplayer Game Development Made Easy2022 · docs.hathora.dev · ▲89

  Hi HN, this is Harsh, I am the developer behind Hathora. I tried making a simple multiplayer game a few years ago and, as someone with software engineering experience but no gamedev experience, I found it to be very challenging. On top of the challenges of building a single player game, you now have to constantly battle the network and latency, find ways to prevent cheating, and figure out how to make a scalable backend architecture. With Hathora my goal was to encode best practices for online multiplayer game development into a framework so developers can simply focus on implementing their…

  Server-rendered multiplayer games with Lua (no client code)Jan 2026 · cleoselene.com · ▲85

  Hey folks — here’s a small experiment I hacked together over the weekend: https://cleoselene.com/ In short, it’s a way to build multiplayer games with no client-side game logic. Everything is rendered on the server, and the game itself is written as simple Lua scripts. I built this to explore a few gamedev ideas I’ve been thinking about while working on Abstra: - Writing multiplayer games as if they were single-player (no client/server complexity) - Streaming game primitives instead of pixels, which should be much lighter - Server-side rendering makes cheating basically…

  Talanoa▲345

  Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…

  Tapflow 2.0▲1,125

  We built Tapflow for devs, designers, PMs, and tech folks who’ve been sitting on internal docs, templates, and systems — but never productized them. Upload a PDF, notes, or workshop deck, and Tapflow drafts a structured product (with chapters, teaser and pricing plans). It’s good for AI kits, onboarding guides, design systems, and frameworks. You can sell through Stripe, LemonSqueezy, or PayPal. Real-time collaboration is in early beta. No site builder, no LMS — clean design and just focused tools to ship. Fully bootstrapped and just launched on PH today →…
