ED5 MMO Studio is a complete standalone MMO engine with a visual editor, browser client, authoritative Node.js server, and PostgreSQL-backed data stack in one package.
Start from scratch or import existing projects from RPG Maker and RPG Tools, then move straight into worldbuilding, balancing progression, and shipping your multiplayer game.
Watch ED5 in action
Standalone MMO engine
Not a plugin or converter — full editor, client, and server included.
Import without rebuilding
Bring RPG Maker or RPG Tools maps and data into an MMO-ready stack.
From prototype to launch
Focus on content and design instead of multiplayer infrastructure.
Standalone Engine
ED5 MMO Studio includes the editor, game client, multiplayer server, content tools, and data layer as one production-shaped engine. You can build from zero or import existing projects into a full multiplayer architecture.
Import + Upgrade
Import maps and existing project data from RPG Maker or RPG Tools, then keep building with MMO-ready systems. Preserve your creative work while upgrading to real-time multiplayer and live world control.
Fast Validation
Start in the browser editor with no install and no card. Review the full documentation, then compare plans on the pricing page when you are ready to ship.
Instead of assembling multiplayer infrastructure from scratch, you start with a production-shaped MMO foundation: world editing, content management, authoritative combat, progression systems, deployment tooling, and room to customize.
Outcome first
Open the full visual editor directly in your browser — paint terrain, manage items, build quests, and configure every game system without installing anything. Same editor as the desktop app, accessible from any machine with a URL. Try it free for 1 hour with no card required.
Start from a full production workflow instead of assembling tools.
Outcome first
Node.js game server with fixed tick loop, WebSocket networking, spatial hash grid, EventBus, and 57+ client-server message types. Delta compression ensures smooth multiplayer at scale.
Keep rules authoritative and stop designing around client trust.
Outcome first
Isometric 2:1 diamond renderer with dynamic lighting (AO, bloom, shadows, vignette), day/night cycle, weather particles, 8-directional movement, entity interpolation, and 54 HUD components.
Ship a browser client players can join instantly.
Outcome first
GCD-based combat with 9 AoE shapes, 22 status effects, 18 weapon types, and full PvP with 5 zone rule types. Plus a complete Pokémon-style pet system with battles, taming, breeding, and evolution.
Launch with progression, PvP, and content loops already wired.
Outcome first
Drop a .ts file into the plugins folder and it auto-loads. 35+ typed events, custom commands, client-server messaging, persistent data store, and full auto-cleanup on unload.
Extend the stack without forking the whole engine.
Outcome first
Combat, crafting, pets, guilds, housing, quests, PvP, economy, and 36 more systems — all server-authoritative. Build desktop launchers or deploy to the web. Edit from the browser or the Electron Studio app.
Move from prototype to deliverable build pipeline faster.
These are not mockups. The screenshots and code samples below reflect the included server, client, editor workflow, and extension surface you receive with the engine.
The full visual editor runs directly in your browser — the same admin panel available in the Electron Studio app. Paint terrain, place mobs, create items, build quests, manage NPCs, and configure all 44 game systems from any device with no download or install. Every account gets a free 1-hour trial — no credit card needed. Add a card to extend it to 7 days. If you bring your own PostgreSQL for Studio Web, it must accept public inbound connections from any IP for now.
Why it matters
Open the editor from any browser and start building worlds immediately — no install, no config.

What those numbers buy you
Fewer blank pages, fewer greenfield systems, and less time spent proving basic MMO loops before your team can move into economy design, content cadence, and launch planning.
How it works
1) Import or start fresh. Bring in your RPG Maker or RPG Tools project data, or begin a brand-new MMO from scratch in the visual editor.
2) Launch the built-in server. Your networking and authoritative game loop are already implemented, so you can test multiplayer immediately.
3) Ship content, not infrastructure. Use included systems for combat, quests, economy, guilds, pets, and live operations while keeping full control of code.
Pay once, keep the source, and ship on your own schedule. No royalties, no recurring engine fee, and no lock-in around the core product.
Choose based on how much delivery leverage and support your team needs, not on which features are artificially withheld.
Everything you need to build and ship your first isometric MMO.
Best for solo builders and first commercial prototypes.
For teams serious about launching a commercial MMO.
Best for teams planning a real commercial release.
White-glove support for studios shipping at scale.
Best for studios that need implementation help and scale guidance.
Indie
Choose this if you want the engine, the tools, and the codebase without extra delivery services.
Studio
Choose this if you want the strongest commercial default and smoother release workflow for a real team.
Enterprise
Choose this if your risk is not price, but implementation speed, team onboarding, and launch confidence.
Secure payment via Stripe. No license activation required. Download access starts immediately after purchase.
If you are still comparing options, read the docs first and come back when you know the level of support your team needs.
“ED5 Studio let us go from concept to live MMO in 3 months. Having 44 systems already wired end-to-end saved us hundreds of hours compared to building from scratch.”
Alex Chen
Lead Developer, Starfall Online
“The plugin system is incredible. We built a full custom event system in a weekend using the EventBus hooks. The auto-cleanup on unload means zero memory leaks.”
Maria Rodriguez
Founder, PixelForge Games
“Best multiplayer architecture I've seen in any 2D engine. Server-authoritative with delta compression just works. No netcode nightmares, no desync issues.”
James Park
CTO, Mythic Realms
“We migrated from a custom engine and shipped our commercial launch 6 months ahead of schedule. The lighting engine and pet battle system alone are worth the price.”

Studio Director, Void Interactive
